Research On Application Of Problembased Learning Teaching Method In PA Course Teaching In Secondary Vocational Schools ——Take YNSQGY School As An Example

In the Implementation Plan of National Vocational Education Reform and the Action Plan for Improving the Quality and Quality of Vocational Education（2020-2023）,it is pointed out that the mode of running schools and teaching methods of vocational technical education should be reformed and innovated,the quality of teaching should be comprehensively improved,and the cultivation of vocational education talents should be actively promoted Pharmaceutical analysis is one of secondary vocational core course for students majoring in pharmaceutical production technology Integrating theory with practice,the effectiveness of classroom teaching to a certain extent affect the quality of talent cultivation.But from the point of the teaching of secondary vocational schools,the curriculum is still using the traditional teaching method as the main teaching method.Although it can teach knowledge,students’ learning efficiency is generally low.This is insufficient to cultivate the ability and improve the corresponding skills of secondary vocational students.Problem-based Learning（PBL for short）is one of the hot spots in global education research.Scholars have carried out effective researches on its connotation and extension,pointed out that this teaching method can cultivate and improve students’ comprehensive ability.Therefore,we constructed the teaching structure and process of PBL teaching method which might be suitable for secondary vocational education,and carried out practical application research on it in the course of "Pharmaceutical Analysis" in a secondary vocational school,Kunming,to explore its feasibility and effect.Firstly,on the basis of the original research,the PBL teaching method was defined,and the theoretical basis of the teaching method was analyzed.The feasibility and necessity of applying PBL teaching method to the course of Drug Analysis were discussed by the survey results of teaching status and students’ basic information.Secondly,by grasping the characteristics of students and the content of teaching materials,the teaching structure and process of theoretical and experimental courses were constructed by referring to previous studies.The contents of several theoretical and experimental courses were also selected to carry out teaching practice.We chose theory section "injection" and experiment section "tablet disintegration time limit and the difference between the weight of the check experiment" as examples to expand the application to implement the teaching process in detail.Teaching content,learning situation analysis,teaching goal formulation and selection of teaching resources were discussed in detail.Finally,a comprehensive analysis of the early and late teaching results of students,the feelings of students in the questionnaire survey and the classroom observation of students,has been summarized.It was found that implementation and application of the PBL teaching method can stimulate students’ interest in learning,promote students to develop good study habits,improve problem processing ability and the ability of cooperation and communication.It also improve the students’ classroom participation.Therefore,PBL teaching method is effective in secondary vocational education.
