The aim of this study is to investigate both the planning and implementation process of a modelling task by a middle school mathematics teacher. The participant of the study, which was conducted as a single case study, is a middle school mathematics teacher who have knowledge and experience in modelling. The data collecting tools of this study were the lesson plans of the teacher, the observation notes taken by the researchers during the implementation of the modelling task,the video records of the implementation, students' solution papers and the voice records of the pre- and final-interview conducted with the teacher. Whole data were analyzed according to a framework for modelling implementations developed by the authors through descriptive analysis. The teacher planned his in-class implementation to consolidate the circle concept and revised an existing modelling task by developing appropriate materials for the task. He asked students to arrange their desks appropriate to group work, decided to enable students to evaluate both the implementation and their peers, and announced their students that they would present their group solution and evaluate each other at the end of the lesson. During the implementation, he first reminded prior knowledge about circle and then presented the materials. He shared instructions about group work in the context of sharing social norms and gave information about the peer assessment form, which the students filled at the end of the lesson. During the students were solving the task, he intervened about enabling self-assessment in the groups, considering realistic values and comparing mathematical results with the problem context. In addition, during the solution, he tried to establish socio-mathematical norms by making explanations. After the solution process ended, student groups presented their solution approaches and discussed different solutions by comparing each solutions. Peer assessment form and affective evaluation form regarding the implementation were filled by the students at the end of the implementation. This study contributed the literature regarding modelling implementations and presented a different view about teacher actions in planning and implementing a modelling task.

Correct pronunciation significantly increases the intelligibility of communication. However, it is uncertain whether acquiring the pronunciation of the words enhances word retention capability. Therefore, the major purpose of this research is to evaluate whether vocabulary acquisition with the aid of pronouncing with artificial intelligence leads to a longer memory. In this research, a full experimental pattern, and a pre-test and post-test control group design were applied. Furthermore, a total of 56 high school students aged between 14-15 were asked to memorize unknown vocabulary with two pronunciation teaching methods. Prior to the experimental process, the pre-test was applied to both groups, and then, the artificial intelligence-based speech recognition pronunciation teaching process was to the experimental group while the phonetic alphabet pronunciation process was to the control group on the 4th, 8th, and 12th weeks. According to the findings, it was obtained that pronunciation practice via artificial intelligence-enabled the words to remain in memory longer. Additionally, the participants' views were gathered at the end of the research. For further research, this study will benefit other research with a variety of accessible tools to meet objectives by utilizing a new artificial intelligence-supported pronunciation model, through recording and reacting to learners' pronouncing practices in different languages.

This case study was completed in Fall 2021 with elementary and middle grades pre-service teaching candidates. The goal of the study was to engage candidates in storytelling and reflection of their science identity. Science identity is important as science discourse is historically not diverse. Candidates completed a narrative podcasting assignment within their science methods coursework that asked them to draw upon their experiences. Students were then invited to participate in a focus group during which the authors gathered more insight regarding the candidates' previous experiences and ideas for future teaching. Carlone and Johnson's (2007) Model of Science Identity was used as a framework for this study, which conceptualizes science identity within three intersecting components of performance, recognition, and competence. Conclusions and implications include using reflection in coursework to increase candidates' awareness of bias, support their science identity development, and investigating how narrative podcasting can impact current teaching practices.

This two-cycle action research explores how Colombian students from rural and urban areas construct community knowledge by exploring funds of knowledge using dialogue journals. Thirty-three seventh graders from an urban school participated in the first phase and 19 sixth graders from a rural school and 18 eighth graders from an urban school in the second phase. Data were gathered through journals, artifacts, audio recordings, narratives, focus groups, and interviews. Results revealed how students learned to see and re-signify their communities and territory by exploring the knowledge held by their families and community members. Then dialogue journals were valuable tools to verbalize and communicate their perceptions and understandings about their communities and funds of knowledge.

Interdisciplinarity in the classroom is predominantly championed around a need to address pressing social problems by integrating knowledge from diverse disciplines. But can interdisciplinary teaching take shape without the usual problem-solving frame? And are there new methods/mediums through which to explore interdisciplinarity? These questions have led to new and promising developments related to podcasting, active learning, and interdisciplinarity in the classroom. Through the lens of Travelling Concepts, we reflect on our experiences in the making and using of the podcast series -- Travelling Concepts on Air -- to better understand interdisciplinarity. We show the value of students not only listening to podcasts as a supplementary means of learning, but also creating podcasts as a form of active learning.

