| Under the environment of "Internet +",the wide application of emerging information technology in the field of education promotes educational informatization,which brings the innovation of educational idea and the reform of teaching model.The blended teaching that introduces information technology into the whole process of teaching and learning has reintegrated all elements of the teaching process,making online teaching and traditional classroom teaching complement each other and being more and more favored by teachers and students.As a core and main course of chemical engineering major in higher education,the content of Chemical Reaction Engineering not only involves a wide range of theoretical knowledge,but also covers a lot of engineering practice,which plays a very important role in cultivating students’ engineering analysis ability and engineering practice ability.Therefore,this study decided to explore an effective blended teaching model of Chemical Reaction Engineering under the "Internet +" environment,aiming to promote the high input and high output of the study of Chemical Reaction Engineering through the reform and optimization of teaching and learning activities.Firstly,This study adopts the method of literature research to analyze the research status of blended teaching at home and abroad and define the concepts of "Internet +" and blended teaching.And based on Bloom’s theory of classification of cognitive objects,new constructivist learning theory and the theory of connectionism,this paper expounds the design points of blended teaching in detail.Secondly,The author further carried out preliminary analysis from three aspects: the basic situation of learners,the status of classroom teaching and the theory of blended teaching reform.The analysis results indicate that learners have problems with low learning interest,weak self-control and less learning input.And there are some problems in classroom teaching,such as lack of students’ subjective status,low participation in classroom interaction,insufficient cultivation of engineering practice ability and innovative spirit.Thirdly,the author makes a goal-oriented design and analysis of the Chemical Reaction Engineering,aiming to clear the teaching objectives,content modules andoverall assessment process of the Chemical Reaction Engineering,which lays a foundation and direction for the design of blended teaching model.After that,the author designed a blended teaching model of Chemical Reaction Engineering in the "Internet +" environment from four dimensions: blended teaching environment,activities,methods and evaluation.Further more,the author chose the chapter 5 of Chemical Reaction Engineering to apply this teaching model to real teaching environment.The comparative experiments,questionnaire methods and interview methods were adopted to test the teaching effect and student satisfaction of this model.The results show that the teaching effect of the blended teaching model is better than that of the traditional teaching model,and the students are more satisfied with the blended model.The study also found that compared with the traditional model,the blended teaching model has four advantages :(1)improving students’ learning enthusiasm and consciousness;(2)improving students’ participation in class and promote the dynamic generation of class;(3)enhancing students’ learning depth and promoting their knowledge output;(4)developing students’ engineering practice ability and innovative spirit. |
