Recent curriculum reforms in some Australian states e. Department of Education Tasmanian, have highlighted the importance of thinking, communicating and instilling deep understanding in our students and have seen a re-emphasis on mathematical problem solving as an important mechanism for enhancing these skills.
Problem solving is, of course, not a new idea in mathematics education. Polya and others e. Students can talk about the problem to understand it better and to clarify the method.
They included such things as an ability to articulate understanding, to respond to probing questions, to explain concepts in their own language, and the ability to teach the relevant concept to others Mousley, However, some students express a dislike for writing explanations and justifications in mathematics and according to Bicknellmany students find writing explanations a difficult and tedious exercise.
Kaur and Blane found 95 that it was often difficult to diagnose the difficulties experienced by students in solving problems by examining their written solutions alone. Their study aimed to determine whether or not students who gave correct answers to pen and paper tests had a comprehensive understanding of the mathematical concepts and relationships which the tests were designed to measure.
According to Huniker and Laughlinstudents become aware of what they really know and what more they need to know as they talk about their experiences and test their new ideas with words.
Ginsburg also advocated the interview as an effective means to enable students to communicate their mathematical thinking and Norbury recommended its use particularly with younger children. The Study The study examined the use of problem solving strategies by Grade six students and their ability to communicate their thinking both verbally and in writing.
The specific research question addressed in this paper is: Does reliance on written recordings of the problem solving process differentially disadvantage students according to their mathematical ability?
Subjects Four grade six students were selected from each of five primary schools, making a total of twenty students 12 girls and eight boys. Grade six students were targeted because they could be expected to have a sufficient level of literacy in order to be able to record their solutions in writing.
Teachers in each school were asked to nominate the four students who would participate in the study. The problems are listed below. Jenny is making towers of cubes using red, blue, yellow and green.
How many different towers can she make by changing the order of the colours? Jim got into a lift. He went down five floors, up six floors and down seven floors. He was then on the second floor. At what floor did he get on? Susan worked at an apple orchard.
When she was sorting the apples for sale, she noticed that two out of every seven apples had worm holes. Some children were playing with some rabbits in a yard.
I tried to count them and found that there were 30 legs and 11 heads. How many children and how many rabbits were in the yard? If there were ten people at the meeting, how many handshakes were there?
I made some triangles using matchsticks. I used three matches to make one triangle, five to make two triangles and seven to make three triangles.
If I continued in this way, how many matches would I need to make 12 triangles?
Procedure Students were interviewed using a semi-structured approach Burns, A copy of each problem was presented and read aloud to the student by the interviewer. The student was then asked to solve the problem and to make a written recording of any working that they used in this process.
Potentially helpful concrete materials such as cubes, counters and matchsticks were available to be used as the students chose and in relation to any of the problems.
Following the completion of each problem, each student was asked to verbally explain what they had done, referring to their written solution as they wished, while the interviewer tape recorded their responses, made observational notes and asked prompting questions when and if clarification was required.
These scales were also used by Adibnia and Putt in their study of problem solving by year six students. Judgments of the clarity of the communication were made independently of an assessment of the correctness of their solutions.
So he got on at the 12th floor.Beswick, K and Muir, T, Talking and Writing About the Problem Solving Process, Proceedings of the 27th Annual Conference of the Mathematics Education Research Group of Australasia, June , Townsville, Australia, pp.
