The ability to recognize and construct nets is a fundamental aspect of spatial reasoning skills; however, there is a lack of understanding regarding effective instructional sequences for fostering this ability. The aim of this study is to test a Hypothetical Learning Trajectory for enhancing sixth-grade students' understanding of rectangular prism…

It is seen that there are few studies on the role of the knowledgeable other when the literature on Lesson Study [LS] is examined. However, for LS to be better understood and applied in different cultures, the role of the knowledgeable other in LS process should be clarified. This study aimed to determine the role of the researcher as the…

The purpose of the study was to explore the effect of the Montessori Method integrated with cooperative learning on mathematical reasoning skills in the preschool period. In this study, an experimental design with a pretest-posttest control group was used. The study group included a total of 30 children, 15 of whom were in the experimental group…

This study aims to examine the effect of problem posing-based active learning activities on students' problem-posing skills and problem-solving achievement. To this aim, an experimental design with pre-test post-test control group was employed. The participants consisted of two groups of sixth graders, one experimental group (N=23) and one control…

Integrating literacy in science and mathematics learning and teaching has been an ongoing endeavour. There are frameworks developed to guide teachers' practices, but little is reported on assessing literacy simultaneously with scientific or mathematical content knowledge. We reviewed the literature on assessing literacy in science and mathematics…

The aim of this research is to determine the trends of academic articles and postgraduate theses that employ the meta-analysis method in the field of mathematics education and that were published in Turkey between 2011 and 2020. Using the qualitative research method, this research aims to examine with descriptive content analysis the studies…

The aim of this study is to examine the effects of Realistic Mathematics Education (RME) on 7th grade students' achievement on integer operations and their attitudes towards mathematics and to determine students' views about the RME approach. The research was carried out with the participation of 11 students. Exploratory sequential mixed design…

In the world where we always meet geometric constructions, it is a necessity to make sense of the objects belonging to these constructions. In this respect, this study aimed to examine the teaching of volume with the blending of the realistic mathematics education (RME) and GeoGebra. The study group consisted of 12 students attending lessons…

This study aimed to investigate the relative effectiveness of a computer-supported teaching sequence in solving optimization problems in calculus compared to a traditional teaching approach. The participants in the study were 46 first-year prospective mathematics teachers studying in two different classes of a four-year elementary mathematics…

This study aims to elicit the role of formative feedback in the development of students in a mathematical problem-solving process. For this purpose, the study's primary process is to investigate the development of elementary school students (aged 10 to 11) through feedback given during a problem-solving process. While visually engaged in the…

Realistic Mathematics Education (RME) includes identifying and solving problems. Besides, it is an effort to organize a case, reorganize it according to new ideas, and concretize and rediscover the case to understand it better. This research aims to determine the effect of RME-based teaching against traditional methods, develop a general opinion,…

The aim of this study is to examine the effect of activity-based mathematics teaching on the attitudes of elementary school 4th graders towards mathematics activities and their beliefs about mathematics. The research is designed according to the quasi-experimental pretest-posttest control group design. The study group consisted of a total of 50…

The goal of this research is to analyze the Realistic Mathematics Education (RME) studies conducted in Turkey through document analysis and to reveal what a trend is. In the research, 89 studies, including 18 articles, 71 theses, selected with a purposeful sampling method, published between 2002 and 2020, were analyzed. In the selection of the…

The aim of this research study was to examine the opinions and experiences of teachers and pre-service teachers about number sense and its development. The participants of this research were 25 teachers and pre-service teachers studying at undergraduate or graduate level in different regions and different departments of Turkey, who participated in…

This study aims to examine the changes in students' mental constructions of function transformation based on the designed activities, classroom discussions, exercises (ACE) teaching cycle in the light of the action, process, object, schema (APOS) theoretical framework. The study was conducted by seven volunteer students who were enrolled in…
