| Under the traditional teaching method,the course of "Medical Chemistry Foundation" in secondary vocational schools can give full play to the leading role of teachers and impart a large amount of systematic knowledge to students in a short period of time.However,there are also problems such as emphasis on knowledge transfer and neglect of students’ ability training,which makes students’ learning efficiency low and unable to obtain comprehensive development under input-based learning.Therefore,under the reform and advocacy of the relevant policies of secondary vocational education such as " work-integrated learning,teaching by doing,learning by doing ",and combined with the secondary vocational students’ learning situation and characteristics,this research puts forward a teaching model of "staking student development as the center and output-based learning as the main".This research is based on the characteristics of experimental projects in the teaching content of the course " Medical Chemistry Foundation" in secondary vocational schools.And the project teaching method is introduced into the teaching of this course.At the same time,considering the learning characteristics of secondary vocational students’ weak basic knowledge of chemistry,the PAD classroom is integrated into the project Teaching method to reduce the difficulty of students’ independent inquiry learning,thus innovatively constructing the project-based and PAD class teaching model based on the course of " Medical Chemistry Foundation " in secondary vocational schools,and applying this model to the course of " Medical Chemistry Foundation " in DLWS to conduct research on teaching reform practice.The main content of this research includes the following aspects: First,analyze the reasons for adopting the project-based and PAD class teaching mode in the "Medical Chemistry Foundation " course in secondary vocational schools through the research of the research background,and then use the literature research method to read and summarize a large number of Relevant literature analyzes the current research status and existing shortcomings to lay the foundation for follow-up research.Second,on the basis of literature research,the paper defines the concepts of the PAD classroom,the project-based learning,the project-based and PAD class teaching mode,and further analyzes the theoretical basis of the project-based and PAD class teaching mode as constructivism learning theory and humanism learning theory.Third,using the literature research method and taking DLWS as the observation and survey object to analyze the curriculum characteristics,teaching status and the foundation of the action research of " Fundamentals of Medical Chemistry ",and then based on the above survey and analysis results to construct the project-based and PAD class teaching mode of the course of "Medical Chemistry Foundation" in secondary vocational schools.Fourth,choose DLWS as the object of action research to carry out teaching design and teaching practice according to the constructed teaching model.After each teaching practice,the teaching effect evaluation analysis and teaching reflection are carried out to continuously improve and perfect the teaching mode.Through action research,it is shown that the project-based and PAD class teaching model centered on student development can stimulate students’ intrinsic motivation and interest in learning,and at the same time allow students to deeply internalize and absorb knowledge points in the process of multiple output of knowledge,which effectively improves The grades and learning efficiency of the students of the " Medical Chemistry Foundation " course in secondary vocational schools,in addition,the impartation of knowledge is organically combined with the cultivation of students’ independent learning ability,communication ability,language expression ability and team cooperation ability,as well as the cultivation of phenomenon observation and law cognition,experimental exploration and innovation consciousness,scientific attitude and social responsibility of chemistry core literacy,which promotes the all-round development of students. |
