Problem-Based Learning Module for Programmable Logic Controller Learning Processes: An Effectiveness Study

Abstract

This study aims to analyze the effectiveness of the Problem-Based Learning Module (PBL-M) for the learning process of programmable logic controllers (PLC) in vocational high schools (VHS). The study used a pre-experimental design with a one-group pre-test-post-test design, involving a group of students from a VHS in Pariaman, West Sumatra, Indonesia. multiple choice tests were used as research instruments. The effectiveness was determined by analyzing the difference between pre-test and post-test scores using the paired sample t-test. Additionally, Cohen's D effect size analysis was conducted to measure the magnitude of the effect. The results showed a significant difference between the post-test scores and the pre-test scores, with the post-test scores being higher. Moreover, the effect size analysis indicated a large effect of using the PBL-M. These findings suggest that the PBL-M is effective in improving the PLC learning process in VHS.
