Abstract

Mathematical communication ability is an important ability possessed by students. However, students' mathematical communication skills still tend to be low. An approach that can help students improve their mathematical communication skills is to use an integrated RME approach with local wisdom values which is also an effort to preserve local wisdom in Indonesia. This research is a quasi-experimental quantitative research. The sampling technique used simple random sampling. Class VII B is applied as the experimental class and VII C is applied as the control class. The data collection method consisted of a test of mathematical communication skills seen from the aspects of writing, drawing, and mathematical expression, as well as the teacher's observation sheet. The results of this study indicate that: The application of the integrated RME approach to local wisdom values has a better effect than the conventional approach on students' mathematical communication skills.

Abstract

One of learning media which is using in Problem-based learning that can improve students' conceptual understanding ability is GeoGebra. This study aims to: 1) describe the students' understanding of the concepts of SMA Negeri 1 Oheo. 2) determine the effect of problem-based learning assisted by the GeoGebra application on students' conceptual understanding at SMAN 1 Oheo. This research is pre-experimental research. The sampling technique uses simple random sampling. Class XI MIA as a research class. The data collection technique consists of students' conceptual understanding tests seen from the indicators explaining, understanding and concluding, as well as teacher observation sheets. The results of this study indicate that: 1) Students' conceptual understanding at SMAN 1 Oheo is in the high category where indicators of students being able to explain abstract concepts into a model have a 100% presentation, indicators of students being able to recognize and understand the main idea of a communication have a presentation 91.30%, and the student's indicator of being able to conclude from something that is already known material has an achievement of 78.26. 2) There is an effect of problem-based learning assisted by the GeoGebra application on students' understanding of concepts at SMAN 1 Oheo
