Biology education plays a vital role in nurturing the understanding of learners about the intricacy of life. Various efforts have emerged to strengthen learning biological concepts but there were still studies that showed that learners have low mastery in some aspects. To determine how well students understood various biological topics, including human physiology, Concept inventory tests (CIT) were used. The concept inventory test may be able to spot students' misconceptions and ultimately lead to improved comprehension. The crafted CIT developed with the aid of a table of specifications based on Bloom's taxonomy of cognitive domain was assessed according to its validity and reliability. In validation, content validity and item analysis were considered while reliability test was employed through Cronbach's alpha. Distractor analysis was also performed to determine possible source of misconception per item. The CIT was administered to 120 senior high school STEM students (50.8% from the private schools, 37.5% in regular public schools and 11.7% from public schools with special programs in science). The results displayed high content validity with a mean of 4.83 for content validity and an average Aiken's validity coefficient of 0.98. It also highlighted that the test is moderately difficult with the test difficulty of 0.58, as well as, discriminatory with a discriminating level of 0.46. After item classification, 63 items were retained (39 accepted, 24 for revisions) and Chronbach's alpha ([alpha]=0.74) indicated good internal consistency. The concept inventory test propounds to be a good classroom test science with minor items to be revised.

Objectives: This study aimed to analyze how pedagogical practices and affective states during emergency remote teaching influence professors' perspectives on their capabilities and the professor-student relationship. Method: We used a nonexperimental quantitative design, collecting data through an online survey during the first year of the pandemic. Participants were recruited using a non-probability sampling method. A total of 636 university professors from Chilean universities participated. We performed descriptive and correlation analyses between variables. Also, to gain a deeper understanding of the factors influencing perceptions of the professors' competence and the professor-student relationship, we conducted linear regression models. Results: A higher perception of pedagogical competence was related to male professors reporting a high evaluation of teaching quality and a high diversification of assessment strategies. A better professor-student relationship was related to female professors reporting a high level of tutoring activities and activities in which students work collaboratively. Additionally, unpleasant affective states were experienced at a higher rate by younger and female professors. Conclusions: Variables that make up the perception of professor competence and the professor-student relationship were identified, relating to gender and pedagogical practices, such as diversification of assessment strategies, tutoring, and collaborative activities. Implications: The results can guide future institutional actions to improve conditions and establish guidelines for quality virtual education in the post-pandemic scenario.

This study aimed to describe the profile and practices of school nurses working at a network of educational centers in Spain. This was a descriptive study of the documented actions of 107 school nurses between September 2018 and June 2021 in 54 educational centers (55.6% private and 44.4% subsidized). The profile of the school nurses was young (average age 33.8 [standard deviation (SD) = 7.7] years) and predominantly female (91.6%) with a diverse and multidisciplinary education, primarily at the postgraduate level (specialized mainly in emergency care, nursing/school health, and pediatrics/neonatology). They carried out 256,499 interventions. The most frequent types of incidents they treated were accidents (30.4%) and disease-related episodes (22.2%). The interventions were usually brief (average time 7.7 min) and were resolved by the school nurse (99.1%), and the main recipients were students (87.3%). The highest incidence of interventions occurs during breaks between classes. Acute interventions occupied most of the school nurses' time, leaving little opportunity for health education (0.3%). School nurses played an important role in preserving and promoting the health of school populations and cost-savings to healthcare systems with the actions that they performed. Descriptions of these actions are essential when advocating for the continuation and expansion of school nursing services.

Community colleges were established as affordable postsecondary education opportunities for all residents within their local areas. Typical measures of access to postsecondary institutions use binary indicators based on the presence of institutions within geographic areas or straight-line distance between student residences and college locations as the underlying metric and implicitly assume that students travel by private vehicles. These factors likely overestimate access within urban areas where relatively large proportions of residents may commute primarily by public transit. In this paper we estimate access based on travel times to community colleges in ten large U.S. cities utilizing public transportation, examine variations in access across those cities, and compare these estimates to distance-based measures of access. We find that access to community colleges based on public transit travel times varies substantially within and across cities and is influenced by each city's geography and built environment. We conclude with a discussion of how measuring college access by travel time reveals the existence of urban community college access deserts.

