运用“领视定格”技评方法对学生铅球技术考核的实验研究

Application of Technical Assessment Method of "Leading Observation and Freeze-Frame" in General Course of Students Shot-Put Techniques Examination

采用实验对比法、数理统计法等,分析教师运用领视定格方法进行铅球技评教学的内涵。先后制定了技评内容、指标、给分原则、细则方式,并在各档次分值中配以技术动作示意图和动作规格,以及要求的简练明确的词语。对数据统计结果的分析表明,实验组高分差段百分率明显下降,密度向低分差区密集,打分差距在缩小,说明"领视定格"技评方法具有评分较为准确、方法比较简便等优点。

The authors conducted a research on the application of the technical assessment method of ＂leading observation and freeze-frame＂ for teachers in the course of students＇ shot-put technology examination by adopting comparative experiment and mathematical statistics. The authors have formulated a technical assessment content, indicators, score principles, ways of detailed rules, and provided the technical diagrams, clear and concise action specifications and requirements at all grade scores. The results indicated that high scores difference paragraph of experimental group declined significantly, density crowded together to the low score areas, spatial difference of scoring already narrowed. The results show that the technical assessment method of ＂leading observation and freeze-frame＂ has more accurate, simple advantages in the technique examination.
