Extending Prospective Secondary Teachers’ Example Spaces for Functions
Page: 352
The focus of this study is on secondary school teachers’ example spaces for the concept of a function. This is examined via participants’ responses to a scripting task – a task in which participants are presented with the beginning of a dialogue between a teacher and students, and are asked to write a script in which this dialogue is extended. The examples for a function under certain constraints provide a lens for examining participants’ concept images of a function, as well as what they perceive to be concept images of their students. These scripts are then used as a springboard for extending participants’ example spaces.
