The Impact of an Ongoing Professional Development Program on Prekindergarten Teachers' Mathematics Practices     

Jenifer S. Thornton  Courtney L. Crim  Jacqueline Hawkins 《Journal of Early Childhood Teacher Education》2013,34(2):150-161

Mathematics is a natural part of daily life for young children as they explore and investigate the world around them. To build on these experiences, and to begin establishing a mathematical foundation, early childhood educators must not only be knowledgeable about mathematical concepts, they must also be aware of the most developmentally appropriate ways in which to teach these concepts to young children. After participation in an ongoing professional development program, specifically targeting teachers of prekindergarten children in public school, Preschool Programs for Children with Disabilities (PPCD), Head Start, and child care settings, teachers reported positive changes in math practices. Specifically, teachers reported a stronger alignment to national mathematics standards and increased awareness pertaining to developmentally appropriate mathematics practices as they apply to early childhood classrooms. Teachers reported a shift towards more hands-on activities and a shift away from the use of worksheets in their prekindergarten classrooms. Implications from this study suggest that ongoing professional development that is designed to meet the specific needs of early childhood educators can have a positive impact on reported mathematics content knowledge and instructional practices.  相似文献   

Evaluating the self and the other: Imagined intercultural contact within a ‘native-speaker’ dependent foreign language context     

Damian J. Rivers 《Int J Intercult Relat》2011,35(6):842-852

Recent research has shown that imagined intercultural contact, being based upon the adoption of principles of mental imagery and imagination, is able to elicit similar emotional, attitudinal and motivational responses as actual lived contact experiences. Furthermore, it has been noted that possessing the multiple competencies required to successfully negotiate an intercultural contact encounter with a target language speaker represents one of the most prominent sources of motivation for many foreign language learners. Therefore, situated within the context of a Japanese foreign language university which exhibits a dependency on ‘native-speaker’ English teachers from inner-circle (Kachru, 1985) countries, this paper showcases a social psychological study undertaken with 120 Japanese English language learners which sought to explore various dimensions of imagined intercultural contact via evaluations of the self and three intercultural others of different racial and ethnic appearance across two specific contact situations (positive and neutral). The outcomes are discussed in relation to underlying theories, as well as to the practical implications created for the improvement of foreign language teaching and learning practices which specifically seek to incorporate an explicit intercultural dimension.  相似文献   

Theory and practice in sport psychology and motor behaviour needs to be constrained by integrative modelling of brain and behaviour     

Damian Keil  Paul Holmes  Simon Bennett  Keith Davids  Nick Smith 《Journal of sports sciences》2013,31(6):433-443

Because of advances in technology, the non-invasive study of the human brain has enhanced the knowledge base within the neurosciences, resulting in an increased impact on the psychological study of human behaviour. We argue that application of this knowledge base should be considered in theoretical modelling within sport psychology and motor behaviour alongside existing ideas. We propose that interventions founded on current theoretical and empirical understanding in both psychology and the neurosciences may ultimately lead to greater benefits for athletes during practice and performance. As vehicles for exploring the arguments of a greater integration of psychology and neurosciences research, imagery and perception–action within the sport psychology and motor behaviour domains will serve as exemplars. Current neuroscience evidence will be discussed in relation to theoretical developments; the implications for sport scientists will be considered.  相似文献   

Cardiorespiratory,hormonal and haematological responses to submaximal cycling performed 2 days after eccentric or concentric exercise bouts     

Damian Farrow  Bruce Abernethy 《Journal of sports sciences》2013,31(6):471-485

The aim of this experiment was to determine the effectiveness of two video-based perceptual training approaches designed to improve the anticipatory skills of junior tennis players. Players were assigned equally to an explicit learning group, an implicit learning group, a placebo group or a control group. A progressive temporal occlusion paradigm was used to examine, before and after training, the ability of the players to predict the direction of an opponent's service in an in-vivo on-court setting. The players responded either through hitting a return stroke or making a verbal prediction of stroke direction. Results revealed that the implicit learning group, whose training required them to predict serve speed direction while viewing temporally occluded video footage of the return-of-serve scenario, significantly improved their prediction accuracy after the training intervention. However, this training effect dissipated after a 32 day unfilled retention interval. The explicit learning group, who received instructions about the specific aspects of the pre-contact service kinematics that are informative with respect to service direction, did not demonstrate any significant performance improvements after the intervention. This, together with the absence of any significant improvements for the placebo and control groups, demonstrated that the improvement observed for the implicit learning group was not a consequence of either expectancy or familiarity effects.  相似文献   

Lactate accumulation following isometric exercise training and its relationship with reduced resting blood pressure     

Gavin R. Devereux  Damian Coleman  Jonathan D. Wiles  Ian Swaine 《Journal of sports sciences》2013,31(11):1141-1148

Abstract

The purpose of this study was (a) to assess lactate accumulation during isometric exercise, and to quantify the shifts in accumulation following isometric training; and (b) to relate any training-induced changes in lactate accumulation to reductions in resting blood pressure. Eleven male participants undertook isometric training for a 4-week period using bilateral-leg exercise. Training caused reductions in systolic, diastolic, and mean arterial resting blood pressure (of ?4.9 ± 6.3 mmHg, P = 0.01; ?2.6 ± 3.0 mmHg, P = 0.01; and ?2.6 ± 2.3 mmHg, P = 0.001 respectively; mean ± s). These were accompanied by changes in muscle activity, taken as electromyographic activity to reach a given lactate concentration (from 114 ± 22 to 131 ± 27 mV and from 136 ± 25 to 155 ± 34 mV for 3 and 4 mmol · L^?1 respectively. Training intensity expressed relative to peak lactate was correlated with reduced resting systolic and mean arterial blood pressure. Training caused significant shifts in lactate accumulation, and reductions in resting blood pressure are strongly related to training intensity, when expressed relative to pre-training peak lactate. This suggests that higher levels of local muscle anaerobiosis may promote the training-induced reductions in resting blood pressure.  相似文献   

