The effects of testing procedure on critical fall height determination for third-generation synthetic turf

Test procedures and their accuracy in determining critical fall height (CFH) on sporting grounds are paramount to player safety. The procedure currently adopted for synthetic turf in Australian football [1] consists of four consecutive drops at various drop heights at three test locations on the sample. The quantity and packing of the infill in third-generation turf and the pooling effect of the rubber particles with consecutive drops suggests that the current standard protocol may need re-assessment. Therefore, the purpose of this pilot study was to investigate whether current methods of testing for CFH are appropriate for third-generation synthetic turf or whether an alternative or adapted method needs to be developed. CFH was measured, using a HISUN Uniaxe-II Impact Tester, on 12 combinations of synthetic turf samples (four different products with three shock pad options). Three conditions were investigated on each sample; the existing protocol; an alternative 12 single-drop protocol and four single drops from the CFH determined from the existing protocol. A significant difference was found for both absolute and percentage difference between the existing and 12 single-drop protocol, with p = 0.001 and t = 4.33 and p < 0.001 and t = 6.03, respectively. There was also a significant difference between the CFH reached with and without a shock pad for both the existing protocol and the 12 single-drop protocol. The results of this pilot study demonstrate that differences do occur with alterations to the existing protocol and highlight the need for a more detailed characterisation of testing methods on third-generation synthetic turf and the response of surfaces to them.

Using web design with pre‐service teachers as a means of creating a collaborative learning environment

This study involves a group of over 300 third‐year Bachelor of Education students attending St Patrick’s College of Education, Dublin, Ireland. Working in groups of not more than three, the students completed an assignment to create a WebQuest. On construction of the WebQuest the students were asked to reflect on the experience, considering issues such as collaboration, cooperation, planning, decision‐making, time management, project direction and design. They were also asked to reflect on the impact of the exercise on their own learning styles and its influence on their concepts of teaching and learning. Finally, they were asked if the exercise had affected their ideas of how to use the Internet in school and if they envisage using WebQuests as part of their teaching in the future. Their reflections were facilitated by a questionnaire. Results of the project have implications for future course design.

Die Erstellung eines Webdesigns durch Lehramtsstudenten als Mittel, eine kollaborative Lernumgebung zu erzeugen

Diese Studie umfasst eine Gruppe von mehr als 300 Lehrerstudenten des St. Patrick’s College of Education in Dublin, Irland. In Gruppen von nicht mehr als drei Personen füllten die Studenten einen Zusatz zur Erzeugung eines Webfragebogens aus. Im Verlauf der Arbeit an der Konstruktion des WebQuest wurden sie aufgefordert, über die Erfahrung mit Dingen wie Zusammenarbeit, Kooperation, Planung, Entscheidungsfindung, Zeitmanagement, Projektziel und Konzeption nachzudenken. Zusätzlich wurden sie angehalten, über den Einfluss dieser Übung auf ihren eigenen Lehrstil und auf ihre Konzepte von Lehren und Lernen zu reflektieren. Schließlich wurden sie befragt, ob diese Übung ihre Einschätzung, wie das Internet im Schulunterricht genutzt werden könne und ob sie sich vorstellen könnten, WebQuests im Rahmen ihres zukünftigen Unterrichts einzusetzen. Ihre Reflexionen wurden durch einen Fragebogen unterstützt. Die Ergebnisse des Projekts haben Auswirkungen auf zukünftige Lehrgangsentwürfe.

Comment utiliser la conception de sites Web avec des enseignants en formation initiale pour créer un environnement d’apprentissage collaboratif

Cette étude porte sur un groupe de plus de 300 étudiants de Licence en Education inscrits à l’Institut St Patrick de formation des Maîtres de Dublin. Travaillant en groupes de trois au maximum, ces étudiants ont mené à bien un projet de création d’un WebQuest.Au moment de la construction de ce WebQuest, on a demandé aux étudiants de réfléchir sur l’expérience en cours et sur les problèmes de collaboration, de coopération, de planification, de prise de décision,de gestion du temps,d’ orientation et de conception du projet. On leur a aussi demandé de réfléchir à l’impact de cet exercice sur leurs propres styles d’apprentissage et à son influence sur la façon dont ils envisageaient l’enseignement et l’apprentissage.On les a finalement interrogés pour savoir si cet exercice avait affecté leur façon de penser aux usages de l’Internet à l’école et si ils (elles) envisageaient d’utiliser WebQuest dans leur enseignement à l’avenir. Un questionnaire a facilité la réponse à ces questions. Les résultats de ce projet auront des conséquences pour la conception des cours à venir.     

