Abstract

This aim of this research is to produce a valid and practical teaching material on the matter 3-dimensional-space based Science, Technology, Engineering, and Mathematics (STEM) Problem-Based Learning and to know the potential effect from it. This research is qualitative with Design Research method. The subject in this research is 44 students form X MIA 4 SMA Negeri 19 Palembang. The stage of this research is preparation, formative evaluation consist of self evaluation, development, and field test. The data collection techniques are walktrough, documen, observation, and test. Based on this result, it has gained a valid teaching material on the matter 3-dimensional-space based Science, Technology, Engineering, and Mathematics (STEM) Problem-Based Learning in its content, construct, and language after passing the expert review and one-to-one stage. The practicabillity of this teaching material is looked from small group development stage. The potential effect from this teaching material is looked from the test result after learning process. The result of the test percentage is at 54% have reached the Minimal Complete Criteria. It shows that students’s book based STEM Problem-based Learning can be used in learning of distance in 3-Dimensional-Space lesson.

Abstract

This research is aimed to describe students’ problem solving skill in mathematics learning using abductive-deductive strategy. This research is descriptive research with 30 students of X.3 class at SMAN 1 Indralaya Utara as the subject. Learning process accords to characteristic and steps of abductive-deductive strategy in mathematics learning. The technique for collecting data is a test which includes of three problems. According to the results of research, it is obtained that representation of students’ problem solving skill in mathematics learning using abductive-deductive strategy on X.3 class at SMAN 1 Indralaya Utara is medium with these details: 2 students have very high problem solving skill or the percentage is 6,67%, 12 students have high problem solving skill or the percentage is 40%, 11 students have medium problem solving skill or the percentage 36,67%, and 5 students have low problem solving skill or the percentage is 16,67% and 0% or nothing who have problem solving skill with category very low. Furthermore, the understanding problem indicator has the highest percentage at 89,63%. Indicator of making a plan has the percentage at 63,7%, indicator of carrying out the plan has the percentage at 45,56%, and the looking back indicator has the lowest percentage at 16,11%.
