Development of science teaching materials based on Science Technology Society (STM) and its influence on learning outcomes of fourth grade students of MIN Medan Tembung

This study aims to determine the feasibility,
effectiveness of teaching materials based on STM science and to
know the improvement of learning outcomes by using STM-based
science teaching materials. The background in this study is a) The teaching materials used by the teacher have not brought up
current issues and helped solve the problems of the surrounding
community. b) The textbooks used present little information that is not sufficient to help students c) Text books have not been able to lead students to construct their own knowledge d) learning system that is still classical and based on the handbook of natural science subjects that affect low student learning outcomes. this research will be categorized into the type of research development research in this study which will be developed namely STM-based teaching materials. the development of STM-based teaching materials used was modified and adapted to the Dick and Carey development model. The stages in this study will be grouped into three groups, namely: 1) preliminary study 2) planning, 3) Validation and testing. Subjects in this study were grade IV students of MIN Medan Tembung, Medan, totaling about 32 students. In the experimental class and grade IV b as the control class amounted to 34. The results of this study showed an increase in student learning outcomes before using STM-based teaching materials with after using STM-based teaching materials in the experimental class, namely: in the experimental class totaling 32 students on the pretest there are 13 students complete category with a percentage of 40.62% while students in the incomplete
category there are 19 students with a percentage of 59.37%. while the posttest results of students in the complete category are 32 students with a percentage of 100%. As for the average value of the pretest results is 72.18 while the average value of the posttest results is 88. It can indicate that there is an increase in student learning outcomes by using STM-based teaching materials by not using STM-based teaching materials. expected to be a reference for teachers in carrying out the teaching and learning process in science learning, especially for the level of MIN / SD in class IV natural resource material.
