In this article, we outline how we implemented an honors-level add-on course to complement standard university-level introductory physics courses. We explain why it was necessary to do this. We then explain the strategies we have adopted for attracting students, engaging them, and assessing their performance. Our goal in creating this course was…

Practical work must be assessed in a way that will promote the development of key skills necessary for destinations beyond the physics school laboratory. This paper reports on a study which sought to find out teachers' views and practices on the assessment of Advanced Level ('A' level) physics students' practical work skills. Individual interviews…

In this work three examples of textbook circuits (resistor-capacitor, resistor-inductor and resistor-inductor-capacitor) have been modeled by employing the Euler method for the approximate solution of differential equations using algorithms implemented in the "Python" programming language. The aim of this work was to demonstrate how…

This paper is about an experimental problem on forced oscillations, which was given to 14-year-old primary school pupils at the Slovenian national (final) level of the physics competition in April 2019. At the time when the competition took place these pupils were approaching the end of the school year, when they encountered physics as a school…

When Chief Justice of the Supreme Court John Roberts asked in the 2016 affirmative action case "Fisher v. University of Texas," "what unique perspective does a minority student bring to the physics classroom?" the Equity and Inclusion in Physics and Astronomy group replied by rejecting the premise of the question itself.…

In general, undergraduate experimental physics laboratories do not usually have experiments designed to address rolling friction and to measure the value of the rolling friction coefficient. This work explores an experiment, which has the potential to arouse students' curiosity about rolling friction by addressing a counterintuitive aspect of the…

This study aimed at determining the effectiveness of self-questioning strategy in developing independent thinking in teaching physics. The researcher used the Independent Thinking Test on a purposive sample consisted of (46) students from the first secondary scientific class in Amman schools in Jordan. A quasi-experimental approach was adopted. To…

The infrared camera, or thermal imaging camera, can be used to complement the teaching of a number of topics in high school science. Here, we provide seven examples of its application in teaching physics, chemistry and biology concepts at high school level. We also discuss its strengths for such applications and provide some pointers for science…

Error analysis consumes much of the focus in introductory physics labs. Catastrophic cancellation is a spike in error that occurs when subtracting two measurements of roughly equal magnitude. Often termed "loss of significance" or "subtractive cancellation," this effect can easily relegate experimental results to utter…

When the relationship between two physical variables, such as voltage and current, can be expressed as y = bx where b is a constant. b may be estimated by least squares, or by averaging the values of b obtained for each x-y data pair. We show for data gathered in an experiment, as well as through Monte Carlo simulation and mathematical analysis,…

Recently, Nissen et al. argued in this journal for the use of Cohen's d, in place of the more commonly used normalized gain, in the analysis of preinstruction and postinstruction scores on concept inventories used to measure the effectiveness of instruction. Their reason for advocating such a change is that they say normalized gains are…

The study aimed at detecting the level of reflective teaching practices used by science teachers in classrooms. It sought to examine the potential alteration of these practices in terms of some variables, namely gender, qualification, experience, and load. The population consisted of all science teachers of physics, chemistry, and biology in the…

Light rays refract when passing through pockets of transparent fluids with different indices of refraction such as ordinary air pockets of varying temperature. This phenomenon makes night stars twinkle, distorts views above hot asphalt roads and hot barbeque grills, and provides an opportunity for visualizing the normally invisible movement of…

The topic of atomic spectra is part of university and secondary school curricula around the world. Relatively little research, however, has been done on the learning and teaching of this subject, despite the fact that it forms a foundation for advanced study in quantum mechanics, astronomy, and astrophysics. A systematic investigation into student…

Powerbanks differ in the amount of energy they can store. Usually this capacity (in a colloquial sense) of the powerbanks is stated in the form of charge in mAh for effective advertising. From a physical point of view, shouldn't the energy that a powerbank can provide be of interest? For students, charging smartphones with power banks is…
