The Education Network of Maine: A Case Study in the Benefits and Costs of Instructional Television


A statistically significant difference in average grades between broadcast and receive site students (in favor of the broadcast site students) was found in only one course. Of the remaining 17 courses for which sufficient data were available to conduct a 't' test, the differences in average grades were not statistically significant ... There were no significant differences between the responses of the students in the live network and the videotaped version of the course. Based upon these survey responses, there is no evidence that receive site students preferred the live network course over the videotape version of the same material.
