| With the development of information-based education,universities,middle schools and primary schools throughout the country carry out online teaching on a large-scale especially during pandemic.At present,the correlational research of online teaching is under active exploration.In order to enrich the theoretical achievements of evaluation of online teaching for high school mathematics in domestic,this study builds an evaluation index system of online teaching for high school mathematics.At the same time,according to the evaluation index system,the corresponding questionnaire to survey the situation of online teaching for high school mathematics during pandemic is designed,to guide the online teaching for high school mathematics by finding problems,analyzing causes and giving suggestions.The research questions include:(1)How to build an evaluation index system of online teaching for high school mathematics?(2)How to apply the evaluation index system of online teaching for high school mathematics?(3)Any further development of online teaching for high school mathematics during pandemic?In order to build an evaluation index system of online teaching for high school mathematics,first of all,the study consults plenty of related document literature and an evaluation criterion of online teaching for middle and primary schools across the country during pandemic by literature analysis,to know the research status and the research object is as follows:to build an evaluation index system of online teaching for high school mathematics and to apply it to investigate the situation of online teaching for high school mathematics during pandemic.Firstly,the document literature is sorted out,filtered and processed,and a framework of evaluation index system is drawn up after preliminary communication with experts;after that,using expert consultation method,the first round of expert consultation is carried out and after collecting expert opinions,to revise and improve the framework from data information involving the degree of concentration,degree of dispersion and variable coefficient for index,as well as modification of opinions;then the second round of expert consultation is carried out,resulting excellent content validity given by experts.Finally,a scientific and reasonable evaluation index system of online teaching for high school mathematics is finalized.In the application research part,the questionnaire is compiled as per the index system built,to investigate mathematics teachers facing to their students in high school.The investigation includes pretest and formal test,through pretest for item analysis,validity analysis and reliability analysis and the final questionnaire is offered by modification.The result of 1110 questionnaires by formal test has a data analysis by SPSS 23,including the research for overall status,the study based on five dimensions of the evaluation index system,the comparative study(including teaching age and age difference analysis,education difference analysis,gender difference analysis,urban-rural difference analysis,grade difference analysis,province difference analysis,etc)and attitude study.Conclusion: the Evaluation Index System of Online Teaching for High School Mathematics built by this study,a total of 5 first-level indexes(preparation and guarantee,resource utilization and scheme design,implementation of online teaching,implementation of after-school training,evaluation and feedback),20 secondary indexes,48 observation points.The evaluation index system has excellent content validity and can be used as an effective tool to evaluate the level of online teaching for high school mathematics.Optimization suggestions for online teaching for high school mathematics: new pattern of education management;new strategy of teaching implementation;new requirements of student cultivation;new mode of interaction between families and schools;new situation of balanced education;new technology of future education. |
