Research On The Application Of Blended Teaching In Secondary Vocational Courses

The country’s promotion of vocational education informatization reform and the drawbacks of traditional teaching in the frequency converter course indicate that it is imperative to reform the frequency converter course,so as to improve students’ knowledge and skills and meet enterprises’ demand for talents in the frequency converter industry.Blended teaching mode conforms to the needs of the development of The Times,fully integrates online technology into the field of education,effectively combines the advantages of online and offline teaching modes,avoids the disadvantages of both,creates an integrated teaching mode of "online + offline",selects learning resources according to the needs of students,fully guarantees the principal position of students,and further improves the teaching effect.Secondary vocational schools as the backbone of the training of skilled personnel,it is necessary to adopt the mixed teaching mode to reform the core curriculum of the major,so as to provide reference for the change of the teaching status quo of secondary vocational schools.This study takes "cloud class" as an online teaching platform and combines traditional offline teaching to carry out hybrid teaching for frequency converter courses of electromechanical and related majors,aiming at improving teaching effect and promoting the development of students’ core skills and qualities.This study mainly includes the following aspects:Firstly,the background of blended teaching is studied,and the literature on blended teaching at home and abroad is analyzed,so as to find the theoretical support for blended teaching in frequency converter course.Secondly,this paper investigates the frequency converter course offering situation and training objectives of some secondary vocational schools in the Pearl River Delta region,and understands the current situation of students’ learning and teachers’ teaching through questionnaires and interviews.Thirdly,on the basis of sufficient preliminary investigation,supported by the principles of task-driven,interactive and student main body,guided by the cultivation of core qualities,and taking "cloud class" as the online platform,the mixed teaching design of frequency converter course is constructed.And taking the electromechanical integration 2 class of a technician college in Guangzhou as the teaching research object,the frequency converter course to carry out the teaching practice of preview before class,interaction in class,after class consolidation,after a semester of teaching practice,the results of the two classes were compared,to verify the effect of teaching practice.The research shows that: The hybrid teaching mode,which integrates online teaching and offline face-to-face teaching supported by the cloud class teaching platform,has a good application effect in the frequency converter course of secondary vocational schools.The results of the students in the experimental class are significantly higher than those in the control class.The students in the experimental class have a better grasp of knowledge and skills,and their learning interests are enhanced,as well as their enthusiasm and initiative.Group cooperation ability,self-learning ability and other qualities have been cultivated,and comprehensive quality has been greatly improved.
