Abstract
Over seven months, one group of Year 7 students showed little, if any,
progress with algebra while another group improved markedly. The latter
were significantly better in developing substitution skills, in identifying
when two algebraic expressions were equal, and in understanding algebraic
symbols as generalized numbers and/or variables and as representing numbers
rather than objects. The former were significantly more inclined to persist
with incorrect pre-algebra .ideas and to interpret conjoining (e.g., in '2n') as
addition. They were not coping with the new ideas being presented to them.
