PENGARUH PERSEPSI ATAS PENDEKATAN KONSTEKSTUAL DAN KOLABORATIF TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA MURID SMK

Abstract

This study aims to analyze the effect of contextual and collaborative learning approaches on students’ mathematical problem-solving ability at vocational high schools (SMK) in Tangerang Regency. A quantitative approach with a correlational design was applied. The population consisted of 1,353 students of SMKN 1 Kabupaten Tangerang and SMKN 10 Kabupaten Tangerang, and 93 respondents were selected using Slovin’s formula with proportional sampling. The instruments used were perception questionnaires on contextual and collaborative approaches and a problem-solving test. Data analysis employed multiple regression using SPSS 25. Results showed: (1) contextual and collaborative approaches simultaneously had a significant effect on problem-solving ability (Sig = 0.000, F = 334.217); (2) contextual approach significantly affected problem-solving ability (t = 5.805, Sig = 0.000); (3) collaborative approach significantly affected problem-solving ability (t = 7.342, Sig = 0.000). The coefficient of determination (R²) indicates 88.1% of problem-solving ability is explained by the two approaches, while 11.9% is explained by other factors. These findings suggest that contextual and collaborative learning strategies are effective in improving students’ critical thinking, creativity, and collaboration skills needed for future challenges.
