The EFFECTIVENESS OF PROBLEM BASED LEARNING ASSISTED WITH DIORAMA MEDIA TOWARDS LEARNING RESULTS OF SCIENCE MATERIALS RELATIONSHIP BETWEEN LIVING THINGS IN ECOSYSTEMS IN CLASS V STUDENTS OF MI ARROSYAD BERGASLOR

This study aims to determine the effectiveness of the use of problem based learning with the aid of diorama media on science learning outcomes regarding the relationship between living things in ecosystems in class V MI Arrosyad Bergaslor Semarang Regency in the 2021/2022 academic year. This research is a quantitative pre-experimental research with One Group Pretest-Posttest design. The sampling technique was carried out by purposive sampling technique. Data was collected by means of tests, observations, and documentation. The test instrument was tested using validity test, reliability test, difficulty level test and test of differentiating power of questions. The data analysis technique used is the Paired Sample T Test. The results showed that the science learning outcomes of the fifth grade students of Al Basith obtained an average pretest score of 62.40 and posttest of 82.77. Based on these data, student learning outcomes have increased by 20.37. This is evidenced by the Paired Sample T Test, the value (tcount11,598 > ttable 2.048) and the significance value (P-value 0.000 < 0.05), based on these data, it can be concluded that Ho is rejected and Ha is accepted, meaning that the use of problem based learning assisted by diorama media is effective on science learning outcomes for the material on the relationship between living things in the ecosystem in class V MI Arrosyad Bergas Lor Semarang Regency in the 2021/2022 academic year.
