| With the development of the times,information technology and the Internet have brought tremendous impact to the education industry.Mixed learning originated from such a background of educational informatization and promoted educational reform,and has become a hot spot in educational research and practice.Blended learning in the "Internet+" era has given new connotations to learning.It is not only a mixture of face-to-face teaching and online teaching,but also a new teaching model of mixed teaching and tutoring in a "student-centered" learning environment.This research takes "Internet +" as the core element,organically integrates mobile terminals,Internet and other information technologies into learning activities and courses,makes full use of teaching interactive platforms and networked teaching video resources,and creates a student-centric mixed learning environment.To achieve the educational goal of vocational education with the value characteristics of whole-person development."Automotive Structure Understanding" is a theoretical and practical professional basic course in the field of automotive manufacturing and maintenance in the field of processing and manufacturing in secondary vocational schools.The course content includes the understanding of the overall structure of the automobile,the understanding of the structure of the automobile engine,and the understanding of the structure of the chassis of the automobile.Understanding of the structure of automobile electrical equipment,understanding of the structure of automobile body,etc.Through a questionnaire survey on teachers and students in vocational schools,it is found that the traditional teaching model of the course is not conducive to improving students’ interest and ability.This article puts forward a new idea of "Internet +" hybrid learning model,and takes the design and practice of the hybrid learning model from the student-centered perspective as the entry point of research.Through the theoretical study of the hybrid teaching model,a hybrid of Internet + as a carrier is constructed.The teaching mode is verified in the classroom teaching practice of the secondary vocational school.This study used methods such as literature research,questionnaire survey,action research,and interviews.First of all,by combing and analyzing the domestic and foreign literatures,it summarizes the origin and research status of mixed learning,and makes a deepinterpretation of the connotation and characteristics of mixed learning.Secondly,it analyzes the five elements of the mixed learning model and builds a mixed learning model from the perspective of students.Thirdly,the questionnaire survey was used to analyze the current teaching situation of "Vehicle Structure Understanding" in secondary vocational schools,construct a student-centered and "Internet +" mixed learning model,and conduct the vocational course "Vehicle Structure Understanding" with the core of mixed teaching concepts Instructional design.Finally,after the teaching practice is over,the teaching practice effect of the experimental class and the control class is evaluated through questionnaire survey,action research,interview and other methods.After teaching practice,SPSS software was used to analyze the test results of the experimental class and the control class after the semester.A questionnaire survey was used to analyze the three aspects of students’ autonomous learning ability,collaborative inquiry ability,and problem solving ability.The interview method was used to understand students’ satisfaction with the understanding and learning of automobile structure and the evaluation of the current teaching model.The following conclusions are drawn: In terms of knowledge mastery,the average scores of the experimental and control classes are 80.429 and 68.427,and the standard deviations of the scores are 9.185 and 9.538,respectively.This shows that the mixed learning model improves student performance and makes students more concentrated.The mixed learning model has help learners transfer and master knowledge.In terms of ability development,from the results of personal ability evaluation,the average value of each item is greater than 3.5,indicating that the mixed learning model helps to improve students’ self-learning ability,practical ability,communication ability,expression ability,and collaboration ability.In terms of emotional experience,students and teachers have a high degree of recognition of mixed learning mode teaching,indicating that mixed learning mode helps to improve the satisfaction of students’ learning experience.Practice shows that this thesis constructs a hybrid learning model,and chooses the course of "Vehicle Structure Understanding" in secondary vocational school for teaching practice,which verifies the rationality and effectiveness of the hybrid learning model.The mixed learning model can increase the interest of secondary vocational students in professional knowledge learning,cultivate students’ independent learning ability and inquirylearning ability,and provide effective reference for mixed learning practice for vocational schools and teachers. |
