摘要：Recently, leaders of business and industry world generally require workers who are capable of working collaboratively to make their business a success. Unfortunately, various studies show that most high school students do not have the capacity to work collaboratively in solid teamwork. For this reason, high schools must develop the teamwork capacity of their students during the learning process. The present study was designed to examine the effectiveness of a collaborative teamwork learning model to improve the teamwork capacity of high school students. It was an experimental study with one group pretest-posttest design. The experiment was carried out in three high schools. They were SMA Negeri 1 Pontianak, SMA Negeri 1 Mempawah, and SMA Negeri 5 Singkawang. There were four aspects of the students’ teamwork capacity to develop. These aspects were sharing, collaboration, paying attention to the rights and welfare of others, and caring for others. The results of the study showed that the collaborative teamwork learning model was effective to improve the teamwork capacity of the students in three high schools. All of the investigated aspects got improved. They were categorized “high”, except the aspect of ‘paying attention to the rights and welfare of others’. It was classified “medium”.