Drawing from six-months of action research with spectacle theatre-makers in Chicago, this study explores multimodal, expeditionary practice of teaching artists who apprenticed girls through Redmoon Theatre's Dramagirls program. Concepts of new literacy design and aesthetic experience illustrate teaching in socio-semiotic and material worldcraft, set in motion via intermedial, expeditionary platforms: Imaging, Games, and Dramatizing with Objects. Ethnographic, arts-based analysis of discourse scenarios reveal an emerging aesthetic playground, where teaching artists afford girls imaginative schema to construct socio-semiotic material, felt realities and cultural affinities for a girls' utopia. As this hybrid form of theatre is seldom explored as an aesthetic literacy context, Dramagirls' worldcraft offers pedagogical models for significant youth designs and inquiries.

Traditionally, many English language teachers around the world have conformed to an English as a foreign language (EFL) model. In this model, they expose their students to the standard language norms of English-dominant nations, such as the United States and the United Kingdom. However, English learners do not only need language skills to communicate with native speakers from these nations. As globalization, technology, and migration bring people around the world into more frequent and sustained contact, learners also need to be able to engage with other speakers of English as an additional language. Therefore, a more appropriate model is English as an international language (EIL), which emphasizes users' ability to communicate with diverse global English users. To help students develop these abilities, teachers can use diverse listening materials that expose students to varied language models. In this article, we recommend podcasts as a rich source of diverse listening materials. Although we recommend using podcasts in intermediate- or advanced-level classes, with appropriate planning podcasts can be used even with beginner students. Below, we first explain what podcasts are and how they help students develop listening skills. Then, we describe strategies to include podcasts in listening lessons, based on our experiences in a listening course for first-year English major students at an Islamic university in Central Java, Indonesia. Finally, we share feedback from our students to offer recommendations for teachers interested in using podcasts in their own listening lessons and courses.

This study aimed to reveal the solutions of pre-service teachers to contextual problems related to number bases other than the base ten. Furthermore, it was intended to investigate which issues pre-service teachers discussed about their learning in the problem-solving process, including context, and about student learning in their future teaching practices. To achieve this, task-based interviews were held with 12 pre-service primary school teachers. During semi-structured one-on-one task-based interviews, some questions were asked to reveal preservice teachers' way of thinking about the problems and their reflection on the learning. In this context, data were obtained from the audio recordings and the students' written responses. Besides, researchers' notes are used as supporting documents for the validation of the data collection process. The main findings of the study revealed that context is a facilitator for preservice teachers in understanding number bases other than base ten. They gained insight and provided instructional explanations on how to teach the student by understanding the different number bases. Furthermore, context enabled preservice teachers to reflect on how to teach better by considering their own learning processes.

In this study, 56 participants' (N=56) perceptions towards dual coding in design of audio-only listening texts (i.e. re-provision of the same audio-only listening texts in the form of audio-only listening texts + keywords or supplementary contextual visuals + keywords at non-initial phases of the while listening stage) in a hypermedia listening application for foreign language learning (FLL) were investigated. The study also investigated whether there were any differences between the participants' perceptions in terms of gender, age, job and FLL period. The study was both quantitative and qualitative in nature. The results of the study were analysed with SPSS (i.e. Mean, Std. Deviation, Independent Samples t Test, ANOVA, Pearson Correlation test, Chi-square). The results revealed that the language learners (LLs) were overwhelmingly in favour of the use of the dual coding in design of audio-only listening texts (i.e. re-provision of the same audio-only listening texts in the form of audio-only listening texts + keywords or supplementary contextual visuals + keywords at non-initial phases of while listening stage) in a hypermedia listening application for FLL. The majority of the LLs believed that not only did such a design benefit them in different ways, but it also contributed to the enhancement of their learning. The participants also felt that such a design could and should have been further improved. Moreover, the results revealed that there were significant differences between the participants' perceptions towards the re-provision of the same audio-only listening texts with keywords, and (supplementary contextual) visuals + keywords.

