Abstract

The research sets to examine the influence of Problem Based Learning (PBL), critical thinking ability, and collaboration toward learning outcome of Christian Junior High School (SMPK) Stelamaris Biudukfoho. Quasi experiment using non-equivalent control group design is employed in this research. The first and the second experiment group are selected based on assignment random sampling. There are 60 subjects at the eighth grade of Junior High School in the academic year of 2018/2019. The researchers apply test to measure critical thinking ability and learning outcome, whereas questionnaire is employed to measure collaboration of the students. The data analysis is three-way analysis of variance. The results reveal that there is significant differentiation of learning outcome between a group using PBL and a group using conventional method, between the students with high and low critical thinking ability, between the students with high and low collaboration. In addition, there is significant interaction of learning model, critical thinking ability, and collaboration toward students’ learning outcome. It means that students’ learning outcome depends on the learning model, critical thinking ability, and collaboration of the students
