Abstract

The COVID-19 pandemic has changed various aspects of human life today, especially in education, which requires all elements of education to keep the classroom active, even though it is done online. For this reason, this study aims to determine the effect of applying scientific-based electronic natural science modules to improve learning outcomes in aspects of students' knowledge of vibration and wave material. The method used was an experimental method with a posttest-only control group design. The data collection instrument employed was multiple-choice test questions totaling 20 items. The sample in this study consisted of 30 students in the experimental class and 30 students in the control class. The data analysis utilized was in the Mann-Whitney U test to determine the differences in the mean posttest score between the experimental and control classes. The results revealed that the learning outcomes of the knowledge aspect in the experimental class were better than the control class. Based on the descriptive analysis results, the mean posttest score of the experimental class was higher than the control class, and the Mann-Whitney U test results were 0.000; thus, H 0 was rejected, and H 1 was accepted. In addition, the application of scientific-based electronic natural science modules improves the learning outcomes of students' knowledge aspects better.

Highlights

The COVID-19 pandemic has changed various aspects of human life today, especially in education, which requires all elements of education to maintain an active class, even though it is done online
Based on the research results and discussion, it can be concluded that there were differences in learning outcomes in aspects of natural science knowledge between groups of students taught with a scientific-based electronic natural science module and groups of students taught using conventional learning models in class VIII SMP in Surakarta in the academic year of 2020/2021
The differences could be seen from the mean score of learning outcomes from groups of students taught with a scientific-based electronic natural science module of 78.83, while the mean score of learning outcomes obtained by groups of students taught using conventional learning models was equal to 69.83

Summary

Introduction

The COVID-19 pandemic has changed various aspects of human life today, especially in education, which requires all elements of education to maintain an active class, even though it is done online. The COVID-19 pandemic urges distance education testing, which has never been done simultaneously before (Sun et al, 2020), for all elements of education, including students, teachers, and parents. The COVID-19 pandemic requires educational elements to maintain online learning. In the current face-to-face learning process, students do not understand the material presented in learning (Malyana, 2020). The conditions for implementing distance education are different from those during learning before the pandemic (Asmuni, 2020; Basar et al, 2021; Yoga Purandina & Astra Winaya, 2020). Teachers already own facilities, such as computers or laptops, they cannot develop an electronic book yet (Nakayama, M & Yamamoto, 2006; Szép, 2017)