The role of top-down control in divergent creativity remains heavily debated. An outstanding question about the state dynamics of creativity concerns acute shifts between heightened and lowered creative states. Particularly, do transitions between creative states incur a "switch cost" as observed in other domains of cognition? Prior research showed that asymmetric switch costs are often incurred such that reaction time is asymmetrically slower when participants switch from a task involving more top-down control to a task involving less top-down control. We tested the hypothesis that frequent acute transitions from creativity-cued responding (associated with heightened creative state) to uncued responding (associated with lowered creative state) would incur an asymmetric switch cost such that uncued responding would be disproportionately impacted by state changes. We utilized the "thin slices" verb generation task in a task-switching paradigm. Consistent with the hypothesis of asymmetric switch costs in shifts between creative states, we observed a substantial switch cost when switching from creativity-cued trials to uncued trials, but no switch cost when switching from uncued trials to creativity-cued trials. These findings provide indirect evidence that heightened creative states may require substantially more top-down control than lowered creative states, supporting the theory that divergent creativity requires increased top-down control.

We present as a case study the evolution of a series of participant-centered workshops designed to meet a need in the life sciences education community--the incorporation of best practices in the assessment of student learning. Initially, the ICABL (Inclusive Community for the Assessment of Biochemistry and Molecular Biology/BMB Learning) project arose from a grass-roots effort to develop material for a national exam in biochemistry and molecular biology. ICABL has since evolved into a community of practice in which participants themselves--through extensive peer review and reflection--become integral stakeholders in the workshops. To examine this evolution, this case study begins with a pilot workshop supported by seed funding and thoughtful programmatic assessment, the results of which informed evidence-based changes that, in turn, led to an improved experience for the community. Using participant response data, the case study also reveals critical features for successful workshops, including participant-centered activities and the value of frequent peer review of participants' products. Furthermore, we outline a train-the-trainer model for creating a self-renewing community by bringing new perspectives and voices into an existing core leadership team. This case study, then, offers a blueprint for building a thriving, evolving community of practice that not only serves the needs of individual scientist-educators as they seek to enhance student learning, but also provides a pathway for elevating members to positions of leadership.

High school exit exams are meant to standardize the quality of public high schools and to ensure that students graduate with a set of basic skills and knowledge. Evidence suggests that a common perverse effect of exit exams is an increase in dropout for students who have difficulty passing tests, with a larger effect on minority students. To mitigate this, some states offer alternative, non-tested pathways to graduation for students who have failed their exit exams. This study investigates the post-secondary effects of an alternative high school graduation program. Compared with similar students who fail to complete high school, those students who take the alternative pathway have better post-secondary outcomes in both education and employment. Compared with similar students who retake exit exams to graduate, those who eventually graduate through an alternative project-based pathway have lower college enrollment, but similar employment outcomes.

Anchored on Evans' professional development (PD) model, this study aimed to develop, implement, and evaluate a professional development program on designing participatory action research (PAR) projects for basic education teachers. The teachers are from Junior and Senior High School teaching English, Mathematics, and Science. The PD program consisted of ten in-person training sessions and virtual consultations which happened in between training on AR problem conceptualization and methodology for a 14- week period. Using the mixed-methods sequential explanatory (QUAN [right arrow] qual) design, the study started with a professional needs assessment participated by 18 teachers from a secondary school as a basis for the planned PD program. The teachers underwent training sessions to develop a group or participatory AR proposal as evidence of their professional growth and program outcome. At the end of the program, the English, Mathematics, and Science teachers, respectively, developed and presented their AR proposals on the (a) design and evaluation of a gamified-based instruction towards improving vocabulary skill, (b) video-based instruction in teaching basic concepts of probability, and (c) investigating the effect of contextualized learning materials in developing students' conceptual understanding of atoms. The post-assessment results, supported by interviews, revealed that the teachers displayed behavioural, attitudinal, and intellectual developments in AR. Based on the Department of Education's criteria for evaluating PAR proposals, all three proposals were rated acceptable for implementation by a panel of evaluators. In conclusion, the PD design and evaluation framework were important factors that enabled the participating teachers to transform their AR competencies toward developing PAR proposals for improving teaching and research in their schools.

