Research in the Resources Framework: Changing environments, consistent exploration
Michael C. Wittmann
In this paper, I discuss my personal journey through one research tradition, that of the resources framework, and how it has evolved over time. In my present work, understanding le…
Probing Student Understanding With Alternative Questioning Strategies
Jeffrey M. Hawkins, Brian W. Frank, John R. Thompson +2
Common research tasks ask students to identify a correct answer and justify their answer choice. We propose expanding the array of research tasks to access different knowledge that…
Students' Consistency of Graphical Vector Addition Method on 2-D Vector Addition Tasks
Jeffrey M. Hawkins, John R. Thompson, Michael Wittmann
In a series of ten two-dimensional graphical vector addition questions with varying visual representations, most students stuck to a single solution method, be it correct or incorr…
Students' Responses To Different Representations Of A Vector Addition Question
Jeffrey M. Hawkins, John R. Thompson, Michael C. Wittmann +2
We investigate if the visual representation of vectors can affect which methods students use to add them. We gave students one of four questions with different graphical representa…
Using conceptual blending to describe emergent meaning in wave propagation
Michael C. Wittmann
Students in interviews on a wave physics topic give answers through embodied actions which connect their understanding of the physics to other common experiences. When answering a…
Understanding the use of two integration methods on separable first order differential equations
Katrina E. Black, Michael C. Wittmann
We present evidence from three student interactions in which two types of common solution methods for solving simple first-order differential equations are used. We describe these…
