Hartmann, Bruno; Priemer, Burkhard – Physics Education, 2018
Research shows that energy is a concept that is difficult to understand despite different teaching approaches existing. One of the problems is seen in its rather abstract definition. In contrast, we present an approach that activates students' everyday life experiences and uses these to develop a scientific understanding by introducing energy as a…

González, Manuel I. – Physics Education, 2017
Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

Taber, Keith S. – Physics Education, 2011
Teaching about the nature of science is seen as a priority within science education, and has also been highlighted as a suitable context for challenging the most able ("gifted") learners at secondary school level. This article discusses a practical session designed to introduce the idea of physical (natural) laws. The session asks…

Heck, Andre; Vonk, Ron – Physics Education, 2009
Physics teachers often like to discuss physics concepts with their students on the basis of simple demonstration experiments. In this article, we discuss an experiment for which one only needs a few coins of the same denomination and a wooden stick: the coins are laid alongside the stick on a horizontal surface, the stick is rotated about one of…
