The aim of the research was to examine and evaluate how preservice mathematics teachers’ use of manipulatives to teach mathematics. In the current research, one of the qualitative research methods, case study was used. The research was conducted with 21 preservice mathematics teachers. Ten instructional sessions with manipulatives were carried out...

The aim of this study was to analyse preservice elementary mathematics teachers’ concept definitions of circle, circular region, and sphere concepts in geometrical terms. The research was conducted during the 2016–2017 academic year with 56 preservice mathematics teachers enrolled within a teacher education programme at a state university in Turkey...

This study aims to analyze how the Mathematics Teacher Candidates (MTCs) define the "prism" and "pyramid" concepts in geometry. The research was carried out in 2017-2018 academic year with 92 MTCs. This test consists of 3 open-ended questions that MTCs can answer conceptually. The first open-ended question was as "Define a prism", the second was as...

The purpose of the current study was to investigate the effect of micro-teaching practices with concrete models on the pre-service teachers’ self-efficacy beliefs about using concrete models and to determine the opinions of the pre-service teachers about this issue. In the current study, one of the mixed methods, the convergent design (embedded) wa...

The aim of this study is to examine the predictor and explanatory relationships among eighth-grade students’ affective factors of attitude toward geometry, geometry anxiety, and geometry self-efficacy, as well as the cognitive factor of spatial visualization skills, with geometry achievement. This relational survey study was conducted on 487 eighth...
