Development of the Cooperative Learning Model to Improve Students’ Mathematic Generalization Ability

Abstract

This study aims to produce cooperative learning models in improving the mathematical generalization abilities of junior high school students that are valid, practical, and effective. This research is research and development by adopting the Plomp model design which consists of five phases, namely initial investigation, design, realization/construction phase, test phase, evaluation, and revision and implementation phase. Data collection was carried out using several instruments in the form of needs analysis questionnaires, validation questionnaires, observation sheets, teacher response questionnaires, and tests of mathematical generalization ability. The data collected was then analyzed using qualitative and quantitative methods. The results of the study show that both teachers and junior high school students really need to develop learning models that can improve students' mathematical generalization abilities. In addition, other findings state that the learning model developed is proven to be valid, practical and effective for general use. Developing cooperative learning models can further improve students' mathematical generalization abilities because they are designed based on actual needs and problems. For that a teacher must be able to design a learning model.
