DISSERTATION RESEARCH: PART 2, THE QUANTITATIVE DISSERTATION: FORM AND SUBSTANCE

This is the second in a three‐part series of papers concerning dissertation research. In this paper, the elements of quantitative dissertations are identified for analysis and subsequent discussion. Dissertation research should provide the researcher the opportunity to become another example of the generative, creative, and inventive capacity of mankind to be liberated for a period of time from the immediate in order to extend his or her own thoughts forward toward whatever future may be permitted. Dissertation research should provide the reader an opportunity to extend and expand his realm of thought apart from an imposed or artificial conformity to form.     

Multiple True-False Items: A Study of Interitem Correlations, Scoring Alternatives, and Reliability Estimation

Intercorrelations among multiple true-false items were examined to determine to what extent each true-false option can be treated as independent. Results from 157 health science students and 170 medical students showed that correlations between true-false options associated with the same stem were from 2.6 to 7.0 times larger than those from different stems. This suggests that results from previous research indicating that each true-false option could be treated as an independent item cannot be generalized to other tests and examinee populations without supporting evidence. Four scoring methods were explored which varied chance success levels and scoring for partial knowledge. The results showed that scoring methods incorporating partial knowledge were more reliable and possessed greater concurrent and predictive validity than those minimizing chance success. Methods for computing reliability estimates were compared and suggestions were offered regarding practical use     

Faculty dynamation: Guided empowerment

Dynamation is the integrative process whereby the sum total of all learning, knowledge, experiences, and feelings are brought to bear on productive, creative action and problem solving. In this paper, we describe some of the benefits of dynamation, outline a general approach to it-including the importance of friendship (the core of the empowerment process)- and explain several key incentives that will encourage faculty, through dynamation, to engage in growth activities. Throughout the article we discuss ten techniques developers can use. Our focus is on informal facilitator-enhanced (guided) empowerment. That is, we look at growth that is likely to result when developers work with faculty with the goal of growth, change, and development.Richard L.

Costs and economies of scale in Turkey's postsecondary vocational schools

The study reported in this paper examines the institutional cost structures of the postsecondary vocational education system in Turkey. The study uses a single-output quadratic cost function to analyze 65 individual vocational schools located within the 28 existing universities. Appropriate controls for institutional quality, discretionary allocation of staffing resources, the degree of technical instruction in the cirriculum, and regional variation are also included. Both average and marginal costs for each school are estimated over relevant ranges of student enrollments for determing prospective degrees of economies of scale. The findings should help policy makers in Turkey determine which vocational schools can reap efficiencies by an expansion (or contraction) of their student enrollments.     

The Australian Science Teacher: A Typology of Teacher–Student Interpersonal Behaviour in Australian Science Classes

This study reports the first development in Australia of science teacher typologies of teacher–student interpersonal behaviour. Students' perceptions of teacher–student interpersonal behaviour were measured using the Questionnaire on Teacher Interaction (QTI). Earlier work with the QTI in The Netherlands has revealed eight different interpersonal styles, which were later confirmed with an American sample of secondary school teachers. The present study investigated the extent to which typologies found in earlier studies also apply to a sample of Australian secondary school science teachers. Data were first checked to examine whether the eight profiles found in The Netherlands and the USA were also present in the Australian data. A cluster analysis using various clustering methods and procedures was used to determine Australian typologies and compare these with earlier Dutch findings. Results of the cluster analyses were verified by analyses of variance, by plotting QTI scale scores graphically, and by presenting a set of sector graphics to two independent researchers and having them sort these into different profiles as found in the statistical analyses. The resultant typologies and implications for professional development and research are presented.     

DETERMINANTS OF RESEARCH PRODUCTIVITY IN HIGHER EDUCATION

As research expenditures have risen and assources of research funding have changed, an increasedemphasis on research performance has developed in U.S.research universities. Although much of the historical debate has centered around the individualattributes of faculty, several recent studies have begunto focus on the effect of program or organizationalfactors as powerful attributes for enhancing suchproductivity. This paper extends the findings of these recentstudies by examining the relationship between academicresearch productivity and institutional factors from themost recent National Research Council data on the nation's research universities and theirprograms in the four broad fields of the biologicalsciences, engineering, the physical sciences andmathematics, and the social and behavioral sciences. Several findings are recommended forinstitutional policymakers.
