Use of Computer Modeling of Site-Directed Mutagenesis of a Selected Enzyme: A Class Activity for an Introductory Biochemistry Course     

Jones  Marjorie A.  Shoffner  Raymond  Friesen  Jon 《Journal of Science Education and Technology》2003,12(4):413-419

For an introductory undergraduate biochemistry class, we developed an interactive, out of classroom, team project that would allow students to gain a better understanding of protein structure and function. This project involved the use of the molecular visualization program RasMol and computer simulated site-directed mutagenesis of selected amino acids of the enzyme, Uroporphyrinogen decarboxylase. Survey data from students after completion of the project indicated that they had developed a more complete understanding of protein three-dimensional structure leading to functionality.  相似文献

Students working online for group projects: a test of an extended theory of planned behaviour model     

Eddie W. L. Cheng 《教育心理学》2017,37(9):1044-1056

This study examined an extended theory of planned behaviour (TPB) model that specified factors affecting students’ intentions to collaborate online for group work. Past behaviour, past experience and actual behavioural control were incorporated in the extended TPB model. The mediating roles of attitudes, subjective norms and perceived behavioural control were also examined. Data were collected from primary and secondary students in Hong Kong (N = 957). The partial least square approach to structural equation modelling was used to analyse the a priori hypothesised model. In general, the model fitted the data very well and the major relationships were found to be significant. The results indicated that past experience and actual behavioural control played individual roles in the model. Theoretical and practical implications are considered in this study.  相似文献   

Higher education experiences of elite student-para-athletes in the UK     

Natalie Campbell 《Journal of Further & Higher Education》2018,42(6):769-783

This article presents the narrative accounts of six elite student-para-athletes attending higher education full time in the UK. Whilst literature concerning the student-athlete population in the UK is growing, there is no research at present that brings to the fore the voices of student-athletes who represent their country in Paralympic sports. In addition, research concerning the experiences of higher education students with disabilities in the UK is heavily concerned with the experience of learning as opposed to the more nuanced experiences of ‘being’ a university student. Accounts concerning the lived experience of higher education were gathered via semi-structured interviews and analysed through a process of interpretative phenomenological analysis producing an intricate, intimate and personal theme for each participant. Analysed and presented as individual case studies, the research demonstrates the uniqueness of experience despite the existence of common and shared life environments. The accounts explore three life-worlds – university, elite sport and disability – and expose the difference in meaning-making by each participant to the identities of ‘athlete’, ‘student’ and ‘disabled’, specifically within the context of higher education. The accounts are presented as three themes that illuminate the contrast in experience: (1) university as a normative and positive experience; (2) university as a disappointing and hindering experience; and (3) university as an experience of personal salvation and purpose. Findings are mapped to the social-relational model of disability to better understand the relationship between individual perception, impairment and environment.  相似文献   

通过成本回收扩展高等教育:社会效率角度的理论研究     

钟宇平  陆根书 《高等教育研究》2001,(2)

对许多发展中国家而言 ,政府在扩展高等教育时常常面临很大的财政困难。结果 ,高等教育的入学机会常常规限于较低的水平 ,许多愿意承担一定成本的个体则被排斥在高等学校之外。本文应用局部均衡分析模型证明了成本回收是调动私人资源扩展高等教育进而缓解这种状况的有效方法  相似文献