Examining the influence of acute instructional approaches on the decision-making performance of experienced team field sport players     

Tim Buszard  Damian Farrow 《Journal of sports sciences》2013,31(3):238-247

Abstract

We examined the influence of instructions on decision-making accuracy using video simulations of game-specific scenarios in Australian football. Skilled performers (average age of 23.4 ± 4.2 years) differing in experience (range 0 to 339 Australian Football League (AFL) matches) assumed the role of the key attacker and verbally indicated their kicking decision. Participants were randomly stratified into three groups: (1) LOOSE (n = 15) – instructed to “keep the ball away from the loose defender”; (2) TTF (n = 15) – instructed to “take the first option”; and (3) NI (control) (n = 16) – given no instructions. Gaze behaviour for a subset of participants (n = 20) was recorded. In the scenarios with an even number of attacking and defensive players, the decision-making accuracy of LOOSE was greater than TTF. This difference was most evident for lesser experienced performers, highlighting that lesser experienced performers are more affected by instructional foci than experienced performers. Gaze behaviour was not affected by instructional foci, but visual search rate was greater in scenarios of greater player number and complexity.  相似文献   

Enhancing skill transfer in tennis using representative learning design     

Lyndon Krause  Damian Farrow  Ross Pinder  Tim Buszard  Stephanie Kovalchik  Machar Reid 《Journal of sports sciences》2013,31(22):2560-2568

ABSTRACT

Representative Learning Design advocates that practice should simulate the demands of competition. The effectiveness of increased task representativeness to improve serving skill of junior tennis players was assessed after a six-week intervention. Thirty-three participants (15.4 ± 1.9 years of age) were assigned to one of the three groups; “serve only” (participants served to no opponent), “serve return” (participants served to an opponent and hit no extra shots) or “serve +3^rd” (participants served to an opponent and hit one extra shot). Using the validated representative practice assessment tool (RPAT) tasks were considered to be low, moderate and high in task representativeness, respectively. Participants hit 56 serves, twice weekly for 6-weeks. Pre and post serving performances were assessed via a skill test and in-situ matchplay using SportsCode and HawkEye ball tracking, respectively. Serve speed, landing locations, serve angle and positional advantage was obtained for 1^st and 2^nd serves. The relationship between increasing representativeness and increased skill acquisition was not linear, rather different behaviours emerged. For example, when hitting 2^nd serves in matchplay, the low and moderate representative groups prioritised speed over placement while the high representative group prioritised placement over speed. Coaches therefore need to carefully individualise representativeness to an athletes’ specific needs.  相似文献   

Creating Appropriate Training Environments to Improve Technical,Decision-Making,and Physical Skills in Field Hockey     

Ewout A. Timmerman  Geert J. P. Savelsbergh  Damian Farrow 《Research quarterly for exercise and sport》2019,90(2):180-189

Purpose: The purpose of this study was to determine the influence of eight different small-sided games (SSG) on physical, technical, and decision-making demands of training environments in U14 field hockey. Methods: A total of 13 participants played eight different training games consisting of two 7.5-minute halves, where number of players (three per side or six per side) and/or field characteristics (normal game, cage hockey game, possession game, and two-goals game) was manipulated. Match performance was determined by using notational analysis, and physical demands were determined by using GPS analyses. Results: Findings revealed that lowering the number of players increased the number of technical actions performed per player and the physical demands of the SSG. Findings of the field characteristics manipulation revealed that the possession game forced players to control the ball more as a team, which resulted in more passes (+4.82 passes) and fewer dribbles (?1.48 dribbles) and tackles (?0.69 tackles) compared to the normal game. The two-goals game led to players scoring more goals (+0.61 goals) compared to the normal game, while the cage hockey game increased passing (+1.46 passes) and physical demands (+7.32 meters per minute) compared to the normal game. Conclusion: It can be concluded from these findings that coaches and trainers are able to promote a change in playing behavior, and in turn the development of skills, by manipulating specific constraints of the training environment.  相似文献   

Pathways to Promotion: Redesigning a Community College Faculty Promotion Process     

Julie Shattuck  Tony Hawkins  Gregory Coldren  Kelly Trigger  Barbara Angleberger  Nancy Dankanich 《Community College Journal of Research & Practice》2018,42(1):4-19

This article reports on a design-based research project that is situated in a medium-size community college in Maryland. The project focused on exploring why the majority of full-time faculty was ranked as Assistant Professor or below, which did not reflect ranking at similar institutions. Under the leadership of the Provost, a task force analyzed the problem before designing a solution. The analysis phase of the project involved data collection and analysis through a faculty survey, a literature review, and a scan of other community colleges’ promotion practices. The design phase used the findings from the analysis stage to redesign the promotion system and construct evaluation and promotion tools. The article gives insight into how the interests of diverse stakeholders can be taken into account when creating accessible, alternative pathways to promotion for faculty while also supporting the institution’s mission and goals. For other community colleges looking at faculty promotion and evaluation, the results of this project highlight the importance of surveying faculty’s experiences with the existing system; learning from best practices at other institutions; including the participation of the faculty and administrators in the redesign process; and allowing for ample time to thoroughly explore the situation from many angles before coming to consensus. Although limited to a particular context, this study may be of interest to both community college faculty and leadership.  相似文献
