Abductive-Deductive Strategy, Problem Solving Ability

The background in this research is the lowerness of students’ problem solving ability in SMPN 4 Kerinci. According to the prior study, the abductive-deductive strategy can improve the stundets’ problem solving ability therefore we need to solve the lowerness of students’ problem solving ability by using abductive-deductive strategy in learning process. This research aims to improve students' problem solving ability by using abductive-deductive strategies. This research used the quasi-experimental method with the Control Group Pretest-Posttest design.
