INTRODUCTION

National medium-and Long-Term plain for Education Reform Development (2010-2020) pointed out wholly enforcement the undergraduate teaching quality and teaching reform project, efforts to promote quality education, promotion the communication with each subject, encourage students to participate in research, strengthen the practice teaching, improve the quality of personnel training. In order to strengthen the students’ comprehensive ability, meeting the requirements for quality education, tendency of higher education developing, common basis elective general courses are subjected to the value more and more in the position and role of education in universities. However, it is limited by conditions, there is relative few experiment courses in this kind of elective courses. Wang Daheng, the father of China optics summarized the field of optic-electricity: Optics is both old and new, but the future is rosy. It can be seen, the optic-electric experiment has an irreplaceable role in training students’ scientific inquiry ability. Science and technology education should combine with the actual social development, optic-electric specialized courses not only offer in the professional major, but also should be offered elective general courses in other majors, to popularize the optic-electric quality-oriented education. The optic-electric problems in daily life can be answered directly in the traditional type of optic-electric science and engineering courses, making the students whose majors are non optic-electric science and engineering can not answer the problems related to the optic-electric in daily life, not to mention to engage in simple practical optical design skills. This obviously can not adapt the requirement of high education to comprehensive cultivation of talents in science and engineering. In this case, offering elective general courses such as modern optical experiments, photoelectric design innovation experiments courses, etc for the non optic-electric students has great significance.

SELECTION OF EXPERIMENT CONTAINS

It is determined the courses include two parts of teaching contains according the teaching purpose, combining the characteristics of courses, considering the schedules. The two parts are: the first is to introduce the basic theory of optics and optic-electric information and optic-electric devices, devices and basic experiment technology, with improving the students’ abilities to optics and optic-electric information theory and design, at the same time, providing the basis for the national college students optic-electric design competition. The second is to apply five great dozens of experimental projects such as optics generation, transmission, display, processing and design. Paying attention to develop the students’ abilities of independent design ability and innovation thinking. The excellent students are recommended to participate the national college students optic-electric design competition further10.

It will be introduced the common used instruments and devices, the basic experimental technology, light generation, light transmission, display, processing and optic-electric design theory in the theory courses. It will be done natural light, polarized light, laser and characteristic of visible light experiment in the experimental courses of light generation. It will be done optical communication, laser optical transmission, optical fiber communication, spatial light, and special transmission mode of light experiment in the experimental courses of light transmission. It will be down CCD display, optical flat-panel display, spatial light display, and special display of light experiment in the experimental courses of light display. It will be down electric-optic and acousto-optic modulation, optical holography processing, liquid crystal light value processing, and AFM micro-nano processing experiment in the experimental courses of optical processing. It will be down light generation, transmission, display, processing, design of optic-electric integrated innovation experiment in the experiment courses of optical design. At the same time, on the completion of demonstration and verification, on the basis of comprehensive, designing experiment, the students complete an optic-electric design innovation experiment in teamwork, and use the result to reply in support.

5.

REFORM THE METHOD OF INSPECTION

At present, the appraisal method of most of the experimental courses is to submitted a report as the main basis. If the lab report is finished well, the result is excellent or good, on the other hand, the result is qualified or unqualified. It will ignore the students’ performance in class and after class, especially ignore the students’ innovation thinking11. The students’ achievement can’t fully reflect the students grasp of the basic operation skills and proficiency, and whether has the preliminary design of experiment ability, analysis ability to the success or failure of the experiment, etc. To some extent, this is unfair and unreasonable, and damps down some of the students’ learning initiative and enthusiasm, it is harmful for quality education. To make the experimental courses play a more important role in quality education, in the reform of teaching methods, teaching mode should be also reformed at the same time, and the assessment of experimental courses should also be reformed to a certain extent, for the cultivation of high-quality talents.

For fair, just, reasonable and innovation of experimental assessment, it is necessary to take the oral examination, written examination, operation, reply support method to assess the students in addition to the manifestation to the students and their experimental report submitted for review. It is determined of the appraisal method according to the appraisal content, experimental conditions and the students’ specific circumstances12. To make assessment of the courses reflects on the students’ self-study ability, hands-on ability, observation ability, analytical ability, the unity cooperation ability, written expression ability, independent innovation ability and the comprehensive evaluation of scientific experiment quality.
