The Development of Learning Activities using Problem Based Learning to Promote Mathematical Problem Solving Abilities of Grade 7th Students

Abstract

The objectives of this research were to 1) develop learning activities using problem based learning to promote mathematical problem solving ability 2) compare mathematical problem solving ability with
70 percent criteria 3) compare learning achievement between pre-test and post-test results 4) study student’s learning satisfaction. The sample was 36 Grade 7 students in the second semester of 2023 academic year. They were selected by random grouping, using classrooms as units. The research instruments consisted of
1) activities using problem based learning plan, 2) math problem solving ability test, 3) an achievement test, and 4) a student satisfaction questionnaire. The statistics used  this  research  were  mean,  standard deviation, and t-test

       The research findings were as follows.

1. Results of developing problem-based learning activities to promote the ability to solve mathematical problems for Grade 1 students consist of 7 steps: 1) explore the problem, 2) understand the problem, 3) learn to solve it, 4) synthesize and investigate the problem, 5) summarize and evaluate it,
   6) present new ideas. 7) Challenge the ability of learners Overall, it was the most appropriate with an average score of 4.73 and a standard deviation of 0.34;
2. the ability to solve mathematical problems were significantly higher than the 70 percent criterion at .05 level of significant ;
3. student’s learning achievement after learning activities were organized. Post-study were statistically higher than before, at the .05 level of significant;
4. student's learning satisfaction were at the highest level;
