    Comparison and evaluation of augmented reality technologies for designing interactive materials
    (Springer, 2023) Sat, Mustafa; Ilhan, Fatih; Yukselturk, Erman
    Although there has been a growing interest in the use and adoption of augmented reality (AR) technology in educational institutions recently, there is limited research dwelling on pre-service teachers' technical and pedagogical preparation for AR technology. This study investigated teacher candidates' perceptions concerning their learning and immersive experiences of different AR tools and compared these tools on seven dimensions, i.e., intention to use, multimedia, satisfaction, usefulness, self-efficacy, effectiveness, and system quality. A mixed method approach was adopted to analyze qualitative and quantitative data gathered from 55 pre-service teachers who attended a five-day online seminar program about AR tools. The findings showed that teachers developed positive views for all AR tools but some tools like CoSpaces, Fectar, and Blippar were found to be significantly superior in all dimensions to Wikitude, UniteAR, and Unity & Vuforia. The findings also revealed that AR tools presented both affordances and challenges for instructional learning environments. While affordances included materializing and visualizing the abstract concepts, providing permanent learning, and catching interest, challenges consisted of unaffordable applications, limited educational content, internet connectivity issues, and limited access to devices. Overall, the findings of the current study have offered significant implications for designing and preparing AR-enhanced interactive course materials.

    Empowering teachers' professional development with e-textiles supported educational STEAM projects
    (Springer, 2024) Sat, Mustafa; Cagiltay, Kursat
    The study aimed to investigate the dynamics of e-textile-supported STEAM activities, specifically focusing on the design and development process of e-textile projects. A professional development (PD) program with seven hands-on and design-based activities was developed and implemented in two camps involving 20 and 19 in-service science teachers. Design-based research was adopted, and interviews were triangulated with multiple forms of data from observations, camp evaluation forms, surveys, and design artifacts. Results indicated that the hands-on activities incorporate key design components with pros and cons, offering engaging, interactive, and collaborative learning experiences for science teachers. However, they involve significant challenges in coding, aesthetics, circuitry, sewing, design sketching, and materials. The study also offers ten design principles for individuals to make informed decisions about the design and development of STEAM projects using e-textile technology. This study has significant implications for educational designers who consider designing e-textile-supported STEAM activities for K-12 teachers/students and for teachers who are interested in integrating these activities into their science courses.

    K-12 TEACHERS' PERCEIVED EXPERIENCES WITH DISTANCE EDUCATION DURING THE COVID-19 PANDEMIC: A META-SYNTHESIS STUDY
    (Anadolu Univ, 2024) Kadirhan, Zafer; Sat, Mustafa
    A sudden shift to distance education during the COVID-19 pandemic inTurkiye strained teaching and learning activities, placing K-12 teachers in a novel context with challenges and opportunities to investigate. This study explores the teaching experiences and opinions of K-12 teachers during the COVID-19 pandemic, focusing on challenges, advantages, and suggestions. Search queries were executed in leading databases (DergiPark, ULAKBIM TRDizin) to locate potential studies. Twenty-two studies meeting the predetermined inclusion and exclusion criteria were subjected to a rigorous and iterative thematic analysis using the qualitative meta- synthesis approach. The results revealed significant challenges categorized into ten themes: shortcomings in technology and infrastructure, student motivation and engagement, technology literacy, and social and emotional well-being. The results also highlighted key advantages of distance education in eight categories such as learning improvement, flexibility and convenience, and digital tools and resources. Additionally, the study identified valuable suggestions that contribute to the success of distance education, such as adapting curriculum, increasing access to technology, strengthening internet infrastructure, providing teacher training and support, developing engaging and interactive instructional materials, and improving communication and collaboration between students and teachers. The study results inform the development of evidence- based practices and policies that can support K-12 teachers in providing quality online education during times of crisis.

    Unveiling competence in the classroom: A multidimensional assessment of computer science teachers' self-efficacy in coding education
    (Springer, 2024) Sat, Mustafa; Kadirhan, Zafer
    The significance of teachers' self-efficacy in coding education within K-12 settings has grown substantially. However, the literature lacks subject-specific measurement tools tailored to assess teachers' self-efficacy in coding instruction. This study adopted a mixed methods approach to develop a reliable and valid instrument for measuring computer science (CS) teachers' self-efficacy in teaching coding. The scale development involved a rigorous process encompassing item generation, expert validation, and pilot testing. Importantly, this process unfolded in seven steps with two distinct phases, and each phase involved independent sample groups. Subsequently, a comprehensive survey was administered to two samples of CS teachers (n = 318, n = 295) to assess the scale's psychometric properties. The results revealed robust internal consistency and construct validity of the 20-item Coding Teaching Self-Efficacy Scale (CTSES) with four intercorrelated dimensions: student motivation, subject knowledge, classroom management, and material development. Furthermore, additional analyses revealed the significant impact of teaching experience and self-reported coding knowledge level on teachers' self-efficacy in teaching coding. The implications of this study hold significance for both practitioners and researchers to understand teachers' self-efficacy in teaching coding and to explore its relation to teacher training, curriculum development, and the broader advancement of coding education within school settings.
