Comparative study of learning achievement on the online asynchronous learning course in engineering metallurgy between individual-learning and group-learning

—In this study, authors describe the construction of Interactive Multimedia Computer Instruction Package (IMMCIP) on web for online asynchronous learning on engineering metallurgy course. The efficiency evaluation and comparative study of the learning were achieved between individual learning and group learning. The research tools were constructed an IMMCIP on Web, which included introduction to engineering metallurgy, crystal structure, deformation mechanism, phase diagram, Fe C‐diagram, heat treatment process, ferrous metals, non-ferrous metals, corrosion in metals and powder metallurgy. The samples were 30 undergraduate students in engineering metallurgy course in Department of Production Technology Education, Faculty of Industrial Education and Technology, King Mongkut’s University of Technology Thonburi, Thailand. The samples were divided into three groups: one computer per student, one computer per two students, and one computer per three students, which are 11, 10 and 9 students respectively. The results revealed that the efficiency of an IMMCIP on Web was higher than that the criteria set. Results were analyzed on pre‐test and post‐test of every group, which were achieved significantly high score. The results found that learning achievement of one computer per three-student group was different from others and had the higher learning achievement with significantly.
