Development of Problem- Based Teaching Materials for The Fifth Graders of Primary School
Packaging interesting learning materials is a key element in the achievement of quality learning results so it is important to do the development of teaching materials. The aim of this research is to develop teaching materials of science using problem based learning model for elementary school students. he developed science teaching materials should accommodate the interests of strengthening students' knowledge and thinking skills. This research method using development research refers to Thiagarajan model, consisting of define, design, develop, and dessiminate stage. The define stage is done curriculum analysis, needs analysis, concept analysis and student analysis. Design stage is done design of teaching materials. Develop stage is tested the validity and practicality of teaching materials through validation sheet and questionnaire response of teachers and students. Dessiminate stage is done limited-scale deployment to see the effectiveness of teaching materials on the achievement of activities and student learning outcomes. The results showed that the learning materials based on problem based learning developed obtained validity, practicality, and high effectiveness.
