Abstract

This study aims to analyze improvements in students’ cognitive abilities regarding the topic of vibrations and waves through cooperative learning aided by the PhET Simulation software. This is a quantitative study with a pre-experimental approach using a one-group pretest-posttest design. The study population consists of all eighth-grade students at SMP Negeri 15 Ambon. The research sample was selected using purposive sampling, resulting in Class VIII5, consisting of 26 students. Research data were collected through test and non-test instruments. The test instruments consisted of pretests and posttests to measure students’ cognitive abilities, while the non-test instruments consisted of Student Worksheets (LKPD) used during the learning process. The data were analyzed descriptively by calculating cognitive ability scores before and after instruction, as well as the improvement using the N-Gain test. The results showed that the students’ average pretest score was 10.47, classified as failing. During the learning process, the average achievement score based on the Student Worksheets was 90.84, classified as very good. After participating in PhET-assisted cooperative learning, the average posttest score increased to 87.75, which is classified as good. The N-Gain score of 0.86 indicates that the improvement in students’ cognitive abilities falls into the high category. It is hoped that PhET-assisted cooperative learning can serve as an effective alternative teaching method to enhance students’ cognitive abilities in the subject matter of vibrations and waves.

Abstract

This study was motivated by the low level of student engagement in physics classes at SMP Negeri 4 Kairatu, which has resulted in low cognitive abilities among students. Therefore, it is necessary to implement a learning model that encourages students to actively discover concepts through activities such as observing, formulating problems, gathering information, analyzing data, and drawing conclusions. One such learning model is Discovery Learning. This study aims to improve students’ cognitive abilities regarding the topic of vibrations through the application of the Discovery Learning model. The research design used is a pre-experimental study with a one-group pretest-posttest design. The study was conducted with 26 eighth-grade students at SMP Negeri 4 Kairatu. Data collection was conducted using both test and non-test methods. The test instrument consisted of 10 multiple-choice questions and 5 essay questions administered during the pretest and posttest, while the non-test instrument consisted of Student Worksheets (LKPD) used to evaluate cognitive abilities during the learning process. The research results show that on the pre-test, all students (100%) were classified as failing, with an average achievement score of 13.60. After implementing the Discovery Learning model, the students’ average achievement score on the post-test increased to 87.47, classified as good. Analysis of cognitive abilities during the learning process revealed an average score of 82.5, classified as good. Additionally, the N-Gain test results showed an average score of 0.85, which falls into the high category. Thus, it can be concluded that the implementation of the Discovery Learning model is effective in improving students’ cognitive abilities regarding the topic of vibrations in the 8th-grade class at SMP Negeri 4 Kairatu.