Previous studies have shown positive effects of self-assessment on L2 English learners' speaking performance, but it is unclear whether the same is true with peer assessment. Research is also scarce on the effects of such assessments on the learner's sense of autonomy. This study thus investigated the effects of self- and peer-assessment on L2 English speaking performance and learner autonomy. To take advantage of the information communication technologies in assessment, the online platform VoiceThread was used. While all participants received feedback from the same instructor, only the experimental group, known as the "online assessment group" used VoiceThread to narrate a self-assessment of their own uploaded speech videos and to narrate peer-assessments of their classmates' uploaded speech videos. Quantitative and qualitative data were collected from the 39 participants majoring in English at a 4-year college in Taiwan. Results showed that the experimental group outperformed the control group in both speech performance and sense of learner autonomy. In an open-ended survey, participants in the experimental group also expressed confidence that the online self- and peer-assessment helped them become better English speakers. These findings suggest that with proper guidance, L2 learners can become more proactive in improving their speech performance.

Podcasts are audio files that are automatically delivered to the student's computer, smart phone, iPad or MP3/MP4 player. They can be automatically updated. Students typically subscribe to podcasts using "podcatcher" software such as iTunes. The present study proposes a model for integrating grammar podcasts in teaching English grammar to EFL/ESL college students. It gives examples of English grammar podcasts that can be integrated in in-class grammar instruction. It shows how grammar podcasts can be downloaded and used and some of the grammatical structures and topics are covered by those podcasts. Grammar podcasts contain 2-5-minute-long audio explanations of a particular grammatical point or structure. They include a lesson script, exercises, quizzes with an answer key, and/or an English grammar help where answers are given to students' questions about problematic grammatical points. Students can download podcasts, print the script, do the exercises and score their answers themselves. Elementary, intermediate, and advanced level grammar podcasts can be downloaded depending on the students' needs and proficiency level. Unlike face-to-face classroom lectures, students can listen to grammar podcasts anywhere, anytime and as many times as they need. Classroom discussions on a grammar podcast can be performed in pairs, small groups or even whole class. End-of-semester grammar tests can be given to find out improvements in the students' grammatical knowledge/achievement as a result of integrating grammar podcasts in EFL grammar courses. Recommendations for the effective use of grammar podcasts are given.

Toppling the statue of the slave merchant Edward Colston in Bristol, removing the monuments of King Leopold II from public places in Belgium, Black Lives Matter protests, and mass demonstrations targeting remembrance of certain chapters of the history of the Global North -- these are some of the significant events that drew attention to the ongoing disputes around the legacy of colonialism during the summer of 2020. These developments form an integral part of the long-drawn-out process of decolonisation: decolonising the culture of the former mother countries. From museology through the natural sciences and linguistics to visual arts, vast areas of the academic, scientific, and cultural scene of the Global North are crucially affected by decolonizing tendencies, with the teaching of history arguably among the most disputed ones. This paper reviews the key decolonising aspirations of history teaching in the United Kingdom by studying the goals, messages, methods, and endeavours of three movements: "Why Is My Curriculum White?," "The Black Curriculum," and "Rhodes Must Fall Oxford," address different levels of education and urge the transformation of numerous aspects of history teaching (teacher training, curricula, teaching methodology, etc). Source materials examined include the work, teaching aids, and written, audio, or video content published on various social media platforms by these three organisations, as well as parliamentary papers and reports of public and non-governmental bodies.

Audacity is a multi-platform free, open-source audio recorder and editor software. The advantage of Audacity software is as follows: easy installation and simple visual interface, no registrations or hardware requirements, and availability at no cost might make it a preferred software to carry out class demonstrations and lab activities for an undergraduate course in the Communication Sciences and Disorders discipline. The tutorial aims to illustrate how Audacity software can be used to demonstrate various psychoacoustic phenomena commonly taught in undergraduate Hearing Science courses. This tutorial is divided into fundamental and advanced concepts from the pedagogy and student learning standpoint. The fundamental concepts involve using sine waves to demonstrate frequency, amplitude, and phase related to auditory perception. The advanced concepts include the generation of complex periodic non-speech signals, wave superposition, beats, missing fundamental frequency, demonstration of different filters, and amplitude and frequency modulation. Future research is needed to evaluate the benefits of using Audacity software for psychoacoustical demonstrations in an undergraduate Hearing Science course.

