Characteristics of the Most Effective Tools


Effective tools of public awareness, mass communication techniques and teaching and learning approaches, include the use of simple, low-cost visual aids. Traditional ways of communication based on cultural heritage should be taken into account. A brief description of mass communication techniques, specifying their advantages and disadvantages, is presented in IETC's Technical Publication Series number 11 (chapter 4, p.131). Simple materials and approaches are often more effective because they use readily available resources and can take into account local knowledge and existing communication channels. (see Marionnettes and puppet show in Mali, p173, IETC Technical Publication Series number 11).
