Abstract

This study aims to determine the effectiveness of the integrated science learning type connected to achieving basic competencies and improving science process skills. This study uses a 4-D development model that is defined, design, develop, and disseminate with one-group posttest design implemented in 5th-semester students of Chemistry Education, University of Bengkulu. The research instrument is a posttest question to measure learning outcomes and observation sheets to measure science process skills. The teaching materials used are sourced from part of the process and the results of the activity test of palm oil endophytic bacteria ethyl acetate extract against Fusarium oxysporum f.sp. by TLC-bioautography is packaged in the form of learning videos. The results showed that the Integrated Science type of Connected model was used effectively to improve student learning outcomes and science process skills.

Abstract

This reserach was conducted to improve conceptual understanding and critical thinking ability of fourth-semester students of the Science education study program, Bengkulu University by applying PBL. The research method used in this study is quasi experimental, which in its implementation uses single class or one group pretest-posttest design. The test question was the instrument used in this study. The findings showed that there was an improvement in students‘ conceptual understanding and critical thinking ability of students‘ since implementing problem-based learning models in environmental chemistry courses. This improvement can be seen from the results of the gain test for each class group on the test of conceptual understanding and critical thinking ability which are in the "medium" category, while the t-test results for concept understanding and critical thinking ability show a significant difference (0.000 <0.05). ), In other words, the implementation of the PBL learning influences the students‘ conceptual understanding and critical thinking ability. Further the implementation of the problem-based learning model in teaching and learning process presents problems with real conditions so that it can stimulate students to not only think and understand at the rote level but also interpret the problem. Quiet in-depth research on the implementation of problem-based learning models in learning is highly recommended to get more comprehensive results.
