Abstract

This study supports 1). Knowing the differences in problem-solving abilities in students before and after being taught with the JUCAMA learning model; 2). Knowing students' problem solving skills between before and after being taught with the JUCAMA learning model in high initial students; 3). Knowing students' problem solving skills between before and after being taught with the JUCAMA learning model in students with low initial ability; 4). Conversation between initial ability and learning model on students' problem solving. This study uses quantitative research with a quasi-experimental type of research. The results showed 1). 95% (16.67> 9.98, tcount = 7.816> t table = 1.71; 2). The average problem solving ability of students in early ability students was higher after being taught with the JUCAMA learning model than before at 95% confidence level (16.09> 13.72, tcount = 15.53> ttable = 1.81); 3. The average problem solving ability of students in early ability students is lower after being taught with the JUCAMA learning model than before at 95% confidence level (10.31> 7.25, tcount = 5.21> ttable = 1.75). While the results of the interaction test showed there was no interaction between the initial ability and the learning model on the ability to solve students' problems at a 95% confidence level (Fcount = 0.29 <Ftable = 1.35), so that the JUCAMA learning model was suitable for use with diverse abilities . Based on the research it was also found that students needed more time than usual to solve problems of type solving problems.

Abstract

Problem solving is the main focus in learning mathematics at the primary and secondary school level. Prospective teachers must be prepared as well as possible as problem solvers and problem solving instructors. The purpose of this study was to describe the prospective teacher's ability to make a problem solving question based on category of good mathematical problem solving questions. The type of research used is descriptive qualitative.The research subjects were students of semester VI of the 2019/2020 academic year of the IAIN Takengon Mathematics Education Study Program. Based on the research results, it shows that the subjects in general already understood the theory of problem solving , but this understanding did not always directly proportional to the ability to make a mathematical problem solving question.
