Abstract
This paper reports on a current study investigating 9 to 12 year-blds' strategies and reasoning processes in solving novel combinatorial and deductive problems. Equal numbers of children were selected from low, average, and high achievers in school mathematics an.d were individually administeredfive sets of problems, namely, two sets of combinatorialproblems(2-dimensional and 3-dimensional) and thr(!e sets of deductive reasoning problems. Bothproblem types were presented in "hands-on" and written formats. The written problems were isomorphic to the hands-on examples. The nature of children's strategies and reasoning processes in solving these problems is addressed. Of particular interest are the differences in the responses' of children classified as low and high achievers inschoolmathematics.
