Abstract “Man is at his best when stimulated by the hope of reward, the fear of failure and the light of a star.” - Author unknown. Computers offer many varied opportunities to try something new, innovative and exciting. To be sure, using the computer has a ‘charisma' or magical charm for today's student. It is rewarding to the conscientious teacher who capitalizes on this enthusiasm builder. But, the primary objective of teaching is to cause learning so the educational value of the computer in aiding the animal science student to learn is the issue. The topic “the computer in animal science teaching” will be approached from this perspective. The computer has been used for 7 years to teach certain animal breeding principles to 1,356 students who were enrolled in Applied Animal Breeding at Iowa State University. A colleague has had over 420 students enrolled in introductory Animal Science who have used the PLATO system3 for the last 1 1/2 years. Another colleague routinely uses a least-cost model in sausage formulation. In addition the telplan system from Michigan State University has provided some on- and off-campus experience with a cattle feeding problem. The information presented herein is based upon a composite of the experiences in these areas. LITERATURE REVIEW The number of instructional simulations developing during the last decade indicates they are becoming a popular method of instruction. Zucherman (1970) reviewed 405 functional and active non-military simulations and omitted from consideration 450 more due to incomplete information. After analyzing the educational goals This content is only available as a PDF.

SUMMARY The use of computers, systems analysis, and mathematical modeling techniques in support of animal science research has been introduced. Modeling procedures were illustrated using several example models previously reported. The use of modeling techniques together with the computer not only helps integrate existing knowledge leading to greater understanding of complex systems, but is also a valuable research tool which can be used in testing hypotheses, and in estimating biological parameters which are not directly measurable. The modeling process is not an end in itself because in the final analysis, a model is only as good as the data on which it is based. Modeling complements experimentation and can lead to a more efficient choice of experiments. The modeling process itself, independent of progress made in model development, is beneficial in forcing more rigorous and quantitative thinking, destroying preconceived notions and adding greatly to one's understanding of a biological system.

INTRODUCTION Extension use of computers to perform “accounting” functions including Dairy Herd Improvement Association, (DHIA), beef cow herd performance, and farm business record analysis has been extensive, beginning in the early 1960's. At the same time, industry has made extensive use of computers in feed formulation and inventory control. These roles are assumed to be well known; this paper focuses upon the teaching tools made available by the recent introduction of time-share computing into extension education. Instead of beginning with a discussion of principles, an application of time-share computing decision-aids as part of an education program in the development of good feeding systems will be discussed. The decision-aids were developed cooperatively by an informal consortium of workers, primarily in the corn belt states, and reflect extensive use–currently 22,000 runs per year. Subsequently, based upon having obtained a perspective on a typical application, attention will be turned to other applications; to how one goes about organizing such an activity; to the interface between applied research and extension, between departments, and between universities; to the interface of computer tools with other extension teaching aids; and to integration with service activities including feed nutrient evaluation laboratories. WHAT ARE MODELS FOR? The first question a potential user of computers in extension education must ask is, “What kinds of problems are we attempting to answer?” And consequently, “What information will be needed to solve the problem(s)?” Major uses by consortium members of the feeding systems package include: (1) developing feeding systems with farmers on This content is only available as a PDF. 1978 by American Society of Animal Science
