| The state attaches great importance to safety education for students.The long-term goal of safety education is to popularize safety culture in the whole society,make the public establish correct safety values and promote safety ethics.However,at present,safety education is still implemented in the way of instilling knowledge mainly by teachers,and the teaching of knowledge is the main task,which leads to the poor teaching effect of safety education,and safety education teaching activities gradually become formal.Therefore,safety education for safety culture should hold the teaching concept of "student-centered and teacher-led",change from"teaching"-based to "learning"-based,and avoid the simple "In the process of teaching,we should focus on the emotional exchange between teachers and students,inspire students to question,investigate,and reflect,and pay attention to the role of emotional factors in the learning process of students.In addition,safety education needs a student-oriented teaching reform,and the teaching reform must be accompanied by a corresponding evaluation reform.Based on the above-mentioned background,this study selects the thesis entitled: Optimization of safety education course teaching based on safety culture and effect evaluation research,which is as follows:(1)Visualization study of the current state of safety educationUsing the information visualization software Cite Space,the overall trend analysis,research theme analysis and hot frontier analysis of domestic related literature were conducted respectively to understand and grasp the current situation of safety education,and to conclude that there are two problems in safety education,namely the unreasonable teaching evaluation method and the lack of safety education research from a cultural perspective.(2)Research on the optimization model of safety education teaching based on "three styles in one"The first part is the construction of the "three-in-one" teaching model.The second part is the study of the implementation strategy of the "three-in-one" teaching model,in which the heuristic teaching method can guide students to trace the essence through the cultural phenomenon;the experiential teaching method can let students understand the meaning of safety culture through experience in specific situations;the practical teaching method can develop students’ cultural practice ability.The third part is a study on the application and practice of the "three-in-one" teaching model,in which we evaluate the learning effect of students after the implementation of the teaching practice pairs and make specific teaching suggestions.We also found that the teacher’s evaluation of students’ speech behaviors is subjective,which leads to the problem of poor objectivity and low reliability of the evaluation results.(3)Research on the evaluation method of students’ cultural performance based on computer audio-visual technologyThe main research is divided into three parts.The first part is the study of the student safety culture index system,which focuses on three aspects: the determination of expressive goals,the design of expressive tasks,and the development of expressive evaluation rules.The second part proposes a student cultural expressive evaluation method based on Audio Visual Integration Temporal Convolutional Neural Network with Gate Recurrent Unit(AVI-TCN-GRU),which is used to address the current It is used to solve the problem of poor objectivity and low reliability of the current expressive evaluation,which relies too much on the evaluator’s observation and subjective evaluation of students’ performance.Finally,the AVI-TCN-GRU algorithm model was built,and the labels of the samples were obtained by collecting speech data and formulating expert scoring rules.After the model training experiments,the function of quantitative computer evaluation of students’ speech level was realized,and the tests showed that the RMSE of the evaluation index of the model was 0.34 and the accuracy rate was 0.763. |
