This goal of this research was to determine whether subjects completing a simplified version of a TEC lesson would differ in achievement or attitude from comparable subjects who completed a more complex version of the same lesson. Both lessons were in the conventional audiovisual format used for most TEC lessons. The audio part of the two versions was identical but the visuals on the revised filmstrip were simplified by such changes as removing background, removing uniform details from soliders, and sketching equipment rather than drawing it to scale. Eighty soldiers with the appropriate MOS were randomly assigned to simple and complex treatments. None of the differences between the two treatment groups was statistically significant. Only one item yielded a significant result, which favored subjects who were in the simple lesson treatment. Although detailed cost comparisons cannot be made, the simple lesson resulted in a saving on art work of about 40 with no loss in either achievement or attitude. It is recommended that simple art be used to the greatest degree possible in future TEC lessons.
