Title: A system for selecting media for school library collections based on the matching of task, stimulus, and learner variables
Abstract: Tnis study was undertaken for the purpose of designing and testing an instrument which can be utilized in identifying media t~at are wost appropriate for tran5mitt~ing knowledge in a representational form required by a particular l~rner to master a particular task. The instrument identified as the D-model was designed using a systems approash which incorporated three components: task, stimulous., and learner. The hierarctical arrangement of elements within each component permits an analysis of the inter- relationship of the task and learner variables to enable the identification of stimulus selection possibilities. The stimulus selection depepds on the particular intersection between the task variable and the learner variable on a matrix. The matrix incorporates the elements for each component arranged on a continuum from that which provides for direct, concrete experience to that which provides for indirect, abstract experiences. The procedure involved in utilizing the D-Modei requires the examination of objectives identified in the instructional program to ascertain the specific task to be mastered. The characteristics of the learner who uses the stimuli to acquire knowledge of the task to be mastered are then analyzed. Once the specific task has been identified and plotted on. the task axis and the characteristics of the learner identified and plotted on the learner axis, the point of intersection of these two lines on the stimulus axis is used to identify the stimulus that is most appropriate for transmitting the information. Once these decisions have been made, specific media are selected from those identified for that partic~ lar stimulus category.
Three experiments were designed to test the effectiveness of the stimulus choices identified by the D-Model. Experiment I was designed to test hypothesis: There will be no significant difference between the stimulus choices identified by using the D-model and those identified by "experts" in the field. The results. reveal that the stimulus choices identified by using the Model'are consistent with those identified by "experts"; and that although some differences did occur, these differences did not constitute a rejection of hypothesis 1. Experiment II was designed to test hypothesis 2: There will be no significant difference between the stimulus choices identified by using the D-Model and those identfied in curriculum guides and textbooks.
The results reveal that the stimUlUS choices identified by using the D-Model are significantly different than those identified incurriculum guides and textbooks. To ascertain if these diffrences were due to a lack of available media in selection aids, a second analysis was undertaken. The results reveal that the lack of their inclusion in the curriculum guides and textes cannot be attributed to the nonavailability of media in the selection aids since media were available in all stimulus categories. Thus it is apparent that hypothesis 2 must be rejected. Experiment III was designed to test hypothesis 3: There will be no significant difference between the stimulus choices identified by novice librarians using the D-Model and novice librarians using selection aids. The a participating in this experiment were students enrolled in an undergraduate library science course at Edinboro State College. A two-way analySiS of variance performed on these data revealed a significant difference between the results of the two groups in the direction of greater gains for the group us ing the D-r<1odel. Thus it is apparent that hypothesis 3 must be rejected. The data from this study raise SUbstantial doubt as to the effectiveness of relying on stimulus choices identified in curriculum, guides and textbooks as a means for selecting media for a school library collection that will support the instructional program. Furthermore, there is some doubt as to whether this situation can be improved by selecting media by examining those stimuli identified in selection aids. However, there is evidence to support the use of an instrument designed by using a systems approach such as the D-Model for identifying stimulus choices that will support the instructional program.
