Stoeckel, Marta R. – Physics Teacher, 2018
The abstract nature of electric potential difference (voltage) can make it a difficult concept to grasp, but understanding the relative nature of voltage is central to developing a conceptual understanding of electric circuits. In laboratory situations, I see these conceptual difficulties manifest when students have difficulty placing voltmeter…

Privat, Romain; Jaubert, Jean-Noe¨l; Berger, Etienne; Coniglio, Lucie; Lemaitre, Ce´cile; Meimaroglou, Dimitrios; Warth, Vale´rie – Journal of Chemical Education, 2016
Robust and fast methods for chemical or multiphase equilibrium calculation are routinely needed by chemical-process engineers working on sizing or simulation aspects. Yet, while industrial applications essentially require calculation tools capable of discriminating between stable and nonstable states and converging to nontrivial solutions,…

Swapp, Andy; Schreuders, Paul; Reeve, Edward – Technology and Engineering Teacher, 2011
Many people use wind to help meet their needs. Over the years, people have been able to harness or capture the wind in many different ways. More recently, people have seen the rebirth of electricity-generating wind turbines. Thus, the age-old argument about technology being either good or bad can also be applied to the wind. The wind can be a…

Donley, John F.; Stewardson, Gary A. – Technology Teacher, 2010
Alternative energy sources have become increasingly important as the production of domestic oil has declined and dependence on foreign oil has increased. Historically, there have been four time periods during which the United States was in fact crippled by oil shortages. These time periods include: (1) the early 1900s; (2) World War II; (3) the…

Warren, J. W. – Physics Education, 1983
Criticizes a proposed approach to teaching physics in terms of energy carriers (SE 532 196), arguing that it requires energy to be thought of as a substance which can flow. Discusses problems related to concept formation and logical difficulties with the curriculum, considering several contradictions to physics principles which may arise. (JM)
