The Relationship Between Secondary School Students' Beliefs and Attitudes Towards Geometry and Their Achievements

In this study, it is aimed to investigate the relationship between the beliefs and attitudes of the secondaryschool students towards geometry and their mathematical achievements. The extent to which the belief and attitudetowards geometry predicts mathematics achievement is another subject. The study was designed with aquantitative method, survey method. Research, located on Turkey's Mediterranean Coast from secondary schoolsin the province chosen by simple random sampling medium sized secondary school in 2019-2020 academic yearstudying 490 (255 boys and girls 235) was carried out by secondary school students. As a data collection tool,“Personal Information Form”, “Geometry Belief Scale” and “Geometry Attitude Scale” were applied to secondaryschool students. Data were analyzed using t-test, ANOVA, Cohen’s f and Cohen’s d effect size values, correlationand multiple regression analysis methods. As a result of the data analysis, a significant positive relationship wasfound between the geometry beliefs and attitudes of secondary school students and mathematics achievement. Inaddition, geometry beliefs and attitudes were found to be significant predictors of mathematics achievement.
