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

Mathematics learning in schools is still abstract and not yet relevant to students' lives. Mathematics learning should be linked to student activities such as scouting extracurricular activities. There are many scouting technical activities that can be used as contextualization in mathematics learning such as ceremonies, exploration, estimating, marching, pioneering, and semaphore. Thus, this study aims to identify mathematical concepts contained in scouting activities, especially in the construction of creative flagpole pioneering. This study is a qualitative study with an exploratory approach. Data collection methods used are observation, interviews, and documentation. The study was conducted on students who participate in scouting extracurricular activities at SMAN 2 Kendari, located on Jln. Sisingamangaraja, Rahandouna Village, Poasia District, Kendari City, Southeast Sulawesi Province. The results of the study show that in the pioneering flagpole creation building there are geometric concepts, namely rectangular, square, right triangle, acute triangle, obtuse triangle, right trapezoid, isosceles trapezoid, arbitrary trapezoid, right angle, acute angle, obtuse angle, overlapping lines and intersecting lines. and geometric transformations, namely rotation. These results provide recommendations to teachers to be able to use the pioneering building as an introduction to mathematical concepts.
