Modeling the Etiology of Individual Differences in Early Reading Development: Evidence for Strong Genetic Influences

We explored the etiology of individual differences in reading development from post-kindergarten to post–4th grade by analyzing data from 487 twin pairs tested in Colorado. Data from three reading measures and one spelling measure were fit to biometric latent growth curve models, allowing us to extend previous behavioral genetic studies of the etiology of early reading development at specific time points. We found primarily genetic influences on individual differences at post–1st grade for all measures. Genetic influences on variance in growth rates were also found, with evidence of small, nonsignificant, shared environmental influences for two measures. We discuss our results, including their implications for educational policy.     

Using Video Games to Support Pre-Service Elementary Teachers Learning of Basic Physics Principles

The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with pre-service elementary teachers. To this end we explored the impact of using a game called Supercharged! on pre-service teachers’ understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! the control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference F(2,134) = 4.8, p < 0.05, η² = 0.59 between the control and experimental groups on the gains from pre-to-post assessment with an effect size of d = 0.72. However, while students in the experimental group performed better than their control group peers, they rated their knowledge of the topic lower than the control group (M _post-control = 3.0, M _{post-experiment} = 2.7), leading to further examination of their laboratory journals. Results of this study show that video games can lead to positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment. Additionally, this study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that video game designers should embed meta-cognitive activities such as reflective opportunities into educational video games to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.     

Establishing the critical elements that determine authentic assessment

This study sought to determine the critical elements of an authentic learning activity, design them into an applicable framework and then use this framework to guide the design, development and application of work-relevant assessment. Its purpose was to formulate an effective model of task design and assessment. The first phase of the study identified from the literature critical elements that determined assessment as being authentic, and presented these to practitioners and experts for feedback. In phase two, it codified the elements into a framework that was then applied to the redesign of assessments in an army course. Phase three involved student evaluation of the redesigned assessment activities. This led to further review and revision of elements in phase four. The study outcomes suggest that it is possible, by identifying and codifying individual elements, to determine the ways in which the authenticity of an individual assessment activity might be enhanced. The paper concludes with a literature update on the framework elements that lead to suggestions for further research.     

The attitudes and opinions of high school sports participants: an exploratory empirical examination

Sport scholars and public commentators have long held both positive and critical opinions about the influence of athletic involvement on participants and their perceptions of the social world. Yet for all of the strong claims and deeply held assumptions, relatively little empirical data or social scientific analysis have been available. This study begins to address this deficiency using new data from a nationally representative survey of American high school students. We compare sports participants and their peers in terms of concern for social problems, interracial contact and attitudes, views of gender roles and sex-based discrimination and political orientation. We find participants and non-participants differ very little in their social concern and views of gender roles and sex-based discrimination, while significant differences were found in levels of interracial contact, views on race relations and political orientation. In view of these findings, we make some general conclusions about the social influence of sport in the lives of American youth and how this topic may be further explored in subsequent work.     

Comment on ‘Performance analysis in football: A critical review and implications for future research’

Abstract

MacKenzie and Cushion (2013) recently reviewed performance analysis research in association football (soccer). Their critical review focused on several themes related to methodological approaches such as sample size, match context and operational definitions and the implications of research findings to professional practice. In this response letter, we comment on additional pragmatic concerns regarding these key themes as well as some of the difficulties commonly faced when conducting performance analysis research.     

‘Tough love and tears’: learning doctoral writing in the sciences

Contemporary changes to the doctorate mean student researchers are likely to be expected to write differently, write more and more often, and yet, despite a growing interest in doctoral education, we still know relatively little about the teaching and learning practices of students and supervisors vis-a-vis doctoral writing. This paper draws from a research study into the writing experiences of higher degree students and their supervisors in one science, health and technology-based university Faculty. The study used surveys, interviews and focus groups to collect information from students and supervisors about their experiences of doctoral writing and their perceptions about its development. By attending to the writing-related pedagogical practices of supervisors, this article explores how doctoral writing can be the stage for the playing out of tensions over changing roles and identities aggravated by contemporary pressures on doctoral education.
