MODUL MATEMATIKA BERBASIS MODEL KOOPERATIF TIPE STAD DENGAN METODE PENEMUAN TERBIMBING PADA POKOK BAHASAN TEOREMA PHYTAGORAS

Abstract

Abstrak:

Penelitian ini bertujuan untuk mengetahui proses pengembangan dan menilai kualitas bahan ajar matematika berbasis model kooperatif tipe STAD dengan metode penemuan terbimbing pada pokok bahasan teorema Phytagoras yang valid, praktis, dan efektif. Jenis penelitian yang digunakan adalah penelitian research & development (R&D) dengan mengacu pada model 4-D (Four D models). Berdasarkan hasil uji coba terbatas yang dilakukan, diperoleh bahwa (a) hasil validasi bahan ajar adalah  3,50 pada kategori valid karena setiap aspek untuk setiap jenis perangkat berada pada interval 3 , (b) hasil pengamatan keterlaksanaan bahan ajar matematika berbasis model kooperatif tipe STAD dengan metode penemuan terbimbing adalah 1,89 menunjukkan bahwa komponen pengamatan keterlaksanaan berada pada kategori terlaksana seluruhnya (praktis) atau berada pada interval , (c) dari keempat kriteria keefektifan yaitu, kemampuan guru mengelola pembelajaran, keterlaksanaan bahan ajar bagi siswa, respon siswa dan tes hasil belajar, dapat disimpulkan bahwa pada tahap uji coba terbatas dilaksanakan, perangkat bahan ajar matematika berbasis model kooperatif tipe STAD dengan metode penemuan terbimbing telah memenuhi kriteria kevalidan, kepraktisan, dan keefektifan.

Abstract:

The study was a developmental research aiming at determining the process of developing and assessing the quality of teaching materials based on cooperative model of STAD type with guided discovery method on valid, practical, and effective Pythagoras theory subject. The type of research used was Research & Development (R&D) by referring to the 4-D model (Four D Models). The subjects of the study were the students of class VIII₇ MTsN Model Makassar with a total of 40 students. Based on the results of the limited trial conducted, it was found that (a) the validation result of the teaching materials was 3.50 in the valid category as every aspect for each type of device was at the interval of 3≤ M <4, (b) the observation result of the implementation of mathematics teaching materials based on cooperative model of STAD type with guided discovery method was 1.89 indicating that the observation component of the implementation was in the category of executed entirely (practically) or it was at the interval of 1.5 ≤ X ̅≤ 2, (c) of the four criteria of effectiveness that was, the teacher’s ability to manage the learning, the implementation of teaching materials for students, the students’ responses and learning result test, it can be concluded that at the limited trial stage implemented, the mathematics learning materials based on cooperative model of STAD type with guided discovery method had fulfilled the criteria of validity, practicality and effectiveness.
