協同合作是服務-學習的特質之一,本研究從團體行為改變技術的角度,探討服務-學習對於班級凝聚力的提升有無明顯作用;為此,本研究於100學年度第一學期,針對實施服務-學習課程的7個班級共359位學生,應用問卷調查法於課程前後各施測一次,有效問卷共計325人,量表的信度前後測皆為 .837。本研究發現,參與此項課程的班級在團體凝聚力的三個指標,亦即「吸引力」、「團結一致」以及「協同合作」的得分上皆有明顯的進步;若以另一個凝聚力的指標──「社會關係密度」觀之,也呈現相同的現象;顯示協同合作式的服務-學習課程的參與,對班級的凝聚力的提升是有顯著的效果。其次,從社會關係結構圖加以觀察,七個班級內部的人際關係結構,也有明顯的改變,置身於團體以外「孤獨型」的學生人數減少,本不相連結的小團體也與其他團體建立關係的連結,這些都顯示參與服務-學習的確有其效益存在。
Collaboration is one of the characteristics of service-learning. The purpose of this research is to investigate if class cohesion has been significantly improved through one-semester of service-leaning activities. Three hundred and fifty nine students are surveyed with questionnaires before and after the activities. Three hundred and twenty five questionnaires are effective and the reliabilities reach .837. This research finds that either group attraction or solidarity and collaboration of these classes have significantly improved. The increase in social relationship density of these classes also proves the similar phenomenon. All of these findings show that exercising collaboration type of service-leaning curriculums has positive effects on improving class cohesion. In addition, this research also finds that the personal relationship structure of these seven classes has changed dramatically too. Isolators of each class decrease dramatically and independent subgroups have been connected after the service-leaning curriculum. This paper proves that findings show that service-leaning curriculum has positive function in education.
