This study investigates students' achievement goal orientation in relation to their attitudes toward group work and perceptions of group members' collaboration behaviors. A total of 48 (33 males and 15 females) 4th year Instructional Technology Department students were taking Design, Development and Evaluation of Educational Software course at Middle East Technical University in the Spring term of the year 2003 formed the sample of this study. The study lasted 14 weeks. During this period the students worked in groups and developed 3D learning environments by using rapid prototyping approach and Active World. 3.3[C]. At the end of the semester a four-part survey questionnaire was given to students to collect data on background, achievement goal orientations, attitudes toward group work and perceptions of their group members' performances in terms of effective collaborative rubric. The data were analyzed by descriptive and inferential statistics. The correlation analysis showed no significant relationship between attitudes toward group work and profiles of achievement goal orientations. However there is a correlation between attitudes toward group work and how subjects perceive their team members' collaboration in regard to contribution to task, discussing and listening, and team functioning behaviors. Significant correlations were found between collaboration on contribution to task, discussing and listening, and team functioning behaviors. The results indicated that there was a significant relationship between mastery and ego orientations, negative relationship between GPA and work avoidant orientation. Finally males were significantly more work-avoidant than females. (Contains 3 tables.)
