Development of a Collaborative Active Learning Management Platform in an English Communication Course for Education and Application with Undergraduate Students

Background and Aim: Thailand’s declining undergraduate English communication scores and continued teacher-centered EFL practices underscore the urgent need for innovation. This Research and Development study created a Collaborative Active Learning (CAL) management platform, designed with the ADDIE model to promote interactive, student-centered learning, strengthen 21st‑century skills, reduce language anxiety, and provide a scalable digital solution aligned with national policies and CEFR standards. The study aimed to: (1) develop and implement the CAL platform for the English Communication for Education course; (2) evaluate its efficiency using the 80/80 criterion; (3) determine its effectiveness index; (4) compare students’ achievement before and after use; and (5) examine expert and student feedback on the platform. Materials and Methods: This research was a research and development study. The sample consisted of 57 undergraduate students in the Faculty of Education, selected through cluster random sampling using classrooms as the sampling units. The research instruments included: 1) the developed CAL for the English Communication for Education Course; 2) a learning achievement test; 3) an expert evaluation form for the platform’s quality; and 4) a student satisfaction questionnaire. Data were analyzed using percentages, means, standard deviations, and t-tests. Results: The results showed that the developed platform achieved an efficiency of 81.08/83.97, exceeding the 80/80 standard, with an effectiveness index of 0.8241. Students’ post-test scores were significantly higher than their pre-test scores at the .05 level. Experts rated the platform’s quality as high, while students reported the highest level of satisfaction. The platform is practical for real-world implementation and effectively enhances learning for the English Communication for Education Course. Conclusion: This research and development (R&D) study developed a Collaborative Active Learning (CAL) management platform for the undergraduate English Communication for Education course using the ADDIE model. The platform significantly improved student achievement, reduced language anxiety, and received high levels of satisfaction from both experts and students. It provides a replicable, evidence-based approach to transforming EFL instruction and fostering 21st‑century skills in Thai higher education.
