Introduction

How can we help students understand graphs and overcome some of the conceptual difficulties they have?
In this rigorous study the researcher investigated whether mathematics instruction based on questioning that targeted students’ knowledge about their mathematical thinking (metacognitive questioning) would promote students’ learning and enhance their understanding of graphs.  (Examples of metacognitive questions are: ‘Does this make sense?  Why is s/he doing it that way?  What did I/we do last time we had a similar problem?).  Students used such questioning approaches within small group learning situations in which they worked together to solve the same problem (co-operative learning).  The research focused on 196 (Year 9) students and six teachers in two schools.  The study found that the students significantly improved their understanding about how to interpret and construct graphs.  Research evidence also showed that co-operative small group working structured through metacognitive questioning engaged more students and produced more elaborate verbal contributions from the participants when compared to the control groups.
