The effecct on realistic mathematics education on students' success on 7th grande equality and equations and student opinions

The aim of this study is to examine the effect of RME on student achievement in teaching the subject of equality and equations in the 7th grade algebra learning field and the views of students on RME. In the research, the wedge research model, in which quantitative and qualitative research methods are used together, was used. Quantitative research method was used to examine the effect of RME on students' achievement in 7th grade equations, and qualitative research method was used to examine students' views on RME. The research group consists of 7th grade students of Alparslan Secondary School in the central district of Siirt province in the 2021-2022 academic year. In order to determine the classes to be applied for, the school principal's mathematics grade point averages of the 7th grade students were requested from the previous semester, and the mathematics grade averages of the students were examined on a class basis, and it was seen with the help of the SPSS21 package program that the mathematics grade averages were normally distributed. For this reason, there was no harm in taking the two classes with the closest grade point averages of the students. The researcher applied the lottery method in order to determine the experimental and control groups among the two determined classes. As a result of the draw, 7/A class became the control group, while 7/C class became the experimental group. In order to see whether there is a significant difference between the initial levels and mathematics achievements of the experimental and control groups, the achievement test was applied to both classes as a pretest and it was observed that there was no significant difference between them. While the students in the experimental group were teaching with the activities and materials prepared for RME, the students in the control group taught with the MEB textbook-based teaching. After the completion of the application process, "student opinion and form for RME" was given to the volunteers from the experimental group students. As a result of the quantitative data, it was determined that the achievement of the students in the experimental group increased significantly compared to the success of the students in the control group. As a result of the qualitative data, it was seen that the interests and attitudes of the students towards the mathematics lesson were positively affected, their prejudices were reduced, and they learned by having fun.