This paper extends the use of Generalizability Theory to the measurement of extemporaneous L2 speech through the lens of speech perception. Using six datasets of previous studies, it reports on "G studies"--a method of breaking down measurement variance--and "D studies"--a predictive study of the impact on reliability when modifying the number of raters, items, or other facets that assist the field in adopting measurement designs that include comprehensibility, accentedness, and intelligibility. When data from a single audio sample per learner were subjected to D-studies, we find that both semantic differential and rubric scales for comprehensibility were reliable at the 0.90 level with about 15 trained raters or 50 untrained crowdsourced raters. In order to offer generalizable and dependable evaluations, empirically informed recommendations are given, including considerations for the number of speech samples rated, or the granularity of the scales for various assessment and research purposes.

It is commonly accepted that educators who prepare to teach materials to meet student needs should cover all skills in English, such as speaking, listening, reading, and writing with additional grammar and vocabulary according to the level of students. Because technology has developed rapidly, educators can design technologically friendly teaching materials or textbooks for mobile phones. One recommendation is using quick response (QR) codes where students can scan and learn to listen to the audio while reading the text provided in the textbook. This activity, listening and reading simultaneously or consecutively, is called the meaning-focused input learning approach. This study used 2D out of 4D (four-D) development model by Thiagarajan (1974), namely, define and design to inform (1) the steps for embedding QR codes in the textbook and (2) to run QR code scanning systems in English textbooks. In the definition stage, the authors performed the following diagnoses: learning activities analysis, learner analysis, task analysis, and concept analysis. Meanwhile, for the design stage, the authors presented QR codes as teaching materials in textbooks compiled through the steps of free, quick, and easy applications, namely 1) converting texts to audio files using the apps Text to Speech (TTS) Free; 2) merging the audio files using Clideo; 3) uploading the audio files into Google Drive; 4) creating QR code through QR code Generator to embed into textbooks. The results of this study contribute to materials development in many ways and assist stakeholders in education, such as EFL teachers, curriculum designers, and policymakers.

A large number of research studies have highlighted the relevance of oral narratives for describing children's linguistic constraints, developmental stages of narrative discourse patterns, and sociocultural identities. Yet, little research has been found on the use of oral narratives as a means to longitudinally improve oral discourse coherence and fluency in English as a Foreign Language (EFL). This article reports a case study which was aimed at exploring and describing oral language enhancement in 26 Chilean preservice teachers of English through the implementation of oral narrative tasks over four months. Oral narrative samples were collected through audio recordings, then transcribed and analyzed through the Narrative Assessment Profile, and analytic rubrics elaborated in light of the literature review carried out for oral fluency. Findings suggest a relation between oral narrative tasks and oral discourse coherence and fluency improvement, with a large effect size (25% for social sciences) on oral discourse coherence. Also, a new measure and dysfluency indicator of L2 oral fluency was discovered and defined as false reformulation. It could be concluded that oral narrative tasks might constitute a valuable instrument for enhancing oral English as a foreign language over time.

Socratic pedagogy is a systematized method that encourages learners to question themselves and each other - without being judgmental. It aims at boosting empathy and developing an ability to reach informed conclusions. It supports the acquisition of social skills and fosters collaboration while helping them to think critically, deepen their understanding, and find reality in equilibrium. In reaching for insights, students acquire vital skills, knowledge, and practices. Socratic learning depends on how participants can use systematic dialogue. This study monitored the effects of students' use of specific discourse markers (DMs) over a series of speaking tasks undertaken in Socratic seminars. Each task was devised to support the learning objectives of a standardized English language course given to pre-service English teachers in Turkey. Recordings were used to provide feedback to ten participants and then analyzed for appropriate use of spoken DMs. The findings of the study revealed solid evidence of accurate and contextually appropriate DM usage as the number of appropriate DM use increased significantly in the seminars conducted at the end of the intervention period.

