The influence of live- vs. video-model presentation on the early acquisition of a new complex coordination

Background: Demonstration is a widely used method in sports teaching and coaching, based on the assumption that it is more beneficial than verbal instructions or trial-and-error methods for skill acquisition. Although in teaching/coaching situations, the demonstration is usually carried out in front of the learners, in a research context, it is most often presented via a video. However, a direct comparison between these two types of model has rarely been undertaken in a motor context.

Purpose: In this study, we aimed to compare the effectiveness of the observation of a live and a videomodel for the early acquisition of a complex judo movement.

Research Design: Participants observed either a live or a videomodel executing the task. After observation, they practised for three minutes taking five trials and then performed it for analysis. This procedure was repeated three times. The form and technique of each participant's execution were evaluated using a technical score.

Main results: The results indicated a significant improvement in the task execution by the end of the practice session. However, this improvement occurred only for the video-model group between the second and third blocks of practice.

Conclusions: The video demonstration seems more effective than the live one for the early acquisition of a completely new complex coordination. This may be due to the simplification of the visual information in the former condition because of its two-dimensionality. This simplification may allow the observer to identify the more key elements that would guide him/her for the subsequent performance of the task.     

引入优化压缩思维的无线视频传感器网络路由协议

针对无线视频传感器网络能量异构普遍存在的特点,提出一种引入优化压缩思维的无线视频传感器网络路由协议,确定节点的可压缩性,在簇头节点中完成数据的稀疏以及观测,将少数测量数据发送至汇聚节点,汇聚节点通过采集节点压缩数据的测量向量,进行压缩感知解码,完成数据的压缩以及重构操作。通过蚁群算法获取无线视频传感器网络中最小成本的路径,将数据分组发送至所有邻居节点,蚂蚁依据能量水平的高低确定下一跳,从而更好的完成全网能量均衡,蚂蚁走完所有路径后,对其信息素进行计算,求出信息素的挥发带来的负反馈,给出新的带宽函数以及跳数函数,节点间通过周期性的广播路由更新分组确保路由表的正确性,在路由选择时综合分析带宽与跳数因素,有效提高了无线视频传感器网络的吞吐量。仿真实验结果表明,所提协议可有效均衡网络能耗,延长整个网络生命周期。     

影视资料在生理学教学中的应用

在生理学课堂教学中适当应用影视资料能激发学生学习兴趣,活跃课堂气氛,取得了良好的教学效果。教师应根据生理学的教学内容,甄选与之匹配的影视资料,合理安排播放时间,使其在课堂上发挥应有的效果。     

试析政党在加拿大联邦制演变中的角色表现

纵观加拿大历史,不难发现其联邦制是由集权性联邦向分权性联邦演变的,到了20世纪下半叶,甚至有人认为加拿大省所拥有的权力和地位,可能会令联合国许多主权国家感到羡慕,可见其省享有主权之大。而在省权扩大的历程中政党所扮演的角色不容忽视。

Development of students’ conceptual thinking by means of video analysis and interactive simulations at technical universities

Video analysis, using the program Tracker (Open Source Physics), in the educational process introduces a new creative method of teaching physics and makes natural sciences more interesting for students. This way of exploring the laws of nature can amaze students because this illustrative and interactive educational software inspires them to think creatively, improves their performance and helps them in studying physics. This paper deals with increasing the key competencies in engineering by analysing real-life situation videos – physical problems – by means of video analysis and the modelling tools using the program Tracker and simulations of physical phenomena from The Physics Education Technology (PhET?) Project (VAS method of problem tasks). The statistical testing using the t-test confirmed the significance of the differences in the knowledge of the experimental and control groups, which were the result of interactive method application.
