The effects of demonstration method on students' success and permanence in geometry learning area of 6th grade mathematic course

The aim of this study is to investigate the effects of demonstration method in geometry learning area of 6th grade mathematic course. The experimental research, using pre-test and post-test control group design, was conducted with the 6th grade students attending the Cacabey Secondary School in Kırşehir Province in the 2017-2018 academic years. The study was carried out with a total of 65 sixth grade students, 36 in experimental group and 29 in control group.The study groups were selected by the pre-test and the groups included in the study were randomly assigned as experimental and control groups. During four weeks of experimental process, students in experimental group are taught in demonstration method, and students in control groups are taught in traditional method. The experimental group students used the worksheets at the end of the lessons. In this study, achievement test developed by researcher is used as data collection tool. Achievement test is conducted to two study groups as pre-test before experimental process, as post-test after experimental process and as permanency test after three months.In-group and inter-group analysis of the quantitative data collected, dependent and independent sample t tests were analysed with SPSS 17.00 statistical program.According to the results of findings, it is concluded that the method of demonstrating is more effective than traditional method in success and permanency of the student in prisms and measurement unit of geometry learning area.
