THE DIFFERENCE OF MATHEMATICAL PROBLEM SOLVING ACHIEVEMENT OF PUBLIC JUNIOR HIGH SCHOOL BASED ON LEARNING APPROACH

This paper is the result of a study to investigate the difference of the students’s achievement in mathematical problem solving (MPS) based on learning approach. The research is static and quasi-experimental group posttest only. The population was all of students of upper and middle level public Junior High School in Bandung, West Java, Indonesia. One school of each level and two classes of each school were involved as samples. The research also investigate students’ mathematical prior knowledge (MPK) either in upper or in the middle level school. One way Anova and two way Anova are used to analyze the data. The research results are: (1) The students in PBL classroon get better achievement in MPS test than the students in conventional one; (2) There is no interaction between PBL and MPK towards MPS; (3) There is no interaction between learning approach and school level.
