Effectiveness of the Slide and Cross-Over Steps In Volleyball Blocking—A Temporal Analysis     

Richard H. Cox  Larry Noble  Robert E. Johnson 《Research quarterly for exercise and sport》2013,84(2):101-107

Abstract

Three initial step techniques for moving laterally are commonly used by middle blockers in volleyball. These three methods are (1) the slide step, (2) the cross-over step, and (3) the jab cross-over step. The purpose of the current investigation was to study the relationship between the three initial step techniques and selected time variables involved in the jumping and blocking action. Four criterion measures were extracted from film footage (100 frames/sec) using cinematographic data collection techniques. Six skilled volleyball players were used as subjects (3 men and 3 women). A split-split plot 3 (step method) × 2 (response direction) × 2 (sex) factorial design, with repeated measures on method and direction, were used to analyze the criterion measures. Results of the analysis revealed a clear relationship between step method and three of the time variables studied. Specifically, the cross-over steps (and in particular the jab cross-over) were observed to be superior to the slide step in terms of getting the athlete's body off the ground and into a blocking position quickly. While earlier investigations demonstrated that the slide step was superior in terms of getting from a middle blocking position to a floor switch mat (stationary target) it seems clear from the present investigation that the jab cross-over is superior in terms of actual jumping and blocking efficiency.  相似文献   

Pre-service teachers’ perceptions of effective inquiry instruction: are effective instruction and effective inquiry instruction essentially the same?     

Mark W. Aulls  Ahmed Ibrahim 《Instructional Science》2012,40(1):119-139

This multiple case study examined pre-service teachers perceptions of effective post-secondary instruction. Pre-service teachers were asked to write essays describing an effective teacher of their choice. Twenty-one essays were randomly selected. Data analysis involved open coding of each essay, content analysis of each essay using Anderson and Burns’ (Research in classrooms: The study of teachers, teaching, and instruction (1st ed.). Oxford, England; New York: Pergamon Press, 1989) empirically derived dimensions of instruction, and effect size analysis of student and teacher roles. Instructional components were identified that differentiate between effective inquiry instruction and effective instruction. Effective inquiry instruction was associated with more and different teacher and student roles, more activities as part of instruction, and more student small group discussion than was effective instruction.  相似文献

Oral versus written assessments: a test of student performance and attitudes     

Mark Huxham  Fiona Campbell  Jenny Westwood 《Assessment & Evaluation in Higher Education》2012,37(1):125-136

Student performance in and attitudes towards oral and written assessments were compared using quantitative and qualitative methods. Two separate cohorts of students were examined. The first larger cohort of students (n = 99) was randomly divided into ‘oral’ and ‘written’ groups, and the marks that they achieved in the same biology questions were compared. Students in the second smaller cohort (n = 29) were all examined using both written and oral questions concerning both ‘scientific’ and ‘personal development’ topics. Both cohorts showed highly significant differences in the mean marks achieved, with better performance in the oral assessment. There was no evidence of particular groups of students being disadvantaged in the oral tests. These students and also an additional cohort were asked about their attitudes to the two different assessment approaches. Although they tended to be more nervous in the face of oral assessments, many students thought oral assessments were more useful than written assessments. An important theme involved the perceived authenticity or ‘professionalism’ of an oral examination. This study suggests that oral assessments may be more inclusive than written ones and that they can act as powerful tools in helping students establish a ‘professional identity’.  相似文献   

Methods matter: Improving causal inference in educational and social science research: A review article     

Eric R. Eide  Mark H. Showalter 《Economics of Education Review》2012

Professors Richard J. Murnane and John B. Willett set out to capitalize on recent developments in education data and methodology by attempting to answer the following questions: How can new methods and data be applied most effectively in educational and social science research? What kinds of research designs are most appropriate? What kinds of data are needed? What statistical methods are best used to process these data, and how can results be interpreted so that policymakers are best informed? In this review we summarize main contributions of the book, assess the unique value-added of the text, and discuss the usability of it to various potential audiences.  相似文献   

A New Perspective: The Common Factors Model as a Foundation for Social Work Practice Education     

Mark Cameron PhD  Elizabeth King Keenan 《Journal of Teaching in Social Work》2013,33(3):346-358

Foundation social work practice education is critical to the preparation of BSW practitioners for professional practice and the establishment of a theoretical and skill base upon which graduate students may build competencies in the advanced curriculum. Issues in the foundation practice curriculum may hinder this development. The common factors model holds promise as an organizing framework for foundation social work practice education. This model may help to resolve some key issues in social work and social work education, and may provide a useful, coherent, and empirical base for the foundation practice curriculum.  相似文献   

Research on Webbed Connectivity in a Web-Based Learning Environment: Online Social Work Education     

Dorinda Noble  Amy Catherine Russell 《Journal of Teaching in Social Work》2013,33(4-5):496-513

This paper describes the preliminary data and analysis of how students in an online MSW program perceive their experiences, interactions, and responses to learning structure, material, and technology in the Web environment. The student perceptions, which have been used to refine the online program, highlight how important it is to students to feel a personal or webbed connection to faculty and other students in the Web environment. Rather than being a cold, sterile learning environment, the online learning world appears to be one that encourages professional webbed connectivity and relationship building.  相似文献   

Using Intensive Interaction to add to the palette of interactive possibilities in teacher–pupil communication     

Mark Barber 《欧洲特需教育杂志》2013,28(4):393-402

Intensive Interaction was introduced to a special developmental school in Melbourne, Australia. The school had previously used behavioural and skills‐based teaching approaches to underpin the teaching of students with severe/profound intellectual disabilities and autistic spectrum disorders. Video baselines of students involved in classroom interactions were taken before introducing the approach of Intensive Interaction to the school. Following a 30‐week period during which the approach was practised routinely in classrooms, further video records were made. These video records enabled comparison to be made against five indicators of student involvement. Professional development using video techniques and structured reflection was initiated with all involved staff. Increases in the student’s joint focus, positive affect and interactive involvement were noted. In addition to changes in the communicative involvement of the pupils, the practitioner’s communicative involvement was also noted to change.  相似文献   

The effect of activity type on the engagement and interaction of young children with disabilities in inclusive childcare settings   总被引：1，自引：0，他引：1  

Coral Kemp  Yuriko Kishida  Mark Carter  Naomi Sweller 《Early childhood research quarterly》2013

The engagement and adult and peer interaction of 37 young children with a range of disabilities was measured in free play, group, and meal-routine activities in inclusive childcare settings. A significant effect for activity type was found for total engagement, active engagement, and passive engagement, with the children being more engaged in free-play and meal-routine activities than group activities. Free-play and meal-routine activities provided better opportunities for active engagement than did group activities, but children were more actively engaged during meal-routine activities than during free play. Passive engagement was more commonly observed during group activities. Children interacted more with their peers during free play. When children with a diagnosis of autism spectrum disorder were compared with children with other disabilities, they were found to be significantly less engaged during free play and interacted less with their peers. The implications of these findings for inclusive practice in childcare settings are discussed.  相似文献
