Abstract

This study aims to describe students' mathematical abilities assisted by LKS with the STAD type cooperative learning model through the Hand On Mathematical technique. Researchers used a quantitative approach in the form of Quasi Experiment. The study population was class VIII SMP N 43 Padang and the samples of this study were students of class VIII.1 as the experimental group who received treatment with the STAD type cooperative learning model through hand on mathematics techniques and VIII.2 as the control class who received conventional learning. The research instrument is in the form of a final test to see the understanding of mathematical concepts and problem solving. The results of the analysis show that: 1) The understanding of mathematical concepts taught by the STAD-type cooperative learning model through the hand on mathematics technique with LKS-assisted is better than that taught by conventional learning, 2) The mathematical problem-solving ability taught by the STAD-type cooperative learning model through the STAD-type cooperative learning technique. Hand on mathematics assisted by LKS is better than what is taught with conventional learning in class VIII SMP N 43 Padang.

Abstract

The lack of student interest in learning mathematics is caused by the teaching materials used not being able to make students active so that student scores have not reached the Minimum Completeness Criteria (KKM). School teaching materials contain many questions with almost the same level of difficulty and solution methods so that students get a little bored of doing them. This research aims to develop mathematics learning media in the form of comics with Contextual Teaching and Learning (CTL) nuances to improve the mathematics learning outcomes of class VII students at SMP N 20 Jambi City. In this development it is expected to obtain valid mathematics learning media results. This type of research is development research that produces a product in the form of learning comics. The development of this comic uses the ADDIE model which consists of 5 stages, namely the Analyze, Design, Development, Implementation, Evaluation stages. The research subjects were class VII students of SMP N 20 Jambi City. Learning device validation was carried out by mathematics education experts and Indonesian language education experts. The overall validation results for comic media are very valid with a success rate of 85.52%. With this it can be concluded that the development of comic media with Contextual Teaching and Learning (CTL) nuances can be used as teaching material.
