Daane, Abigail R.; Vokos, Stamatis; Scherr, Rachel E. – Physical Review Special Topics - Physics Education Research, 2014
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 usefulness, changes in energy concentration, and the tendency of energy to spread uniformly. In an effort to develop learning goals that support teachers in building…

Scherr, Rachel E.; Close, Hunter G.; McKagan, Sarah B.; Vokos, Stamatis – Physical Review Special Topics - Physics Education Research, 2012
The nature of energy is not typically an explicit topic of physics instruction. Nonetheless, verbal and graphical representations of energy articulate models in which energy is conceptualized as a quasimaterial substance, a stimulus, or a vertical location. We argue that a substance ontology for energy is particularly productive in developing…

Scherr, Rachel E.; Close, Hunter G.; Close, Eleanor W.; Vokos, Stamatis – Physical Review Special Topics - Physics Education Research, 2012
The Energy Project at Seattle Pacific University has developed representations that embody the substance metaphor and support learners in conserving and tracking energy as it flows from object to object and changes form. Such representations enable detailed modeling of energy dynamics in complex physical processes. We assess student learning by…

Eylon, Bat-Sheva; Bagno, Esther – Physical Review Special Topics - Physics Education Research, 2006
How can one increase the awareness of teachers to the existence and importance of knowledge gained through physics education research (PER) and provide them with capabilities to use it? How can one enrich teachers' physics knowledge and the related pedagogical content knowledge of topics singled out by PER? In this paper we describe a professional…
