Effectiveness of Using E-learning at STEM-based Physics Learning to Improve Communication Skills of High School Students

Abstract

This study aims to determine the effectiveness of e-learning in STEM-based physics instruction on students' communication abilities. This research is a continuation of development research using the Allesi and Trollip model, which three experts have validated to make STEM-based e-learning to improve students' communication skills feasibly. The pre-experimental pretest-posttest design was used in this study's methodology. Thirty-one students from class XI MIPA Senior High Schools made up the sample for this study. The instrument used is a communication skill observation sheet with three observers to compare the impact before-after intervention, this study employed SPSS 25 to conduct a t-test and n-Gain. The results of the t-test and n-gain calculations show that STEM-based physics learning e-learning can significantly improve students' communication skills with an average n-gain score of 0.62 in the medium category. The highest increase was in oral communication (n-gain: 0.74), and the lowest was in student presentation skills (n-gain: 0.51). Furthermore, given the value of the t-count<t-table is 29.75<1.70, the analysis utilizing the t-test yields H1 being accepted so that the developed e-learning can be used as a medium for learning physics in the revolutionary era 4.0 in order to be able to face the demands of 21st-century learning.

The Analysis of Implementing STEM-based LKPD to Enhance Students’ Collaboration Skills in School

“…Implementing physics learning using the STEM approach can facilitate students in developing collaboration skills more optimally (Sury et al, 2022). The test results indicate a significant difference in improving collaboration skills between the experimental and control groups.…”
