Ground reaction forces produced by two different hockey skating arm swing techniques

The arm swing in hockey skating can have a positive effect on the forces produced by each skate, and the resulting velocity from each push off. The main purpose of this study was to measure the differences in ground reaction forces (GRFs) produced from an anteroposterior versus a mediolateral style hockey skating arm swing. Twenty-four elite-level female hockey players performed each technique while standing on a ground-mounted force platform, and all trials were filmed using two video cameras. Force data was assessed for peak scaled GRFs in the frontal and sagittal planes, and resultant GRF magnitude and direction. Upper limb kinematics were assessed from the video using Dartfish video analysis software, confirming that the subjects successfully performed two distinct arm swing techniques. The mediolateral arm swing used a mean of 18.38° of glenohumeral flexion/extension and 183.68° of glenohumeral abduction/adduction while the anteroposterior technique used 214.17° and 28.97° respectively. The results of this study confirmed that the mediolateral arm swing produced 37% greater frontal plane and 33% less sagittal plane GRFs than the anteroposterior arm swing. The magnitudes of the resultant GRFs were not significantly different between the two techniques; however, the mediolateral technique produced a resultant GRF with a significantly larger angle from the direction of travel (44.44°) as compared to the anteroposterior technique (31.60°). The results of this study suggest that the direction of GRFs produced by the mediolateral arm swing more closely mimic the direction of lower limb propulsion during the skating stride.     

Book reviews

When designing lessons to meet the needs of our increasingly diverse population of students, educators need to rethink planning and structuring lessons so that all students achieve better results. Therefore, teacher preparation programmes need to prepare pre‐service teachers accordingly. Within this paper, a new lesson planning template is unveiled that builds on many of the foundational concepts of inclusive education. This template is meant for teacher educators to use with pre‐service teachers across the curriculum to guide the design of inclusive lessons. This paper discusses the foundations, unique features, and applications of this student‐centred lesson design template to create creative and active learning for students in inclusive classrooms.     

Ecological footprinting: its potential as a tool for change in preservice teacher education

Environmental and sustainability issues pose challenges for society. Although education is seen as being a contributor to addressing sustainability, teacher education has been slow to act in preparing future teachers to teach sustainability. Recent Australian curriculum documents nominate sustainability as one of three cross-curriculum priorities. In one Australian university course, an Ecological Footprint Calculator tool has been employed to challenge preservice early childhood teachers to consider the sustainability of their lifestyles as a means for engaging them in learning and teaching for sustainability. Students enrolled in an integrated arts and humanities subject voluntarily engaged with the online calculator and shared their findings on an electronic discussion forum. These postings then became the basis of qualitative analysis and discussion. Data categories included reactions and reflections on reasons for the ‘heaviness’ of their footprints, student reactions leading to actions to reduce their footprints, reflections on the implications of the footprint results for future teaching, reactions that considered the need for societal change, and reflections on the integration of sustainability with the visual arts. The power of the tool’s application to stimulate interest in sustainability and education for sustainability more broadly in teacher education is explored.     

Turning collegial governance on its head: symbolic violence,hegemony and the academic board

This article draws on Bourdieu’s theorisation of domination and Gramsci’s notions of hegemony within the context of a larger empirical study of Australian university academic governance, and of academic boards (also known as academic senates or faculty senates) in particular. Reporting data that suggest a continued but radically altered form of collegial governance in which hegemony is exercised by management rather than by the professor, it theorises the domination of academic boards within western democratic universities. However, traditional collegial governance is also dependent upon a community of scholars, a role historically played by the academic board. In view of the suggested transition in collegial governance and the resultant convergence of academic work and management, the article concludes with questions about whether academic boards can continue to serve as communities of scholars in future.     

Gauging Item Alignment Through Online Systems While Controlling for Rater Effects

The alignment of test items to content standards is critical to the validity of decisions made from standards‐based tests. Generally, alignment is determined based on judgments made by a panel of content experts with either ratings averaged or via a consensus reached through discussion. When the pool of items to be reviewed is large, or the content‐matter experts are broadly distributed geographically, panel methods present significant challenges. This article illustrates the use of an online methodology for gauging item alignment that does not require that raters convene in person, reduces the overall cost of the study, increases time flexibility, and offers an efficient means for reviewing large item banks. Latent trait methods are applied to the data to control for between‐rater severity, evaluate intrarater consistency, and provide item‐level diagnostic statistics. Use of this methodology is illustrated with a large pool (1,345) of interim‐formative mathematics test items. Implications for the field and limitations of this approach are discussed.     

Use of context in the word recognition process by adults with a significant history of reading difficulties

We examined whether university students who report a significant history of reading difficulties (RD; n = 24) differed from university students with no history of reading difficulties (NRD; n = 31) in how sentence context affects word recognition. Experiment 1 found no differences in how congruent sentence primes or syntactic manipulations of the sentence primes affected the performance of the two groups. However, only the RD group displayed a significant inhibition effect when the target word was preceded by an incongruent sentence prime. Experiment 2 found that the groups differed in how meaning frequency of the target word and context strength of the sentence prime affected word recognition latencies. The results suggest that the RD participants’ performance is context-sensitive and better explained by interactive models of language processing than by modular models.     

Bridging campus and field settings through professional development schools

Abstract

An assessment of the hopes, ambitions, and quality of life for millions of our young people leaves us with one inescapable fact—America is losing sight of many of its children and youth. There is grim and persistent evidence that our concern for the emotional and psychological well‐being of young people continues to wane—a fact that could have grave consequences for the future of our nation. This article advances a cause to which the next generation of professional teacher educators might productively dedicate themselves—a call for a renewal of spirit and a commitment to nourishing the conscience of our profession.     

Effectiveness of a Conflict Resolution Training Program in Changing Graduate Students Style of Managing Conflict with their Faculty Advisors

We investigated the conflict management preferences of graduate students with their faculty advisors and assessed the effects of participating in a conflict resolution workshop on those preferences. One hundred and twenty-one graduate students completed the pre-workshop surveys, and 69 participants completed the post-workshop surveys after seven workshops conducted over a 3 year period. Nineteen subjects participated in three post-workshop focus groups. The quantitative pre-workshop data showed that avoidance and accommodation styles for managing conflict were preferred among participants. Participants showed a trend towards a statistically significant increase in the collaborating score post-workshop relative to pre-workshop levels. The qualitative data indicated that students applied skills taught during the workshop, including interest-based principles, when interacting with faculty.
