Problem Solving Enhances Children's Numeracy Learning: Ann Gervasoni Poses Several Questions about Problem Solving and Provides Six Reasons for Supporting Her Belief That Problem Solving Enhances the Development of Numeracy and Mathematical Thinking

Article excerpt

Numeracy is tied to human intentions. It is about effectively using mathematical insights, understandings and skills to solve the problems we face during the activities of the day. Problem solving is therefore inextricably linked to numeracy.

For a number of years in Australia, problem solving has been emphasised as an important aspect of mathematics education. It is argued that a problem solving approach makes mathematical learning more meaningful and relevant for students and promotes thinking, flexibility and creativity. A problem solving approach can therefore be viewed as an important way of enhancing students' numeracy development. However, some students are horrified when the words 'problem solving' are uttered in the classroom. Consider this scenario recently described by a colleague:

   This term we have been focusing on the problem
   solving process. My P/1 children have participated
   in many input sessions where I have
   provided them with many strategies to solve problems
   e.g. draw pictures, write a number sentence,
   make a model, use a calculator, look for a pattern,
   work it out mentally. We have also worked in
   groups and individually to solve problems using
   all these strategies. My dilemma is that I have a
   student who has a fear of failure and starts to cry
   as soon as the words 'problem solving' are
   mentioned. She is a perfectionist and enjoys the
   comfort of structure, otherwise she feels threatened
   and withdraws from the grade. She becomes
   so overwhelmed and distressed that not even my
   assistance is any reassurance for her. She is a fairly
   bright student who is usually independent and
   able to cope with most of the classroom activities.

Questions to consider

What is your response to this dilemma?

What dilemmas have you faced when using a problem solving approach with your students?

What alternative course of action did you consider as a response to this dilemma?

Was the dilemma resolved?

Although most students thrive on problem solving, no doubt each of us recalls instances when students have reacted in a similar way to the student described above. It is alarming to discover that at age seven, a child can be so frightened of problem solving. Situations like this call on us to reflect on why we use a problem solving approach and whether such an approach does indeed enhance mathematical learning and numeracy development.

I believe that there is a great deal of value in using a problem solving approach to enhance numeracy development. However, for some students, problem solving involves a very different type of mathematical activity to that which they have experienced in the past. Often, mathematics tasks in classrooms consist of closed questions, which do not require complex thinking to solve, or any justification of the solution. Such questions often follow careful demonstrations and explanations by the teacher, are routine in nature and deal with aspects of mathematics pre-determined by the teacher. Hence, when students are faced with real problems, they feel quite lost. Such students need support to develop their understanding of mathematical activity.

The value of problem solving

Problem solving activities, involving problems that have no immediately obvious solution, can quite significantly change the nature and power of the mathematical thinking in which children engage at school. This, I believe, is the greatest value of problem solving.
