The Impact of Learning Strategy of Problem Solving and Discovery towards Learning Outcomes Reviewed from Students Learning Motivation

The research aims at examining: (1) the impact of Problem Solving Strategy and Discovery Learning Strategy on mathematics learning outcomes, (2) the impact of learning motivation on mathematics learning outcomes, (3) the interaction between learning strategies seen from the learning motivation on mathematics learning outcomes. Type of the research is quantitative with a quasi-experimental design. The population of the research is all of the 7th-grade-students at one of state middle school at Surakarta Central Java, Indonesia. A total of 57 students from two different classes were involved in the study, assigned as experimental group and control group. They were selected through cluster random sampling technique. The group which was assigned as the experimental group was instructed through a problem-solving strategy whereas the other group was discovery learning. Data collection techniques used the method of test, questionnaire, and documentation. The technique of data analysis was the two-way analysis of variance. From the analysis, it was concluded that: (1) there are impacts of Problem Solving learning strategy and Discovery Learning on mathematics learning outcomes, (2) there are impacts of student learning motivation on mathematics learning outcomes, (3) there is no interaction between learning strategies and learning motivation on mathematics learning outcomes.
