Implementation of Virtual Laboratory with Problem Based Learning on Students Communication Skills
Abstract
This study is a pre-experimental study that aims to describe the communication skills of students before and after the implementation of virtual laboratories with problem-based learning, as well as to analyse the improvement in the communication skills of students at SMAN 14 Sinjai after participating in learning using virtual laboratories with problem-based learning. The data obtained in this study are quantitative data analysed using descriptive statistics and inferential statistics. The population and sample in this study consisted of 30 students selected using the saturated sampling technique. The instrument used to collect data was an essay test consisting of 15 questions developed in accordance with the indicators of students' communication skills, namely interpreting graphs, interpreting tables, interpreting images, changing the form of presentation, drawing conclusions, giving reasons, and explaining observation results. Based on the research data, it was found that the communication skills of Grade XI Unggul students at SMAN 14 Sinjai were in the moderate category with an average N-Gain value of 0.68. Meanwhile, the results of the significance test using the Wilcoxon signed-rank test showed a p-value of 0.001, which is smaller than 0.05. This indicates that the implementation of virtual laboratories with problem-based learning can improve students' communication skills.
