Peningkatan Kemampuan Pemecahan Masalah Matematis Melalui Model Problem Based Learning dengan Menggunakan Soal-soal Berbasis Budaya Lokal

Abstract

The ability to solve problems is part of the purpose of learning mathematics in junior high school, but the reality that occurs in the field is not the case. This can be seen from the lack of trained students and find it difficult to work on the stages of problem solving so that students' mathematical problem-solving abilities are still relatively low. Therefore, Problem Based Learning (PBL) learning model is used by using questions based on local culture. This study aims to look at differences in the improvement of students' mathematical problem-solving abilities between those through the PBL learning model using questions based on local culture and students who use conventional learning in class VII. The method is Quasi Experimental Design with the Random Sampling Cluster technique, VIIB class as the experimental and the VIID class as the control. Data processing is performed by the formula N-gain, then hypothesis testing is done using the t test. From the results of data analysis shows that there are significant differences in the improvement of students' mathematical problem-solving abilities between those who go through the PBL learning model by using questions based on local culture and those using conventional learning.

Peningkatan Kemampuan Pemecahan Masalah Matematis Melalui Model Pembelajaran Problem Based Learning Terintegrasi Budaya Lokal Kerinci

“…Peneliti mengambil kesimpulan bahwa berdasarkan hasil pembahasan di atas penelitian ini sejalan dengan temuan penelitian (Reno et al, 2017) yang menemukan bahwa mengajar siswa memecahkan masalah matematika dengan menggunakan model Problem Based Learning (PBL) dengan nuansa etnomatematika bermanfaat. Selain itu, penelitian (Vera et al, 2021) menemukan bahwa siswa pada kelas eksperimen yang diajar melalui pembelajaran PBL dengan soal berbasis budaya menunjukkan pertumbuhan kemampuan memecahkan masalah matematika yang lebih tinggi. Hasil analisis data menunjukkan adanya perbedaan yang signifikan antara siswa yang menggunakan model pembelajaran PBL dengan soal-soal berbasis budaya lokal dengan siswa yang menggunakan metode pembelajaran konvensional dalam kemampuannya memecahkan masalah matematika.…”

Edmodo-Based Mathematical Learning Analysis

“…Edmodo is a testament to the rapid development of existing internet technology. Edmodo is a social media for teachers and students or lecturers and students that serves to share ideas on the agenda of activities and assignments that can create interaction between teachers and students, so that edmodo allows it to be applied as a learning medium (Vera, Yulia, & Rusliah, 2021). According to Wardani (2017) there are several advantages of Edmodo, namely: User Interface: Adapting a facebook-like appearance simply; Compatibility: Edmodo supports previewing different types of file formats; The Edmodo application can not only be accessed using a PC (laptop/desktop) but can also be accessed using gadgets based on Android OS.…”
