Transformative Education

Universities aspire to offer students a transformative experience, but rarely spell out the nature of this transformation. In this essay, L. A. Paul and John Quiggin frame the successful university education as transformative in the philosophical sense. They explain the way that a successful college education can be understood as generating an individual conceptual revolution, and thus, as a transformative experience. Education can create epistemically transformative change through the process of developing critical thinking skills, leading to conceptual replacement and the discovery of new intellectual frameworks. This epistemic transformation, if deep enough, scales up into a personal transformation. After explicating the nature and structure of transformative education, Paul and Quiggin show how understanding transformation in terms of personal change and awareness of unawareness clarifies the debate over its value.     

The association between homework and primary school children's academic achievement. International evidence from PIRLS and TIMSS

The association between time devoted to homework and children's academic achievement has long been an issue of great debate. A small number of mainly correlational studies have been conducted into this issue in a primary school setting, but have produced somewhat mixed results. In this paper we contribute to this literature by investigating the relationship between time spent upon homework and children's outcomes across 24 countries. By using a student fixed-effects approach, capturing differences in homework time amongst the same student across different school subjects, we argue that our results are likely to be subject to less confounding than much of the existing literature. We find little evidence that the amount of homework time primary school children are assigned is related to their academic achievement. This holds true across a large number of countries, survives various robustness tests and does not vary by gender or socio-economic status. We interpret this finding as suggesting that the homework assigned to primary school pupils may not be adequate to produce a positive association, and needs be improved if this time-consuming activity is ever going to bring benefits for children's academic achievement.     

Preface to special topic: surface modification, wetting, and biological interfaces (guest editors: john ralston and jingfang zhou)

This Special Topic section of Biomicrofluidics on "Surface Modification, Wetting, and Biological Interfaces," is discussed. The topic is very timely and one that is tremendously relevant to the microfluidics and nanofluidics community.     

Seasonal variation in physical activity among preschool children in a northern Canadian city

Little research has examined seasonal differences in physical activity (PA) levels among children. Proxy reports of PA were completed by 1,715 parents on their children in Edmonton, Alberta, Canada. Total PA (TPA) minutes were calculated, and each participant was classified as active, somewhat active, or inactive. Logistic regression models were conducted to examine associations between PA status and seasons. Significant seasonal differences were observed for TPA, weekday PA, weekend PA, and active play. Children were significantly more likely to be physically active in the summer and spring and somewhat physically active in the summer and fall, relative to winter Children living in cold climates are less likely to be physically active in the winter.     

Evolution and the nature of science: On the historical discord and its implications for education

Research in the teaching and learning of evolutionary biology has revealed persistent difficulties in student understanding of fundamental Darwinian concepts. These difficulties may be traced, in part, to science instruction that is based on philosophical conceptions of science that are no longer viewed as adequately characterizing the diverse nature of scientific practice, especially in evolutionary biology. This mismatch between evolution as practiced and the nature of science as perceived by researchers and educators has a long history extending back to the publication of Darwin's theory of natural selection. An examination of how this theory was received by the scientific community of the time may provide insight into some of the difficulties that students have today in learning these important biological concepts. The primary difficulties center around issues of metaphysics and scientific method, aspects of the nature of science too often ignored in science education. Our intent is not to offer a specific course of action to remedy the problems educators currently face, but rather to suggest an alternative path one might take to eventually reach a solution. That path, we argue, should include the use of broader models of science that incorporate these elements of scientific practice to structure teaching and education research in evolution. © 1998 John Wiley & Sons, Inc.

Parental assessment of peer play: Development and validation of the parent version of the Penn Interactive Peer Play Scale

The purpose of this investigation was to evaluate the construct validity of the parent version of the Penn Interactive Peer Play Scale (PIPPS) and to compare it with the teacher version. PIPPS were collected on 297 urban Head Start children. The Parent PIPPS replicated the three-factor solution found with the teacher version, supporting the following constructs of peer play: Play Interaction, Play Disruption, and Play Disconnection. Factor matching and canonical correlational analyses examining the relationship between the parent and teacher versions of the PIPPS revealed significant one-to-one matches between hypothesized like factors. Additionally, analyses of overlapping variance between versions indicated a significant degree of overlap. Implications of the findings for involvement of parents in the assessment process and research on the continuity and discontinuity between home and school environments for low-income, urban children were discussed.
