Exploring and testing cluster analysis

Academic deans annually negotiate for a fair share of university resources. Without quantitative accreditation standards to serve as minimum guidelines, the competition is more difficult. Peer institution comparison, derived from the analysis of quantitative data on resource and productivity variables, assists by providing less biased justification for budget requests. In this study, data from a national study of doctoral-granting teacher education programs was used for a factor analysis of key resource and productivity variables. Seven alternative cluster analysis methods were used and compared. Three follow-up procedures (analysis of variance, discriminant analysis, and classification analysis) tested the cluster analysis results to verify the differences between clusters and their internal homogeneity on three different cluster solutions. The classification analysis showed that 88.2% of the 76 programs were correctly classified on the five-cluster solution produced using Ward's minimum variance method. The practical use of such data suggests that Cattell's pattern of profile similarly is a useful beginning to compare programs on factor scores; following that, raw data on each key variable might be used to prepare individual program profiles for more specific comparison.     

The Catholic school advantage and common school effect examined: a comparison between Muslim immigrant and native pupils in Flanders

This study investigates the impact of Catholic schooling on academic achievement of native Belgian and Muslim immigrant pupils. The distinctive characteristics of Catholic schools in Belgium (Flanders) form an exceptionally suitable context to study this. Multilevel latent growth curve analyses are conducted with data from approximately 5,000 pupils across 200 primary schools. No support was found for the Catholic school advantage hypothesis as the overall achievement growth for math and reading was not significantly better in Catholic schools than in public schools. Likewise, no evidence was found for the so-called “common school effect” hypothesis: The learning growth of Muslim pupils was not significantly better in Catholic schools. In fact, the initial achievement gap was found to be higher in Catholic schools than in public schools. Implications of these findings are discussed.     

Job satisfaction of University academics: Perspectives from Uganda

Although several studies in the affluent world have examined the job satisfaction and dissatisfaction of lecturers in higher education, little is known about academic job satisfaction in the low-resource countries. This study probes those factors contributing to academic satisfaction and dissatisfaction in higher education in the developing world. Using a sample of 182 respondents drawn from two universities in Uganda, this analysis reports that the factors most prevalent in the prediction of dons’ satisfaction relate to co-worker behaviour, supervision and intrinsic facets of teaching. Analogously, the stimuli that create academic dissatisfaction are largely extrinsic (contextual) factors with respect to facets of remuneration, governance, research, promotion, and working environment. This article discusses these findings in the light of Herzberg’s dichotomy and concludes that any given factor be it intrinsic or extrinsic can either evoke academic satisfaction or induce dissatisfaction. The present analysis finds that while age, rank, and tenure significantly predict academic job satisfaction, no evidence is adduced to support a gender influence on dons’ job satisfaction. Implications for Ugandan academics’ job satisfaction are formulated, recommendations made, and a further research agenda proposed.     

Writing centre tutoring sessions: addressing students’ concerns

The guiding principle behind university writing centres is to focus on the process of writing rather than the finished product, prioritising higher order concerns related to organisation and argumentation of texts rather than lower order concerns of grammar and punctuation. Using survey-based data, this paper examines students’ concerns regarding written texts in English and analyses whether there is a correlation between students’ and peer-tutors’ perceptions of help received/provided in the writing centre at Nanyang Technological University. The aggregate findings show that there is a significant correlation between their perceptions but a further sub-analysis that pairs individual student and peer-tutor responses reveals that there are discrepancies between their perceptions of the type of help received and provided. These findings not only reveal the type of feedback students prefer, whether global or local, but also whether there is a good fit between student needs and tutoring approach based on students’ nationality and English proficiency.     

Some interrelationships between constructivist models of learning and current neurobiological theory,with implications for science education

Recent advances in the neurosciences have begun to elucidate how some fundamental mechanisms of nervous system activity can explain human information processing and the acquisition of knowledge. Some of these findings are consistent with a cognitive view of constructivist models of learning and provide additional theoretical support for constructivist applications to science education reform. Current thought at the interface between neurocognitive research and constructivist philosophy is summarized here and discussed in a context of implications for scientific epistemology and conceptual change processes in science education.     

More than meets the eye: patterns and shifts in middle school mathematics teachers’ descriptions of models

Modeling is a major topic of interest in mathematics education. However, the field’s definition of models is diverse. Less is known about what teachers identify as mathematical models, even though it is teachers who ultimately enact modeling activities in the classroom. In this study, we asked nine middle school teachers with a variety of academic backgrounds and teaching experience to collect data related to one familiar physical phenomenon, cooling liquid. We then asked each participant to construct a model of that phenomenon, describe why it was a model, and identify whether a variety of artifacts representing the phenomenon also counted as models during a semi-structured interview. We sought to identify: what do mathematics teachers attend to when describing what constitutes a model? And, how do their attentions shift as they engage in different activities related to models? Using content analysis, we documented what features and purposes teachers attended to when describing a mathematical model. When constructing their own model, they focused on the visual form of the model and what quantitative information it should include. When deciding whether particular representational artifacts constituted models, they focused on how the representations reflected the system under study, and what purposes those representations could serve in further understanding that system. These findings suggest teachers may have multiple understandings of models, which are active at different times and reflect different perspectives. This has implications for research, teacher education, and professional development.
