Abstract
The results of a two-year professional development progrdl11 in teaching mathematics
for intermediate and secondary school teachers showed that the intermediate school
teachers involved changed less than did the secondary school teachers. The limited
mathematical knowledge of the intermediate school teachers was seen as a major
constraint preventing them from making changes consistent with a constructivist
approach to learning as recommended in a new national mathematics curriculum.
Their limited mathematical knowledge tended to result in a narrow perception of
mathematics and mathematics learning. They tended to reflect upon their classroom
teaching more in terms of attitudes toward mathematics than in terms of values drawn
from a broad mathematical knowledge. This reflection in terms of attitudes was
unlikely to lead to improvement in their students' learning.