This study aimed to examine the initial perceptions of 16 junior and senior high school English, Mathematics, and Science teachers on AR (Action Research) as the basis for the planned professional development program. The evaluation of their initial perception was done by administering an instrument called Teacher's Perception on Action Research (TPAR). This is a research-made instrument containing scenarios which either represent an AR scenario or not but can elicit teachers' perceptions about AR specifically on its nature of purpose and process. An in-depth individual (IDI) semi-structured interview was also conducted to obtain in-depth data on each participant's perception about AR. Results revealed that their initial perceptions on the nature of purpose can be thematized into AR as a reactive approach for addressing problems in a positivist or scientific research method and as a mechanism for seeking transformative change. Meanwhile, their alternate perception on the AR process rests on the research method being reversible, reflective, and collaborative. However, these initial perceptions about AR were not discussed in-depth by the participants suggesting the need for a professional development program among these teachers teaching core subjects in the basic education program.

In student-teachers' education, it is fundamental to foster the intercultural communicative competence for them to express their views on cultural concepts and phenomena in written and orally, with native and non-native speakers of a foreign language. In the same vein, future foreign language teachers, particularly at an early stage of their learning process, are expected to possess some basic citizen competencies which allow them, amongst other things, to show an understanding of the country they live in, the cultural diversity it has, and the current situation they and their co-nationals are facing (cognitive dimension). Bering in mind the importance of competences mentioned before. This short-scale quantitative study set out to classify the perceptions that a group of student-teachers had on Colombia, their cultural identity, and Colombians' cultural identity in general. To that end, one oral and two written short narratives along with a final questionnaire were collected and analysed using Atlas TI. 8 and Excel spreadsheets. The counting and classification of prominent speech parts that conveyed perceptions (nouns, nouns plus adjectives and adjective per se) unveiled that participants held quite optimistic views on their nation, particularly in cultural, natural, geographic, and culinary aspects. It was also revealed that student-teachers had a high appreciation of themselves culturally speaking, praising their personality and mood as most important features. Furthermore, it was unveiled that participants held a positive view about their compatriots, highlighting their personality, mood, and character. It is important to remark that positive views about own identity were much higher than general views on Colombians.

The instrument that assesses teachers' competence on AR methodology is limited. Thus, it is one of the issues concerning evaluating the effectiveness of a professional development program on designing AR projects. It is difficult to determine how much and what teachers have learned in a course or training. Thus, this cross-sectional study aimed to evaluate further the validity and reliability of the Teacher's Competence in Action Research Questionnaire, a seven-factor instrument previously proposed by Cortes, Pineda, and Geverola (2020). This self-report scale was not subjected to confirmatory factor analysis, had less sample size, and had homogenous participants. In the present study, 450 participants, both pre- and in-service teachers and from different teaching specializations, answered the survey. The data were analyzed using the confirmatory factor analysis method through the Maximum Likelihood approach. Four model fit indices recorded satisfactory results (CFI = 0.890; TLI = 0.884; RMSEA = 0.072; SRMR = 0.039), thus, supporting the seven-factor scale. The standardized factor loading, composite reliability, average variance extracted, and Cronbach's alpha coefficient/s of the entire scale and within subscales also provide evidence of the convergent validity and reliability of the scale. There may be an issue in the discriminant validity of the scale, but the conceptual distinctions of each factor as supported by theoretical foundation and arguments provide a principal reason for retaining all the items and factors.

The rapid growth of the U.S. Latinx population has led to an increased need for community organizations and academic institutions to develop partnerships focused on addressing gaps in health maintenance and education of Latinx individuals. Medical schools also have a responsibility to educate future physicians in delivering culturally sensitive care through community-oriented learning experiences. This case study approach outlines the logistics of establishing a youth mentoring program between a medical school and a Latinx community and demonstrates the benefits to the institution, medical students, and the population served. We also discuss the challenges arising from this partnership and present early program evaluation data showing consistent mentor satisfaction reported over time. This description of the program development provides a framework for creating similar initiatives in medical education to address known disparities in health and well-being of Latinx individuals and other minority populations.

