This study investigated university students?? perceptions of their institutions?? learning environments, and related those perceptions to students?? academic aspirations and satisfaction with their universities. A sample of 12,423 juniors at 42 universities in Taiwan was used to confirm the validity and reliability of the instrument: CUEI-S. The study revealed diversity of students?? perceptions among specific aspects of the learning environment. Students responded more positively for student cohesion, library resources and administrative support, but less positively for student-faculty relations, student services, enhancement of their language abilities and emotional development. The majority of students had low academic aspirations but felt satisfied with their universities. The learning environment on campus was shown to play an important role both in students?? academic aspirations and in their general satisfaction, whether the individual student or the university was used as the unit of analysis. The relationship between faculty and students is the aspect that was most strongly associated with students?? academic aspirations. On the other hand, both adequate library resources and university support for student services were the key correlates of students?? general satisfaction at the individual student level. By identifying important relationships among variables, this study suggests initiatives for improving the learning environment at higher education institutions.  相似文献

The purpose of this study is to examine the relationship between student self-concept and achievement in science in Taiwan based on the big-fish-little-pond effect (BFLPE) model using the Trends in International Mathematics and Science Study (TIMSS) 2003 and 2007 databases. Hierarchical linear modeling was used to examine the effects of the student-level and school-level science achievement on student self-concept of learning science. The results indicated that student science achievement was positively associated with individual self-concept of learning science in both TIMSS 2003 and 2007. On the contrary, while school-average science achievement was negatively related to student self-concept in TIMSS 2003, it had no statistically significant relationship with student self-concept in TIMSS 2007. The findings of this study shed light on possible explanations for the existence of BFLPE and also lead to an international discussion on the generalization of BFLPE.  相似文献
