Abstract
(A report of progress in a Doctor of Education research project supervised by Professor Kaye Stacey.)
The paper provides an overview of some of the outcomes of an investigation comparing the
teaching of negative number at junior secondary level using tiles, as discrete integer
entities, with other teaching approaches more commonly used. The experimental approach
seems to have facilitated better performance for average ability level students. For more
able mathematics students the topic does not appear to be difficult and such students, in .
both experimental and control groups, indicated good levels of general topic mastery.
