In order to improve the teaching quality and effect of the integrated experiment course of microcontroller application, this paper discusses the teaching methods and modes of this course. Firstly, it analyses the problems existing in the integrated experiment course of microcontroller application at the present stage. Then, it actively explores effective teaching methods according to the needs of industry and students’own development. Method, optimize teaching resources, thermostatic element put forward the reform of teaching methods, fully mobilize students’enthusiasm and autonomy in learning, and cultivate students’ practical ability and innovative consciousness. Microcontrollers in the field of automatic control were born in the 1970s. After more than 40 years of development, their cost is getting lower and lower, their performance is becoming stronger and stronger, and their application is becoming more and more extensive. They are applied in various fields, including industrial control and automation, motor control, bar code reading, consumer electronics, building safety and access control, etc. With its excellent performance and wide application range, microcontroller has become a professional skill that students of science and engineering related majors must master skillfully. Microcontroller Application Comprehensive Experiment is one of the centralized practical courses of automation specialty. In the early stage, the students majoring in automation have learned the theory and knowledge of automatic control theory, single chip computer, power electronics technology and so on. They have basically mastered the principles of microcontrollers and various electronic components. In this course, students will learn how to apply the theoretical knowledge they have learned to design micro-control circuits. This course is very practical, requiring students to combine theory with practice organically and truly master and apply what they have learned. The second part of this paper will introduce the current situation of the integrated experimental teaching of microcontroller application. The third part will put forward the reform methods of this course, and the fourth part will summarize. With the vigorous development of electronic technology, new components emerge in endlessly, and micro-control circuits become more and more complex.
The design of circuits can no longer be completed by hand alone. Computer-aided design of electronic circuits has become an inevitable trend. More and more designers use fast and efficient design software to assist electricity. The design of circuit schematic diagram and printed circuit board diagram can easily modify the design circuit and carry out simulation analysis to obtain the best design effect. This experimental course takes Altium Designer software as a tool and combines basic theoretical knowledge to carry out practical teaching of drawing, debugging and designing microcontroller circuits. This software combines the technology of schematic design, circuit simulation, PCB drawing and editing, automatic routing of topological logic, signal integrity analysis and design output. The designer can easily design the circuit. The skilled use of this software can improve the engineering practice ability of undergraduates and enhance their employment advantages. At present, this course takes micro-control circuit as the object of teaching, so that students can master Altium Designer design software skillfully, design micro-control circuit, and improve students’practical ability. However, at present, the experimental content of this course mainly focuses on the basic operation of software, and its focus is to enable students to master software design skills skillfully. The existing experimental projects are mainly basic validation and comprehensive design experiments, and there is no research on innovative experiments.
In terms of teaching methods, it is the way that teachers teach software operation and students follow suit. After the course, although students can draw the given circuit independently and design the PCB board, they do not have the ability to design the circuit independently according to the task requirements. Therefore, it is very necessary to carry out practical teaching reform, change experimental projects and teaching methods, increase the proportion of designing innovative experimental projects, so that students can design small micro-control circuits independently, so that students can really learn to apply, and can be used in future scientific research design or solve practical engineering problems. The purpose of this teaching reform is to improve the teaching quality of practical courses, improve the comprehensiveness and innovation of this course, and enhance students’practical ability. Microcontrollers are developed on the basis of automatic control technology, electronic technology, computer technology and so on.
Today, with the rapid development of science and technology, microcontrollers are constantly bringing forth new ideas, running faster and faster, and their functions are becoming more and more powerful. The experiment content should be based on new products and knowledge, and the experiment items should be able to stimulate students to think independently, search for information, design and test. Therefore, before teaching, relevant materials should be searched in many ways, and reasonable experimental instructions should be formulated while ensuring the frontier and advancement of experimental contents. A few basic experimental items should be included in the experimental items, so that students can master the methods and skills of using the software skillfully. Most of the content should be comprehensive, design and innovative projects, so as to cultivate students’ability of independent thinking and innovation, and prepare for future engineering practice, competition, graduation design and so on. In the past, teacher guidance was the main teaching method. Teachers will step by step explain the operation mode of the software, the placement and design principle of components in the circuit, the production of PCB board, etc. This teaching method makes the focus of the experimental course shift. Students mainly learn the operation of software, not the application and design method of microcontroller, which can not achieve the teaching effect of this course. Therefore, on the basis of the readjustment of the experimental items, we should improve the teaching methods and carry out guiding and case-based teaching. In the basic experiment part, teachers can explain it step by step so that students can master the operation of the software as soon as possible.
In completing comprehensive, design and innovative experimental projects, students should be the main body. In the process of teaching, teachers can use a variety of teaching methods to stimulate students’interest and potential, guide students to think about experimental projects, find out the key problems, and complete experimental projects independently. At the same time, the completion of each experimental project should have a set of systematic processes, with “project analysis – hardware selection – hardware circuit design and Implementation – Project debugging and verification” organizing teaching. Students design a reasonable micro-control circuit with 3-5 people as a group. In this process, students analyze problems, consult data, build and debug hardware circuits.
Through this experiment, students can use what they have learned, analyze and complete experimental projects, and cultivate the ability of active, active learning and innovation. In the past, the way of examination was to adopt the methods of experiment effect, experiment report and usual performance, which was not conducive to the assessment of students’ability. Therefore, it is necessary to optimize the assessment methods, and on the basis of examining the experimental results of student groups, to focus on examining the students’ability to find and solve problems in the experimental process, so as to avoid the phenomenon of individual students doing nothing and enjoying their achievements after forming a team. In order to encourage students to do more, practice more and think more. The application of microcontroller is the ability that students of automation major should master. The study of this course is conducive to students participating in intelligent car competition, electronic competition and other competitions.
It is also conducive to students’follow-up production practice and graduation design. It can also lay the foundation for students to engage in related work in the future. The purpose of this paper is to improve the teaching content and method of the integrated experiment course of microcontroller application, so as to improve the teaching effect of the course and achieve the teaching objectives.
