The Effect of Problem Based Learning Applied With Blended Learning on Students’ Problem Solving Skills

Abstract

This research aims to determine the influence of the PBL model applied through blended learning on improving the problem-solving ability of learners on the concept of light topic physics at the junior high school / MTs level. The research method used by the one group pretest posttest design data was obtained through the provision of a problem-solving test consisting of pre-test and post-test. After the pre test, blended learning was conducted 3 times after that post test was carried out. The sample in the study was a class VIII student at integrated MTs in one of Gorontalo's 25 cities. Research and analysis results show the influence of blended learning on problem-solving skills. The ability to solve problems can be seen from the improvement of learners' problem-solving ability on the concept of light. This can be seen from the comparison of the value obtained in the pre-test and post-test analyzed using N-Gain which is as wide as 0.77 with a high interpretation. Other influence indicators can be seen from the pretest average of 37% while the posttest average is 86%. Improvements also occur in all problem solving indicators.
