Development of Habits Through Apprenticeship in a Community: Conceptual Model of Physics Teacher Preparation
Eugenia Etkina, Bor Gregorcic, Stamatis Vokos
We propose the DHAC conceptual model of teacher preparation (Development of Habits through Apprenticeship in a Community), which builds on the contemporary literature on teacher pr…
Energy conservation in dissipative processes: Teacher expectations and strategies associated with imperceptible thermal energy
Abigail R. Daane, Sarah B. McKagan, Stamatis Vokos +1
Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elem…
Goals for teacher learning about energy degradation and usefulness
Abigail R. Daane, Stamatis Vokos, Rachel E. Scherr
The Next Generation Science Standards (NGSS) require teachers to understand aspects of energy degradation and the second law of thermodynamics, including energy's availability and…
Student understanding of time in special relativity: simultaneity and reference frames
Rachel E. Scherr, Peter S. Shaffer, Stamatis Vokos
This article reports on an investigation of student understanding of the concept of time in special relativity. A series of research tasks are discussed that illustrate, step-by-st…
The challenge of changing deeply-held student beliefs about the relativity of simultaneity
Rachel E. Scherr, Peter S. Shaffer, Stamatis Vokos
Previous research indicates that after standard instruction students at all academic levels often construct a conceptual framework in which the ideas of absolute simultaneity and t…
Long Range Forces in Quantum Gravity
Ivan J. Muzinich, Stamatis Vokos
We calculate the leading quantum and semi-classical corrections to the Newtonian potential energy of two widely separated static masses. In this large-distance, static limit, the q…
