IMPROVING PHYSIC LEARNING ACHIEVEMENT ON DYNAMIC ROTATION THROUGH PROBLEM BASED LEARNING METHOD ON GRADE XI 3 SCIENCE PROGRAM AT CITEUREUP 1 SENIOR HIGH SCHOOL
The background of the action reasearch was the students’ low achievement in understanding dynamic rotation in grade XI 3 Science Program in the school year of 2015/2016. The achievement was only 12,5 %. The action research was aimed to improve the learning acvievement on the concept through Problem Based Learning. The rersearch was conducted in two cycles. Every cycle was delivered in four stages: planning, acting, observing, and reflecting. A test was given on every cycle. The instrument of the test was validated by the expert. The result of the research showed that PBL improve the student’s achievement. The pre research acvievement was around 12,5% with an average of 56,23. After the first cycles, the result showed 45,0% achievement with an average of 74,90. And the reasult on the second cycle showed 87,5 % achievemetn with an average of 87,50. Therefore, PBL improve the students achievemtn in understanding Dynamic Rotation concept
