THE DEVELOPMENT OF TEACHER TRAINING MATERIALS BASED ON COMMUNICATION SKILLS - INTEGRATED STEAM EDUCATION ACTIVITIES USING BLENDED LEARNING WITH OPEN EDUCATIONAL RESOURCES

Abstract

This research aimed to develop a teacher training package on STEAM education activities integrating communication skills through blended learning combined with open educational resources. The sample consisted of 130 teachers from Charuwattananukul School and 560 students in Grades 3 and 6 of the 2025 academic year. The participants were selected using purposive sampling. The developed training package comprised online lectures and assessment sessions, as well as on-site demonstrations and hands-on practice sessions, totaling 8–13 hours. The package evaluated by experts, the overall quality across six dimensions was at the highest level ( = 4.72, SD = 0.42) and met the effectiveness criterion of 80/80 (E₁ = 82.46, E₂ == 26.33, SD = 2.20) was significantly higher than their pre-training scores ( = 17.76, SD = 3.67) at the .05 level. Their ability to design STEAM-integrated learning activities after training ( = 15.63, SD = 2.37) was also significantly higher than before training ( = 2.54, SD = 2.26). Teachers’ overall satisfaction with the training was at a high level ( = 4.14, SD = 0.25). The findings revealed that the developed training package effectively responded to teachers’ needs and promoted their learning development. Regarding students’ key competencies, communication, problem-solving, life skills, and technology use were found to be at an excellent level for both Grade 3 (83.45%) and Grade 6 (89.32%) students. Furthermore, students’ satisfaction with the learning activities was high ( = 4.03 and 3.94, SD = 1.02 and 0.95, respectively). The results suggest that the trained teachers were capable of effectively designing and implementing activities to enhance students’ competencies.
