A revolution is taking place in education today at all levels from kindergarten through college, in virtually all subject matter areas. This revolution is due, in part, to research in learning theory and technological advances. Changes in attitudes have led to the concept of "accountability"--that educators must perform and produce educational programs that are meaningful and interesting as well as informative. The fact that private industry has had satisfactory results in the academic marketplace has also provided impetus for the current educational revolution which has resulted in several innovations.A general education biology course, Man and the Life Sciences, has been taught with an audiotutorial component at Ball State University since 1965. Quarterly evaluations by the students provided the staff with evidence that three of the units should be redesigned 1) to have more appeal to the students; 2) to meet their expectancy of relevance; and 3) to have a higher level of academic quality.The problem for the present research investigation was twofold: 1) to design three audiotutorial units for a college general education biology course titled Aggression, Territoriality and Survival; Time, Adaptation and Change; and Man, Communication and Behavior, with innovative approaches and 2) to evaluate the effectiveness of the newly developed materials.In designing these three units, specific goals of the research undertaking were 1) to integrate the three units in such a way that concepts of organismal biology, evolution and behavior are pervasive throughout all three units; 2) to develop a list of performance objectives for each of the three units; 3) to determine learning strategies which will help the students achieve each of these objectives; and 4) to determine learning strategies which will help make these objectives interesting and relevant to the students.In order to meet these criteria, the principles of systems management were employed bys 1) specifying goals, 2) specifying desired outcomes for students, 3) planning instruction, 4) evaluating student achievement, and 5) revising instructional procedure in light of experience. In planning the instruction, the method used to facilitate the accomplishment of the desired outcomes was the audiotutorial approach which allowed the student to learn at his own pace. Each unit actively involved the student in sequential multimedia learning activities. A learning guide was designed for the student to use in responding to questions posed as he progressed through the audiotutorial learning activities.After development, the unit materials were first tested with a group of ten students. Feedback on the basis of achievement tests and individual interviews provided the rationale for revisions in preparation for field testing. After completion of the field testing, which involved approximately 650 students, additional revisions were made, resulting in the final version which was evaluated to determine the overall effectiveness of the learning materials.Final measurement of student accomplishment was effected by the use of pre-tests and post-tests consisting of parallel quiz items which had been validated in preliminary testing. Forty-five objectives were final tested; difficulty levels from the pre-test indicated that twenty-four of the objectives were achieved by seventy percent or more of the students. Chi square applied to the results of the remaining items indicated that seven additional objectives probably were also achieved at this same level; fourteen of the objectives were not achieved during the final evaluation. Standard item analysis was used to assist in determining why these objectives were not accomplished; this information can be used in making future revisions.Student opinions were solicited in the form of a student unit evaluation. At least forty percent of the students rated each unit's interest level as high and fifty percent rated each as average; thus, the units accomplished what was expected.A program of instruction should evolve with new ideas and innovations with an effort toward continual improvement. Data collected from this research investigation can be used to pinpoint specific areas where additional research would be beneficial.