This research emerged from the need to understand educators' working and teaching conditions during the initial period of distance teaching implementation brought about by the need to continue education in the face of the public health emergency and the suspension of on-site classes in Chilean schools. Thus, the aim of this investigation is to explore Chilean teachers' perceptions in relation to Emergency Remote Teaching (ERT) within the COVID-19 context. The methodology includes a dynamic online questionnaire to allow a large number of educators to be included in the study. Some of the findings include the substantial curricular adaptation made by teachers, the use of teachers' own resources to contact students, the overall low level of satisfaction with remote teaching, as well as the increased working hours, and the different connectivity conditions and levels of student participation depending on the socio-economic profile of the school. The conclusions of this research are discussed from the perspective of the hypotheses presented in this study.

The relevance of Open Educational Resources (OER) in the Latin American university context requires an instrument that measures the conceptual, procedural, and attitudinal aspects that teachers consider having in their open educational practices. The purpose of this research is to describe the process of design and validation of the Attitudinal Scale of Open Educational Practices (ASOEP) Scale. Consequently, the methodological approach corresponds to a descriptive, transectional, instrumental design that has three components: scale design, evaluation by expert judgment and validation with the pilot application. The pilot test was applied to a random sample with 123 teachers at a university in Colombia. The results from the validation of the content had the participation of five international experts who were classified according to coefficient K in the range between (k: .80 and k: 1.00). From the pilot application, the ASOEP Scale presented a general reliability of ([alpha]: 0.943).

This report shows the impact that a two-year, coaching based, job-embedded administrator credentialing program is having on the leadership development of new administrators. The Clear Administrative Services Credential (CASC) program is centered on a conceptual framework founded on six professional learning standards combined with real life professional learning contexts, coaching conversations, professional development, and reflection. CASC participants have reported a high level of satisfaction and leadership development as a result of their inclusion in the program. CASC is provided at no charge to participants demonstrating their district's commitment to investing in and growing their own future leaders.

This article presents the results of a study that gave a voice to 119 faculty members of 10 Spanish universities, who were recommended by their students with disabilities for carrying out an inclusive pedagogy. Following a qualitative methodology, two interviews were held to analyse different areas of inclusive pedagogy: beliefs, knowledge, designs and actions. The data were analysed through an inductive system of categories and codes. The results show the positive aspects and benefits highlighted by these faculty about their experiences regarding the presence of students with disabilities in their classrooms, as well as the main challenges they encounter when attempting to achieve the social and educational inclusion of these students.

This study investigates perception and production of the Catalan mid-vowel /e/-/[epsilon]/ contrast by two groups of 4.5-year-old Catalan-Spanish bilingual children, differing in language dominance. Perception was assessed with an XAB discrimination task involving familiar words and non-words. Production accuracy was measured using a familiar-word elicitation task. Overall, Catalan-dominant bilingual children outperformed Spanish-dominant bilinguals, the latter showing high variability in production accuracy, while being slightly above chance level in perception. No correlation between perception and production performance could be established in this group. The effect of language dominance alone could not explain the Spanish-dominant participants' performance, but quality of Catalan input (native vs. accented speech) was identified as an important factor behind familiar-word production and the inaccurate representation of the target contrast in the lexicon of the bilinguals' less-dominant language. More fine-grained measurements of experience-related factors are needed for a full understanding of the acquisition of challenging contrasts in bilingual contexts.

We investigated characteristics of school-based mental health screening using multiple-gating (MG) approaches through a systematic review of the literature and proportional meta-analyses of screening participation and risk identification. The main analyses included 38 studies conducted in the United States. Pooled estimates indicate that approximately 72% of eligible students participated in initial screening, with 82% of eligible students participating in a second assessment. Approximately 24% of students participating in initial screening were identified as at-risk for mental health difficulties, with 65% identified at-risk in a second assessment. Participation rate was significantly associated with the type of consent process used, with participation rates of 55% and 58% in initial screening and a second assessment, respectively, for studies with active consent processes, and participation rates of 90% and 96% in initial screening and a second assessment, respectively, for studies with passive consent processes. Implications for future research and practice are provided.

