This is quasi experiment that use non equivalent group design and anacova nonfaktorial for analyze the results. Results of this research show that project-based learning doesn’t give different effect on students metacognitive skill even if compared by control class that learning by multistrategy. Students metacognitive skill increase to 3,2% whether students in control class increase to 5,5%. This result show us that PBL strategy must be applicate on certain condition. Project-based learning base on this research can improve not only students retention achievement, it also predict can improve students skill process, confidence, and their attitude.
