Whereas, 90.32% of students' score are still below the minimum completeness criteria (KKM) in science subject. Students are able to achieve 2 indicators of Polya model problem solving namely understanding the problem and making plans. However, students have not yet been able to achieve the other 2 indicators, namely implementing the plan and checking again. The students found the difficulties in interpreting the Problem-type questions. They got difficult in understanding the intentions of the problem so that there is an error in compiling a strategy that results in students experiencing confusion in writing each answer. So training is needed in working on problem solving problems.]]>
