A prototype Semantic Web-based digital content exchange for schools in Singapore

Singapore has many large and educationally valuable digital collections and is planning the development of many more. These digital collections contain historical, cultural and scientific multimedia objects, along with learning objects. At present, school teachers and pupils find it hard to locate many of these resources using traditional search engines. This paper describes a research investigation into the design and subsequent development of a prototype digital resource discovery portal (Digital Content Exchange) based on Semantic Web technologies, and explores some of the educational issues raised. The research project explored how the features of the Semantic Web might offer valuable additional educational benefits and affordances beyond that of those based on existing information retrieval technologies.

‘[We're on the right track,baby], we were born this way’! Exploring sports participation in Norway

Based on quantitative data from the Norwegian Statistisk Sentralbyrå (Statistics Norway) study of Mosjon, Friluftsliv og Kulturaktiviteter, this paper explores trends in Norwegians' participation in sports, with a focus on young people. Norway boasts particularly high levels of sports participation as well as sports club membership and young Norwegians are the quintessential sporting omnivores. Among other things, the Statistics Norway study reveals substantial increases in participation (among young people and females especially) during the period 1997–2007, a shift in the peak of participation to the late teenage years, a relatively high level of lifelong participants, a re-bound effect in the post-child rearing years and a growth in lifestyle sports. Young Norwegians grow up in a socio-economic context of relative equality between the sexes and high standards of living. An abundance of natural and artificial outdoor and indoor sporting facilities alongside a well-established voluntary sports club sector and an elementary school system that emphasizes physical exercise and recreation, as well as high levels of parental involvement, add to the favourable socio-economic conditions to create seemingly optimal circumstances for sports participation. All these reinforce the sporting and physical recreation cultures deeply embedded in Norwegian society and embodied by the very many middle-class parents in a country which, for the time being at least, remains relatively young in demographic terms. In terms of lessons to be learned for policy towards sports and physical education beyond Norway, there may be grounds for some optimism around parental involvement in children's sport as well as the potential appeal of lifestyle sports. That said, it is likely to be the greater socio-economic equalities in Scandinavian countries such as Norway that make them unrealistic benchmarks for sports participation elsewhere.     

Determinants of expected vs. actual match outcome: an examination of the German Bundesliga

Within society, there are many publications regarding expectations of firm performance. These include analysis, industry insiders and ranking service. Within sports, bookmakers provide betting odds that reflect the expected outcome of matches and are determined by several factors. The purpose of this study is to analyse the determinants of expected match outcome (i.e. betting odds) and compare them to those of actual match outcome. Data from the 2010/2011 season of the German Bundesliga (soccer) are made available that are combined with betting odds for each match. Regression results show that several factors, such as difference in standing between team and opponent, difference in competitions played, difference in points earned over the last five matches, differences in standing last season and home advantage significantly influence expected match outcome. On the contrary, actual match outcome is only determined by the latter two factors.     

“Ah,I know why…”: children developing understandings through engaging with a picture book

This article describes part of a study that explored the responses of nine‐ and ten‐year‐old children during a picturebook read aloud in a small group setting in a New Zealand classroom. The read aloud was interactive, where the participants were encouraged to respond to the book and to each other throughout the session. The authors created a framework for analysing the responses, adapting the model of Lawrence Sipe (2008) with its five categories of literary understanding, by expanding on the analytical category to enable a finer analysis of the responses. This article discusses the children's depth of thinking and the understandings they developed as they engaged with the read aloud. It also describes how the adapted framework allowed a closer analysis of these understandings, including the way the elements of art used in the illustrations contributed to the children's ideas. The findings suggest ways picturebooks can be used to promote children's thinking and how teachers can guide discussion about a complex text. Implications for use of the framework in further research are discussed.     

The Grass Isn’t Always Greener: Perceptions of and Performance on Open-Note Exams

Undergraduate biology education is often viewed as being focused on memorization rather than development of students’ critical-thinking abilities. We speculated that open-note testing would be an easily implemented change that would emphasize higher-order thinking. As open-note testing is not commonly used in the biological sciences and the literature on its effects in biology education is sparse, we performed a comprehensive analysis of this intervention on a primary literature–based exam across three large-enrollment laboratory courses. Although students believed open-note testing would impact exam scores, we found no effect on performance, either overall or on questions of nearly all Bloom’s levels. Open-note testing also produced no advantage when examined under a variety of parameters, including research experience, grade point average, course grade, prior exposure to primary literature–focused laboratory courses, or gender. Interestingly, we did observe small differences in open- and closed-note exam performance and perception for students who experienced open-note exams for an entire quarter. This implies that student preparation or in-test behavior can be altered by exposure to open-note testing conditions in a single course and that ­increased experience may be necessary to truly understand the impact of this intervention.     

Adolescents and Movie Ratings: Is Psychological Reactance a Theoretical Explanation for the Forbidden Fruit Effect?

Adolescents were recruited to participate in an experiment to assess whether psychological reactance can provide a theoretical explanation for the forbidden fruit effect in the context of movie rating restrictions. In addition to examining if movie ratings served as antecedents to freedom threat perceptions, we investigated the role authoritarian parents had on freedom threat perception and reactance arousal. Results indicated that a movie with an NC-17 rating was perceived as a stronger freedom threat than R and PG-13 rated movies. Interestingly, adolescents who perceived their parents to be authoritarian were less likely to view movie ratings as a freedom threat. As expected, freedom threat perceptions were positively associated with psychological reactance. Reactance, in turn, was positively associated with both first and third person attitudes. The results are discussed with an emphasis on the theoretical and practical implications of the findings.
