The secret identity of a biology textbook: straight and naturally sexed

While education communities have well defined commitments to protect their learners from oppressive instructional materials, discourses of science education are often left unexamined. This analysis/critique employs queer theory as a perspective to look at how one widely used textbook in Ontario schools conceptualizes notions of gender and sexuality. Results indicate the use of discourses that promote exclusively heteronormative constructions of sexuality along with sex/gender binaries. Challenging such oppressive misconceptions of sex/gender and sexuality is discussed.     

On-demand publishing in the Humanities: project

This article describes the ‘On-Demand Publishing in the Humanities’ project, funded by JISC as part of the eLib programme, at Liverpool John Moores University. The principal aims of the project were to develop a ‘cheap and cheerful’ model for networking electronic texts, to develop a model agreement for the networking of copyright texts for use with publishers, and to shed light on the problems and benefits of on-demand publishing for all the stakeholders involved. The article sets out the project methods, describes the extent to which the aims of the project have been fulfilled, analyses the reactions of end-users to the materials, and attempts an assessment of the current viability of on-demand publishing as a means of supplying copyright texts to students.     

Scaling Performance Assessments: A Comparison of One-Parameter and Two-Parameter Partial Credit Models

In one study, parameters were estimated for constructed-response (CR) items in 8 tests from 4 operational testing programs using the l-parameter and 2- parameter partial credit (IPPC and 2PPC) models. Where multiple-choice (MC) items were present, these models were combined with the 1-parameter and 3-parameter logistic (IPL and 3PL) models, respectively. We found that item fit was better when the 2PPC model was used alone or with the 3PL model. Also, the slopes of the CR and MC items were found to differ substantially. In a second study, item parameter estimates produced using the IPL-IPPC and 3PL-2PPC model combinations were evaluated for fit to simulated data generated using true parameters known to fit one model combination or ttle other. The results suggested that the more flexible 3PL-2PPC model combination would produce better item fit than the IPL-1PPC combination.     

Integration in Victorian Schools: A Review of Policy and Progress (1984‐1989)

ALTHOUGH a dual system of special education has existed for many years in Victoria, the Report of the Ministerial Review of Educational Services for the Disabled(Collins, 1984) clearly revealed the Government's intentions to hasten the integration movement. The five guiding principles of the Review, which are firmly based on social justice and equity issues, shaped Ministerial policy and practices. These guidelines, associated Ministerial documents and memoranda, and resultant policies, structures and services are discussed in detail. The progress of integration in Victorian schools since the Review is outlined, barriers identified and strategies to overcome these obstructions or difficulties provided.     

Changes in locomotive rates during senior elite rugby league matches

Abstract

The aim of this study was to quantify the changes in locomotive rates across the duration of senior elite rugby league matches. A semi-automated image recognition system (ProZone 3, ProZone®, Leeds, England) was used to track the movements of 59 players from six teams during three competitive matches. The players were classified into one of four positional groups: props (n = 9), back row (n = 9), pivots (n = 14) or outside backs (n = 27). Players' movements were classified as low, high or very high intensity running and reported as locomotive rates (distance covered per minute played) for successive quarters of each match. Analysis of variance revealed that only the outside backs showed a significantly lower overall locomotive rate during the final quarter compared to the first (P < 0.05). However, locomotive rates for high and very high intensity running during the final quarter were significantly lower (P < 0.05) than the first quarter among outside backs, pivots and props despite no change in the rate of involvements in contact. On the basis of these findings, it is suggested that high and very high intensity running locomotive rates may be more affective methods of detecting fatigue during competitive matches than overall locomotive rate.     

Aerobic exercise and type a behaviour

The Type A behaviour pattern is a well‐documented, if controversial, risk factor for coronary heart disease. Surprisingly, relatively little work has been reported on ways of modifying this behaviour pattern. Aerobic exercise, with its demonstrated benefits for both cardiovascular reactivity and psychological ‘well‐being’, is a promising treatment. The literature is reviewed and recommendations are made for practical applications and future research.     

Concurrent and Separate Grade-Groups Linking Procedures for Vertical Scaling

Reading and Mathematics tests of multiple-choice items for grades Kindergarten through 9 were vertically scaled using the three-parameter logistic model and two different scaling procedures: concurrent and separate by grade groups. Item parameters were estimated using Markov chain Monte Carlo methodology while fixing the grade 4 population abilities to have a standard normal distribution. For the separate grade-groups scaling, grade groupings were linked using the Stocking and Lord test characteristic curve procedure. Abilities were estimated using the maximum-likelihood method. In either content area, scatterplots of item difficulty, discrimination, and ability estimates from the two methods showed consistently strong linear relationships. However, as grade deviated from the base grade of four, the best-fit linear line through the pairs of item discriminations started to rotate away from the identity line. This indicated the discrimination estimates from the separate grade-groups procedure for extreme grades to be, on average, higher than those from the concurrent analysis. The study also observed some systematic change in score variability across grades. In general, the two vertical scaling approaches yielded similar results at more grades in Reading than in Mathematics.     

A practice-based approach to student reflection in the workplace during a Work-Integrated Learning placement

In the Work-Integrated Learning (WIL) curriculum, reflection on workplace activities is widely used to support student learning. Recent critiques have demonstrated the limitations of current approaches to support students' reflective learning of workplace practices. By employing a practice-based approach, we seek to refocus WIL reflection on workplace practices, emphasising the ‘embedded (social), engaged (practice) and embodied (material) aspects' of students' reflective practices in the workplace. We argue that reflection-in-the-midst-of-action includes an often-overlooked phenomenological contribution that shifts attention from cognition to action. This study uses a case study of one typical WIL student to illustrate the importance of reflection-in-the-midst-of-action and the limitations of pedagogical structure using an e-log and reflective journal to capture reflection-in-the-midst-of-action. We argue that the move to consider reflection as a practice, and the move to refocus reflection to reflection-in-the-midst-of-action, supports a learning approach that is more congruent with workplace action and context.