Creativity often requires envisioning novel connections and combinations among elements in space, e.g., to invent a new product or generate a work of art. A relationship between spatial cognition and creativity has been demonstrated at both the behavioral and neural levels, but the exact neurocognitive mechanisms that bridge this connection remain unclear. The present study tested whether individual differences in functional activation in spatial cognition-implicated brain regions (specifically focusing on premotor and superior parietal cortex) during mental rotation were associated with figural creativity in a composite object creation task. Functional activation in premotor and superior parietal cortex during a classical spatial task (mental rotation; MRT) has previously been causally linked with dissociable components of spatial cognition: superior parietal activity with abstract spatial representation, and premotor activity with active spatial manipulation. The present findings indicate that individual differences in functional activation of both superior parietal cortex and premotor cortex during MRT were associated with individual differences in figural creativity. The present data thus provide new evidence of a correlation between the activity in spatial cognition-implicated brain regions and figural creativity, and suggest initial insights into particular components of spatial processing (both representation and manipulation) that may be related to creative ability.

In this study, we identify tensions that arise between blackness and Latinidad as AfroLatinx students negotiate identity and belonging on campus. Furthermore, we explore the unique cultural and historical contexts of Latinidad and their connection to what we term "anti-AfroLatinidad" -- beliefs, practices, and behaviors that communicate a deliberate rejection of AfroLatinidad that manifest in personal relationships and are upheld by society at large. Findings include AfroLatinx students actively reject negative orientations about blackness and finding empowerment through their AfroLatinidad. Two major findings emerged: Rejecting black: Experiences with "Anti-AfroLatinidad" and Rejecting Back: Asserting AfroLatinidad.

With the declining number of students interested in pursuing STEM courses such as Bachelor's Degree in Biology as evidenced by low enrollment, HEIs currently offering and those which intend to offer the academic degree program are competing and looking for ways to increase their competitiveness. Hence, several efforts have been made in response to it, including investigating what attracts students to choose the HEI and the course it offers. In this regard, this study aims to evaluate the factors influencing students' intention to enroll Bachelor of Science (BS) in Biology at Cebu Technological University using an extended Chapman's Model of Student College Choice. Using a quantitative cross-sectional survey design, 416 senior high-school students from Cebu Province in the Philippines participated in an online survey. The survey aimed to test the influence of student characteristics, influence of significant people, marketing factor, fixed university characteristics, university image, perceived program quality, and perceived career opportunities on students' intention to enroll in BS Biology. The findings of structural equation modelling suggest that only student characteristics influences students' intention to enroll the academic degree program. Irrespective of the disassociation of six other proposed hypotheses, the offering of the course is still deemed feasible as supported by students' responses in their intention to enroll it. In conclusion, this study reveals the model's usefulness in understanding one of the factors influencing students' intention to enroll in the course. Consequently, the results offer managerial and theoretical implications to further strategize institutional student recruitment techniques.

In this chapter, we examine how spatial access, the extent to which individuals must traverse space or time to reach a community college, varies by time of day across socio-demographic groups. We specifically measure spatial access as the time required to travel to a community college by public transit, a common mode of transportation for many urban residents. Our findings revealed substantive variation in travel times between socio-demographic groups suggesting varying levels of spatial access. They also highlight how public transit infrastructure, residential patterns, and community college locations interact to influence how long students must travel to access postsecondary opportunities.

