Teaching research university is given priority to undergraduate course education, discipline construction, scientific research as the auxiliary, strengthen the ability of engineering practice, training institute and enterprise oriented a line of specialized technical personnel. To cooperate the teaching goal of colleges and universities, colleges and universities education workers for a variety of teaching mode of exploration: the research of professor yi-lin song of heilongjiang university “Research-based teaching model exploration based on the applied talents training”^[1]; Dr Jian-yong zuo of Tongji university studied: “Practical teaching mode and case analysis for engineering” ^[2] and so on^[3,4]; In the undergraduate teaching of institutions of higher learning, the immediate problem is to explore the teaching mode of cultivate and strengthen the engineering practice ability, the effective combination of theoretical knowledge and practical ability. In this paper, A set of teaching mode suitable for Information classes, aiming at training students’ engineering practical ability will be explored in Optoelectronic Information Science and Engineering courses of undergraduate teaching as an example.

The current status and the existing problems in Information classes of Optoelectronic Information Science and Engineering

Optoelectronic information science and engineering is a new professional to adapt to photoelectric development combine Optoelectronic technology, Image analysis technology, Communication technology, Information fusion technology, Computer science, The control technology into an organic whole. The training goal is the engineering senior specialized talents have the basic theory, basic knowledge and basic skills of Optoelectronic information science and engineering, be able to engage in technology research and development, engineering design and production management in the field of Applied optics, Optoelectronics and related information science, especially in photoelectric information industry fields. Information classes of Optoelectronic Information Science and Engineering come from Electronic Information Engineering, The courses of Electronic Information Engineering is as Table 1. Professional Settings have a set of curriculum of professional foundation courses, professional courses and engineering training process in order to achieve the training objectives of this major. Photoelectric information class curriculum isn’t the major research direction of learning of optoelectronic information science and engineering, the total class curriculum is too less, the curriculum as Table 2. It basically set up professional foundation courses and part of professional courses, and it has little practice teaching link. The teaching mode is the traditional teaching mode: Mainly classroom teaching. It mainly teaches the basic content of communication principle and the relevant theoretical knowledge of communication technology. The problems must be solved are as follows: What kind of teaching model is adopted and how to put them into these courses in the teaching within the limited class hour to let the students effectively master the photoelectric signal from the acquisition, loading, transport, accepting, restore the entire process to achieve the teaching effect of combining theoretical study with the engineering practice.

The construction idea of the training platform

For undergraduate teaching of information class curriculum of Optoelectronic Information Science and Engineering, The teaching mode aiming at training students’ engineering practical ability. The construction idea is to cultivating the practical ability of students as the theme, to realizing the optical signal collection, transmission and receive training platform as the foundation, to training students to start with the information transmission system design of life. According to the requirements of the actual system need technology to study related theory knowledge in order to meet the actual needs of information transmission system design. Do theoretical study to serve the practice requirements to stimulate students’ interest in learning. Let the students to design their own information transmission system design and simulation test using the MATLAB software simulation training platform of information system after information system design is completed. The aim is to train the students’ computer programming ability, communication system simulation implementation capability and the simulation of different signal test ability. The hardware platform achieving information transmission system is made at the experimental practice link according to the result of software simulation to train students’ information circuit implementation and hands-on ability. To achieve the target of raining students’ engineering practical ability through the whole process training of the information transmission system design, simulation, experimental implementation.

The construction of training platform

The construction of practice training platform is on the basis of the development of the small communication system from the Voice, Image, Data Signal Acquisition, Coding, Modulation, the launch, Transmission, Accept, Demodulation, Decoding, to the final signal recovery. The overall plan diagram as shown in Table 3 mainly divided into part of classroom teaching, course design and professional experiment.

Conclusion

In the teaching mode of engineering practice as the goal, the information transmission system design and software simulation and hardware implementation process are complete by problem oriented type of classroom teaching, the computer application training of curriculum design, give priority to the hands-on practice ability of professional experiment, so as to achieve the training goal of the undergraduate education of teaching research university, to strengthen the ability of engineering practice, and to train institute and enterprise oriented a line of specialized technical personnel.
