Article Citation - WoS: 1Citation - Scopus: 1Technology-Enhanced "gipsci" Approach in Developing Contexts Performs Well at Interest and Curiosity, Yet, Needs Reinforcing at Inquiry Level(Routledge Journals, Taylor & Francis Ltd, 2025) Birgili, Bengi; Bulut, Mehmet Akin; Gulunay, Oksana; Kocoglu, Merve; Bas, Fatma RuveydaNumerous studies explore inquiry in science centers, but technology-enhanced science centers' (TeSC) curricula remain relatively nascent. This mixed-methods study explores how the GiPSci model, a technology-enhanced science center program developed in-house by curriculum experts, supports learners' inquiry skills aligned with international standards. Data were collected through learners' products (n = 161), lesson observations (n = 20), train-the-trainer activities (n = 405), expert evaluations (n = 14), and interviews with trainers (n = 10). Findings reveal curiosity and interest scored higher than inquiry, highlighting the challenges of inquiry in tech-enhanced settings. Consensus among trainers, observations, and learners' products points to gaps in fostering inquiry skills in the TeSC program. To enhance GiPSci-like models, collaboration among program designers, trainers, and train-the-trainer providers is essential to better align the technology-enhanced science centers' program with inquiry-based learning.Conference Object Citation - Scopus: 1Technology Use: Analysis of Lesson Plans on Fractions in an Online Laboratory School(PME, 2022) Pekkan, Zelha Tunç; Ünal, Gizem...Conference Object Unconventional Thinking in Online Laboratory School: Fractions(PME, 2022) Kayıtmaz, Özlem; Pekkan, Zelha Tunç; Tunç-Pekkan, Zelha...Book Part How the Cephei E-Course Syllabus Design Was Developed and Implemented(Springer International Publishing, 2022) Kurban, Fell Caroline; Kurban, Caroline FellWhile the digitalization of education has been around since the 1990s, it is only since the Covid-19 pandemic that it has really taken hold in education, when universities were forced to rapidly move online and traditional patterns of teaching were no longer viable. This pushed universities to provide a blended learning environment drawing on technologies that our students, as digital natives, had already been using on a daily basis for some time. However, blended learning is only effective if underpinned by tried and tested learning frameworks—something that many universities were not prepared for when the shift to online learning took place. The Cooperative e-learning Platform for Industrial Innovation (CEPHEI) however, was already prepared and ready for this shift, as from 2017 it had been working on the development of an e-learning platform with the aim of digitizing education while also integrating the reality of professional innovation activities into the context of education according to the demands of industry. To achieve this aim, one of the first phases of the project was to identify key learning frameworks for e-course syllabus design, based on existing research, that could be used to provide recommendations for instructors in the development of their CEPHEI courses. This chapter presents the culmination of this process and provides a framework that can be used by instructors or institutions wishing to design e-learning courses. To make these frameworks tangible for the reader, examples are given throughout the chapter from an undergraduate environmental engineering course in a civil engineering department. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.Article Citation - WoS: 1Citation - Scopus: 2The Mediating Role of Instructional Design and Video Length Between Grade Level and Pupil-Content Interaction in Instructional Mathematics Videos on Youtube(Springer, 2024) Demir, Ömer; Birgili, BengiThe use of instructional videos is rampant in education; however, their interaction is limited by weak instructional design. Gagne has never insisted on using his renowned 9 Events of Instruction slavishly in situations as a viable paradigm for utilization in video design. Connecting grade level, video length, and interaction, this study seeks to determine the relevance of Gagne's prescribed 9 event sequence in instructional mathematics videos. We scrutinized 50 instructional mathematics videos on YouTube geared towards middle school pupils ranging between 5th and 8th grades. We used quantitative media content analysis for video analysis. In data analysis, partial least squares were used. Bayesian estimation was also resorted to for cross checking. The data revealed that one-third of Gagne's instructional design steps were not always present: activating prior knowledge, eliciting performance, and finally providing feedback. A mediation analysis between grade level and video length revealed that 6 events fully mediated the association between the two. We also elicited the impact of these variables on affective and behavioral interactions in videos. This study assists in creating an idiosyncratic instructional design model, called Birgili's 8 steps for instructional video design, and in infusing this with a melange of four theories. In contrast with the status quo attesting that the literature abounds with scholarly works touting the shorter is the better mantra, the results substantiated that longer may be better in leveraging video interactions provided that the length is judiciously used to conform to instructional design principles.Article Citation - WoS: 1Citation - Scopus: 1Validating Psychometric Classification of Teachers' Fraction Arithmetic Reasoning(Springer, 2023) Ölmez, İbrahim Burak; Izsak, AndrewIn prior work, we fit the mixture Rasch model to item responses from a fractions survey administered to a nationwide sample of middle grades mathematics teachers in the United States. The mixture Rasch model located teachers on a continuous, unidimensional scale and fit best with 3 latent classes. We used item response data to generate initial interpretations of the reasoning characteristic of each latent class. Our results suggested increasing facility reasoning about fraction arithmetic from one class to the next. The present study contributes two further arguments for the validity of our initial