Abstract

The problem in this study is the students' mathematical problem solving ability is still low, the cause is that the learning device designed by the teacher has not supported the formation of these abilities. Through learning device development will improve students mathematical problem solving. This is a development research with Plomp model. The Statistic Group Comparison Design is the experimental design being used in this research. Research result reveals that: (1) Learning device developed by the researcher is 3. 55 in average resulted from validation result by experts and it is a very valid category. (2) On average both teacher and students respond toward learning device based on Problem Based Learning as a whole is valid with 80.675% average percentage and in including in a good or practical respond criteria. (3) Students learning result reveals sig. score (2-tailed) 0.014 smaller than (0.05) score, hence is rejected and is accepted. Conclusions obtained that learning device based on Problem Based Learning with a scientific approach has a significant impact toward class VIII students of Islamic Junior High School (MTs) ability in solving mathematics problem
