Human integration through Olympism education: a pragmatic engagement of youths in a war-torn society     

Samantha Nanayakkara 《Sport, Education and Society》2016,21(4):623-643

This paper delineates the findings of a mixed methods study that investigated how Olympism education could strengthen competencies of human integration through delivery of physical, social, and critical literacy and conflict resolution literacy. The study introduced a curriculum model integrating Olympism values and conflict resolution strategies for the purpose of facilitating human integration. This integrated curriculum model was then tested among a group of young students who represent the two main ethnic groups Sinhalese and Tamils, in a war-torn society in Sri-Lanka. The intervention of this study provided pragmatic involvement for young students as the representatives of the next generation, in order to teach them the convergence and contradictions of perceptions of social reform ideals through sport. Results revealed that conflict resolution strategies combined with Olympism education integrated curriculum intervention significantly improved young students’ conflict resolution competencies, regardless of their gender or ethnicity. This study demonstrated significant gains in the ability of young students to learn about human integration through learning about Olympism within sport and physical education lessons, in regards to effective conflict resolution.  相似文献   

Validation of the Microsoft Kinect® camera system for measurement of lower extremity jump landing and squatting kinematics     

Moataz Eltoukhy  Adam Kelly  Chang-Young Kim  Hyung-Pil Jun  Richard Campbell 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(1):89-102

Cost effective, quantifiable assessment of lower extremity movement represents potential improvement over standard tools for evaluation of injury risk. Ten healthy participants completed three trials of a drop jump, overhead squat, and single leg squat task. Peak hip and knee kinematics were assessed using an 8 camera BTS Smart 7000DX motion analysis system and the Microsoft Kinect® camera system. The agreement and consistency between both uncorrected and correct Kinect kinematic variables and the BTS camera system were assessed using interclass correlations coefficients. Peak sagittal plane kinematics measured using the Microsoft Kinect® camera system explained a significant amount of variance [Range_hip = 43.5–62.8%; Range_knee = 67.5–89.6%] in peak kinematics measured using the BTS camera system. Across tasks, peak knee flexion angle and peak hip flexion were found to be consistent and in agreement when the Microsoft Kinect® camera system was directly compared to the BTS camera system but these values were improved following application of a corrective factor. The Microsoft Kinect® may not be an appropriate surrogate for traditional motion analysis technology, but it may have potential applications as a real-time feedback tool in pathological or high injury risk populations.  相似文献

Triadic interaction in clinical task-based interviews with mathematics teachers     

Boris Koichu  Guershon Harel 《Educational Studies in Mathematics》2007,65(3):349-365

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.  相似文献
