EDUCATIONAL-ASPECTS OF SONOCHEMISTRY - THE ROLE OF SONOCHEMISTRY AT HIGH-SCHOOL LEVEL

The applications of sonochemistry have attracted a great deal of atten tion. However, conventional chemistry textbooks used in universities a nd high schools cover traditional chemistry plus thermo-, photo- and e lectrochemistry The effect of sound on chemical systems has completely been ignored. Although the mechanisms of many sonochemical reactions remain unresolved, the rapid expansion of knowledge in sonochemistry h as already justified its inclusion in present chemistry curricula. Mor eover, the interesting and unusual phenomena encountered under sonicat ion conditions can be used for motivation purposes. Furthermore, explo ring and equipping students with a new tool for investigating chemistr y is also important based on educational principles. This paper examin es some chemical systems (in a high school chemistry syllabus) which a re affected by sound energy. It is hoped that these sonochemical appli cations will facilitate the learning of chemistry in terms of cognitiv e, psychomotor and affective domains.