Teacher content knowledge has been identified as a key prerequisite to effective instruction, and current educational policies require measurement of teacher content knowledge to assess candidacy for licensure. The primary instruments used in the United States are the Praxis Subject Assessment exams, which are designed to measure the subject-specific content knowledge needed to be a teacher. The Praxis Biology Subject Assessment exam, used by 42 U.S. states in the past decade, is the most common national measure used to determine biology content knowledge for teacher certification. Demographic and performance data from examinees (N = 43,798) who took the Praxis Biology Subject Assessment from 2006 to 2015 were compared to present a much-needed picture of who is seeking certification to teach biology, how different groups of aspiring biology teachers have performed, and how demographic makeup of prospective biology teachers compares with reports in previous studies describing the composition of the biology teacher workforce. Results indicate the majority of students self-reported as White (76%), female (66%), having undergraduate grade point averages (GPAs) at or above a 3.0 (76%) and majoring in biology (45%). Additionally, the demographic data were included in a linear regression model to determine the factors that explained the most variance in performance of the examinee. The model revealed substantial differences in average performance and pass rates between examinees of different genders, races, undergraduate majors, undergraduate GPAs, and census regions. This suggests that if the examinee is a White science, technology, engineering, and mathematics major, man with a 3.5 or higher undergraduate GPA, resides in the western United States, or plans to teach in a suburban school, the examinee will on average outperform their counterparts on the exam. From our analyses, we suggest several measures for the improvement of the biology teaching workforce and establish potential issues in the teacher pipeline that may impact the quality and diversity of U.S. biology teachers.

The study of prototype learning activity has received significant attention to elevating students' academic performance. This study utilized the prototype learning design as a significant predictor of students' performance and the like. In addition, this study aimed to explore teachers' strategies for measuring students' creative growth utilizing authentic assessments. Moreover, this study used a survey to assess the perception of the students and teachers. The study used the quantitative inferential which provides the relationship between the two variables' effectiveness and perception of the prototype learning activities. The main instrument used to ascertain these parameters are the two survey questionnaires was researcher-made align with the Department of Education Science competency, the reliability and consistency were validated by the statistician. Results revealed that students' performance was at a high level when engaged in the prototype learning activity. Furthermore, the perception of the students and teachers in terms of ease of use, relevance, and comprehensibility indicates positive perception in relation to the student's performance. Finally, the prototype-based learning approach shows a promising effect on the performance of the student's and teachers' perceptions. Hence, enhancement training in developing a teacher's capacity to design meaningful learning that caters students' needs should be provided.

Extensive evidence and theory suggest that the development of motor skills during infancy and early childhood initiates a "developmental cascade" for cognitive abilities, such as reading and math. Motor skills are closely connected with the development of spatial cognition, an ability that supports deductive reasoning. Despite the linkage between motor skills and spatial cognition, and spatial cognition with deductive reasoning, no research has explored the developmental connection between early motor skills and reasoning ability, a plausible pathway through which the developmental cascade operates. Drawing data from the 1970 British Cohort Study (N = 1,233; 95% British, 5% other race/ethnicity; 54% male, 46% female; 7% low income, 80% middle income, 12% high income), this study investigated whether there was a relationship between gross and fine motor skills in infancy (22 months of age) and early childhood (42 months of age) and visuospatial deductive reasoning in adolescence (at 10 and 16 years of age). Results indicated that fine but not gross motor skills during early childhood positively predicted reasoning in adolescence. Critically, the fine motor-reasoning association mediated the previously observed link between early fine motor skills and adolescent reading and math ability. These results deepen our understanding of developmental cascade theory and mental model theory by identifying visuospatial reasoning (i.e., mental modeling) as a potential mechanism through which motor skills initiate cognitive development and academic success in reading and math. These findings also highlight the importance of early intervention programs targeting motor skills and illuminate the impact of those interventions on later cognitive and academic skills.

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it difficult to draw conclusions about HSs' knowledge of mood distinctions. This study intends to fill this gap by examining Spanish HSs' (n = 76) and Spanish-dominant controls' (n = 25) interpretation and use of an early acquired mood alternation, where the presence of indicative or subjunctive conveys the report of an assertion or a command. Results from two experimental tasks reveal that, even though HSs' performance tends to differ from that of controls'--especially at lower levels of proficiency--the nature and extent of their divergences suggests the need to embrace a more nuanced analysis of HSs' linguistic outcomes when examining modal contrasts.

