The effect of geogebra use in teaching the topic of angles on the anxiety, belief and achievement of 6th grade students towards geometry

This research aims to examine the effect of GeoGebra dynamic geometry software on the academic achievement of 6th grade secondary school students about angles, their concerns and beliefs about geometry. The study was carried out in a public school in Alanya district of Antalya province in the 2022-2023 academic year. In the research, experimental and control groups were created, and geometry activities supported by GeoGebra software were applied to the experimental group. In this study, which was conducted using a quasi-experimental design with a pretest-posttest control group, achievement test, geometry anxiety scale and geometry belief scale were used as data collection tools. Students readiness levels, achievement test results, anxiety and belief levels were examined. According to the readiness test results, students in the control group had a higher level of success than the experimental group. According to the results of the achievement test conducted after the study, a significant increase was observed in the success of the students in the experimental group, but this increase was not enough to compensate for the initial high level of success of the control group. Analysis of covariance showed that the achievement test scores of students in the experimental group were significantly different from those of students in the control group, but the effect size of this difference was small. While a significant decrease was observed in the geometry anxiety levels of the students in the experimental group, no significant change was detected in the control group. This shows that GeoGebra software is effective in reducing anxiety. No significant change was observed in the levels of belief in geometry in both the experimental and control groups. This finding shows that dynamic geometry software may be insufficient to transform students' beliefs in the short term. Keywords: GeoGebra, Geometry Anxiety, Belief İn Geometry
