This study investigated 12-13-year-old Australian students' algebraic thinking in a hybrid environment of functional and equation-based approaches to…

Analyzes student progress within the framework of models of choice based on experiences at the Open University (United Kingdom). Investigates why students choose to continue studying in light of their success or failure in previous study and suggests that mathematical models need to be further developed to assist in this field.
