Construction Of Risk Assessment Index System Of Swimming Class In Middle School

Swimming is known as the "king of sports",which greatly promotes the physiological and psychological aspects of middle school students,but the basic premise of swimming teaching is adequate security.There are some ways to understand the possible risks in the classroom.The construction of risk index system of swimming lessons in middle schools is of great significance for understanding the risks of swimming lessons in middle schools,which can realize the identification of teaching risks.Reduce the risk rate of swimming class and ensure the normal order of swimming class teaching.In this study,through literature review,on-the-spot observation,questionnaire survey,expert interview and mathematical statistics and other research methods,the theoretical and empirical research on the construction of risk assessment index system of swimming lessons in middle schools was carried out.Finally,the following conclusions are drawn:（1）The primary evaluation indexes are screened by Delphi method,and then the risk evaluation index system of middle school swimming class is obtained（see Appendix E）.The two dimensions of "internal risk" and "external risk" are determined as the first-level indicators.Teachers’ risk factors,students’ risk factors,full-time lifeguards’ risk factors,environmental risks and school management risks are secondary indicators.It is subdivided into 13 third-level indicators and 43 fourth-level indicators.And the effectiveness of the index system is analyzed.（2）The weight of middle school students’ swimming risk assessment indicators,the external factors and internal factors are equivalent in the first-level indicators,and the environmental risk takes the largest weight in the second-level indicators,followed by teacher risk and student risk;The third-level indicators are site management risk,hardware risk and teachers’ risk awareness,followed by students’ cognitive ability and teachers’ teaching ability.Teachers’ understanding and attitude towards risk are the most important factors in the four-level index weight,and the index weight tends to be similar with the refinement step by step.（3）The risk assessment index system of swimming lessons in middle schools constructed in this study can objectively evaluate the selected empirical objects,and according to the scores,it can be judged that the main shortcomings of the empirical objects lie in the large difference of teachers’ level and small financial support.Therefore,the risk assessment index system of swimming lessons in middle schools constructed by this study is feasible and scientific.
