Abstract

The low students’ score of mathematics is influenced by learning that is not insightful to students. Teachers have not implemented learning that has been set for students as suggested by the 2013 curriculum. In addition, teachers have also not utilized technology, especially digital technology in learning. One of the reasons is that teachers have not been able to develop teaching materials for learning models that are set for students and use technology. One of the learning models set for students is the APOS model. To train teachers to compile teaching materials, the implementation of workshop on the development of differential teaching materials using APOS model combined GeoGebra. This workshop was given to SMA/SMK/MA math teachers in Bengkulu City. The response of the participants after participating in the training was in the very good category as much as 95.45%. Participants said this activity was very useful for them in making teaching materials.

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 ????−???????????????????? or ????????????<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 influence in improving student learning outcomes
