An Analysis Of The Influence Of Variation-imagery Method On University Students Technical Skills And Sense Of Rhythm In Learning Aerobic Excercises

Aerobic exercises cover a wide range of physical education, literature and arts, dancing, aerobics as well as music. Using physical activities as its content, artistic creation as its expressive device, and centering on musical rhythms, it involves rhythmic movements of every part of the whole body. With a combination of variations in intervals, strengths, tempos, and energies of the movements concerned, aerobics exercises are intended to achieve the aesthetic effect of fitness, force and beauty of the human physical activities. However, in many years'actual teaching practice, the students could not grasp and perform the basic techniques in aerobic exercises to satisfaction when conventional teaching methodology was adopted. The aesthetic effects of 'fitness'and'beauty'of aerobic exercises could not be well achieved. With the constant and ever-advancing development of colleges and universities, the P. E. teaching methodology in our university is also supposed to be innovated and keep pace with the new development.The method of variation-representation discussed in the thesis means to introduce the training on psychological movements into the teaching of aerobic exercises.This method works the following way: After the teacher has performed a complete set of standard actions, through guiding and reminding students of the suggestive meaning of language and the changing musical rhythms, the students are taught to recall and resurface the accurate movements and actions in their minds. Then the cognized actions are represented and visualized in accordance with the changing rhythm of the music so that students may accelerate in grasping the related techniques and skills and their performance can be considerably improved.The subject in the research consists of 90 female students enrolled in 2008 in Inner Mongolia Agricultural University who have chosen aerobic exercises as their selective course. The researching technique used is grouping-teaching and experimentation. Subjects are divided into three groups at random, including the experimental group and two control groups. Through a semester of 15 week-long teaching experiments, thepsychologicalmeter and the rhythm test are adopted to test students'general representation ability and sense of rhythm in the three groups. Moreover, statistical analysis is applied in the evaluation and grading of students'final performance of aerobic exercises at the end of the semester.1. When tested with t test, as far as students' performances (technical skills of the acquired aerobic movements)are concerned, those in the experimental group are much more satisfying than their counterparts in the two contrastive groups.2.When tested with variation-image capability on the acquired aerobic movements before and after the method is adopted, the image-representing capability of the experimental group is much more satisfying than that of the contrastive groups.3. When tested on students'sense of rhythm before and after the method is adopted, significant differences are found and the sense of rhythm among students of the experimental group is much better than that of the contrastive groups.4. A teaching method that combines the variation-image method with traditional method proves much more effective than the regular teaching pattern of aerobic exercises. It can serve as one of the feasible ways to efficiently improve and promote the teaching results.5.In real practice and drilling of the aerobic exercises, the result is much more satisfying when variation-image method is adopted than otherwise.
