Curriculum Design And Practice Of Secondary Vocational CNC Processing Technology Based On OBE Concept

With the in-depth reform of national vocational education,the demand for curriculum design is becoming bigger and higher,which has attracted the wide attention of educators in secondary vocational colleges.At the same time,the rapid development of manufacturing industry,CNC technology as one of the core technologies in the field,for the training of CNC professional skills personnel has also been the attention of the country,most enterprises for the increasing demand for talents.Therefore,secondary vocational schools also pay more attention to the innovation of CNC professional courses and the training of skilled talents.Based on this,in the investigation of numerical control teaching status,the main problems are: students 'weak skills,can not reach the practicability of knowledge;students' low interest in learning,lack of initiative,resulting in students 'learning aimlessly,poor sense of knowledge;students' comprehensive professional quality limited development,and the job of talent ability.Based on OBE concept,OBE concept solves the problems in the teaching in other teaching.The main contents of the research are as follows:(1)study the curriculum theory and development status based on OBE concept.Starting from the research background of the project,find the relevant literature to conduct the theoretical analysis of the article,and integrate the research theory and course design research path of this paper.(2)Carry out the analysis of the course design requirements,based on the OBE concept.Through the questionnaire survey of teachers and students,the teaching status and existing problems of CNC processing technology in secondary vocational schools are summarized,and the necessity of curriculum implementation based on OBE concept is found.(3)Design the curriculum system based on the OBE concept.According to the questionnaire survey results of teachers and students,the curriculum objectives,curriculum design path and curriculum evaluation system based on OBE concept are constructed,and the teaching effect of the curriculum design based on OBE concept in secondary vocational CNC majors is verified through the final teaching feedback and questionnaire survey results analysis.The following results are obtained:(1)the course design system based on OBE concept is feasible and effective and improves their practical ability;(2)the course breaks the inherent learning method,stimulates students' curiosity,increases interest in knowledge and skills,and independent learning ability;(3)meets the needs of talents and improves their professional quality.Therefore,this paper verifies that the curriculum design of secondary vocational CNC processing technology based on OBE concept is feasible and meets the development needs of the school and the society,and can also provide certain reference and reference significance for the subsequent research.
