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

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.     

Respecting Respect: Exploring a great deal

For some people, respect is due to people of particular standing and involves formality and deference. For others, respect is based on regard and attention. This approach is essentially informal. This article explores young people's interpretations of respect and shows how an understanding of its theory and practice may enhance relationships between adults, especially those employed in the social professions, and young people. Two frameworks are employed to assist in exploring the issues involved; one is located in communication theory within educational contexts (Burbules, 1993) and the other in the politics of self-definition (Wilson, 1993). The discussion draws on three pieces of empirical research involving young people and professionals. The different interpretations of respect are shown to provide a means of understanding a source of conflict between professionals with positions of authority in young people's lives and the young people themselves.     

Hannah Arendt and Norwegian Muslim children’s schooling: in pursuit of democratic practices

The aim of this paper is to consider whether Hannah Arendt’s (1996) [Arendt, H. (1958/1998 Arendt, H. (1958/1998). Vita Activa. The Human Condition. Chicago: University of Chicago. [Google Scholar]). Vita Activa. The Human Condition. Chicago: University of Chicago] concept of ‘public space’ is a potentially useful and creative way of thinking about aspects of Muslim children’s experiences within the context of education. Following a terror attack in 2011, when 77 people were killed, the then Norwegian prime minister stated that ‘our answer to this violence is more openness and more democracy but not naivety’. Accordingly, this paper draws on data so as to put concepts drawn from Arendt to work. In so doing, we indicate possibilities for ‘more openness and more democracy’ where Norwegian children can have Islam as an important element within their lives in ways that avoid the charge of naivety.     

Enrollment projection models for institutional planning

This paper examines alternative techniques for projecting freshman enrollment in specific academic departments. Departmental enrollment projections provided by four different projection models are compared to actual departmental enrollments at a selected institution. Two of the models use only historical data, while the other two models are sensitized to current developments as indicated by the expressed major choices of prospective freshmen. The use of discriminant analysis to establish differential enrollment probabilities is also explored.Although different models do a better job for different curricular departments, the smallest mean squared error across all departments was obtained with the simplest projection technique. The use of the preliminary major choice of prospective freshmen did not improve departmental projections, and the student characteristics explored in this study did not differentiate enrolled from non-enrolled students adequately enough to improve enrollment projection accuracy.Based on the results obtained at this one institution, therefore, it would appear that simple and straightforward projection models can be as useful as complex and sophisticated models.This is an expanded version of an earlier paper read at the 1971 Association of Institutional Research Forum in Denver, Colorado.     

Students' estimates of knowledge gained as measures of the quality of teacher education

One set of measures of the quality of courses for the preparation of science teachers stems from the perceptions exit students have of their knowledge with respect to that teaching. The Discipline Review of Teacher Education in Mathematics and Science surveyed these students late in 1988 on three broad types of knowledge-science content knowledge, curriculum knowledge, and pedagogical knowledge. Some of these findings of the Review are described. In addition, the base for developing items to measure these three types of knowledge is discussed in this paper. The variety in the data that emerged is also presented and the consistency of the findings with other measures of quality is described. Specialisations: science and technology curriculum, environmental education, educational disadvantage. Specialisations: research and evaluation in teacher education, technical and further education and total quality management. Specialisations: research in educational systems.     

Evaluation of the benefits of laboratory research and information services

The authors examine the problems of ex-post evaluation of the benefits deriving from services provided by Government Laboratories. They concentrate on the difficulties of conducting meaningful ex-post studies since they feel that too many claims are made on the basis of inadequate, incomplete economic assessments using data that would not be substantiated if probed deeply. Their views are based on a review of nine years' practical evaluation experience.The paper defines three ways in which services/information sources can link up with intended recipients, and discusses the practical problems associated with assessing the impact of services in each case. These problems range from sampling errors and sample bias in questionnaire approaches, to limited respondent knowledge and perspective. Critical probing can overcome these difficulties in some, though not all, instances, since there are issues of principle that prohibit unique attribution of benefits to specific initiatives in many ex-post analyses. The use of cost recovery as a proxy measure of worth is reviewed.The authors point out that ex-ante appraisal of profits is not subject to the same constraints and avoids many of the pitfalls of ex-post evaluation.