With the emergence of data science as an inherently multidisciplinary subject, there is increasing demand for graduates with well-rounded competence in computing, analytics, and communication skills. However, in conventional education systems, computing & quantitative, and communication skills are often taught in different disciplines. Data storytelling is constructing and presenting data stories to highlight the analytical insights to achieve the communication goals to a specific audience. Digital data storytelling leverages digital storytelling techniques and best practices in communication to deliver stories that can be shared in digital formats to a wide audience. In this paper, we describe and reflect on a semester-long project-based learning pilot using Digital Storytelling as a framework to allow students to explore topics themed around human flourishing and sustainability with the end goal of constructing data stories delivered in digital or video format (i.e., Digital Data Storytelling). The pilot work was conducted in an introductory data science course at a 4-year Minority Serving Institution in collaboration with students studying non-STEM disciplines at a partner community college. Our pilot demonstrates the potential benefit of this sustainability-aware Project-Based Learning design in raising students' awareness of sustainability issues, increasing confidence in cross-disciplinary communication competency, and at the same time deepening their understanding of data science concepts. We further reflect on the significant role of an effective program model as well as challenges and opportunities for building transdisciplinary communication competency to prepare for a diverse data science workforce.

Podcasts can have a positive impact on students' online experiences in higher education. University students in groups of 5-7 created podcasts for an online Survey of Diseases and Disabilities course. To facilitate quality podcast creation, we identified the best mobile application tools using the Mobile Application Rating Scale (MARS). MARS is an easy-to-use multidimensional app quality rating scale requiring minimal training useful for selecting the highest performing podcast software to aid students in generating high-quality podcasts. After creating their podcasts, the students completed a survey about their experience to determine their perspectives of audio podcasts in relation to course content review and to identify the locations where students primarily listened to the podcasts. Most students felt that the summarization components of the podcast assignment improved their understanding of class content and listened to the podcasts at home or on a walk. Students with competing demands appreciated the flexibility podcasts provided, particularly if they were auditory learners. When implementing new technology, we recommend investing time upfront to evaluate digital technology to maximize student learning.

An instrument was validated through factorial structure to measure the advantages, levels of reflection, and communicative competencies of the podcast, as well as to establish the levels of reliability and consistency of the measuring instrument. Likewise, confirmatory analysis was carried out to validate the proposed structural model and establish the relationships of the factors using the PLS-SEM methodology, Partial Least Squares Structural Equation Modeling. It was validated with a sample of 142 teachers. It was demonstrated that there is a causality relationship of the variables, given by the coefficient of determination R2, the level of influence of the independent variables: levels of reflection and advantages; on the dependent variable, communicative competencies; the level of influence of the exogenous variable: advantages with the endogenous variable: levels of reflection in teachers. A high degree of construct validity was shown through the fit indices of the confirmatory factorial analysis.

Podcasts have increased in popularity in the last decade, but description of their use in academic settings is lacking. The purposes of this study were to (1) investigate the difference in student performance on course examinations based on podcast usage and satisfaction and (2) examine the perceptions of educational benefits, usage preferences, and accessibility of podcasts in a clinical examination course in a hybrid Doctor of Physical Therapy (DPT) curriculum. This was a mixed-methods study that utilized a retrospective non-experimental correlational design, and data were collected and analyzed via self-report survey. Participants adopted five podcasts into learning and studying activities. An ANOVA indicated that there was a statistically significant (p = 0.01) difference in examination performance for podcast usage in the fourth episode, with those who listened more performing better. Level of agreement in podcast satisfaction had little impact on academic performance on examinations. A total of six themes emerged from qualitative analysis: podcasts provided listeners a supplementary study tool, connected the learner to the real world, and allowed convenient listening and multitasking. Listeners noted the experience could be enhanced by an improved streaming platform, preferred shorter-duration podcasts, and recommended podcasts to future cohorts. In a sample of 27 first-year hybrid DPT participants, 100% reported overall satisfaction with podcast content and would recommend them to future cohorts.

