Evaluating the Electronic Blackboard: Technical Paper #1.
Stahl, William A.; Johnson, Brian
This study of the effectiveness of electronic blackboards in three introductory sociology classes at the University of Regina tested the hypothesis that this microcomputer-based presentational technology would have a negative impact on faculty productivity due to the increased amount of preparation time, and a positive impact on the quality of learning. Computer-prepared illustrated lectures were presented to two test classes, while a control class received the same material without the illustrations. Evaluation questionnaires using a five-point scale were administered prior to and after the experiment to all three classes. In addition, an in-class observer monitored all three classes, and all three were videotaped for review by a faculty panel. Follow-up interviews were conducted in both test classes. It was found that the electronic blackboard method was not successful because: (1) it took faculty five times longer to prepare an illustrated lecture than a normal one; (2) the electronic presentation interfered with normal patterns of classroom interaction; (3) students were dissatisfied with the electronic blackboard; (4) the electronic blackboard forced students to concentrate on two different sources of information simultaneously, resulting in a negation of any benefits gained by superior organization and visual imagery; and (5) rural and low income students may have been negatively affected. It is concluded that, given the current state of the technology, the electronic blackboard is not effective under the conditions tested. Copies of the study consent form and the pre-experiment, control group, and test group questionnaires are appended. (5 references) (DB)
