Understanding the characteristics of effective professors: the student's perspective

Increasingly, higher education institutions are realising that higher education could be regarded as a business-like service industry and they are beginning to focus more on meeting or even exceeding the needs of their students. Recent research findings suggest that the factors that create student satisfaction with teaching (‘teaching satisfiers’) may be qualitatively differently from the factors that create dissatisfaction with teaching. Thus, this research uses the Kano methodology to reveal the characteristics of professors that students take for granted (‘Must-be factors’) and that have the potential to delight them (‘Excitement factors’). Kano questionnaires containing 19 attributes of effective professors taken from previous studies and focus group discussions were handed out in two marketing courses to 63 postgraduate students enrolled in a service marketing course. The Kano results corroborate previous US findings that revealed the importance of personality in general and support studies that stress the importance of professors creating rapport with their students in particular.     

Primary and secondary school choice among public and religious alternatives

In this paper we develop a conceptual framework for analyzing school choice decisions, evaluate past empirical research, and estimate an individual level model of choice using a unique data set. Previous empirical work modeling households' decisions to send their children to public or private schools frequently employed incomplete or aggregate data that precluded firm policy conclusions. The data employed here merges 1980 individual level census data with information about schools in New York. The results suggest that parents are sensitive to the relative quality of school offerings, the tuition of religious schools, characteristics of other students in each alternative, and socioeconomic characteristics of the family. The empirical findings contribute to our understanding of the existing school choice structure and provide insights concerning new school choice proposals.

Evaluating taught postgraduate awards from the student’s perspective

There is a need for a questionnaire designed specifically to evaluate taught postgraduate (TPg) awards for quality assurance or enhancement purposes. Comparison of undergraduate and TPg awards suggests that as the former have broadened their ambit to better nurture generic graduate attributes, TPg awards have concentrated on advanced specialised knowledge and skills. Those enrolling in TPg programmes are often mature part-time students working in a field associated with the subject studied. A set of interviews with TPg students revealed that they had clear expectations of the knowledge and skills they were expected to acquire from their studies and were able to comment critically on curriculum design. This made it clear that instruments designed for undergraduate degrees would not be suitable. Therefore, a TPg questionnaire was designed based on a model derived from a qualitative study, which adopted a grounded theory approach to collect views from 21 part-time TPg students from seven programmes offered by six institutions in Hong Kong. The conceptual model underpinning the questionnaire design was tested using structural equation modelling. As the results showed a good fit to the data, the validity of the questionnaire was confirmed. Use of the instrument in a routine quality assurance exercise across a university revealed that results from the questionnaire were highly diagnostic, so providing constructive feedback for curriculum reform.     

Employee Perceptions of Workplace Factors That Will Most Improve Their Performance

Training is often the performance improvement solution of choice, yet how often does the best training not yield performance improvement? There is a growing body of evidence that indicates that many times performance improvement can be achieved faster, cheaper, and better by altering factors in the workplace than by training. This article describes an activity designed to illustrate the importance of workplace factors in improving performance and a study that demonstrates its validity. Results of the study indicate that two-thirds of the participants believed the environmental factors of information, resources, and incentives needed improving in order to enable them to improve their own performance.     

Factors influencing the college choice decisions of graduate students

This paper examines the relative influence of factors affecting the college choice decisions of graduate students. It is based on a 1986 survey of 2,834 admitted students at a major research university, to which 38 percent of the sample responded. Factor analysis of ratings of importance of 31 college characteristics yielded dimensions upon which student decisions are based. These results were used to build five scales of importance and preference, which were then tested with other variables in a regression model in which the dependent variable was the decision to enroll or not to enroll at the surveying institution. The following were found to influence decisions: residency status, quality and other academic environment characteristics, work-related concerns, spouse considerations, financial aid, and the campus social environment.A paper presented at the Annual Forum of the Association for Institutional Research, New Orleans, May 29–June 1, 1994.     

Improving the quality of education through self-evaluation in Dutch secondary schools

In countries with a governance structure in which responsibility for the quality of education is shared between government and school boards, the past decades school self-evaluation has been stimulated as a way to encourage continuous quality improvement. However, working on the goals of quality assurance and school improvement at the same time is a challenge in general. To make a valuable contribution to both goals, the self-evaluation effort has to be of sufficient quality itself. In this article, we present a research-based framework for school self-evaluation (SSE) composed of both content and process factors that allows to evaluate the quality of self-evaluation in schools. We then used this model to evaluate the experiences in a comprehensive self-evaluation project that has been designed and used to help Dutch secondary schools promote the quality of student care. Our sample encompassed 79 Dutch secondary schools involved in this project. The findings show that the quality of SSE depends on the quality of the instruments (content) and process factors. However, to make a valuable contribution to school improvement and thereby the quality of education in The Netherlands more attention is needed for a balance between internal and external supervision and the role of school managers in the process of SSE.For future research more insight is needed in the challenges of meeting the content and process conditions of school self-evaluations, the governance and supervision issue at the level of schoolboards, the competence of change management in schools and the effects of SSE on the quality of education.

