Comparison of Effectiveness between Contextual Teaching and Learning (CTL) and Problem-Based Learning (PBL) Approach on the Interest of Junior High School Students

The purpose of this study is to reveal the effectiveness of contextual teaching and learning (CTL) and problem-based learning (PBL) approaches on students' interest. This study was quasi-experimental research with pretest-posttest group design. The population of this research was all students of grade VIII of State Junior High School 9 Yogyakarta. Then, the sample involved 34 Junior High School students in each class that has been taken using purposive random sampling. The first experiment class used Contextual Teaching and Learning (CTL) approach, and the second one used the Problem-Based Learning (PBL) approach. The instrument was the interest questionnaire which was given to the students before (pretest) and after treatment (posttest). The data were analyzed using one sample t-test with a significance level of 5% to find out the effectiveness of CTL and PBL approaches on students' interest. Then, the data were analyzed using independent sample t-test to compare the effectiveness of both approaches. The results showed that both CTL and PBL methods were effective in terms of students' interest mean scores. The comparison result demonstrated that CTL was more effective than PBL to improve the interest of junior high school students.
