Based on the application of SCM principles Talent Education Reform

Paper Keywords: SCM principles multimedia teaching Keil C51 standard C language
Abstract: Principles of course for single chip electronics, telecommunications, computer and automatic control of professional students is an important professional basic courses, but most of the long-standing traditional teaching mode, a certain lack of reform and innovation, resulting in SCM Principles of teaching content and methods have become obsolete. In view of this situation. we have introduced multi-media teaching and the combination of traditional teaching mode, assembly language into the standard C language teaching, student Research study and the project in Keil C51 and other aspects to be exploratory reform the way through the survey found that most of the students teaching the principle of SCM is recognized.

SCM theory course is the electronic Information Science and Technology, Mechanical Engineering and Automation required course, but students usually attend classes for many years performance and examination results, and to work from the student feedback on the issue of view, our school SCM Principle Course there were some shortcomings. such as teaching is too old, assembly language is too rigid teaching methods, practical methods not keep up with today's job requirements. In response to the provincial model of applied Schools Undergraduate School school requirements, improve my school's educational quality and level, in 2008, we are practical, strong professional and technical courses SCM principles of teaching are explored of reform.

Teaching Problems 1
Over the years, our SCM principles are based on assembly language teaching mainly students from each examination results, students master the knowledge of assembly language part of the relatively poor. For this to develop microcontroller design application ability of students One of the main teaching objectives of the course, the programming language to master well, students master the principles of SCM can imagine. The reason is mainly low-level assembly language is the language of the machine instructions Jiandan only symbolic, register complicated operations using relatively high-level language, and requires students to have some basic knowledge of hardware is obviously difficult for students to fully grasp in a short time.

Most universities are using the first theoretical basis for the teaching process the application after the model, that single chip hardware architecture, instruction set, assembly language, design, external system expansion, interface Technology and application system design, although this approach clear thinking, but there are was too mechanical defects, the lack of vivid, visual and other auxiliary teaching physical means, this will make students feel that learning SCM boring, there is no practical significance, lack of interest, a serious impact on teaching. practice of a single form of teaching and inadequate attention. Most of the current practice of teaching to me as the experimental platform for microcontroller experiments, and are mostly offered by confirmatory experiments. observation is not difficult to find students doing experiments are mostly experimental guide books with Information on the procedures have been written, There are hardly any students to analyze the program flow, let alone read those to study the code. In addition, the experimental hardware used in the circuit, only by experimental instructions required to do a simple experiment box connection, no the whole concept of the electrical schematic diagram, together with the limited experimental conditions, not every student can get the teacher's guidance. lead to students over the pursuit of results, while ignoring the hardware design, software debugging process.

In addition, our microcontroller teaching are based on 8031 ​​or MCS-51 as an example to carry out, largely unchanged over the years, the actual MCU in the market has developed many varieties, even if the microcontroller 51 is also very rich. Such as : There are built-in watchdog, there are built-in PWM, there are built-in SPI and built-in A / D, / D / A and so on. But very few students are aware of.

2 classroom teaching Reform
2.1 multimedia teaching and the combination of traditional teaching mode
Tertiary education reform with the deep and multi-media teaching will be more extensively applied in various areas of education and teaching. Traditional teaching method is based on classroom teaching, the teacher-centered teaching, and this practice of SCM principles courses stronger classroom teaching, it is clear the traditional teaching methods can not fully mobilize the enthusiasm of students, and multimedia teaching method is through computer Technology, network Technology, multimedia Technology and modern teaching methods of teaching and learning activities, set text, images, sounds, video images, animation, and other Information in one, teaching is more image, intuitive and vivid. for example, by using the extensive network of resources, the students can understand the current new book news on the microcontroller, new technologies, new Information and related content areas, understanding SCM application and development of the status quo. while the final chapter in each representative on the network and application issues moved to the classroom, organize a discussion and analysis together, can make classroom learning the basic knowledge and practical application of contact together. This can guide the students learn to collect and digest the relevant resources on the network, the Institute provides access to microcontroller chip manufacturers technical Information, software and hardware design for the future lay the foundation themselves.

