| 2022 is a key year for vocational education to improve quality and reform.Since the 19 th Party Congress,in order to thoroughly implement General Secretary Xi Jinping’s important instructions on vocational education work and the spirit of the National Vocational Education Conference,the Ministry of Education has launched a number of policies to implement vocational education teaching reforms after each other,and the quality of vocational education has gradually become a concern to the society.The key to guarantee the quality of vocational education is the overall quality of secondary school students,and the good learning effect of secondary school students is one of the important ways to improve the overall quality.Mechanical Drawing is a basic course for secondary school mechanical majors,and it is an important foundation for learning other professional courses well.However,there are problems that affect students’ learning effect in the teaching process of Mechanical Drawing,such as the poor learning condition of Mechanical Drawing classroom,and most secondary students are not interested in this course,which is one of the most common problems and students will influence each other,if this status quo is not improved in time,it will adversely affect students’ growth and success.Therefore,this paper proposes a study on improving the interest of secondary school students in Mechanical Drawing based on problem-based teaching,so as to achieve the purpose of adjusting students’ class status,ensuring learning efficiency and improving teaching quality,which is in line with the requirements of educational reform and has important practical significance.Firstly,this study aims to improve the learning interest of secondary school students in Mechanical Drawing course,and conducts a survey on the current situation of secondary school students’ learning interest in Mechanical Drawing course;secondly,we find out the problems of secondary school students in the learning process,including inattentiveness in class,low learning efficiency and students’ fear of difficulties,and then analyze the reasons that lead to these problems in students’ learning Once again,four teaching sessions based on problem orientation are proposed: Session 1 "Look at the diagram to know what is going to happen",the initial understanding of the drafting content to be learned in this lesson,for the problem finding stage,students watch the teaching video after the class,learn the knowledge points,observe the problems in the drawings given by the teacher,and create a pool of problem entries;Session 2 "Learn the diagram to understand",systematically learn the drafting knowledge points taught by the teacher,for the analysis of the problem phase,this session for students to learn with problems,students listen to the teacher’s lecture on learning content,carefully take notes,write down important knowledge entries,follow the teacher while listening and practicing,create a pool of knowledge points and notes entries;session three "Practice the drawing to check the effect",independent drawing to test the learning effect,for the benchmarking problem stage,screening out the evaluation entries,independent drawing to benchmark the problem,selfcorrection and self-examination;session four "evaluation of the drawing to promote introspection",tripartite evaluation of the drawing results,reflecting on the mastered drafting knowledge,for the The evaluation is an important feedback and motivation tool for students’ learning,and the feedback on the learning results is made through the self-made evaluation entries and teacher’s evaluation,and the development of students’ learning process is evaluated through the collection of learning data records and feelings;finally,the multi-effect analysis shows that the classroom of Mechanical Drawing,which starts from the problem-oriented approach,has a positive impact on the students’ listening status,their learning status,and their learning ability.has a positive impact on students’ listening status,learning efficiency and quality,and intimidation,and has a certain effect on the enhancement of students’ learning interest,and the pool of entries created by students is gradually approaching the teacher’s standard pool of entries,and the teaching effect has been revealed.It is hoped that this teaching study will provide some experience reference for the development of the middle-level "Mechanical Drawing" course,provide reference and reference for the teaching reform to enhance students’ learning interest in the middle-level "Mechanical Drawing" course,and also lay the foundation for middle-level students to work in related positions in the future. |