With the lockdowns of the COVID-19 pandemic and increasing popularity of videoconferencing software such as Zoom, the move to online and /or hybrid teaching has never been more rapid. With this change, however, maintaining presence in the classroom has become a great challenge simply because of the nature of online teaching. Presence is a teaching quality that enables the teacher to "own the room" and create an atmosphere of focus and inspiration. With the loss of face-to-face contact and the diminution of body language that online teaching entails, the teacher has to rely more and more on their own voice to hold presence in the class. While voice has always been an important tool in the teacher's expressive armoury, it takes on a more central role in online teaching and can be the only element that connects teachers to students. Yet many teachers still front classes where voice audio quality is severely restricted due in part to poor choice of microphone and setups on their behalf. In this article I will discuss the notion of presence in online classrooms with regard to voice, and show how teachers can maintain and manipulate this feature in order to retain appeal for students.

Reflection in language learning plays a key role in promoting a deeper understanding of one's own learning. Previous studies show that reflective speaking could raise students' higher critical thinking, and that technology helps facilitate this reflection effectively. This study aimed to investigate the use of VoiceThread for a reflective speaking task for students. The participants consisted of 67 undergraduate students enrolled in an English course who were assigned to do four video recordings of their self-study. They found their own English materials to study and made their own choices of answering the five guided questions representing the four reflective levels. Only 156 video recordings from out of 39 students, who posted all four video recordings, were transcribed and analyzed. All 67 students did answer the questionnaire regarding their attitudes towards the use of VoiceThread. The findings show that the majority of the students' reflective level was at Level 1 ("Non-reflection"), and a few of their expressions were found at Level 3 ("Reflection"). The students also said they were confident when speaking, and VoiceThread helped facilitate their reflective speaking.

This study investigated the effects of two types of classroom instructions on EFL learners' oral proficiency by implementing teachers' judgment. Two intact classes of EFL university students studied a compulsory subject of their department under two different types of classroom instruction. The first group of students was trained with explicit oral strategy training instruction, which taught them to learn and practice strategies to improve their speech fluency. The second group was instructed to practice the task twice as much as the first group using implicit task-based instruction. The audio recording of both groups' oral task performance in the pre-test and post-test conditions were rated for proficiency, pronunciation, discourse, vocabulary, grammar, and complexity. Two English teachers were trained to rate the recordings based on two oral proficiency rubrics. The non-parametric tests and estimation analysis results showed that both groups' oral proficiency improved significantly, with effect sizes ranging from medium to large. The comparison of both groups' results showed that the two types of instruction had a comparable effect on students' oral proficiency. The current study's findings suggest that the use of teachers' judgments can be necessary for classroom-based studies to measure the effects of instruction on gains in learners' oral proficiency.

The research aimed to assess the English reading comprehension skills of fifth-grade Bhutanese students through a comparison before and after implementing the audio-assisted reading strategy. Additionally, it aimed to investigate the extent of their learning satisfaction towards the use of this strategy. The research was carried out in one of the primary schools in Bhutan for a period of one month. The study adopted a quasi-experimental design employing both qualitative and quantitative methods. Lesson plans were used as the interventional tools while reading comprehension tests and semistructured interviews were used for the collection of quantitative and qualitative data, respectively. The quantitative data were analyzed using a paired sample t-test, and the qualitative data were analyzed using the thematic analysis technique. The analysis of the pretest and posttest scores revealed that the mean score of the posttest was greater than the mean score of the pretest. The data collected from the interviews revealed that the participants were motivated and satisfied with the use of audio-assisted reading strategy. The study recommends incorporating the audio-assisted reading strategy as an effective reading strategy to enhance the reading comprehension skills of the students.

This IRB-approved qualitative case study was grounded in Vygotsky's (1978; 1987) socio-cultural constructivism theory and New London Group (1996) postulates of multiliteracies. The participants in this project were 12 domestic and international polylingual English as an Additional Language students at a public university in one of the north-eastern states in the United States of America. The data was collected via site and participant observations, analytical notes and memos, surveys, audio-recorded and transcribed interviews, and artifacts in the forms of the reading comprehension tests to two different texts. One of the texts was supported by an audio recording, another one had a video support with the sound track. All the data was coded using Saldaña's (2012) thematic and value coding and triangulated in the process of analysis. The findings of this study indicated that all 12 research participants strongly relied on the means of multimodality while reading the texts and working with the comprehension test questions. All participants in this study found video mode as most helpful to them, followed by the auditory one in the process of their meaning making of the text, which they found complex. Major implication of this study is that multimodality needs to be embedded in the higher education curriculums in order to assist students, including but not limited to the polylingual EAL leaners with reading and meaning making.

