Abstract

This study aims to describe : 1) the validity, practicality, and effectiveness of teaching materials developed by implementing virtual manipulatives and oriented to problem-based learning, 2)critical thinking and problem solving skills improvement of 8th grade students of SMP MARS Pematangsiantar by using teaching materials developed by implementing virtual manipulatives and oriented to problem based learning. This research is a development research. The development model used in this research is the Thiagarajan model. The results showed that : 1) the teaching materials developed by implementing virtual manipulatives and problem-based learning were declared valid, practical and effective- 2) there is an increase in critical thinking and problem solving skills of 8th grade students of SMP MARS Pematangsiantar by using teaching materials developed by implementing virtual manipulatives and oriented to problem-based learning. In the first trial there was an increase in critical thinking skills of 0.35 and problem-solving skills of 0.44 with moderate criteria (0.3<g<0.7). Likewise, in the second trial there was an increase in critical thinking skills 0.42 and problem solving skills 0.53 with moderate criteria (0.3<g<0.7)
