Abstract

The purpose of this research is to determine whether there are differences in the understanding of the concept of students who learn by applying the model Problem Based Learning with Group Investigation. This research in to the type of quasi-experimental design of non-equivalent pretest-posttest control group. The samples taken were class XI IPA 2 (experimental class I) and class XI IPA 3 (experimental class II). The instrument applied was a learning outcome test containing 5 items. Data analysis was calculated using analysis techniques: descriptive and inferential. The results of the descriptive data obtained mean scores of 44.81 pretest and 76.54 posttest for the experimental class I, while the experimental class II scored 47.54 pretest and 84.14 posttest. From the independent sample test, it was obtained a sign score: 0.000 at a significance level of 5%. This means that H0 is rejected, so it was decided that the level of conceptual understanding for the model is Problem Based Learning different from the level of concept understanding in the model Group Investigation.

Abstract

This study aims to produce mathematics worksheets for high school students that are in accordance with the characteristics of students and meet valid and practical criteria. This worksheet is expected to be used as one of the learning media for students to develop their special abilities in mathematics. This research is a research and development using the Instructional Development Model (MPI). The product developed in this study is a Think Talk Write (TTW)-based math worksheet. The data collection instrument used is a questionnaire. The data analysis technique used is the data analyzed using data analysis techniques of validity and practicality. The results showed that the TTW-based math worksheets that met the criteria were valid and practical. So it is recommended for further research in order to continue by reviewing its effectiveness in improving students' mathematical problem solving abilities.
