Research On The Application Of Case Teaching Method In The Teaching Of Plant Production And Environment In Secondary Vocational School

In recent years,China has attached great importance to the construction of a modern vocational education system and has been committed to cultivating high-quality technical and skilled personnel.Driven by the reform of vocational education teaching methods,the case teaching method,as a heuristic teaching method focusing on ability training,is widely recognized and welcomed by teachers and students in the education circle.“Plant Production and Environment” in secondary vocational school is the basic course of landscape technology major,and it is of great significance for the connection of subsequent professional core courses.Based on this,through the investigation and practice of Lanzhou X Vocational School’s secondary vocational garden technology major,this research displays the learning status and teaching status of the teaching objects.It is found that the following problems exist in the case teaching of “Plant Production and Environment” in secondary vocational schools.The content of the cases selected by the teachers is thin and outdated,and the presentation forms of the cases are rigid and simple;the classroom adopts a novel case teaching method,but is still dominated by the teacher’s teaching mode;secondary vocational students have low learning interest and weak learning ability;summative evaluation such as final grades Mainly,lack of process evaluation.In order to improve the current teaching situation,the chapters applicable to the case teaching method are determined,under the guidance of paradigm teaching theory,constructivism theory,humanistic theory and learning transfer theory,and based on the characteristics and application principles of the case teaching method.And conducted case teaching design research,and presented four case teaching designs of “plant reproductive organs(flowers)”,“water regulation of plant production”,“photosynthesis of plants”,and “temperature regulation of plant production”.The content of the design is practiced,and take the chapter “temperature regulation of plant production” in the course “Plant Production and Environment” as an example.The application process and effect of the case teaching method in the three stages of before class,during class and after class are expounded in detail.Through classroom observation,questionnaire survey and interview research results show that the rich and diverse cases increase students’ subject interest,case discussion and inquiry promote students’ expression and communication,and teachers’ professional development and students’ ability and literacy are jointly improved.Finally,it summarizes and reflects on the staged results of the research,and puts forward the following suggestions for the application and implementation of the case teaching method: 1.Pay attention to the development of cases and the construction of the case database;2.Diversified teaching modes led by case teaching;3.Improve students’ interest in learning;4.Change the roles of teachers and students,and play the main role of students;5.Establish a diversified teaching evaluation system.Prospects are put forward for the follow-up teaching research of “Plant Production and Environment” in secondary vocational schools based on the case teaching method,which provides reference for the next research work.In conclusion,this study provides a practical reference for the application of the case teaching of “Plant Production and Environment” in secondary vocational schools,and also enriches the relevant theoretical research on the case teaching method.
