Dimensions of teachers’ attitudes toward instructional television     

Bruce H. Westley  Harvey K. Jacobson 《Educational technology research and development : ETR & D》1962,10(3):179-185

Summary Responses were obtained from 50 fourth and ninth grade teachers on a 55-item test of their attitudes toward television in the classroom after 33 of them had been involved and 17 not involved in television series which introduced new ways of teaching mathematics. Intercorrelations were computed, and factors were analyzed. The resulting factor structure indicated 10 unique factors of the attitudes expressed. No general factor was found. The ten factors were tentatively identified as follows: challenge-threat, economy, instructional side-benefits, partnership between TV and classroom teachers, responsiveness, parental influences, security of the classroom teacher, invidious comparison, experimental attitude, and in-service training. On the whole the teachers’ attitudes were highly favorable to instructional television, and consistently rejected the idea that the TV teacher represents a threat to the classroom teacher.  相似文献

Role of joint torques generated in an optimised Yurchenko layout vault     

Koh M  Jennings L  Elliott B 《Sports biomechanics / International Society of Biomechanics in Sports》2003,2(2):177-190

The purpose of the study was to quantify the muscle torques required in the performance of an optimised Yurchenko layout vault based on a five-segment rigid link model and using input data from an elite female gymnast. At impact, the wrist torque trajectory indicated an extension-flexion action while the shoulder was characterised by extension. The approximate 100 Nm (wrist flexor) and 125 Nm (shoulder extensor) respective peak torque magnitudes indicated that the impact action is not passive in nature. The contribution of joint torques to the adjoining segments was apportioned to the relative components namely; centripetal, gravity and net joint torque components. Despite the presence of both large wrist and shoulder joint torques, the net turning effect on the upper limb and hand segments about their centre of mass (CM) was small. The principal role of the upper limb joint torques was therefore to effect the appropriate joint motions and to support the weight of the gymnast. The performance of the optimum vault was primarily the result of the interplay between the centripetal and the net joint torque components at the wrist, hip and shoulder joints. This has implications to the performer in that successful execution of the vault is principally concerned with the ability to create a high angular momentum for horse impact and to then apply an appropriate level of joint torques that will make optimal use of the initial kinetic condition.  相似文献   

Accuracy of qualitative analysis for assessment of skilled baseball pitching technique   总被引：1，自引：0，他引：1

Baseball pitching must be performed with correct technique if injuries are to be avoided and performance maximized. High-speed video analysis is accepted as the most accurate and objective method for evaluation of baseball pitching mechanics. The aim of this research was to develop an equivalent qualitative analysis method for use with standard video equipment. A qualitative analysis protocol (QAP) was developed for 24 kinematic variables identified as important to pitching performance. Twenty male baseball pitchers were videotaped using 60 Hz camcorders, and their technique evaluated using the QAP, by two independent raters. Each pitcher was also assessed using a 6-camera 200 Hz Motion Analysis system (MAS). Four QAP variables (22%) showed significant similarity with MAS results. Inter-rater reliability showed agreement on 33% of QAP variables. It was concluded that a complete and accurate profile of an athlete's pitching mechanics cannot be made using the QAP in its current form, but it is possible such simple forms of biomechanical analysis could yield accurate results before 3-D methods become obligatory.  相似文献
