Study On Application Of Case Teaching Method In Soil And Fertilizer In Secondary Vocational School

In recent years,the national policy actively promotes talent cultivation and teaching reform in vocational education,and the reform of teaching methods is significant in the teaching of vocational education.As an interactive and open teaching mode,the case teaching method is popular among teachers and students.The course of "Soil Fertilizer" in secondary education emphasizes both the learning of basic theoretical knowledge and the application in practical production,and the application of case teaching method in this course meets the demand of teaching reform in vocational education.Based on this,firstly,we interviewed the teachers to understand the application of case teaching method in "Soil Fertilizer" course,and learned from the interview results that the teachers mainly applied lecture method in teaching,and the teaching evaluation was single,and the teaching effect was not satisfactory,so the teachers hoped to apply case teaching method in this course to change the status quo;secondly,the questionnaire of the intention of the case teaching method was distributed to the students of classes 1,2 and 3 of Landscape Technology in Class 2021,and it was learned that the students had an expectant attitude towards it;finally,the feasibility and relevance of the case teaching method applied to "Soil Fertilizer" in secondary vocational schools is analyzed.Based on constructivism learning theory,humanism theory and situational learning theory,and following the principles of authenticity,subjectivity and cooperation,the teaching process idea of the case teaching method is determined.The design and implementation of the case teaching method are respectively demonstrated by taking "soil water regulation" and "soil ventilation regulation" as examples.The specific teaching process is divided into pre-class preparation,classroom implementation and post-class stage.In the pre-class preparation stage,the teacher needed to determine the teaching objectives,select and organize the cases and write the teaching design,and the students needed to determine the group assignment and study the cases carefully.In the classroom implementation stage,four cases are selected and organized for the two contents,and the classroom implementation is completed through five steps: case presentation,case analysis,case problem,case discussion and case summary.In the post-lesson stage,teachers evaluated the teaching effect through the case summary report form filled by students,and students evaluated the learning effect through the student self-evaluation form and the group members’ mutual evaluation form;on the other hand,teachers reflected on the shortcomings of their teaching through the students’ classroom performance and the case summary report form filled by students,and students reflected on whether they had mastered the important and difficult points of teaching in the process of filling in the evaluation forms.The effectiveness of the application of the case teaching method in the middle "Soil Fertilizer" was evaluated through interviews with teachers and satisfaction surveys of students.From the good degree of class participation,good effect of teaching evaluation,good effect of teaching implementation and good effect of personal ability exercise,we can know that the implementation of the case teaching method is recognized by most students and can effectively improve the teaching effect of "Soil Fertilizer",and at the same time,suggestions for the application of the case teaching method can also be derived.In summary,the development of this study can provide reference for the practice of case teaching method in the teaching of "Soil Fertilizer" course for secondary teachers,and also enriches the research related to case teaching method in agriculture and forestry courses.
