Abstract

The research aims to improve the mathematical communication skills of SMP Negeri 1 Kolang students by applying a problem based learning model assisted by GeoGebra. The research subjects were 30 grade VIII students of SMP Negeri 1 Kolang. The type of research used was classroom action research which was carried out in 2 actions. The two actions were carried out in 4 meetings in learning and 2 evaluations. The results of the study show that mathematical communication skills can improve after using the GeoGebra assisted problem based learning model. The increase was obtained through an average students score of 42.7 with 7% classical mastery to 67.5 with 50% classical mastery in action I and to 83.05 with 87% classical mastery in action II. An increase was also obtained through teacher observation of 2.56 in action I to 3.30 in action II. So it was concluded that the application of the problem based learning model assisted by GeoGebra can improve the mathematical communication skills of students of SMP Negeri 1 Kolang.

Abstract

The research aims to increase the motivation and learning outcomes of students at UPT SMP Negeri 8 Medan by implementing the Teaching at Right Level (TaRL) approach. The subjects in this research were 30 students in class VIII-2 UPT SMP Negeri 8 Medan. This research is classroom action research carried out in 2 cycles. The two cycles carried out 4 learning meetings and 2 evaluations. The results of the research show that students' learning motivation has increased, in the pre-cycle the average was 65.2 in the sufficient category, then in the first cycle it increased to 74.9 in the sufficient category. In cycle II, the average learning motivation of students increased to 83.3 in the good category, while for learning outcomes there was an increase in classical completeness in the pre-cycle by 20%, then in cycle I it increased to 50%, improvements were made in cycle II, classical completeness was the result student learning increased to 87%. So, it can be concluded that implementing the TaRL approach can increase student motivation and learning outcomes at UPT SMP Negeri 8 Medan.