Disappearing acts: resuscitative reflections on the academy

To resuscitate means to revive or make go on. This paper is an exploration of my first six months at a Canadian university as a doctoral student. Through a chronological narrative, I explore my experiences through the governing relations of the academy as a way to provoke dialogue about the role of feminist researcher in the institution. By comparing feminine subjectivity of the ‘woman returner’ (Hughes, 2002 Hughes, C. 2002. Beyond the poststructuralist‐modern impasse: the woman returner as ‘exile’ and ‘nomad’. Gender and Education, 14: 411–424. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) through the character in a feminist science fiction novel the challenges of the academy find resonance and meaning in a reinvention of self.     

The effect of stud configuration on rotational traction using the studded boot apparatus

Due to its associated injury risk, rotational traction is a frequently measured natural turf surface property. The most commonly used equipment, the studded boot apparatus (SBA), consists of a circular stud configuration that does not replicate the stud pattern on a regular football boot and may under or over estimate the surface traction. The aim of this study was to establish potential differences in the rotational traction measured between the current stud configuration on the SBA and the stud configuration on the most commonly used Australian football boots. The original studded boot had significantly higher rotational traction than the moulded stud sole or bladed sole. Location, quality and time tested all interacted significantly with the rotational traction measured. The current SBA may not accurately represent the rotational traction experienced by football players, and consequently may not be the most appropriate configuration to assess the relationship between rotational traction and injuries.     

Teacher-centered professionalism: a feminist perspective on supported access to digital knowledge

This qualitative study creates a case for teacher learning through increased access to digital knowledge and information made available through the Internet. I ask how reading environments, supported through online access to scholarly texts, might create intellectual engagement and transformative possibilities for teachers within their professional learning communities. This study is based on the experiences of six female teachers’ participation in a research project in a large urban center in Western Canada. Through individual and group interview data, I present three examples of how the teachers engaged in a discourse of social justice. This paper demonstrates the value of providing teachers with digital access to public knowledge through the Internet as a new and distinctive approach to teacher learning that can deepen understanding of the profession within a collective association of learning.     

Gaining access to support for children with special educational needs in the early years in Ireland: parental perspectives

Ireland has a policy of inclusive education to enable children with special educational needs to access education alongside their peers. The introduction of early assessment procedures to ensure that children receive support and resources on entering formal education has been an important strategy for delivery of this policy. This paper uses data from interviews with parents and from focus groups with professionals involved in assessment to discuss the efficacy of this procedure. The findings suggest that whilst a policy has been adopted, much remains to be done to ensure that provision of assessment and adequate resources is achieved.     

Predicting Engineering Student Attrition Risk Using a Probabilistic Neural Network and Comparing Results with a Backpropagation Neural Network and Logistic Regression

As the need for engineers continues to increase, a growing focus has been placed on recruiting students into the field of engineering and retaining the students who select engineering as their field of study. As a result of this concentration on student retention, numerous studies have been conducted to identify, understand, and confirm relationships between student attributes and attrition. Methods of prediction have also been evaluated and compared. Utilizing the attributes found in previous studies to have correlation with student attrition, this study considers the results of three different prediction methods—logistic regression, a multi-layer perceptron artificial neural network, and a probabilistic neural network (PNN)—to predict engineering student retention at a case study university. The purpose of this study was to introduce the PNN to the study of engineering student retention prediction and compare the results of the PNN to other commonly used methods in this field of study. The accuracy, sensitivity, specificity and overall results for each method are reported, compared, and discussed as the major contribution of this paper.
