Researches on teachers’ thought processes have shown that teachers are reflective, thoughtful
individuals who are constantly involved in problem solving and decision making (Clark & Peterson, 1986;
Shavelson & Stern, 1981). For instance, when a new topic is introduced into the Mathematics
curriculum, a teacher will have to be involved in decision making as to the depth of content to teach, the
amount and selection of enrichment material among others. With the inclusion of new topics into the
new Mathematics curriculum, it might be interesting to examine how teachers response to the changes.
This is the main objective of this paper.
