Research On Evaluation Index System Based On High School Mathematics Network Teaching Video Resource

With the development of network technology,there are more and more video resources in network teaching,and online learning has become a more convenient and fast learning method,but the quality of network teaching video is not uniform.Therefore,it is necessary to establish the evaluation index system of network teaching video resources,which provides a certain standard for the development and design of teaching video resources.However,there are some problems in the evaluation index system of network teaching video resources.High school mathematics is a difficult and important subject,so this research combines the characteristics of high school mathematics subject,the psychological anxiety problem of high school students learning mathematics and the evaluation index of network teaching video resources.The problems existing in the system have drawn up a sound and practical evaluation index system of high school mathematics network teaching video resources,hoping to provide a certain understanding function for the development of high school mathematics network teaching video.The main research methods used in this paper are literature investigation,connotation analysis,questionnaire survey and analytic hierarchy process(AHP).First of all,the preliminary formulation of high school mathematics network teaching video resources evaluation indicators.Based on the analysis of the characteristics of high school mathematics,the psychological anxiety problem of high school students in learning mathematics and the evaluation index system related to network teaching video resources,the evaluation index of network teaching video resources in senior high school mathematics has been preliminarily drawn up.Secondly,revise and perfect the evaluation index.In order to improve the evaluation index of high school mathematics network teaching,experts are asked to revise the evaluation index by means of questionnaire survey,and the rationality of each evaluation index is investigated to improve the evaluation index of high school mathematics network teaching video resources.Thirdly,the weight of each index is calculated by the combination of analytic hierarchy process(AHP)and expert scoring.First,the hierarchical structure model is constructed,then the questionnaire survey is designed,and the judgment matrix is constructed.through the way of questionnaire survey,the experts' opinions on the importance of the pairwise index are investigated,and then the data results are entered into EXCEL.The maximum eigenvector corresponding to the maximum eigenvalue of each matrix is calculated,and the weight is obtained after normalization.The weighted average,which is the method of calculating the score,is also given.Got the high school mathematics network teaching video resources evaluation questionnaire.Finally,the score questionnaire is put into practice.In order to verify the validity and maneuverability of the evaluation index system,the network teaching video of high school mathematics is evaluated by using the score questionnaire.It is found that the evaluation index system of video resources in mathematics network teaching in senior high school is composed of six first-level indicators,namely,video specification,online evaluation,teaching content,teaching methods,teachers' demeanor and teaching effect.Among them,the video specification includes two secondary indexes: language specification and technical specification,online evaluation includes two secondary indicators: broadcast quantity and praise quantity,and the teaching content includes three secondary indexes: scientific and correct,complete structure and difficulty analysis,The teaching method includes two secondary indexes: teaching method and teaching means.Teachers' demeanor includes two secondary indexes: professional accomplishment and personality charisma.The teaching effect includes four secondary indexes: knowledge,ability,interest and mathematical anxiety.And the scoring standard of each index is described in detail.Finally,the conclusion of the evaluation is that the evaluation index system of high school mathematics network teaching video resources can evaluate and measure the high school mathematics network teaching video resources,which is effective and scientific.The innovations of this study are as follows: first,the evaluation index system of network teaching video resources in high school mathematics is constructed,and the evaluation index system of network teaching video resources in high school mathematics discipline is established.Second,adding mathematics anxiety is helpful for educators to pay attention to mathematics anxiety in every link,prevent and alleviate mathematics anxiety effectively,and also provide a new evaluation angle for the evaluation of video resources in network teaching.
