1. Exploring the Impact of SCOBA Creation on Language Learners' Reading and Reflective Thinking Skills in Concept-Based Reading Curriculum

Author

Ayse Tokaç Kan

Abstract

A new reading curriculum incorporating the principles of concept-based instruction and reading strategy instruction was designed and implemented for a previous study. Concept-based instruction was compared with reading strategy instruction to determine the impact of the new curriculum on language learners' reading and reflective thinking skills. The data revealed that the concept-based group performed better in reflective reading and thinking skills. The new curriculum involves the creation of a Schema of a Complete Orienting Basis of an Action (SCOBA) during reflection sessions. To explore the necessity of SCOBA creation, an experimental study with two groups was conducted, where only one group created a SCOBA. Both groups received concept-based reading instruction and were compared based on their reading, reflective reading, and reflective thinking skills. The data revealed that the groups performed similarly in reading and reflective reading skills, but the SCOBA group performed better in reflective thinking skills. The study sheds light on the importance of incorporating reflective thinking activities, such as SCOBA creation, in concept-based reading instruction.

2. School Adjustment Scale for High School Students: Development and Initial Validation

Author

Semih Kaynak and Adnan Kan

Abstract

Although research has consistently highlighted the importance of school adjustment for high school students, validated tools for assessing this construct are currently lacking. To address this gap, our study aimed to develop and validate a scale to measure school adjustment among high school students. Employing a two-stage approach, we first examined the concept of adjustment and generated scale items. Subsequently, we surveyed 1121 high school students, and randomly split the data into two groups for subsequent analyses. Through exploratory in the first stage and confirmatory factor analyses in the second stage, we identified two higher-order factors within the scale: social adjustment and academic adjustment, with academic adjustment consisting of two sub-factors, academic performance and, academic engagement. The results indicated that the scale has an excellent model fit, as well as adequate reliability and high construct validity. Overall, our study provides a valuable tool for assessing school adjustment in high school students.

3. Checking the Inventory: Illustrating Different Methods for Individual Participant Data Meta-Analytic Structural Equation Modeling

Author

Lennert J. Groot, Kees-Jan Kan, and Suzanne Jak

Abstract

Researchers may have at their disposal the raw data of the studies they wish to meta-analyze. The goal of this study is to identify, illustrate, and compare a range of possible analysis options for researchers to whom raw data are available, wanting to fit a structural equation model (SEM) to these data. This study illustrates techniques that directly analyze the raw data, such as multilevel and multigroup SEM, and techniques based on summary statistics, such as correlation-based meta-analytical structural equation modeling (MASEM), discussing differences in procedures, capabilities, and outcomes. This is done by analyzing a previously published collection of datasets using open source software. A path model reflecting the theory of planned behavior is fitted to these datasets using different techniques involving SEM. Apart from differences in handling of missing data, the ability to include study-level moderators, and conceptualization of heterogeneity, results show differences in parameter estimates and standard errors across methods. Further research is needed to properly formulate guidelines for applied researchers looking to conduct individual participant data MASEM.

Abstract

Microorganisms hosted in abiotic structures have led to engineered living materials that can grow, sense and adapt in ways that mimic biological systems. Although porous structures should favor colonization by microorganisms, they have not yet been exploited as abiotic scaffolds for the development of living materials. Here, we report porous ceramics that are colonized by bacteria to form an engineered living material with self-regulated and genetically programmable carbon capture and gas-sensing functionalities. The carbon capture capability is achieved using wild-type photosynthetic cyanobacteria, whereas the gas-sensing function is generated utilizing genetically engineered E. coli. Hierarchical porous clay is used as ceramic scaffold and evaluated in terms of bacterial growth, water uptake and mechanical properties. Using state-of-the-art chemical analysis techniques, we demonstrate the ability of the living porous ceramics to capture CO2 directly from the air and to metabolically turn minute amounts of a toxic gas into a benign scent detectable by humans.

5. Enhancing University Level English Proficiency with Generative AI: Empirical Insights into Automated Feedback and Learning Outcomes

Author

Sumie Tsz Sum Chan, Noble Po Kan Lo, and Alan Man Him Wong

Abstract

This paper investigates the effects of large language model (LLM) based feedback on the essay writing proficiency of university students in Hong Kong. It focuses on exploring the potential improvements that generative artificial intelligence (AI) can bring to student essay revisions, its effect on student engagement with writing tasks, and the emotions students experience while undergoing the process of revising written work. Utilizing a randomized controlled trial, it draws comparisons between the experiences and performance of 918 language students at a Hong Kong university, some of whom received generated feedback (GPT-3.5-turbo LLM) and some of whom did not. The impact of AI-generated feedback is assessed not only through quantifiable metrics, entailing statistical analysis of the impact of AI feedback on essay grading, but also through subjective indices, student surveys that captured motivational levels and emotional states, as well as thematic analysis of interviews with participating students. The incorporation of AI-generated feedback into the revision process demonstrated significant improvements in the caliber of students' essays. The quantitative data suggests notable effect sizes of statistical significance, while qualitative feedback from students highlights increases in engagement and motivation as well as a mixed emotional experience during revision among those who received AI feedback.

6. Parental Knowledge, Beliefs, Practices, and Barriers Related to Children's Bladder Health in the School Environment

Author

Pranaya Venkatapuram, Juan C. Angulo-Lozano, Stav Spinzi, Cati Brown-Johnson, Ashley Phord-Toy, and Kathleen M. Kan

Abstract

Background: Pediatric lower urinary tract symptoms (LUTS) are a set of common childhood problems. Community-level interventions that target behavioral change among children with LUTS can improve symptoms outside of the clinic environment. Parents, navigating the home and school environments, are key in supporting healthy bladder behaviors. Thus, we asked parents about their perceptions and barriers related to pediatric bladder health. Methods: English-speaking parents (n = 30) of children ages 5-10 years with and without LUTS were interviewed. Transcripts were coded iteratively by two independent coders using deductive and inductive approaches that emphasized consensus coding and peer debriefing. Results: Ninety-three percent of participants were women, 50% were 30-39 years old, and 60% held a graduate degree. Parents identified school-, classroom-, and child-based barriers to bladder health. These included the bathroom environment, restrictive policies for bathroom use, and anxiety on how and when to use the bathroom. Conclusions: Addressing school-, classroom-, and child-based barriers is necessary to promote healthy bladder habits among children in the school environment and beyond. Recommended school-based interventions include bathroom use and sanitation policies that support students' voiding needs, teachers' professional development, and school readiness initiatives. Limitations include participation of English-speaking parents only.

7. Do 3-8 Years Old Children Benefit from Computational Thinking Development? A Meta-Analysis

Author

Xiaowen Wang, Kan Kan Chan, Qianru Li, and Shing On Leung

Abstract

The interest in Computational Thinking (CT) development among young learners increases with the number of studies located in literature. In this study, a meta-analysis was conducted to address two main objectives: (a) the effectiveness of empirical interventions on the development of CT in children aged of 3-8 years; and (b) the variables that influence the effectiveness of the interventions. Following PRISMA procedures, we identified 17 empirical studies with 34 effect sizes and 1665 participants meeting the inclusion criteria from Web of Science database. Overall, we found a statistically significant large effect size (d = 0.83 [95% CI: 730, 0.890]; p < 0.001) on the CT development of 3-8 years old children, which provides empirical support for having young children to engage in CT experiences. The effect size was significantly influenced by moderating variables including gender, scaffolding, and education level. Intervention length showed a marginally significant effect. Therefore, educators could refer to the significant moderators when designing tailored interventions for CT development in early childhood education while a call for more empirical studies of CT development in young children is proposed.
