Social and Environmental Factors Associated With Preschoolers' Nonsedentary Physical Activity

The twofold purposes of the investigation were (a) to describe with direct observation data the physical activity behaviors and the accompanying social and environmental events of those behaviors for children in preschools and (b) to determine which contextual conditions were predictors of moderate to vigorous physical activity (MVPA) and nonsedentary physical activity (i.e., light activity + MVPA) for 3-, 4-, and 5-year-old children during their outdoor play. The results indicate that preschoolers' physical activity is characterized as sedentary in nature throughout their preschool day (i.e., 89% sedentary, 8% light activity, and 3% MVPA). During outdoor play periods, when children are most likely to be physically active, some contextual and social circumstances better predict their physical activity. Implications for policy makers, practitioners, and researchers are discussed.     

Sci-Tec: Evaluating a non-deficit model of in-service

The Sci-Tec project was based on an interactive, non-deficit model of in-service in which the fundamental principle was to value the expertise of all participants, and to encourage them to share that expertise with others. As part of the unfolding of the project, the participants also identified various areas of need as they arose, and these too became elements of the in-service agenda. The model has proved to be robust when applied in a wide range of schools, and with teachers who originally expressed widely varying degrees of confidence and interest in teaching primary science and technology. Specializations: primary science in-service education, curriculum leadership Specializations: in-service and pre-service primary science and technology     

Comparability of educational achievement and learning attitudes across nations

We estimated the invariance of educational achievement (EA) and learning attitudes (LA) measures across nations. A multi-group confirmatory factor analysis was used to estimate the invariance of educational achievement and learning attitudes across 55 nations (Programme for International Student Assessment [PISA] 2006 data, N?=?354,203). The constructs had the same meaning (factor loadings) but different scales (intercepts). Our conclusion is that comparisons of the relationships between educational achievement and learning attitudes across countries need to take into consideration two sources of variability: individual differences of students and group differences of educational systems. The lack of scalar invariance in EA and LA measures means that the relationships between EA and LA may have a different meaning at the level of nations and at the student level within countries. In other words, as PISA measures are not invariant in scalar sense, the comparisons across countries with nationally aggregated scores are not justified.     

Just do it? impact of a science apprenticeship program on high school students' understandings of the nature of science and scientific inquiry

The purpose of this study was to explicate the impact of an 8‐week science apprenticeship program on a group of high‐ability secondary students' understandings of the nature of science and scientific inquiry. Ten volunteers (Grades 10–11) completed a modified version of the Views of Nature of Science, Form B both before and after their apprenticeship to assess their conceptions of key aspects of the nature of science and scientific inquiry. Semistructured exit interviews provided an opportunity for students to describe the nature of their apprenticeship experiences and elaborate on their written questionnaire responses. Semistructured exit interviews were also conducted with the scientists who served as mentors for each of the science apprentices. For the most part, students held conceptions about the nature of science and scientific inquiry that were inconsistent with those described in current reforms. Participating science mentors held strong convictions that their apprentices had learned much about the scientific enterprise in the course of doing the science in their apprenticeship. Although most students did appear to gain knowledge about the processes of scientific inquiry, their conceptions about key aspects of the nature of science remained virtually unchanged. Epistemic demand and reflection appeared to be crucial components in the single case where a participant experienced substantial gains in her understandings of the nature of science and inquiry. © 2003 Wiley Periodicals, Inc.

Confronting prospective teachers' ideas of evolution and scientific inquiry using technology and inquiry‐based tasks

This study addresses the need for research in three areas: (1) teachers' understandings of scientific inquiry; (2) conceptual understandings of evolutionary processes; and (3) technology‐enhanced instruction using an inquiry approach. The purpose of this study was to determine in what ways The Galapagos Finches software–based materials created a context for learning and teaching about the nature of scientific knowledge and evolutionary concepts. The research used a design experiment in which researchers significantly modified a secondary science methods course. The multiple data sources included: audiotaped conversations of two focus pairs of participants as they interacted with the software; written pre‐ and posttests on concepts of natural selection of the 21 prospective teachers; written pre‐ and posttests on views of the nature of science; three e‐mail journal questions; and videotaped class discussions. Findings indicate that prospective teachers initially demonstrated alternative understandings of evolutionary concepts; there were uninformed understandings of the nature of scientific inquiry; there was little correlation between understandings and disciplines; and even the prospective teachers with research experience failed to understand the diverse methods used by scientists. Following the module there was evidence of enhanced understandings through metacognition, and the potential for interactive software to provide promising context for enhancing content understandings. © 2005 Wiley Periodicals, Inc.     

Relational Uncertainty as a Consequence of Partner Jealousy Expressions

The present study examines how the relational-uncertainty levels of individuals whose partners are jealous (i.e., “jealousy targets”) are predicted by how partners express jealousy. Students and community members completed a questionnaire where they recalled an instance when they were the recipients of their romantic partners' expression of jealousy. In general, jealousy-target relational uncertainty was positively predicted by a majority of negative and general behavioral partner jealousy expressions. However, positive partner jealousy expressions were not generally associated with jealousy-target relational uncertainty. Implications for the theoretical understanding of relational uncertainty and consequences of partner jealousy expression are discussed.     

Voices from South and North in dialogue: on diversity and education for the future

In this article texts by scholars from South Africa, Sweden and Great Britain are analysed. They contributed as invited speakers to a conference in Sweden in 2009 on changing societies, values, religions and education. Here a South–North dialogue on diversity and the future of education is constructed through the way their conference contributions are presented and analysed. Democracy and gender also appear as crucial themes. Out of the original 12 keynote contributions to the conference a selection is made, meaning that seven of them are focused on. What can be observed is (a) that the contributors from South Africa connect diversity and social justice; (b) that the gender researchers critically discuss the risks of the North imposing its theoretical framework on the South and search for ways out of that and (c) a preoccupation with a renewal of education recognising diversity but also looking for what could come beyond such an emphasis and form a common ground. The article constitutes an example of shared knowledge production where South and North meet. Conditions for that are critically reflected upon methodologically.
