    This thesis reports on school teaching and learning problems in the area of chemical re&ctivity and on an attempt to overcome some of these problems with an in-service course for teachers. rhase 1 of this research was a study of the conceptions of aspects of reactivity, rates of reaction and chemical equilibrium held by secondary school students. The nature and origin of the conceptual di:Eficltlties, i.n the above areas were investigated. The concepts of ret,ctivity and reactivity se.rd.e s are formally introduced at a standard 8 level. These concepts form a springboard for the understanding of more formal quantitative worl< done i.n rates of reaction and chemical equilibrium at a standard 10 level. Two multiple-choice questionnaires, a reactivity qUestionnaire and a i'a'Ceand (.,quilibrium qUestionnaire, were designed to probe for the nature and ori9i.n of views held )y st
