Keywords: Animal Physiology Experimental Teaching Experiment Aquatic animal physiology

3、 is aquaculture, marine fisheries science and technology, science and technology and other professional aquarium required one of the professional foundation courses. Aquatic animal physiology is a strong theoretical and experimental science, all from many of its mechanism in the experiment, emphasis

4、 on theory and practice, through teaching, not only can students understand and master the basic experimental methods and operations, and other professional skills, to build a scientific way of thinking, from the system, organ and cell biology to understand the physiological level function of channe

6、n. In order to meet the coastal city of agricultural training of personnel, training students the necessary skills and hands-on experimental ability, therefore, to pay close attention to experimental teaching, improve the quality of teaching animal physiology experiments. how to motivate students in

7、terest in learning so that they can actively take the initiative to participate in the physiological experiments, we have been thinking and efforts to solve the problem. In recent years, we have to aquaculture, marine fisheries science and technology professional aquatic animals for experimental tea

An aquatic animal physiology experiments teaching content 1.1 Experiment to determine the content of the re- T

20、f teachers, students self-prepared test The traditional experimental course, always do the experiment by the preparation of teachers, with the theory of teaching content, the arrangement of pilot projects are mostly some of the classic experiment, students at experimental guide (tutorial) steps requ

21、ired to complete step by step experimental operation, ability to Debu to the full and complete exercise, not an open mind, but also a waste of training opportunities. To this end, our group carried out experimental work to try to prepare lessons, organizational learning interest groups, students tak

22、e turns before the experiment into the laboratory, the preparations for each experiment, including experimental grouping, laboratory equipment and instrumentation installation, experimental drugs and reagent selection and preparation, holding culture and other laboratory animals. Students interested

23、 in the experimental preparation, a very active enthusiasm; experiment room order in good order, the original often between the groups resulting chaos to take supplies and medicines, what end of the experiment and so lost much improved. This is mainly because the preparatory work so that students an

24、d laboratories throughout the experiment with a comprehensive arrangement understanding, the main thing is to improve students ability to work independently, they have a sense of ownership, active efforts to complete their experiment, always want to prepare their own experiments to achieve the best

25、experimental results. 2.2 update laboratory equipment to improve student interest in learning Through the introduction of modern laboratory equipment, and further optimize the experimental teaching environment. Animal Physiology Laboratory experiments carried out in 2006, upgrading and updating the

26、facilities, the use of RM6240 experimental system for biological and functional test operations and data processing. The experiments to quickly and accurately to the experimental more objective and informative. conducive to the students on the experimental results, the graphical analysis, understand

27、ing of knowledge beneficial to stimulate the students interest in learning, improve student motivation and initiative. 3 improve the assessment system Experimental results assessment system directly affect the students in experimental class learning attitude and motivation. Norms of experimental per

28、formance appraisal system is able to fully mobilize the enthusiasm of students and cultivate their comprehensive quality and innovation. In view of this, the program abandons the past only in accordance with the experiment results calculated as the average experimental method of evaluating performan

29、ce, and constantly improve the evaluation system, including scores of students preview the report experimental course (20%), experimental operations (40%), laboratory reports (40%), according to each experiment proportion of these projects and give results. to each class queue of student achievement

30、, and finally the experimental results the students were evaluated by percentile, which accounted for 85 points or more the number of 20% of the total number of class. This comprehensive assessment program results method than the previous method used a more comprehensive, objective and impartial, ap

31、proved by the majority of students, but also encourage students to actively participate in the experiment and initiative further. 4 Conclusion Through years of practice, aquatic animal physiology experiments have achieved good results, lab look greatly changed. Mobilized from a wide range of student

32、s interested, but also can guide the students to consciously, actively participate in the experiment, a test class subject. cultivate the students the courage to explore, research and awareness, and pragmatic work attitude, consolidate and strengthen the students basic knowledge of animal physiology and experimental skills, stimulate their scientific and technological innovation in teaching by the students as teaching good effect.
