Abstract
The present paper deals with the introduction and its effects on student practices of Audio-Visual Aids as a teaching tool in the organic laboratory courses at Gunma National College of Technology. Students occasionally misunderstand ways of handling chemicals and apparatuses used, which may lead to serious laboratory accidents. We, therefore, have considered necessity of introduction of Audio-Visual Aids on how to perform the experiments effectively and safely. We have carried out lectures using the Audio-Visual Aids containing methods of handling apparatuses and chemicals. Based on our observations and analyses of the questionnaire, it is reasonable to consider that students have gained better understanding of the contents of experiments and their skills needed for safer and more effective experiments have been improved.