This research is a pre-experimental study conducted with the following objectives: 1) to investigate the efficiency of using podcast in developing English listening skills for; 2) to compare the achievement of English listening comprehension before and after the repetition technique using podcast; 3) to examine the satisfaction with the intervention of using the repetition technique with podcast to enhance English listening skills for comprehension. The sample group consisted of 41 second-year students. The selection of the sample group was done through purposive sampling, whereby the sample group had to meet the language proficiency standards of level A2 or B1 according to the Common European Framework of Reference for Languages (CEFR). The experimental period spanned 11 weeks, with a total of 22 hours. The research instruments were podcast clips, practice exercises, pre and post-tests, and satisfaction questionnaire. The research findings revealed that the efficiency of using podcast in developing English listening skills for comprehension exceeded the predefined criterion of 80/80, with a score of 88.51/86.59. Moreover, when comparing the scores for the post-test English listening skills for comprehension of students using the intervention of using the repetition technique with podcast to enhance English listening skills for comprehension, it was found to be significantly higher than the average pre-test scores at a statistical significance level of 0.05. Overall, the students expressed a high level of satisfaction with the intervention of using the repetition technique with podcast to enhance English listening skills for comprehension. The average satisfaction score was 4.50.

Understanding science allows students with and without developmental and behavioral-based (DB) disabilities to better appreciate the world around them as well as prepare them for the growing science-related job market. However, students in the United States consistently underperform on science achievement tests compared to students from other nations. This underperformance could be attributed, in part to science having many specialized vocabulary terms that are not often taught explicitly, leaving students with incomplete or inaccurate understandings of word meanings. Improving science vocabulary instructional practices may support students with and without DB disabilities in enhancing their science achievement. To address this need, researchers implemented multicomponent multimedia professional development (PD) to support middle-school science teachers in delivering high-quality vocabulary instruction in inclusive settings. In this paper, data collected from a study evaluating the efficacy of the PD were analyzed to determine the influence on student outcomes using ANOVA and multilevel modeling methodologies. Though initial results indicate a promising impact on teacher instructional practices, little is known whether teacher participation in the PD affected student science vocabulary and content knowledge growth. Using multilevel modeling, student science knowledge growth was evaluated following their teachers' exposure to the PD. The findings from this study indicate having indirect exposure to PD had a positive effect on science content knowledge for students with and without DB disabilities (N = 980). In addition, the authors found students with DB disabilities whose teachers had access to PD showed a larger gain in science knowledge than general education students whose teachers did not have access to the PD.

New media formats such as podcasts are revolutionizing the production and dissemination of knowledge in and outside of higher education. One danger is the rise of EdTech companies that have used the pandemic as an opportunity to increase profits as more individuals and systems of higher education rely on digital platforms and products. This report explores the revolutionary potential of podcasts as an education technology that does not necessarily further the privatization of education. The case of the FreshEd podcast is highlighted.

As an alternative solution to solve different reading comprehension problems in learning English as a foreign language (EFL), it is necessary to implement a blended learning model that combines both online and face-to-face (f2f) teaching modes. This study aimed at investigating the impact of blended learning on Iranian intermediate EFL learners' reading proficiency. Sixty EFL learners were chosen based on their performance on Oxford Placement Test. Then, they were divided into two groups (an experimental and a control group). The experimental group received reading materials through blending learning techniques and the control group received training in the traditional way. During treatment, the teacher designed and assigned activities for students to read the text effectively and reinforce their comprehension. The activities were designed to teach reading like scanning, skimming, and reading for accurate comprehension. Afterward, both groups participated in the reading post-test at the end of the study. The results showed that the experimental group outperformed the control group in the post-test of reading comprehension and the intra-group progress was higher for the experimental group than the control group.

