ab: Summary: This study reports on the algebraic generalization strategies used
by elementary and middle/high school pre-service mathematics teachers
in Kuwait. They were presented with 9 tasks that involved linear,
exponential, and quadratic situations. The results showed that these
pre-service teachers had difficulty in generalizing algebraic rules in
all 3 types of tasks. The most difficult problems were those involving
exponents; they seemed to confuse exponential growth with the
multiplication of $n$. Although they used several strategies such as
explicit, recursive, and chunking, they tended to rely on explicit
reasoning. They saw the explicit rule as a quick and easy rule to be
used. In order to improve studentsâ€™ understanding of algebraic
reasoning, we must improve the understating of generalization.
Teachersâ€™ programs should put more emphasis on the type of content
that teachers need to learn rather than on how much mathematics credits
teachers need.
