摘要：This research is aimed at investigating the effect of problem-based teaching on concept mastery of science and science process skills of grade V students of primary school. This is a quasi experimental research with nonequivalent-groups pretest and posttest design. The experimental class was students of class VB SD Negeri 01 Labuhan Sumbawa (n=38) and control class was students of class VA SD Negeri 01 Labuhan Sumbawa (n=36). The data were analyzed using the descriptive statistics and MANOVA. The result of the research is as follows. (1) Problem-based teaching has a significant effect and better than conventional teaching on students’concept mastery of science (Sig.=0.000;p<0.05). (2) Problem-based teaching has a significant effect and better than conventional teaching on students’ science process skills (Sig.=0.00;p<0.05). The research findings imply that teachers need to change their teaching model into problem-based teaching and the teachers should become mediators and facilitators in the intructional process.
