Research On Online And Offline Hybrid Teaching Practice Of Web Page Design And Production In Secondary Vocational Schools From The Perspective Of Golden Course

The online and offline mixed gold course is a course that combines the online learning platform with the traditional teaching mode according to the standard of "Two Properties and One Degree".It is the product of the reform supported by the teaching concept of "student-centered".At the same time,it has also become a research hotspot in the field of education.The construction of courses in secondary vocational colleges in accordance with the "Golden Course" standard is an important means to improve curriculum quality,an inevitable choice to achieve teaching goals,and the only way for teachers’ curriculum research."Web design and production" is a public basic compulsory course in secondary vocational schools,which is offered in the curriculum of various majors of information technology and plays an important role.Based on the current teaching situation of secondary vocational schools and the analysis of students’ learning situation,the traditional teaching model can not meet the needs of practical professional courses.From the perspective of "golden course",this paper studies the online and offline hybrid teaching practice of web design and production in secondary vocational schools,from course analysis to teaching design,from teaching practice to intelligent evaluation,combined with convolution neural network(CNN)technology,sentiment analysis is applied to the classroom for experiment and research.The main research contents and innovations include:1.The online and offline hybrid teaching design based on the golden course " Two Properties and One Degree ".In view of the problems that secondary vocational school students pay less attention to theory and practice,and there are differences in knowledge reserve,the teaching activities are divided into four stages: preheating,integration,practice and expansion,and each stage is designed to adapt to the model.from the acquisition of low-level knowledge to the design of high-level,innovative and challenging degree,it embodies the construction standard of " Golden Course ".In addition,combined with "Web Design and Production" course to construct the characteristics of the secondary vocational hybrid teaching model of " Golden Course " practice research,to verify the applicability of the teaching model.2.Real-time classroom sentiment analysis based on mini-Xception architecture.Aiming at the problems such as incomplete teaching feedback content and untimely feedback analysis,this paper puts forward the miniXception framework to realize the real-time identification and analysis of students’ sentiment in classroom teaching,and creatively brings students’ sentiment into the evaluation system of classroom teaching,so as to help teachers understand students’ learning status more comprehensively.3.S-P table analysis based on learning response information analysis.Aiming at the problems such as the stability of students’ learning and the value of test papers,the S-P table is drawn for pre-class test,classroom quiz,final exam and other test questions.According to the calculated student warning coefficient and problem warning coefficient,we pay attention to the unstable students,and at the same time,teachers reflect on the accuracy of the explanation and the rationality of the topic design.To sum up,this study focuses on information technology education in secondary vocational education,and takes secondary vocational students as the research object to build an online and offline mixed teaching model of "Golden Course" that conforms to the characteristics of secondary vocational schools,and verifies the feasibility and effectiveness of this model through the course practice of "Web Design and Production".The construction of the online and offline hybrid "Golden Course" is conducive to the implementation of personalized teaching,creatively adds a new form of classroom teaching,and plays a certain role in promoting students’ learning initiative and participation in classroom activities.The experimental results of students’ real-time sentiment analysis show that the mini-Xception model trained by FER2013 data sets has high recognition accuracy for real-time detection of students’ seven emotions,with an average accuracy of 76.29%.Compared with students’ text feedback,it can assist teachers grasp students’ learning status and respond in time,and realize the real-time performance of wisdom classroom teaching information feedback,the high efficiency of information transmission and the intelligence of information processing.The learning response information analysis method can not only analyze the overall tendency of students,but also analyze the individual characteristics of students,which is real-time,dynamic and intuitive.
