Application of Problem-Solving Approach Using Model Problem Based Learning to Improve Ability Problem Solving and Student Self-Efficacy
Keywords:
Problem Based Learning, Problem Solving Abality dan Self-EfficacyAbstract
To improve students' problem-solving abilities and self-efficacy, this study seeks to ascertain the impact of teaching mathematics using a problem-solving strategy. With a one group pretest-posttest design, a quantitative method was adopted. Using a basic random selection technique, a sample of VIII C grade students from one of the State Junior High Schools in Yogyakarta served as the study's population. In this study, a self-efficacy questionnaire, an observation sheet, and a problem-solving skill test were utilized to collect data. Because the N-Gain score data were evenly distributed and homogeneous, data analysis was done using IBM SPSS statistical software version 21 and the t-test. H0 is rejected when the statistical significance results show that equal variances are not considered to be 0.00 less than 0.05. The findings indicated that students who utilized a problem-solving method while using a problem-based learning model did better in mathematics after studying using a problem-solving strategy while using a problem-based learning model