2.2 in assembly language into the standard C language teaching
View of the assembly language is not easy to master, teachers in the teaching of principles of complete microcontroller hardware, instruction set and assembly language programming section, the microcontroller can introduce the teaching content of the standard C language. Its contents include the basic syntax of C, C data structures , C and C, the storage structure of the knowledge of process control points, and explain the process for comparison with the assembly language, understanding both the port and the interruption in the different definitions, the students understand the hardware architecture based on single chip, understanding of C data structures, storage structures and microcontroller hardware correspondence between each other. In addition, in the learning process, to make students realize the C language relative advantages of assembly language: such as the C language, readability, maintainability good, easy to maintain and debug, and code reuse and transplantation.

That the use of assembly language and C language for the control of the teaching mode, students can quickly grasp the SCM in the near future the application of programming principles, will no doubt the late great benefit for learning.

2.3 introduces the most commonly used microcontroller development tools Keil C51
With the development of integrated circuit microcontroller continuously improve performance, applications become increasingly wide, single chip debugging tools is constantly being improved compiler. The most commonly used development tools, Keil C51 is produced by the United States KeilSoftware Company C-51 compatible microcontroller software development system, Keil C51-rich software library functions and powerful integrated development and debug tools, the whole Windows interface, while with the Windows version of the software update system continue to improve, another important point, just look at the compiled assembly code generated to Keil C51 can understand the efficiency of the object code generated is very high, the majority of the assembly code generated statement is very compact, easy to understand. Figure 1 for the operating system interface of the software, the window title bar followed by the menu bar below the menu bar is a tool bar, tool bar to the left of the following is the project manager window, the window only to see the project documentation, you can view real-time program execution registers the value of J in the management of the right window is the editing window, beneath which is a command and a variety of output window at the window, these windows can be the View menu (View) the following command to open or close.



Zai introduced on the basis of the standard C language to college students have toward society, able to quickly adapt to factories and enterprises related to product development of SCM, we guide the students to grasp this development platform to use, so that the future lay in a good the work of the foundation.

Practical Teaching 3
3.1 changes in the traditional experimental models
We try to change the traditional course of the experiment to verify the nature-based experimental model, the instructor provides only the direction of the experiment, the students according to the experimental goals, and advance preparation, to the library or online access to their Information, experimental design, preparation of relevant experimental procedures. In the experiment, problems with team members discuss solutions, and finally get results. Students should experiment according to their own lab report writing, including the problems encountered in the students experiment and to propose solutions. At the same time teachers can also organize exchanges between students of each group to analyze and report results and discuss the call, thereby enhancing the students ability to Research capacity and scientific experiments. reposted elsewhere in the Research Papers Download http://www.hi138.com 3. 2 full use of extracurricular time
SCM is also a principle of teaching practice of extra-curricular courses teaching a very important part of it is not merely a supplement to experimental teaching. In fact, college students through the organization of interest groups can participate in the Research of teachers in various ways such as extra-curricular learning, such as Youth League at my school and science and technology Research organizations, students reported learning project, in large part inspired the innovative spirit of students and strengthen their practice, thereby enhancing their ability to solve practical problems independently. In addition, the microcontroller program classroom teachers are properly guide the students to be extra-curricular learning, for Research of interest to them to provide references to guide students to understand the latest developments, grasp the research, and discussion among students, encourage students out of school to attend a variety of embedded into Equation system of lectures, participate in a variety of internal and external organizations related to the contest with the microcontroller, the students broaden horizons, increase their abilities, and gradually develop their own research capacity and innovation.


4 Conclusion
In MCU and practical aspects of teaching in the introduction of new content and teaching methods, whether to raise the students in this course interest and enthusiasm in learning it, we designed a single chip as shown in Table 1 Principles of curriculum evaluation questionnaire to test the students on the curriculum reform, teaching acceptance, respectively 05 and 06 a total of 280 students conducted a survey of statistical results are 05 students in the Top 122 scores average score 88.36 points 06 158 students are given the average score is 90.02 points. can be seen by the students after the reform the evaluation of SCM principles of teaching, the course is not so difficult to learn, as long as we use the rational teaching methods, through various means and improve student interest in learning to be able to achieve good teaching results.
