ab: Summary: This study examines secondary school studentsâ€™ understandings
and misconceptions when working with logarithms using a specially
designed test instrument administered to 81 students in two Singapore
schools. Questions were classified by cognitive level. The data were
analysed to uncover the kinds of errors made and their possible causes.
Students appear capable of doing routine calculations but less capable
when answering questions which require higher levels of cognitive
thinking. In addition, many errors are not due to lack of knowledge but
appear to be based on over-generalisation of algebraic rules.
Suggestions for practice based on these findings are provided.
