Research On Problems And Countermeasures Of Information-based Teaching In Secondary Vocational Schools

In secondary vocational schools,the combination of teaching and information technology is a very common phenomenon.Teachers and students use computer,mobile phone,tablet and other hardware devices to use software platforms such as "vocational education cloud" and "cloud classroom" for teaching and learning,which is what we usually call information teaching mode.Before class,teachers upload teaching plans,PPT,videos and other materials on the platform for students to preview before class,and students can preview the course in advance and find difficulties on the platform.In class,teachers will no longer occupy class time to teach knowledge.However,most secondary vocational schools have many problems in implementing the means of education informatization.In terms of students,most of them have poor learning autonomy and self-control,and their academic performance is generally poor.If information-based teaching mode is used,there may be mutual plagiarism and perfunctory situation;In terms of teachers,most of the secondary vocational teachers are not adapted to the use of online teaching,and the teaching efficiency and teaching effect are easily counterproductive.Some teachers will completely rely on online teaching and abandon the usual teaching methods.In terms of schools,some secondary vocational schools are not equipped with intelligent teaching equipment,or are not equipped with conditions and so on.The term "teaching" includes the dual elements of teachers’ "teaching" and students’ "learning",which is an activity of transferring and mastering social experience,with bilateral characteristics.Teachers impart knowledge,and students master knowledge is the feedback to teachers’ teaching effect,which is often reflected in classroom questioning.However,there is a problem in this process in most secondary vocational schools,that is,most students only give feedback to teachers,while a few or no teachers directly give feedback to students,which involves the problem of timely feedback from teachers.For example,when a teacher asks a student a question and the student answers it,the teacher will give the student a timely evaluation,whether it is right or wrong.Or in the usual homework and examinations,teachers timely feedback students’ homework and examinations,and make targeted guidance to the actual situation of students.The biggest encouragement for students is that teachers give timely feedback on students’ usual performance.With these problems in mind,the author uses questionnaire survey,literature research,action research and other methods to conduct practical research in a secondary vocational school,and conducts teaching design based on "Building Construction Technology",a major course of architecture in secondary vocational school,in order to explore ways to improve information-based teaching.
