Graduate Teaching Assistants' Statistical Knowledge For Teaching, Jennifer Ann Noll
Graduate Teaching Assistants' Statistical Knowledge For Teaching, Jennifer Ann Noll
Dissertations and Theses
This dissertation explores graduate teaching assistants’ (TAs’) statistical knowledge for teaching. Data collection methods that enabled the exploration of TA s’ statistical knowledge for teaching include: (a) a task-based web survey administered to 68 TAs from 18 universities across the United States; and, (b) a series of three taskbased interviews with a subset of five TAs from the larger survey population. Through and Strauss, 1967), I investigated the ways in which TAs reason about sampling tasks, and how they think about teaching and student learning in relation to sampling ideas. Building on past research in statistics education on K-12 and …
A Qualitative Analysis Of Hybrid Control Systems, Anca Georgeta Williams
A Qualitative Analysis Of Hybrid Control Systems, Anca Georgeta Williams
Dissertations and Theses
Hybrid Control Systems are increasingly investigated as models for control systems where the interaction between continuous and discrete processes is tightly integrated. As yet, there is no general agreement as to what constitutes a canonical hybrid system. Rather various subclasses of systems combining continuous evolution and discrete event characteristics are analyzed for each application. In this dissertation we first unify the presentation of hybrid systems with a rich model which encompasses most examples of interest. We classify the available results and show how they fit together within the different subcategories. In the main part of the dissertation we prove that …
