Abstract

This study aims to describe the implementation of learning, improving learning outcomes, and student responses to problem-based learning. The type of research used is the pre-experimental design, with the research design used is "one group pretest-posttest design". Data collection was carried out using test methods in the form of pretest and posttest. The research instruments used included implementation observation sheets, pretest and posttest sheets, and student response questionnaire sheets. The results of the analysis of the implementation of learning show that the implementation of learning is running effectively, the N-Gain test has obtained a score in the high category, the student's response shows a very good category. Based on the output "Unpaired t-test" is <0.05. Shows the influence of problem-based learning on student learning outcomes. Thus, the application of problem-based learning is effectively applied in the learning process.

Abstract

This study aims to describe students’ written communication skills, the implementation of learning activities, and students’ responses after the application of the Project Based Learning (PjBL) model on environmental pollution material. This research employed a pre-experimental method with a one-group pretest-posttest design. The research subjects consisted of 34 students of class VII-H at SMPN 43 Surabaya. The research instruments included a written communication skills test sheet, a learning implementation observation sheet, and a student response questionnaire. Data were collected through pretest, posttest, observation, and questionnaire. The data were analyzed using quantitative descriptive analysis. The results showed that the improvement in students’ written communication skills based on the N-Gain score was categorized as moderate (56%) and high (44%). The implementation of learning activities in each meeting was categorized as very good. Students’ responses to the implementation of the Project Based Learning model showed a high percentage and were categorized as very good. In conclusion, the implementation of the Project Based Learning model on environmental pollution material can improve students written communication skills.