This work aims to advance on the systematization of teaching experiences in the formulation of evaluation activities, mediated by ICT, for academic and professional training in the field of Political Science. It explores the usefulness of student podcasting as a didactic strategy for theoretical-active learning in digital university environments during COVID-19 pandemic. Based on the design of an assessment questionnaire and a nonprobabilistic convenience sampling strategy, a survey has been administered to N=40 students from two theoretical undergraduate courses of the School of Political Science at the University of Costa Rica, taught during two semesters in 2020. The article reviews the related results according to the degree of satisfaction with podcasting as a way of evaluating the appropriation of theoretical content. It is concluded by arguing that this teaching-learning methodology helps to facilitate among students' new ways of "putting theory into practice", this through the exercise of creative, reflective skills and theoreticalconceptual argumentation according to the creation of student-made podcasts, based on work on theoretical lines and conceptual proposals of relevance to Political Science.

Repeated viewing of the same video is a common strategy among autonomous language learners as well as a much used pedagogical strategy among foreign language (FL) teachers. Learners may watch the same video more than once, to increase global comprehension of the target language or to focus their attention on linguistic aspects, such as new vocabulary or pronunciation. This study sought to examine to what extent repetition is more efficient for vocabulary learning if the second viewing follows the first immediately, or a week later. Participants were upper intermediate-level college learners who were distributed into three groups, one watched a TV series episode twice in the same session, one also watched the same episode twice but one week apart, and the last (control) group did not watch the video. Tests of word meaning recognition and word meaning recall were administered before and after viewing (pretest-immediate posttest-delayed posttest). The pretest and posttests contained 23 target items and 17 distracters (single words and multi-word expressions). In addition, the study explored the influence of two learner factors, each related to one of two verbal input channels: sound recognition for the audio and reading efficacy (reading speed and comprehension) for the onscreen text. The results indicated significant vocabulary learning from viewing and slightly higher benefits for the spaced repetition group at immediate posttest. The results also showed a significant influence of previous target vocabulary knowledge and of aptitude, as measured by the LLAMA D test, but not of reading efficacy.

Purpose: The current standard for clinical diagnosis of childhood apraxia of speech (CAS) is expert clinician judgment. The psychometric properties of this standard are not well understood; however, they are important for improving clinical diagnosis. The purpose of this study is to determine the extent to which experts agree on the clinical diagnosis of CAS using two cohorts of children with mixed speech sound disorders (SSDs). Method: Speech samples of children with SSDs were obtained from previous and ongoing research from video recordings of children aged 3-8 years (n = 36) and audio recordings of children aged 8-17 years (n = 56). A total of 23 expert, English-speaking clinicians were recruited internationally. Three of these experts rated each speech sample to provide a description of the observed features and a diagnosis. Intrarater reliability was acceptable at 85% agreement. Results: Interrater reliability on the presence or absence of CAS among experts was poor both as a categorical diagnosis (K = 0.187, 95% confidence interval [CI] [0.089, 0.286]) and on a continuous "likelihood of CAS" scale (0-100; intraclass correlation = 0.183, 95% CI [0.037, 0.347]). Reliability was similar across the video-recorded and audio-only samples. There was greater agreement on other diagnoses (such as articulation disorder) than on the diagnosis of CAS, although these too did not meet the predetermined standard. Likelihood of CAS was greater in children who presented with more American Speech-Language-Hearing Association CAS consensus features. Conclusions: Different expert raters had different thresholds for applying the diagnosis of CAS. If expert clinician judgment is to be used for diagnosis of CAS or other SSDs, further standardization and calibration is needed to increase interrater reliability. Diagnosis may require operationalized checklists or reliable measures that operate along a diagnostic continuum.

The podcast is a tool that economic educators can employ in the classroom as an alternative approach to convey content. Using a unique quasi-experimental approach in four undergraduate economics classes, we measure student perceptions of podcast use and the effectiveness of the podcast as a pedagogical tool in the economics curriculum. This experiment controls for demographic characteristics, educational background, learning styles, instructor fixed effects, and class fixed effects while measuring the impact of podcast use on student learning outcomes. We find that exam scores of students assigned podcasts to supplement their learning were statistically no different than those of students assigned printed news articles to supplement their learning. However, in terms of perception, students believed they were learning more from podcasts than news articles.
