摘要:In this study, science (physics, chemistry and biology) undergraduate students’ perceptions about the roles of student and lecturer, nature of knowledge, and student’s task in examination was investigated. Besides, comparison of students’ perceptions was made in these four points with four class levels. A version of Perry Model developed by Finster was used in this study. This model shows how students develop from a simplistic stance on the nature of knowledge to one which is more pluralistic and contextual. The results showed that university learning environment positively effected the science undergraduate students’ perceptions about role of lecturer, taking responsibility for their own learning, autonomous learning, and self expression. In addition, obtained findings can be a guide for redesign of learning environments in undergraduate science education.
