Using Decision Tree Analysis to Understand Foundation Science Student Performance. Insight Gained at One South African University     

Nicola Frances Kirby  Edith Roslyn Dempster 《International Journal of Science Education》2013,35(17):2825-2847

The Foundation Programme of the Centre for Science Access at the University of KwaZulu-Natal, South Africa provides access to tertiary science studies to educationally disadvantaged students who do not meet formal faculty entrance requirements. The low number of students proceeding from the programme into mainstream is of concern, particularly given the national imperative to increase participation and levels of performance in tertiary-level science. An attempt was made to understand foundation student performance in a campus of this university, with the view to identifying challenges and opportunities for remediation in the curriculum and processes of selection into the programme. A classification and regression tree analysis was used to identify which variables best described student performance. The explanatory variables included biographical and school-history data, performance in selection tests, and socio-economic data pertaining to their year in the programme. The results illustrate the prognostic reliability of the model used to select students, raise concerns about the inefficiency of school performance indicators as a measure of students' academic potential in the Foundation Programme, and highlight the importance of accommodation arrangements and financial support for student success in their access year.  相似文献

Combined individual scrummaging kinetics and muscular power predict competitive team scrum success     

Andrew Green  Chloe Dafkin  Samantha Kerr  Warrick McKinon 《European Journal of Sport Science》2017,17(8):994-1003

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.  相似文献   

A comparison between mainstream and action sport industries in Australia: A case study of the skateboarding cluster     

Pamm Kellett  Roslyn Russell 《Sport Management Review》2009,12(2):66-78

The action sport industry is a high growth sector that attracts the lucrative Generation Y market. Although there is a growing body of literature that examines the characteristics and traits of the Generation Y market as consumers of action sports, little is known about the supply side of the action sports industry. This paper illustrates through the example of the skateboarding sport cluster, that this sector has evolved in an organic, almost chaotic manner very different to that of the mainstream sports industry. Entrepreneurs have taken advantage of the open system, the lack of formal boundaries and the risk loving nature of the market to grow the sector into a very profitable industry. The paper specifically illustrates the differences to mainstream sports in relation to provision of facilities, program development and pathways and the roles of suppliers, councils and program developers.  相似文献   

Kinematics of the field hockey penalty corner push-in     

Kerr R  Ness K 《Sports biomechanics / International Society of Biomechanics in Sports》2006,5(1):47-61

The aims of the study were to determine those variables that significantly affect push-in execution and thereby formulate coaching recommendations specific to the push-in. Two 50 Hz video cameras recorded transverse and longitudinal views of push-in trials performed by eight experienced and nine inexperienced male push-in performers. Video footage was digitized for data analysis of ball speed, stance width, drag distance, drag time, drag speed, centre of massy displacement and segment and stick displacements and velocities. Experienced push-in performers demonstrated a significantly greater (p < 0.05) stance width, a significantly greater distance between the ball and the front foot at the start of the push-in and a significantly faster ball speed than inexperienced performers. In addition, the experienced performers showed a significant positive correlation between ball speed and playing experience and tended to adopt a combination of simultaneous and sequential segment rotation to achieve accuracy and fast ball speed. The study yielded the following coaching recommendations for enhanced push-in performance: maximize drag distance by maximizing front foot-ball distance at the start of the push-in; use a combination of simultaneous and sequential segment rotations to optimise both accuracy and ball speed and maximize drag speed.  相似文献

Development of an Educational Innovation Incubator     

Odin Jurkowski  Shantia Kerr 《TechTrends》2010,54(2):72-77

The Educational Innovation Incubator is an electronic classroom designed to evolve at the University of Central Missouri. This newly enacted endeavor is a place for faculty and students to combine the scholarship of teaching and learning into their courses by experimenting with the latest technologies in education. This paper describes the process that was used for this development and what current form has taken shape.  相似文献   

Changing the Political Culture: The Advisory Group on Education for Citizenship and the Teaching of Democracy in Schools     

David Kerr 《牛津教育评论》2013,39(1-2):275-284

This article discusses the background to and deliberations of the Advisory Group on Education for Citizenship and the Teaching Democracy in Schools established by Secretary of State for Education and Employment David Blunkett. The final report of the Advisory Group was published in September 1998. The article discusses the Group's main recommendations. As regards implementation, the article identifies four challenges: curriculum reform, the relationship between schools and communities, the difficulties of citizen life in a globalised context, and the issue of individuals' participation in politics and society.  相似文献   

Habituation: A Method for Cultivating Starting Points in the Ethical Life     

Jeannie Kerr 《Journal of Philosophy of Education》2011,45(4):643-655

The Aristotelian concept of habituation is receiving mounting and warranted interest in educational circles, but has also been subject to different lines of interpretation and critique. In this article, I bring forward Aristotle's words on habituation, and then clarify the two lines of interpretation that have developed in the contemporary philosophical literature. I argue that the mechanical interpretation contains an intellectualist bias and then argue a cognitivist view that positions habituation as the only method appropriate to cultivating the starting points of the ethical life. I contend, contrary to the popular view, that the starting points are non‐discursive and not subject to explanation, and thus require the non‐discursive method of habituation. I conclude with some thoughts for moral education that answer critiques of habituation concerning the role of reasoning and critical independence of students.  相似文献
