Research On The Application Of Blended Teaching Mode In Graphics And Image Processing In Secondary Vocational Schools

Traditional teaching mode faces many challenges.Students often need help with inattention and low enthusiasm for learning.Against this background,a blended teaching model emerges.Hybrid teaching mode uses the combination of online and offline,makes up for the shortcomings of traditional teaching mode,has the advantages of sharing teaching resources,flexible activation of learning time and space,and diversified evaluation methods,and helps to realize the positive cycle of teacher-student integration two-way teaching and improve teaching efficiency.Based on the blended teaching mode,this paper uses the online platform of Learning to construct the teaching model of the Graphics and Image Processing course in secondary vocational schools by combining the course characteristics and teaching status.It explores the application effect of this model in practical teaching.Firstly,based on the analysis of the blended teaching mode,a questionnaire survey was conducted on students’ learning status of Graphics and Image Processing,and teachers’ teaching status of Graphics and Image Processing was interviewed.This study analyzes the feasibility of applying mixed teaching mode to the Graphics and Image Processing course in secondary vocational schools.Secondly,based on the nature of the course and the students’ learning situation,analyze the adaptability of the blended teaching mode to the Graphic and Image Processing course,construct a teaching model for the Graphic and Image Processing course in vocational schools,and design teaching accordingly.Taking the sections Adding Characters in Landscape Photos and Design of Packaging Boxes as examples,analyze the teaching objectives and students’ learning foundation,and complete the design of course activities and evaluation methods.Before class,the teacher will upload the learning resources to the Superstar Learning Pass,and the students will preview and complete the task according to the teacher’s requirements.In the class,teachers refine the teaching content,focus on the essential and challenging knowledge,compress the time of explanation and demonstration,and leave more time for students to practice to cultivate students’ practical ability.After class,teachers upload assignments and course videos to help students consolidate their knowledge promptly.Finally,a controlled experiment was conducted on first-year students majoring in computer application at a secondary professional school in Lanzhou,and three teachers of Graphics and Image Processing were invited to attend the lecture to explore the influence of blended teaching mode on students’ learning interest and learning effect.Based on students’ classroom performance,case completion,teacher interview,and student questionnaire in the blended teaching mode,the advantages and disadvantages of applying the blended teaching mode in Graphics and Image Processing are summarized.The results show that the blended teaching model helps improve the teaching effect of the Graphics and Image Processing course in secondary vocational schools.Teachers upload learning resources to the Superstar Learning Pass,which helps students to learn before and after class anytime and anywhere.It also allows teachers to know students’ learning situations and make targeted explanations in class to leave more time for students to practice.The questionnaire and interview results show that students’ interest in learning has been improved,their learning efficiency has been improved,their learning motivation has been more vital,their thinking ability and expression ability have been exercised,and teachers and students have higher satisfaction with the blended teaching mode.
