Evaluation of an integrated multi-media learning system.

Two teaching methods were compared: (1) the traditional way with textbooks, practical guidance, personal demonstration, and (2) an integrated multimedia system with text programme, slide-sound-show accompanying the experiment, and lecturer. Two samples of thirty-one students each were classified in twin groups by means of psychological tests. Both groups worked with the identical pretest/post-test and different training procedures. The integrated multi-media system produced highly significant more gain in the theoretical sphere, greater personal confidence, and lower experimental error. Furthermore positive attitude of the students towards the experiment was demonstrated. The improved performance was statistically proved by t-test and covariance analysis.
