Different Disciplines Require Different Motivations for Student Success     

Rosanna Breen  Roger Lindsay 《Research in higher education》2002,43(6):693-725

This article reports an investigation of undergraduate motivation to learn. A Likert-type rating scale measure of motivation incorporated the general motivational dimensions identified by previous investigators, as well as a systematic theoretical framework that is more novel, and attempts to acknowledge the role of discipline-specific factors in motivation to learn. The motivation questionnaire was evaluated by measuring its success in explaining the academic achievement of biology, history, computing, planning, anthropology, geology, food science and nutrition, and education students (n = 380) in standard university assessments. The findings reveal that student performance is better explained by within- than across-discipline indexes of motivation, probably because some types of motivation lead to success in some disciplines but failure in others. Furthermore, items based on the theoretical framework developed to underpin the questionnaire (which distinguishes outcome from process incentives) were also found to explain more variation in student performance than general motivation items. Some practical implications of the findings are considered.  相似文献

Factors affecting the career progress of academic accountants in Australia: Cross-institutional and gender perspectives     

Nava Subramaniam 《Higher Education》2003,46(4):507-542

Since the late 1980s, Australian highereducation has undergone significant reforms andpolicy changes based on economic rationalismand modernisation of management. This paperexamines the outcomes of the reform processesbased on the career attributes, status andperceptions of work environment of academicaccountants in Australian universities.Similarities and differences between academicaccountants are explored fromcross-institutional and gender perspectives.The data provide insight into a number ofsystemic inequalities between the older andmore established universities and the neweruniversities. In specific, across-institutional analysis based on fouruniversity types: Sandstones/Redbricks,Gumtrees, Unitechs and New (Marginson 1999)indicates that academic accountants in Newuniversities employ a much lower proportion ofstaff with PhD qualification, a weakerpublication profile, and perceive greaterbarriers for conducting research in terms of ashortage of research mentors, colleagues withresearch experience, and post-graduatestudents. Further, the commitment to flexiblelearning and delivery strategies iscomparatively stronger in Unitechs, and posesadditional demands on accounting academics'overall workload. Perceptions of gender-baseddiscrimination by female academic accountantsare generally stronger than their malecounterparts, particularly, in Newuniversities. These results raise severalissues for academic accountants at both theinstitutional and individual level in terms ofequal employment opportunities, management ofresearch programmes, development of teachingstrategies and individual time management.  相似文献

校阅在CAT与FIT中对受测者行为表现与状态焦虑水平的影响     

陈燕  胡洁 《考试研究》2007,(1)

校阅(review)对CAT中受测者心理影响的研究有利于CAT的推广应用。J.Oleat等研究者在CAT(computerizedadaptivetest,计算机自适应性测验)与FIT(fixed-itemtest,固定项目测验)中,将校阅(review)对受测者行为表现与状态焦虑水平的影响作了比较研究。实验结果表明,在允许校阅的环境中,受测者正确反应与被估计的能力水平显著增加,并且状态焦虑水平下降。本文对J.Oleat等研究者的主要研究成果进行了详细的评述,并进一步探讨了在CAT中增设校阅(review)环境的重要性和可能性。  相似文献
