Results: 97 per cent teachers responded that activity based method was better than lecture for retention and application of activity. Activities illustrate the practical application of theories and, most important, the relation between theories and practical results. 85 per cent teachers were of the opinion that the use of activities will enhance students__ampersandsignrsquo; ability to recognize multiple perspectives.
