Research On The Application Of "Micro-course + Project-driven Method" Teaching Mode In Secondary Vocational Courses

In recent years,with the development of artificial intelligence and 5G technology application,the demand for electrical and electronic application-oriented and skillful talents in China has increased,and vocational education has played an increasingly important role.In order to improve the teaching methods and teaching quality of secondary education,this paper takes the course of "Electronic Technology Fundamentals" in secondary colleges and universities as an example,and applies the teaching mode of "micro-lesson + project-driven method" to develop a set of teaching design plan for "Electronic Technology Fundamentals".The feasibility and effectiveness of the application of this teaching mode in the course of "Electronic Technology Fundamentals" in secondary colleges and universities are systematically studied.In this study,the current teaching status of "Basic Electronics Technology" course in secondary colleges and universities was investigated by questionnaire and interview method,and the results were statistically analyzed,and it was found that there are problems such as low teaching achievement of teachers,imperfect teaching links,low interest of students in class and poor learning effect in secondary colleges and universities.In order to stimulate students’ interest and improve students’ independent learning and practical ability,a reform of teaching mode was carried out.In this study,the overall design of the "Basic Electronics Technology" course was based on the results of the survey using the "micro-lesson + project-driven method",and the unit teaching design was carried out with the "DC voltage regulator circuit" as an example.The application and implementation process of "micro-lesson+project-driven method" in the classroom of "Electronics Technology Fundamentals" are explained.It was found that the classroom atmosphere was more active,and students’ participation and enthusiasm were significantly increased in this mode.Through the investigation of students’ and teachers’ teaching practice results,it is found that the teaching mode of "micro-course + project-driven method" has great applicability to the learning and teaching of the middle-level "Electronic Technology Fundamentals" course.On the one hand,it can improve students’ interest in learning,enhance their confidence in learning,improve their participation in class and enrich their practical skills,etc.On the other hand,it can help teachers consolidate their professional knowledge,improve their competence in many aspects and enhance their professional confidence.However,there are also limitations.In view of the practical problems arising from the "micro-lesson + project-driven method" in the course of "Electronic Technology Fundamentals",the future directions of improvement are proposed,i.e.,digging deeper into the teaching materials,improving teachers’ professional ability,and designing the course projects rationally.