Previous research indicates that heritage speakers (HSs) of Spanish produce both subjunctive and indicative mood in expected subjunctive contexts. The present study sheds new light on this pattern by testing the effects of morphological regularity on HSs' mood production in volitional contexts, where Spanish-dominant speakers (e.g., first-generation immigrants) use almost exclusively subjunctive forms. Results of an elicited production task, completed by 42 HSs and 10 first-generation controls, reveal that HSs differentiate between the two moods. Despite this sensitivity, HSs also exhibit variability, which is strongly conditioned by regularity. Whereas HSs produce subjunctive forms almost categorically with irregular verbs, their subjunctive production with regular verbs is more variable, a pattern we link to irregular verbs' higher relative lexical autonomy and perceptual salience. Instead of classifying HSs' morphological knowledge in binary terms, we argue for the importance of exploring how variability with mood is shaped by the morphological characteristics of individual lexical items.

In 2015, the Colombian Ministry of Education introduced the Cátedra de Paz (CdP), a national policy that seeks to contribute to human rights, citizenship, violence prevention, and peaceful conflict resolution. In the context of a decentralized education system, schools have significant autonomy to adapt the policy to local contexts. Relatively little research to date has documented the enactment, evaluation, or impact of the CdP. This study aims to understand how educators have interpreted this national mandate, and the extent to which the policy has prompted and expanded teaching and learning opportunities about conflict, peace, and justice. We explore the perspectives of 46 teachers working in public schools across 19 of Bogotá's 20 localities, several years into the creation of the CdP and in the midst of a contentious national peace process. The paper shows a range of enactment formats and uneven impact on teachers' existing commitments to peace education. We conclude that the CdP has had a contradictory effect on school-based practices, legitimizing the importance of peace education as a national imperative, while marginalizing efforts within schools as individualized and bound to the social sciences subject.

The present investigation examines intra-speaker variability in heritage speakers (HSs) of Spanish by focusing on the potential effects of two variables in their acquisition of mood: lexical frequency and morphological regularity. To do so, this study tested participants' interpretation and use of early-acquired mood alternations conveying either assertive or jussive meanings. Results from a truth-value judgment and a picture-based sentence completion task revealed that HSs' performance was significantly modulated by the lexical frequency of the matrix verb introducing the modal alternation, as well as by the regularity of the embedded verbal form. In particular, frequent matrix verbs and irregular forms yielded higher rates of accuracy across most of the experimental tasks, suggesting that the degree of variability in HSs' outcomes is determined, to a certain extent, by these two factors. These results favor an account of heritage language acquisition and loss focused on the effects of lexical activation on bilinguals' grammatical representations (Perez-Cortes, Putnam and Sánchez, 2019; Putnam and Sánchez, 2013).

The COVID-19 pandemic has widely affected existing academia-sponsored community service initiatives. Little is known about the strategies to sustain these initiatives during a public health crisis and the potential effects on community well-being and education. In this case study, we describe the impact of the pandemic on service partnerships between our medical school and the Latinx community, discuss the challenges and opportunities of transitioning to a virtual community service model, and offer solutions and considerations.

Purpose: The purpose of this study was to obtain a more comprehensive understanding of the pathophysiology and impact on daily voice use of nonphonotraumatic vocal hyperfunction (NPVH). Method: An ambulatory voice monitor collected 1 week of data from 36 patients with NPVH and 36 vocally healthy matched controls. A subset of 11 patients with NPVH were monitored after voice therapy. Daily voice use measures included neck-skin acceleration magnitude, fundamental frequency (f[subscript o]), cepstral peak prominence (CPP), and the difference between the first and second harmonic magnitudes (H1-H2). Additional comparisons included 118 patients with phonotraumatic vocal hyperfunction (PVH) and 89 additional vocally healthy controls. Results: The NPVH group, compared to the matched control group, exhibited increased f[subscript o] (Cohen's d = 0.6), reduced CPP (d = -0.9), and less positive H1-H2 skewness (d = -1.1). Classifiers used CPP mean and H1-H2 mode to maximally differentiate the NPVH and matched control groups (area under the receiver operating characteristic curve of 0.78). Classifiers performed well on unseen data: the logit decreased in patients with NPVH after therapy; [greater than or equal to] 85% of the control and PVH groups were identified as "normal" or "not NPVH," respectively. Conclusions: The NPVH group's daily voice use is less periodic (CPP), is higher pitched (f[subscript o]), and has less abrupt vocal fold closure (H1-H2 skew) compared to the matched control group. The combination of CPP mean and H1-H2 mode appears to reflect a pathophysiological continuum in NPVH patients of inefficient phonation with minimal potential for phonotrauma. Further validation of the classification model is needed to better understand potential clinical uses.

