The Plan And Demonstrative Research Of The Result Estimation System For The Students Applying The General Volleyball Course

It is desired for us now to improve the estimation system of the results for the general volleyball course, to make it function as completely as possible in order to meet the requirements in society for the physical talents in future. In this article, it relates a kind of new, just, scientific estimation system which has been turned out properly through experiments. By applying it, we can justify the teaching and estimation, arise the students'interests, ensure the central position of the students and let all of them achieve ,to some extent, merits in general volleyball course. Thus, it can provide a basic data for the theoretical and practical research in this field.Here initially developed estimation system for the general volleyball course in various methods such as reference, Delphi, experiments and mathematical statistics. The system includes three first-class targets as participation, technique and ability, There are also thirteen second-class targets which can comprehensively estimate the students results. In order to make the estimation function completely, make the teaching process go smoothly and students study harder, many methods of estimation are employed such as self-estimate, other's estimate, diagnostic estimate, formal and summarized estimate. The new system is tested by the comparison and analysis of the students'results.The outcome of the experiment:(1) Analysis of the credibility.The total number of each experimental group is calculated by the relative number 0.908. The relative number of each sub-division is 0.865—0.970, statistic analysis shows that it's closely related (P<0.01), It turns out that the new system is credible.(2) Analysis of objectivity.To calculate the Kendall's concordance coefficient (w) of each testing item in the group between 0.77—0.90, it shows that the new system is quite objective.(3) Analysis of the effectiveness.By the experts'investigation and the statistical analysis, the final targets that experts approved get above the 88.5 %, furthermore, the statistical results Also proved the experts'estimation. So, the estimation system shows itself effective.(4) Analysis of the hardship.By formula P=ph+pL/2 to calculate the hardships of the each targets in test within the new system, the outcome is between 0.38—0.53, staying in the middle level.
