The Effect of the Group Investigation Model by Geogebra-Assisted on Student Learning Outcomes in Elementary Algebra Courses

Abstract

This research was conducted with the aim of finding out the effect of the Group Investigation learning model with Geogebra tools on the learning outcomes of elementary algebra students in the Bachelor of Mathematics Education study program at Bengkulu University. The type of research carried out was quasi experimental research with a pre-test post-test control group design. The research sample was students from the Bachelor of Mathematics Education study program at Bengkulu University, semester 1A with a total of 29 students and semester 1B with a total of 29 students. Semester 1A students applied the Group Investigation model assisted by Geogebra and semester 1B students applied the conventional method. The data was analyzed statistically descriptively and inferentially using t-test and obtained a value of p-value or sig<0.05, namely 0.00<0.05, so it can be concluded that the use of the Group Investigation learning model assisted by Geogebra has affected student learning outcomes. Bengkulu University's Bachelor of Mathematics Education study program is effectively applied to elementary algebra learning in class and has an effect in improving student learning outcomes.
