This study was conducted to examine the effectiveness of proof tasks in the transition from conjecture to proof in Euclidean geometry on freshmen's proof schemes. In line with this aim, the proof schemes of the freshmen who performed conjecture-proof and theorem-proof tasks were compared. The freshmen were composed of 109 pre-service middle school…

The present study aims to examine the preservice middle school mathematics teachers' ability to perform the process of mathematizing and to identify their competencies within this context. For this purpose, the study was conducted with 43 preservice teachers attending a state university. The research method used is descriptive research. As the…

As students transition from elementary to middle school, they often perform at a reduced academic level than their elementary school academic performances. Middle school is the time when students experience changes developmentally, emotionally, physically, and socially. Students will experience personal and academic problems if the school or…

This study investigated preservice middle school mathematics teachers' (PSTs) understanding of proportional and nonproportional relationships and their abilities to differentiate these relationships from each other. The PSTs' abilities to interpret and represent proportional and nonproportional situations and solution strategies were also…

The design of the flipped classroom (FC) as a pedagogical approach is becoming increasingly prevalent in mathematics education. However, although many studies have been conducted on whether FCs are more effective in improving mathematics achievement compared to traditional lectures, the results are not consistent. To address this issue, this…

Purpose: Grounded in self-determination theory, this study examined factors of secondary early field experiences that preservice teachers consider significant and how these experiences impact them as educators. Method: Preservice teachers (N = 13) completed two 10-week early field experiences, one at each level--middle school and high school. Data…

Integrating computational thinking (CT) into various disciplines via computer science (CS) methods such as unplugged, block-based, text-based, and physical programming is a trending topic in educational sciences. This study presents a perspective on implementing an unplugged computer science activity to integrate CT into mathematics education.…

Purpose: The purpose of this study was to explore middle and secondary mathematics preservice teachers' (PST) perceptions of the benefits, challenges and impacts of implementing lesson study. Design/methodology/approach: This paper presents a single case study in the university context. Embedded units of analysis included a group of middle and a…

The dual pandemics of social unrest and COVID-19 during the summer of 2020 in the United States has produced a renewed sense of urgency and agency for the interrogation of curriculum in K-12 education and the development of culturally sustaining practices. This urgency has encouraged more teacher preparation programs and middle school leaders to…

Knowing how best to respond to students' mathematical inquiries is an important skill for all teachers to develop. A class of pre-service teachers (PSTs) was presented with a scripting task in which a student conjectured that 1/6.5 was "exactly in between" fractions 1/6 and 1/7. However, instead of addressing the student's inquiry…

This study was aimed to reveal what types of questions were asked by pre- service teachers and what kind of interactions they established with the 5th-8th grade students. The extent to which the questions the pre-service teachers asked are related to the interactions they established with the students was also investigated. Case study, one of the…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

This study explores how seven middle and secondary teachers understood and developed ambitious pedagogies within the context of their own classroom. Although there has been an emphasis on preparing preservice teachers for utilizing ambitious pedagogies, these practices are often not observed in practicing teachers' classrooms. The purpose of this…

Analysis of multiple forms of data from a high-need K--8 charter school led to the hypothesis that increasing disciplinary disruptions and poor student academic achievement were the results of endemic student trauma. The principal, the lead school counselor, and an advisory council created a plan to explore and address behavioral and…

Purpose: To explore undergraduate students' experiences leading and facilitating an out-of-school-time (OST) physical activity program for middle school girls. Method: Five female undergraduate students (N = 4 Black or African American) participated in semistructured individual interviews and submitted weekly reflections during their time leading…
