Developing & Describing The Use & Learning Of Conceptual Models For Integer Addition And Subtraction Of Grade 5 Students, Nicole Marie Wessman-Enzinger
Theses and Dissertations
This dissertation reports the results of a teaching experiment, which explored student thinking about integer addition and subtraction. Through the lens of commognitive theory (Sfard, 2008), interpreting negative integers as secondary intuitions (Fischbein, 1987), and employing teaching experiment methodology (Steffe & Thompson, 2000), this study was a first step in developing more robust descriptions of students' conceptual models for integer addition and subtraction. I investigated: (a) the conceptual models that students exhibited, (b) the various ways that students utilized conceptual models while learning about the addition and subtraction of integers, and (c), the ways that students' conceptions evolved over the …

The Role Of Awareness Of Repetition During The Development Of Automaticity, Emma Shadbolt
Theses : Honours
Investigation into the influence of contextual information on performance of an automatic task has found inconsistent results. The majority of studies have investigated whether changing the context of a simple cognitive task can inhibit an automatic response, but do not review whether context can help the development of automatic responding. The current study examined whether bringing awareness to the context of a simple numerosity task could aid the development of automaticity. It also examined whether participants were aware of when automaticity developed for them via a post-test interview. The numerosity task used in this study was a simple counting task …
