The Influence of Group Investigation Learning Implementation Judging from Learning Motivation Against Students' Mathematical Problem Solving Ability

Abstract

This study aims to determine the effect of the application of the group investigation type cooperative learning model on the mathematics problem solving ability of the seventh grade students of SMP N 7 Pesawaran This type of research is a quasi experiment. The population of this study were all students of class VII of SMP N 7 Pesawaran. The technique used for sampling is ramdom sampling. The sample in this study were students of class VII D as an experimental class and students of class VII E as a control class. The instrument used to collect document is a test of students mathematical problem solving skills. Before being used for data retrieval, the mathematics problem solving ability test instrument was first tested. Assement of the validity of the contents of the test insrument by 2 validators. Bassed on the results of the study, several conclusions were obtained. First, there is influence between models group investigation learning with conventional learning models to mathematical problem solving ability. Second, there is an influence between learning motivation on mathematical problem solving skills. Third, there is no interaction between learning models and learning motivation on mathematical problem solving abilities.