interpretations. First, we administered the same survey to a new sample of future middle grades mathematics teachers before and after 20 weeks of instruction on multiplication, division, and fractions, and we found that from pretest to posttest future teachers transitioned from one latent class to another in ways consistent with increased proficiency in fraction arithmetic. Second, we interviewed 8 of the future teachers before and after the instruction and found that future teachers' reasoning during interviews was largely consistent with our original interpretation of the 3 latent classes. These results provide further support for our original interpretation of the mixture Rasch analysis, demonstrate the utility of our approach for capturing growth and change in future teachers' reasoning during teacher education coursework, and contribute innovative applications of psychometric models for surveying teachers' reasoning at scale.Article Citation - WoS: 3Citation - Scopus: 2A New Learning Community for Educating Future Teachers: Online Baboratory School(Taylor and Francis Ltd., 2022) Pekkan, Tunç Zelha; Taylan, Didem Rukiye; Tunc-Pekkan, Zelha; Taylan, Rukiye DidemTo provide quality mathematics education for disadvantaged groups of middle school students and continue to offer quality practicum experience to future teachers during the Covid 19 outbreak, we founded the Online Laboratory School. This school was free and open to public school students: 130 middle school students throughout Turkey attended for a 5-week period. There were 25 pre-service teachers actively involved in teaching, under the close supervision of 7 university supervisors. The entire gamut of planning, teaching and reflection sessions for each virtual class were recorded via an e-learning platform. Additionally, survey data was collected from the participating students, parents, pre-service teachers and supervisors. Our findings indicate that we were able to build a unique and virtual learning community. While pre-service teachers and middle school students benefited the most, university supervisors also reported improving their skills on when and how to give feedback. We describe how the school functioned and the range of opportunities it provided to all participants considering situated-learning perspectives and building online-learning communities. We also discuss how this model can be used in the future as a strong asset for teacher education programs and adaptation of fieldwork practices.Article Citation - Scopus: 5Predicting Undergraduate Students' Mathematical Thinking About Derivative Concept: a Multilevel Analysis of Personal and Institutional Factors(Elsevier BV, 2014) Ubuz, Behiye; Aydın, UtkunThis cross-sectional study examines the determinants of mathematical thinking aspects at two levels: within-classroom level and between-classroom level. We hypothesized that personal factors (gender, socioeconomic status (parents' educational attainment), current cumulative grade point average, prior mathematic achievement (high school mathematics achievement)) and institutional factors (faculty/school affiliation, grade level) have concomitant associations with students' mathematical thinking about the derivative. The sample consisted of 2424 undergraduates from 130 classrooms. Multilevel modeling showed that students' mathematical thinking about the derivative varied primarily as a function of their gender and cumulative grade point average (within-classroom level) and of their faculty affiliation (between-classroom level). Parents' educational attainment and high school mathematics achievement at the within-classroom level, and grade level at the between-classroom level were only moderately associated with different mathematical thinking aspects. Methodological and practical implications of the findings are further discussed. © 2014 Elsevier Inc.Article Citation - WoS: 30Citation - Scopus: 44An Analysis of Elementary School Children's Fractional Knowledge Depicted With Circle, Rectangle, and Number Line Representations(Springer, 2015) Tunç-Pekkan, ZelhaIt is now well known that fractions are difficult concepts to learn as well as to teach. Teachers usually use circular pies, rectangular shapes and number lines on the paper as teaching tools for fraction instruction. This article contributes to the field by investigating how the widely used three external graphical representations (i.e., circle, rectangle, number line) relate to students' fractional knowledge and vice versa. For understanding this situation, a test using three representations with the same fractional knowledge framed within Fractional Scheme Theory was developed. Six-hundred and fifty-six 4th and 5th grade US students took the test. A statistical analysis of six fractional Problem Types, each with three external graphical representations (a total of 18 problems) was conducted. The findings indicate that students showed similar performance in circle and rectangle items that required using part-whole fractional reasoning, but students' performance was significantly lower on the items with number line graphical representation across the Problem Types. In addition, regardless of the representation, their performance was lower on items requiring more advanced fractional thinking compared to part-whole reasoning. Possible reasons are discussed and suggestions for teaching fractions with graphical representations are presented.

Through an innovative method, which allowed for documenting in-the-moment teacher noticing, the author was able to explore teacher noticing and reflective practices in the context of classroom teaching as opposed to professional development environments. Noticing was conceptualized as both attending to different elements of classroom instruction and making sense of classroom events. The teacher paid most attention to student thinking and was able to offer a variety of rich interpretations of student thinking which were presented in an emergent framework. The results also indicated how the teacher’s noticing might influence her instructional decisions. Implications for both research methods in studying noticing and teacher learning and practices are discussed.
