摘要：Recent studies have pointed out that many schoolchildren do not master the
skill of solving non-routine mathematical problems. In this article, a trial study designed to
encourage seventh and eighth grade students to learn and use problem solving strategies is
discussed. The strategies consist of six heuristic strategies known as Simplify the Problem,
Guess and Check, Look for a Pattern, Make a Drawing, Make a Systematic List and Work
Backward. Classroom activities consisted of a short whole-class introduction, group studies
and a final whole-class discussion on the given problem. The teacher’s role was to encourage
and guide the pupils towards engaging in the problem. It is observed that in these classes some
of these strategies are effective in learning, others are not.
