This document summarizes two studies on the effectiveness of interactive videodisc instruction (IVDI) and distance learning technologies: 1. A 1990 study by Fletcher found that IVDI increased achievement over conventional instruction in military training by 65% and in higher education by 75%. IVDI was also found to be more cost effective than conventional instruction. 2. A 1990 study by Hobbs in North Dakota found no difference in achievement between distance learning technologies (interactive TV, audiographic tele-learning, instruction by satellite) and traditional foreign language instruction. The conclusion is that the technology used is less important than how, when, and for whom the education is delivered, as both traditional and distance learning can be effective
