Abstract

This study aims to determine the problem solving ability of  the 9th grade students of  Banyubiru 1 and 2 Junior High School in 2019/2020 in the material of wave, and sound. This is a survey research with descriptive qualitative analysis. The instrument used was an integrated test with Polya's model problem solving steps and interview guidelines. Test questions tested consists of 2 problem descriptions. The result shows that the ability of the students  problem solving ability was still at the low level which is at 68.97%. Whereas,  90.32% of students' score are still below the minimum completeness criteria (KKM) in science subject. Students are able to achieve 2 indicators of Polya model problem solving namely understanding the problem and making plans.  However, students have not yet been able to achieve the other 2 indicators, namely  implementing the plan and checking again. The students found the difficulties in interpreting the Problem-type questions. They got difficult in understanding the intentions of the problem so that there is an error in compiling a strategy that results in students experiencing confusion in writing each answer. So training is needed in working on problem solving problems.

Abstract

STEM is one of the learning paradigms that integrates science, technology, engineering and mathematics. The combination of several learning methods is implemented to make students achieve certain abilities, like problem solving skills. Problem solving becomes a very important part in learning because it can motivate students and make them having a better cognitive level. The purpose of this study is to describe the effect of STEM learning on physics material applied in schools to the problem-solving abilities of students. The method used in this research is meta-analysis where the researcher analyzed several articles as needed. Articles were limited to the last 5 years of publication, namely 2014 - 2019. Searching for articles used the Scholar, Eric, and Elsevier search engines. From the searching results, it was obtained 21 relevant articles according to the needs of researchers. Then, from 21 articles that were obtained as many as 86% were research articles that used questions or teaching materials as STEM-based learning media and 14% were review articles. The keywords used in the search were STEM, problem solving and physics. Based on the analysis conducted it can be concluded that learning through the STEM approach can improve students' problem solving abilities.
