Abstract
In response to misconceptions students hold with understanding the concept of a variable new
teaching approaches have been introduced into many Australian Schools. These approaches
entail generalising from visual patterns and tables of data. While recent research has reported
many of the difficulties students experience with these new approaches, it has failed to delineate
why these difficulties are occurring. It seems that these approaches call on an array of reasoning
processes that, in the past, have not been considered as important to the algebraic domain. This
paper delineates some of these processes and pinpoints particular characteristics of successful
students.
