In order to solve the problem that students are difficult to learn and tired of learning, the author combines the teaching experience accumulated over many years to propose the teaching method of "machine tool teaching platform". I. Limitations of the Traditional Teaching Method The traditional teaching method is based on the sequence of textbooks and is explained step by chapter. This method is divided into individual parts in chapters. Teachers usually explain in this order. They use more classes and are less coherent. Students often learn the latter. The content has long been forgotten. Many students report that they have not learned anything during the semester. The author believes that the main reason for this phenomenon is that the learning content is too scattered, lack of comprehensive analysis and induction training, resulting in students' understanding, application ability is not high, and knowledge and memory are not strong. Second, the teaching method of the machine tool teaching platform The teaching method of the machine tool teaching platform is based on the machine tool, the machine tool is regarded as an organic whole, and the learning of the "Mechanical Foundation" course is built on the carrier of the machine tool. Through the understanding of the structure, movement and transmission of the machine tool, the learning content of "Mechanical Foundation" is permeated in the process of machine tool learning, focusing on the whole machine tool. The advantage of this treatment is that students feel that the knowledge points are not scattered when they study this course. By comparing the position, function, characteristics and problems of various transmissions in the machine tool, especially in combination with the movement of the machine tool, it is possible to analyze each The root cause of the phenomenon. Teaching practice proves that through such learning, students' ability to understand knowledge has improved, remember to be firm, and more importantly, the ability to analyze and solve problems has improved, and has also improved the enthusiasm and interest of learning. Third, the implementation method of the teaching method of the machine tool teaching platform In view of the actual situation of the current vocational and technical schools, the machine tool teaching platform consists of two parts: the physical machine tool and the multimedia courseware. 1. The physical machine tool is mainly used in the early and final stages of teaching. The teacher can use the machine tool of the school internship factory to make the students understand the noise, vibration and other phenomena in the machine tool mechanism, machine tool movement and machine tool transmission. Conditions can be disassembled and machined to understand the internal conditions of the machine. The purpose of this is to enhance students' perceptual knowledge, enhance students' interest in learning, and more importantly, let students know what to learn in this course. Teachers can preliminarily explain the names, functions, and transmissions of various components (parts) through preliminary visits, and appropriately raise some questions for students to think about; when they are late in learning, they can work on a certain part to deal with phenomena and problems during the period. Let students analyze and solve themselves, discuss whether there are better ways to improve, etc.; in the medium term, you can use some live video discs, such as "Treadmill Operation Skills" and "Milling Operation Skills" to let students know where their knowledge is used. 2. Multimedia courseware (or wall chart) This is the main means of learning "Mechanical Foundation" in the classroom. Often a machine tool does not contain everything to be learned in the Mechanical Foundation, so two or three machine tools are required to meet the teaching needs. At present, multimedia courseware can be used to learn machine structure drawings and transmission schematics. The most commonly used machine tool is the CA6140 lathe. The teaching is based on the machine tool transmission sequence, and each part is analyzed step by step. During the analysis process, the students can see the position of the transmission mechanism in the machine tool. The teacher explains the corresponding contents of the textbook and has targeted Each part of the transmission mechanism is analyzed, such as the structure, characteristics, transmission ratio, transmission characteristics, work situation and the problems that are easy to occur in the transmission process. It has a focused and targeted explanation, which inspires students' thinking and mobilizes students to participate. Enthusiasm. After many years of practice, the author believes that this method is very effective. Students feel that classroom learning is not boring, key knowledge can be grasped, learning ideas are clear, review is convenient, and more importantly, students can summarize a problem in their own language. Each type of machine tool is a collection of mechanical transmissions. After the transmission is completed, the same method is used for the other type of transmission. When we complete the analysis of the whole machine, the contents of "Mechanical Foundation" are almost finished. . In this process, students learn both the knowledge required in the outline and the methods of analyzing the problem. During the course of the course, students are required to compare various transmissions and find the advantages and disadvantages between them. In the final stage of teaching, students are allowed to design a combined transmission system to organize students to debate and find out for students' diverse designs. Out of the advantages and disadvantages and problems. IV. Analysis of the effect of the teaching method of the machine tool teaching platform The teaching method of the machine tool teaching platform is a total teaching method, that is, firstly, the overall situation of the machine tool is recognized, and then each part is analyzed one by one, and finally according to the knowledge of each part. Comprehensive induction, complete the teaching requirements of the "Mechanical Foundation" course. Since all vocational and technical schools can provide machine tools and multimedia courseware (or wall charts) for the machine tool teaching platform, the machine tool teaching platform is feasible in teaching.