Learning science by doing science: an authentic science process-learning model in postsecondary education

Research on understanding the full extent that an authentic science research experience engages students in how scientists think and act is sparse. ‘Learning-science-by-doing-science’ (LSDS) is an emerging self-guided process-learning model in postsecondary science education. It offers authentic science research opportunities that drive students to think and act like scientists. This study investigates the LSDS approach as a potential model for science learning at postsecondary level and aims to answer a main research inquiry – what are the students’ and teaching staff’s perceptions of students’ learning gains and the quality of their learning experiences in an authentic research environment within the LSDS model? To answer this question, data were collected from the students, alumni, instructors, teaching assistants and the program director via questionnaires, focus groups and interviews. Students’ and staff’s lived experiences and their perceptions on their authentic research experiences within the LSDS model were used to articulate the key attributes and stages of the LSDS model. The outcomes of this study can be used to help other science programs implement similar authentic research process learning approaches in their own contexts.     

Public Transit and School Choice in Philadelphia: Exploring Spatial Equity and Social Exclusion

This article explores the importance of considering transportation mode when calculating commute time for a child’s school choice options. While proponents of school choice argue that students can attend any school that will provide them the best education, several have argued that commute time is as important for families as a school’s characteristics. However, research to date models commute time using either distance as a proxy or minutes driving. In Philadelphia, a context where most people use public transportation to work and school, the authors argue that commute time to school must be calculated using this mode of transit. Using geospatial network analyses, the authors create choice sets for each neighborhood public high school. They first calculate the commute time between each zoned public high school and each public high school choice in the city by driving and by using public transportation. These two sets of commute times are then evaluated for the differences. The authors then calculate choice sets based on the average commute time in the city based on both modes of transportation. Finally, they compare the choice sets for each service area for spatial equity of public school quality. Findings indicate that the commute times between driving and public transportation are statistically different. Furthermore, public school choice sets within Philadelphia are spatially equitable, although the overall school quality needs improvement. The article concludes with policy implications and recommendations for future research.     

Artificial neural network modeling of water quality of the Yangtze River system: a case study in reaches crossing the city of Chongqing

An effective approach for describing complicated water quality processes is very important for river water quality management. We built two artificial neural network （ANN） models, a feed-forward back-propagation （BP） model and a radial basis function （RBF） model, to simulate the water quality of the Yangtze and Jialing Rivers in reaches crossing the city of Chongqing, P. R. China. Our models used the historical monitoring data of biological oxygen demand, dissolved oxygen, ammonia, oil and volatile phenolic compounds. Comparison with the one-dimensional traditional water quality model suggest that both BP and RBF models are superior; their higher accuracy and better goodness-of-fit indicate that the ANN calculation of water quality agrees better with measurement. It is demonstrated that ANN modeling can be a tool for estimating the water quality of the Yangtze River. Of the two ANN models, the RBF model calculates with a smaller mean error, but a larger root mean square error. More effort to identify out the causes of these differences would help optimize the structures of neural network water-quality models.     

Parental Priorities in the Selection of International Schools

The issue of choice of schooling for their offspring is one which exercises many parents based in different parts of the world. For parents whose employment takes them away from their home country and whose children accompany them on such postings, the issue—while different from the experience of parents based solely within national systems—is no less important or complex. This paper investigates the issue of parental choice and priorities within the context of three international schools in Switzerland, where a study was undertaken to establish the basis on which parents had elected to send their children to one or other of the schools in question. Based on a survey model of questionnaires and follow-up interviews with parents, the research concludes that a major factor influencing parents is the perceived importance of an English-medium education. Interesting similarities in perceptions to emerge from the study are found amongst parents from the different schools and amongst parents of primary and secondary age children, while differences in perceived levels of importance clearly emerge between fathers and mothers, and between parents from different geographical backgrounds. The paper suggests some preliminary explanations for such differences, and highlights areas which could form the basis for further pieces of research in this growing and increasingly important context.
