Research On OMO Teaching Mode Based On "SPOC+PAD Class" In The Teaching Action Of Fundamental Theory Electrical Engineering In Secondary Vocational Schools

With the continuous development of information technology,the application of information education is becoming more and more popular.In the face of the normalization stage of epidemic prevention and control,the teaching reform of secondary vocational schools is imminent.The single traditional teaching mode does not conform to the current situation.It is necessary to adopt offline and online integration(OMO)diversified teaching to cultivate modern skilled and high-quality workers and talents.Through the current hot spot of teaching research,online teaching is represented by SPOC teaching.Although it can well guarantee learners’ autonomous learning experience before class,the interaction between teaching and learning is insufficient,and it is difficult to fully master all knowledge points.Offline teaching is represented by PAD Class.Although the split classroom can make the classroom more student-centered,give students half of the time in the classroom,and let students internalize and absorb after class,However,the lack of necessary pre-class preparation will inevitably affect the teaching quality,so it is an attempt to combine SPOC with PAD Class to conduct online and offline integrated teaching action research.Based on the analysis of relevant research on SPOC,PAD Class and OMO at home and abroad,guided by constructivist theory,cognitive discovery theory,humanism theory and deep learning theory,this paper uses literature research,investigation research and action research methods.The specific research includes the following four parts:First of all,by combing the current situation and theoretical basis of SPOC,PAD Class and OMO teaching at home and abroad,the research ideas and steps for teaching basic electrical courses are established;Secondly,according to the theoretical basis and the current situation of teaching mode design,the OMO teaching mode of SPOC+PAD Class is constructed,and the situation of learners is analyzed through questionnaire survey.At the same time,the teaching objectives,teaching content and teaching environment are analyzed to determine the feasibility of this course to take this teaching mode for action research.Secondly,the SPOC platform selection,teaching process design Teaching evaluation design and teaching resource design.Finally,according to the teaching arrangement,three rounds of action research were carried out with superposition theorem,RL series circuit and three-phase AC load circuit.Through observation,teaching evaluation and implementation of questionnaires,the existing problems in each round were optimized to achieve the desired effect.Finally,the deficiencies of the research were pointed out through questionnaires and interviews,and the outlook was put forward to provide suggestions for the follow-up basic electrical teaching researchAfter three rounds of action research,the conclusions of this study are as follows:(1)The use of SPOC+PAD Class OMO teaching mode in the basic electrical engineering course is conducive to improving the enthusiasm and initiative of secondary vocational students;(2)The use of SPOC+PAD Class OMO teaching mode in basic electrical engineering courses is conducive to improving vocational students’ professional ethics and knowledge mastery;(3)The use of SPOC+PAD Class OMO teaching mode in basic electrical engineering courses is conducive to improving the practical and innovative abilities of secondary vocational students.
