Performance tolerance and boat set-up in elite sprint kayaking

The aim of this study was to examine the inter-relationship between athlete morphology, equipment set-up and performance in elite sprint kayaking. Correlations applied to data from the 2000 Olympics were used to select the most important links between morphology and boat set-up--paddle grip width and foot-bar distance. Associations between body size and the above selected equipment set-ups were calculated using a Pearson correlation matrix, to facilitate the logical selection of independent variables as input for regression analyses. Significant (p < 0.01) regression equations were developed for the prediction of foot-bar distance (r2 = 0.589: standard error of estimate (SEE) = 4.48) and paddle grip width (r2 = 0.541: SEE = 3.08). Three national-standard sprint kayakers used their preferred set-up together with modifications of their predicted set-up, derived from Olympic data, to test performance tolerance in sprint kayaking. Mean coefficients of multiple determination over three trials for the three paddlers of 0.91, 0.91 and 0.92 for left paddle force, right paddle force, and paddle angle at water entry, respectively, were recorded when using their preferred set-up. These data showed that the paddlers produce consistent patterns of motion. The intervention of altering the boat set-up resulted in varying changes to boat speed. The mean preferred speed for the three paddlers of 4.47 m/s was reduced by 0.07 and 0.10 m/s when the above boat set-up was modified to a predicted and 'predicted plus one standard deviation'respectively. These changes in boat speed were the result of alterations in the mechanics of paddling technique.     

New Directions in Social Skills Assessment and Intervention for Elementary and Middle School Students

Social skills are important to the successful social and academic functioning of all students and play a significant role in avoiding or preventing negative responses from others. Social skills also are important aspects of effective schools. In this article, we emphasize the assessment and intervention of the academic side of social skills. That is, we examine the role that social skills play in facilitating individuals' learning and creation of a school environment where others can feel supported and motivated to learn. As a basis for this examination, we first review several key studies documenting interrelations among social skills and academic competence. Next, we briefly review current assessment practices focusing on rating scale methods for documenting students' social skills and perceptions of social support. Finally, we introduce an instructional approach called the Responsive Classroom (Charney, 1992) that has been shown to advance the development of elementary and middle school students' social skills and academic achievement, and result in supportive school environments for learners and teachers. We conclude with recommendations for researchers and practitioners to continue to consider the strong interrelations among social skills, academic functioning, and social support when working with all students in elementary and middle schools.     

Empowering teachers to implement innovative content in physical education through continuous professional development

The purpose of this study was to examine teacher perceptions regarding their experiences in a research-informed continuous professional development (CPD) initiative and its influence on their professional readiness to implement innovative content in physical education (PE). Participants included four PE teachers who engaged in a series of hands-on workshops and collaborative activities related to the design and implementation of a mountain biking unit in two middle schools. Qualitative data were collected through post-workshop surveys, semi-structured interviews, and a focus group. Data were analyzed using inductive content analysis, and results revealed four themes: (a) igniting change, (b) transferring to the classroom, (c) student response, and (d) sustaining beyond a single unit. Findings from this study reinforce the need for research-informed CPD efforts in PE and highlight its role in generating a sense of teacher empowerment and promoting systemic change within school-based PE.     

Active classroom participation in a Group Scribbles primary science classroom

A key stimulus of learning efficacy for students in the classroom is active participation and engagement in the learning process. This study examines the nature of teacher–student and student–student discourse when leveraged by an interactive technology—Group Scribbles (GS) in a Primary 5 Science classroom in Singapore which supports rapid collaborative knowledge building (RCKB). We envisaged nine design principles for RCKB in the design of lessons and postulated a logic model that links and explains the effects of our design principles to the ultimate goal of learning efficacy. We presented a case study of a GS lesson which shows that GS affordances leveraged by good lesson and activity design could enable the students to have more epistemic agency. Students had opportunities to participate spontaneously in class discussions by fully expressing their ideas without inhibition. The technology effect is used to support instant formative feedback and interactions among students effectively.

A Professional Learning Experience for Pre‐service and In‐service Teachers and One Teacher Educator: reflections and lessons learned

Abstract

In this paper we reflect on our efforts during the 1992–93 academic school year to create a different type of teacher education experience — one based on active learning, and collegiality and mutuality. Drawing on a model for classroom‐based teacher development described by Thiessen (1992), we begin with an overview of how we worked to (a) improve the quality of learning for all participants; (b) create a supportive learning environment for all the stakeholders; (c) leant in the complex and changing situation of classroom life; (d) combine personally meaningful, educationally defensible and socially justifiable evaluation practices; and (e) engage in reflective, interactive and transformative experiences. After this we. describe tension we experienced, which resulted from a lack of shared vision among us and from our efforts to examine our own practice. We also explore how we tried to deal with the tension. We conclude with lessons learned from our experience which have led to new questions about teacher education reform.     

Construction and validation of a Chinese SRL-based reading instruction questionnaire

The purpose of the study is to construct and validate a Chinese self-regulated learning (SRL)-based reading instruction questionnaire (CSRIQ) and to examine the relationship between Chinese reading instruction and Hong Kong students' reading development from the SRL perspective. A total of 339 Grade 10 students completed the initial CSRIQ in Study 1. Exploratory factor analysis and reliability analyses were used to assess the psychometric quality of the questionnaire, and the original CSRIQ subscales were then revised. Study 2 comprised 1,121 Grade 10 students. The factor structure of the revised CSRIQ was supported by the findings of confirmatory factor analysis. The findings of structural equation modelling indicated significant relations between SRL-based instruction and various reading-related variables. Among the four aspects of instruction, teacher support was the most positive factor facilitating Chinese students' reading development, whereas student autonomy seemed less favourable. Cultural and curricula factors affecting Chinese reading instruction in Hong Kong were discussed.     

Impact of the Public Library District Model on Local Funding of Public Libraries in New York State

For more than a decade the Regents of the State of New York have recommended that public and association libraries in the state become public library districts with independent taxing authority. The Regents contend that such districts are preferable for several reasons, in particular for more reliable and higher per capita funding for library services. This study, using data provided by the New York State Education Department, examined the funding of all public libraries in New York during a ten-year period. The study found that while public library districts did demonstrate more reliable funding over time, they did not see improved per capita funding as compared to other library types found in the state.
