Construction And Application Of Task-driven Flipped Classroom Teaching Mode For Secondary Vocational CNC Lathe Programming And Operation Course

Numerical control lathe programming and operation is a professional core course of numerical control technology application specialty in secondary vocational school.The investigation shows that the theory and practice of this course are taught separately in some secondary vocational schools.Due to unreasonable class hour allocation,single teaching method,abstract and boring curriculum content,secondary vocational students with weak foundation are not good in learning quality and effect.In view of the above problems,according to the learning situation of secondary vocational students and the characteristics of the course,the construction of a new teaching mode,in order to improve the teaching effect and quality of the course.This study "task drive" and "flip" class as the research object,combined with literature research,questionnaire,interview method,such as research methods,finishing the task driven and flip classroom related literature,investigation and analysis of the secondary vocational nc lathe programming and operation course teaching,the students learning,curriculum goal,curriculum content,schedules are analyzed research,selected the network teaching On this platform,a task-driven flipped classroom teaching model of CNC lathe programming and operation course for secondary vocational schools was constructed.This kind of teaching mode with "teachers,the students" education philosophy and "effectiveness" as the guiding ideology,teaching to "task drive" and "flip" class effective combination of internal structure,reset the course on network teaching platform,in the form of task transfer knowledge before class,class knowledge internalization,after-school knowledge promoted three phase coherent body,the cooperation between teachers and students to teach Learning tasks.In this study,screw shaft machining is taken as teaching practice case,and comparative teaching is carried out in class 1 and class 2 of grade 20 numerical control in a technical school.Through a semester of teaching practice,it is verified that this teaching mode can not only stimulate students' learning interest to a certain extent,solve the problems of poor learning initiative and waste of class time,but also exercise students' abilities of independent learning,communication and problem analysis,and finally improve the teaching effect and quality effectively.
