Abstract
This study was carried out to find out the level of understanding of selected chemistry concepts
by senior secondary school students in Osun state, Nigeria. Two hundred and ninety one senior
secondary school III (SSIII) students from six purposively selected secondary schools were used
for the study. A test item termed test of concept understanding in chemistry (TCUC) was used. It
was found out that the students’ level of understanding of chemistry concepts was low and that
students performed better in theoretically related concepts than in practically related concepts.
Students also found it difficult to understand the following concepts: the mole concept,
electrolysis, chemical formulae, equations and balancing of chemical equations, electronic
configuration, preparation of salts, calculations in volumetric analysis, physical and chemical
changes, and properties and identification of gases. Students however found it easy to understand
acids & bases, and simple separation techniques.
