PENGARUH MODEL PEMBELAJARAN PROBLEM SOLVING TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN KOLABORATIF PADA PEMBELAJARAN IPS

This research aims to determine the effect of the Problem Solving learning model on the critical and collaborative thinking abilities of class VIII students at MTs Negeri Gresik. This research uses a quasi-experimental model with a non-equivalent pretest posttest control group design. Data analysis used the t test (independent sample t-test). The results of the research show that the Problem Solving learning model influences the critical and collaborative thinking abilities of class VIII students at MTs Negeri Gresik. The average posttest gain score for the experimental class was 16.6, which was higher than the control class which had an average of 13.5. The average gain score for the pretest experimental class was 12.7, which was higher than the control class which had an average of 10.2. The average Self Assessment questionnaire score for the experimental class was 42.60 which was higher than the control class which had an average of 26.54. The average Peer Assessment questionnaire score for the experimental class was 37.43, which was higher than the control class which had an average of 26.60. The results of data analysis calculations using the t test, namely 0.000, are less than the significance of 0.05.
