This study investigated the effect of a paper folding activity prepared to develop the sixth-grade students' concept definitions and images of parallelism and perpendicularity concepts. The study also examined how the concept definition and images changed after the paper folding activity. A combination of quantitative and qualitative methods was…

This study explores the sophomore year, a critical juncture during the undergraduate experience with notable attrition rates. By dissecting environmental, academic, and situational determinants, this study provides insightful perspective by delving into the student narrative, enriching the existing literature. Employing semi-structured interviews,…

The aim of this longitudinal research is to examine the development process of scientific and consistent knowledge structures of first, second, and third-grade students in middle school within the concepts of melting and dissolution according to conceptual change theories at the end of the education and training processes carried out in…

We have investigated the temporal patterns of algebra (N = 606) and calculus (N = 507) introductory physics students practicing multiple basic physics topics several times throughout the semester using an online mastery homework application called science, technology, engineering, and mathematics (STEM) fluency aimed at improving basic physics…

The aim of the study was to investigate the effect of the Common Knowledge Construction Model (CKCM) on 10th-grade students' conceptual understanding of the buoyancy and density of liquids topic. Within a pre-experimental (one group pre-test/post-test) research design, this study was conducted with 22 of 10th-grade students. To collect data, the…

Despite the recognition of the importance of teachers' professional development, the exploration of teachers' Critical Incidents (CIs) as a type of professional development initiative has received insufficient attention in L2 teaching contexts. Motivated by the dearth of research in this area and building on complexity theory as its conceptual…
