The Design And Implementation Of Internet Plus Classroom Teaching Platform In Higher Vocational Colleges Based On HTML5

With increasingly deep integration of information technology and curriculum,Internet technology is profoundly changing education,so the corresponding teaching design is also ready to come out.At present,most vocational colleges are carrying out the teaching mode reform based on the flipped classroom concept.The teaching evaluation has a strong guiding effect on education and teaching in colleges and universities.With the flipped classroom teaching mode reform and the Internet +classroom construction as the core,the vocational college Internet + classroom teaching platform based on HTML5 is designed in the paper combined the diversified evaluation mechanism,which is applied to teaching practice.The main research work of this paper is as follows:Firstly,according to functional requirements of the Internet + classroom teaching platform,the system is divided into the online resource management,online learning,diversified teaching evaluation,exchange discussion and system maintenance.A diversified teaching evaluation model is established through determination of the evaluation index system and reasonable treatment of the evaluation results.The system demand analysis is completed adopting the use case diagram combining with functional modules to introduce functional demands in detail.Secondly,a detailed analysis is conducted for the efficiency of real-time exchange discussion and online video and its impact on the system response time.Through the analysis of online video learning time,the LIRS(the shortest recently used interval algorithm)is used for video cache.In addition,the WAST(Microsoft Web application load test tool)is used on the system for single server stress testing.Finally,the distributed technology is used to design real-time exchange discussion subsystems and online video subsystems.Thirdly,the analysis is conducted for evaluation subjects in diversified teaching evaluation,and the analytic hierarchy process is used to establish the mathematical model of the evaluation subject weight.Then,the data volume of the diversified teaching evaluation is evaluated,and the database sub-table technology is used to optimize the data storage.In the Internet plus classroom teaching platform,students can participate in the entire teaching activities with the flipped classroom teaching model to improve the autonomy of learning.Furthermore,through the diversified teaching evaluation,the student evaluation has strong direction and operability,in order to test classroom teaching effect,promote students' extracurricular prescription learning,and improve their overall quality.So,school,society,and family can participate in teaching activities together.
