Upaya Meningkatkan Kemampuan Komunikasi Matematis pada Materi SPLTV dengan Pedeketan Culturally Responsive Teaching

Abstract

This research was conducted with the aim of improving the mathematical communication skills of class X TKJ SMK Bina Teknologi Purwokerto in the 2023/2024 academic year which are still lacking in the material of the Three Variable Linear Equation System (SPLTV) by implementing the Problem Based Learning model with the Culturally Responsive Teaching approach. One effort to create a learning environment that supports, encourages and is able to improve students' mathematical communication skills is by using the Culturally Responsive Teaching (CRT) approach or culturally responsive learning. This type of research is classroom action research which is carried out in two learning cycles. Data collection was carried out using a mathematical communication skills test, observation sheets and documentation. Data analysis was carried out by comparing the results of students' communication skills tests in the pre-cycle, cycle I and cycle II. Based on the results of the research and discussion, it can be concluded that the use of the Problem Based Learning learning model with the Culturally Responsive Teaching approach can improve students' mathematical communication skills as shown by the results of the students' mathematical communication evaluation test. abilities and observation results. Before the action was taken, the class average was 65.5. After the action was implemented, the class average increased to 73.6 in cycle 1 and 79.9 in cycle II. So it can be concluded that there is an increase in the results of the communication ability test.