Text-message-based parenting programs have proven successful in improving parent engagement and preschoolers' literacy development. This study seeks to identify mechanisms of the overall effect of such programs. It investigates whether actionable advice alone drives previous studies' results and whether additional texts of actionable advice improve program effectiveness. The findings provide evidence that text messaging programs can supply too little or too much information. A single text per week is not as effective at improving parenting practices as a set of three texts that also include information and encouragement, but a set of five texts with additional actionable advice is also not as effective as the three-text approach. The results on children's literacy development depend on the child's pre-intervention literacy skills. For children in the lowest quarter of the pretreatment literacy assessments, providing one example of an activity improves literacy scores by 0.19 standard deviations less than providing three texts. Literacy scores of children in higher quarters are marginally higher with only one tip per week than with three tips per week. We find no positive effects of increasing to five texts per week.

This qualitative study documented the way in which a social studies teacher co-created language space with emergent bilingual youth. Drawing from qualitative approaches, we collected data from a teacher interview (s), classroom observations and student artifacts to chronicle the way in which a secondary social studies teacher enacted translanguaging pedagogy to expand on students' understandings of their own "civicness." We employed a translanguaging theoretical lens to examine the manner in which one teacher taught civic education and present pedagogical practices of teacher translanguaging used intentionally to advance students' language development. Findings from this study suggest that community resources and belonging used within translanguaging pedagogy broaden students' knowledge of their own civic identities, agency, and membership.

This study tested child characteristics (temperamental executive control and negative reactivity) and maternal characteristics (parenting behaviors and maternal depressive symptoms) as predictors of a mother's emotion-related socialization behaviors (ERSBs). Further, parenting behaviors and ERSBs were examined as predictors of children's emotion knowledge, social competence, and adjustment problems. ERSBs and children's emotion knowledge were tested as mediators of the effects of child and parent characteristics on adjustment. A community sample (N = 306) of mothers and children (36-40 months at T1) were assessed 4 times, once every 9 months, and assessments included maternal reports of depressive symptoms, observed temperament, observational ratings of general parenting at T1, maternal report of ERSBs at T1 & T2, behavioral measures of emotion knowledge at T3, and teacher ratings of children's adjustment at T4. There were no predictors of ERSBs above prior levels. Higher executive control and lower maternal depressive symptoms predicted greater child emotion knowledge, highlighting the roles of maternal and child contributors to emotion knowledge. Greater emotion knowledge and positive affective quality in parenting predicted children's adjustment, with emotion knowledge mediating the effects of executive control on children's adjustment. In addition, lower levels of maternal supportive ERSBs predicted greater adjustment problems. This study highlights the roles of key variables in Eisenberg, Cumberland, and Spinrad's (1998) heuristic model of emotion socialization and the importance of emotion socialization and emotion knowledge in children's adjustment.

Williamson ether experiments are commonly performed by students in undergraduate organic chemistry instructional laboratory courses. In this multioutcome experiment, students were provided 4-bromophenol and one of three alkyl halides: 1-bromopentane, 1-bromobutane, or 1-bromo-3-methylbutane. The alkyl halides served as the unknown component of the experiment, and students were given these three as unknown candidates. After isolating the product from the reaction mixture, students analyzed their products using FT-IR and benchtop [superscript 1]H NMR spectroscopies. The experimental results herein summarize the inclusion of this experiment in the large enrollment second-semester organic chemistry laboratory course over four semesters.
