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 …

A Study Of The Emergence Of Student Tacit Knowledge In Response To Environmental Images And Science Instruction, Rory J. Glass
Legacy Theses & Dissertations (2009 - 2024)
The purpose of this study was to identify the presence of students’ tacit understandings as they apply to environmental science content, and to discover how these understandings emerge and are viewed and interpreted by teachers.

Additionally, interviews were conducted with 15 students and two teachers to gain insight into their thinking on an array of topics related to the environment and environmental reasoning. It was hypothesized that students’ understandings and teachers’ interpretations of them may be influenced by their …
