Description :From the images of domestic animals photographed with digital cameras and the images of fertilization of gametes and early development of zygotes in various mammals taken by a CCD color camera connected to an inverted microscope and a time-lapse video cassette recorder, dynamic visual aids have been created and developed. These dynamic visual aids that have been independently created were utilized in actual classes and their educational effectiveness was clarified through questionnaire surveys. With respect to the query upon whether characteristics were comprehended regarding the mammalian germ cells (sperm, eggs and embryos) as resources and the biotechnological new techniques in animal production, 66 or 80% of the students replied in the affirmative far exceeding the number of students who replied in the negative. Furthermore regarding the query as to whether seeing the slides of eggs and embryos in various mammals and their video images was instrumental in their respective understanding of them, over 84% of the students answered in the positive. From the above, the use of independently developed slides and video images as teaching materials was judged as being undoubtedly effective in the comprehension of the content of lectures. From the results of questionnaire survey, it was concluded that the educational effectiveness of courses which positively employed such visual aids was undoubtedly large.
