Four experiments involving 180 undergraduate students were designed to evaluate the effectiveness of computer graphics in improving estimates for algebra word problems. The demonstration simulated points moving at different speeds, tanks filling at different rates, and mixtures of different concentrations. Variations in the simulations resulted in both successful and unsuccessful programs, as measured by how frequently students improved their estimates. Variables that influenced the success of a program included successive versus simultaneous presentation of examples, active versus passive viewing, and the similarity between examples and test questions. The quality of feedback received by students while learning by viewing, doing, or being coached is compared for these and other programs., (C) 1985 by the American Psychological Association
