Increasing primary school students’ reasoning ability on the topic of plane geometry by using hawgent dynamic mathematics software

Abstract Plane geometry is one of the topics taught in middle school that is difficult to understand. Mostly, teachers use the traditional teaching method when explaining this concept which is why most students only memorize the formula for plane geometry without knowing how the formula is formed. These factors affect students’ reasoning ability. According to the information above, there are two main purposes of this research. The first purpose is to know how significant is the effect of Hawgent dynamic mathematics software on primary school students’ reasoning ability and the second purpose is to compare primary school students’ reasoning ability between the experimental and controlled classes. The sample of this research is 30 5th grade students in one of the primary schools in Cimahi city, Indonesia in the year of 2019/2020. The data collection will be done by using the pre-test and post-test to compare the primary school students’ reasoning ability in the experimental and controlled class. The data will be processed by using SPPS 16 and Microsoft excel. The result of this research is that there is an effect in students’ reasoning when using Hawgent dynamic mathematics software as a learning media and comparing the reasoning ability of the controlled and experimental class on the topic of plane geometry.
