Some of the key issues in pedagogy are the way of students' peer learning, collaboration, and team work at school. Friendship quality is essential for academic achievement by peer learning and team work. In line with that, the aim of the present study is to examine the associations between variables that are positive perception, deliberative belief and friendship quality utilizing structural equation modeling. The sample of research consists of 302 college student from Taiwan by random multistage cluster sampling method. Three main hypotheses are tested: (a) positive perception predicts students' deliberative belief; (b) deliberative belief predicts friendship quality; and (c) positive perception predicts friendship quality. The SEM model has good conditions in terms of fitness indices and fitness data. The results reveal that positive perception is significantly predictive of deliberative belief. Furthermore, deliberative belief is a strong predictor of friendship quality. The quantitative findings recommend that promoting students' positive perception and applying deliberative pedagogy might improve their friendship quality.
