The relationship between bowling action classification and three-dimensional lower trunk motion in fast bowlers in cricket

Lower back injuries, specifically lumbar stress fractures, account for the most lost playing time in professional cricket. The aims of this study were to quantify the proportion of lower trunk motion used during the delivery stride of fast bowling and to examine the relationship between the current fast bowling action classification system and potentially injurious kinematics of the lower trunk. Three-dimensional kinematic data were collected from 50 male professional fast bowlers during a standing active range of motion trial and three fast bowling trials. A high percentage of the fast bowlers used a mixed bowling action attributable to having shoulder counter-rotation greater than 30 degrees. The greatest proportion of lower trunk extension (26%), contralateral side-flexion (129%), and ipsilateral rotation (79%) was used during the front foot contact phase of the fast bowling delivery stride. There was no significant difference in the proportions of available lower trunk extension, contralateral side-flexion, and ipsilateral rotation range of motion used during fast bowling by mixed and non-mixed action bowlers. Motion of the lower trunk, particularly side-flexion, during front foot contact, in addition to variables previously known to be related to back injury (e.g. shoulder counter-rotation), should be examined in future cross-sectional and prospective studies examining the fast bowling action and low back injury.     

Student Views of Concept Mapping Use in Introductory Tertiary Biology Classes

Introductory tertiary level science classes (i.e., at the university or post-compulsory school level) including those for biology face increasing diversity in intake. Previous research has indicated university level teachers assume a certain level of prior knowledge which may or may not be possessed by such students. This report focuses on the use of concept mapping in introductory biology tutorial classes. The research findings suggest that the students found the use of concept mapping enjoyable and that it can enhance meaningful learning for topics that require students to link concepts.     

Comparative education research: poststructuralist possibilities [1]

Various authors have charted the changing and intertwined emphases in comparative education over the last four decades, including modernisation and development, socially critical and neo-Marxist perspectives, and ethnography and phenomenology. Ideas from postpositivist thinking—postmodernism, poststructuralism, and postcolonialism—have been particularly challenging to comparative education, because they disrupt the power structures that imbue much of comparative education and challenge the metanarratives of progress, modernity, dominance and subordination that have been the life blood of the major sets of ideas in the field. In order to examine in part the way in which comparative education is opening itself up to these challenging paradigms, we examine the shifts, developments and omissions in the use of poststructural theoretical frameworks and methodologies in comparative education in the period 1991–1999 and provide a constructive contribution to the debates about the future directions of comparative education in a rapidly internationalising and globalising world.     

Seeking the Passionate Career: First‐in‐Family Enabling Students and the Idea of the Australian University

This paper examines the idea of the university from the first‐in‐family enabling students’ perspective. It provides an overview of the current crisis of meaning in scholarly commentary that points to a spectrum of meanings about the university. This spectrum ranges from the ancient imaginary of the monastic university as ‘ivory tower’ to the instrumental idea of the entrepreneurial university. The analysis then reports on the idea of the university in over 40 interviews and surveys of first‐in‐family enabling students who attended two large regional Australian universities in 2014. Their metaphorical understandings of the university constitute a powerful imaginary about what a university is and can do for individuals and the wider society. For many, the resolution of the individualistic passion for knowledge of ‘ivory tower’ studies and the commitment to the social and economic usefulness of the fully engaged entrepreneurial university can be found in the pursuit of the passionate career.     

Four spheres of knowledge required: an international study of the professional development of literacy/English teacher educators

This paper reports on a research study of 28 literacy teacher educators (LTE) in four countries: Canada, the USA, England and Australia. It identifies three main forms of professional development: informal, formal and communities of practice and four spheres of knowledge: research; pedagogy of higher education; literacy and literacy teaching; and current school district and government initiatives. The study reveals the sheer scale of knowledge required to be an effective LTE and demonstrates how participants used the three forms of professional development to enhance their knowledge in each sphere. It concludes that the professional development of teacher educators is not conducted systematically; rather, it is quite ad hoc with much of it occurring through learning while doing. All had to construct their own programmes for professional development, which added yet another layer to their responsibilities.     

Hunting and gathering: new imperatives in mapping and collecting student learning data to assure quality outcomes

Assurance of learning (AOL) is a quality enhancement and quality assurance process used in higher education. It involves a process of determining programme learning outcomes and standards, and systematically gathering evidence to measure students' performance on these. The systematic assessment of whole-of-programme outcomes provides a basis for curriculum development and management, continuous improvement, and accreditation. To better understand how AOL processes operate, a national study of university practices across one discipline area, business and management, was undertaken. To solicit data on AOL practice, interviews were undertaken with a sample of business school representatives (n?=?25). Two key processes emerged: (1) mapping of graduate attributes and (2) collection of assurance data. External drivers such as professional accreditation and government legislation were the primary reasons for undertaking AOL outcomes but intrinsic motivators in relation to continuous improvement were also evident. The facilitation of academic commitment was achieved through an embedded approach to AOL by the majority of universities in the study. A sustainable and inclusive process of AOL was seen to support wider stakeholder engagement in the development of higher education learning outcomes.     

Inspiring Instructional Change in Elementary School Science: The Relationship Between Enhanced Self-efficacy and Teacher Practices

This longitudinal study examined the extent to which teachers’ participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second grade classrooms in rural school districts. Data sources, administered pre-program and at the end of each year, included a self-efficacy assessment and teacher survey. Interviews and classroom observations provided corroborating data about teachers’ beliefs and science instruction. Results showed significant increases in teachers’ overall self-efficacy in teaching science, personal efficacy, and outcome expectancy efficacy during the 3 years. Gains in self-efficacy were correlated with changes in reported instructional practices, particularly student participation activities. However, changes in self-efficacy tended not to be correlated with changes in instructional time. Contextual factors beyond teachers’ direct control, such as curricular and testing requirements in mathematics and language arts influenced time allotted to science instruction.     

A Descriptive Survey of the Educational Preparation and Practices of Antenatal Educators in Ireland

Antenatal education is recommended to prospective parents, yet little is known about the educational preparation of the facilitators of this education, or of the educational practices they use. The aim of this study was to investigate the educational preparation and practices of antenatal educators in Ireland. Data were collected using a questionnaire structured on the three components (abilities, opportunities, and means) of Stamler’s theoretical framework of enablement. Eighty-four of the 120 antenatal educators responded (70%), and this included midwives, public health nurses, physiotherapists, and private antenatal educators. Findings describe a picture of varied educational preparation for the antenatal educator with a range of educational practices being used. Within public antenatal classes, large class size was a barrier to providing a participatory educational approach.
