Abstract

The study aims to describe the implementation of students' worksheets based on problem-based learning to improve students' science process skills, the activity of students' science process skills, and the student's responses. The research used is pre-experimental with one group pre-test post-test research design using one experiment class. The research is conducted at junior high school 6 Gresik with a sample of one class, namely VII-G, consisting of 30 students. The data collection method used are observations, written tests, and questionnaires. The data analysis technique used is quantitative descriptive. The result of the study shows that the learning implementation for three meetings got the average criteria carried out well. The science process skills observed are formulating problems, formulating hypotheses, identifying variables, interpreting data, making conclusions, and communicating. The average N-gain score obtained is 0.88 in the high category, which indicates that the students' science process skills have increased. The learning process also responds positively, with an average response of 93% with very effective criteria. Based on the description above, it can be concluded that learning by using students' worksheets based on problem-based learning can enhance students' science process skills on environmental pollution material.

Abstract

This study aims to describe the influence of interactive multimedia on students' science literacy in the new normal era and student responses after learning using interactive multimedia on energy flow materials. The type of research used is pre-experimental design research through one group pretest-postest design. The subjects in this study were 31 students of class VIIC in Muhammadiyah Junior High School 2 Taman Sidoarjo, even semester of the 2021/2022 academic year. Data collected by techniques use observation, tests, and questionnaires. Research instruments include observation sheets for the implementation of learning, science literacy tests, and student response questionnaire sheets. The data were analyzed descriptively using the N-Gain test, the implementation observation sheet, and the response questionnaire. The results showed that the implementation of learning using interactive multimedia on energy flow materials got the criteria for being carried out properly. Students' science literacy skills increased from an average pretest score of 38.5 to 81 on the posttest, with an average N-Gain score of 0.69, categorized as moderate. The learning process and the use of interactive multimedia applications on energy flow materials were also responded to positively by students. Based on the description above, learning using interactive multimedia on energy flow materials can improve students' science literacy skills in the new normal era.
