**Research Interests**

**Research Interests**

Physics Education Research – research on the learning and teaching of physics – including research-based curriculum development.

- Student mathematical modeling, and student sensemaking and reasoning at “the mathematics-physics interface”: how student understanding of mathematics concepts influences understanding of physics concepts, and vice-versa; how students apply mathematics to physical situations; how students make physical meaning of mathematics.
- Learning and teaching of specific physics concepts at the undergraduate level, at introductory and advanced levels. Identifying specific student conceptual difficulties, and addressing difficulties through development of guided-inquiry instructional materials.

**Research**

*Current active research topics*

#### Student understanding at the interface between mathematics and physics concepts, especially of mathematics that is relevant for understanding certain physics topics

- student reasoning with mathematics in quantum mechanics, especially eigenequations
- student connections between vector calculus and physics contexts
- the extent to which, and how, students evaluate problem solutions
- using symbolic forms and conceptual blending in modeling equation construction
- integration in the context of process variables and state functions

*Prior and recurring research topics*

- construction and use of multivariable coordinate system differential elements
- understanding and application of the Fundamental Theorem of Calculus based in graphical representations in mathematics and physics
- partial differentiation in the contexts of material properties and the Maxwell relations
- use of Taylor series expansions in statistical mechanics (article)

- probability in the context of statistical distributions

*Previous projects*

#### Student understanding of thermal physics at advanced undergraduate levels in physics

(project overview poster)

- work, heat transfer, and internal energy, especially related to the use of pressure-volume

*(P-V)*diagrams - entropy and the Second Law of Thermodynamics
- student models for entropy, in the context of ideal gas processes
- student application of the Second Law to heat engines and thermodynamic cyclic processes (article)
- comparisons of student understanding across chemical engineering, mechanical engineering and physics

#### Understanding of teaching and learning in physics by graduate students and teachers, and the interplay between *specialized content knowledge* and *pedagogical content knowledge* (knowledge of the teaching and learning of a topic).

- The relationship between teacher content knowledge, teacher pedagogical knowledge, and student learning, in middle school physical science, in force and motion
- Part of the Maine Physical Sciences Partnership

*Other topics of interest*

- Student understanding of magnetic fields and representations thereof, and in particular of the magnetic structure of flexible refrigerator magnets
- Student understanding of concepts in 9th- and 12th-grade physics courses:

investigating the*Physics First*movement - Student understanding of vectors and vector operations
- Student understanding of two-dimensional kinematics, including the context dependence of that understanding and the interpretations of different representations. Development and assessment of curriculum that emphasizes conceptual understanding and transfer to different contexts.
- Conceptual understanding of sound at both the introductory level and among preservice and inservice K-12 teachers. Development of curriculum on sound aimed at elementary teachers, and on longitudinal waves aimed at introductory physics students.
