This study is the development of collaborative project based learning model on computer network for developing critical thinking and team working of high vocational certificate students. There were 5 steps in research procedure: 1) studying the current situation, problems, and suggestions in teaching and learning management in Business computer major from the Institute of Vocational Education: Northeastern Region 3; 2) analysis and synthesis; 3) model creation; 4) model experiment; and 5) certified evaluation of the model. The results of this research were follows:There were 3 aspects of collaborative project based learning model on computer network for developing critical thinking and team working of high vocational certificate students: 1) there were 6 model configurations; 2) there were 7 steps in learning and teaching management; 3) there were 6 modules in model construction and configuration on lessons according to computer network. The efficacy of 5 lessons in computer network was evaluated by the expert at 87.06/84.78 and the effectiveness index was 0.6447. The comparison result of the learning achievement and critical thinking skill before and after learning through lessons on computer network revealed that students’ learning achievement and critical thinking skill before and after learning through lessons on computer network were significantly different at .05It could be interpreted that students got higher knowledge and their critical thinking skill was improved. The comparison result of critical thinking skill, team working, and learning achievement after the lessons on computer network was applied found that students who studied via the lessons was significantly different from the students who studied the traditional learning style at.05. The students who studied via the lessons on computer network performed much better that the students who studied with the traditional learning style. Students were satisfied with the developed lessons constructed in computer network at high level, and they were ...
