Developing students' ability to troubleshoot is an important learning outcome for many undergraduate physics lab courses, especially electronics courses. In other work, metacognition has been identified as an important feature of troubleshooting. However, that work has focused primarily on "individual" students' metacognitive processes…

This paper describes a small-scale piece of research using concept mapping to elicit A level students' understandings of particle physics. Fifty-nine year 12 (16- and 17 year-old) students from two London schools participated. The exercise took place during school physics lessons. Students were instructed how to make a concept map and were…

The double-wall paper cup is an everyday object that can be used in the laboratory to study heat transfer. The experiment described here has been done by physics students aged 12-13 years; it can also be used in a different context to prompt debate about environmental issues.

This overview is intended to help colleagues achieve successful and satisfying observations using a ripple tank. There are many observations to consider that can effectively illustrate reflection, refraction, interference and diffraction, but the most important consideration is to make every effort to enable students to see the effects we want…

The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

Full shadows, partial shadows and multilayer shadows are explained based on the phenomenon of the linear dispersion of light. This paper focuses on progressing the understanding of shadows from physical and mathematical perspectives. A significant relationship between light and color pigments is demonstrated with the help of the concept of sets.…

Practical solid state diodes and transistors have made glass valve technology nearly obsolete. Nevertheless, valves survive largely because electric guitar players much prefer the sound of valve amplifiers to the sound of transistor amplifiers. This paper discusses the introductory-level physics behind that preference. Overdriving an amplifier…

Most students cannot understand the concepts of science concepts. The abstract concepts that require visualization help students to promote to the understanding about the concept. The aim of this study was to develop Virtual Microscopic Simulation (VMS) in terms of encouraging conceptual change and to promote its effectiveness connected to…

The number of both astronomy bachelor's degrees and PhDs awarded in the class of 2016 represent all-time highs. Astronomy bachelors have been increasing steadily for the last 15 years, with 469 degrees awarded in the class of 2016. With undergraduate astronomy enrollments continuing to grow, the trend is expected to continue for at least the next…

This study explores the understanding levels of pre-service teachers of the elementary school mathematics teacher education undergraduate program about capacitors that they learned in the compulsory Physics-2 course in the second year of the second term, and instructors' predictions about the teachers' responses. A total of 54 pre-service teachers…

In recent years, while the context-based approach has been popular and the teachers have been using it in the classrooms, it is seen that they do not prefer using context-based evaluation techniques. This becomes a problem for students because they used to be taught in the context-based approach enriched by daily life examples and then they are…

The Billotron is a device designed and built by the LPC Caen to illustrate the methods with which physicists are able to study the basic structure of matter, in particular the nucleus of the atom.

It is well known that "interactive engagement" helps students to understand basic concepts in physics. Performing experiments and analyzing measured data are effective ways to realize interactive engagement, in our view. Some experiments need special equipment, measuring instruments, or laboratories, but in this activity we advocate…

This article describes the redesign of a project-based course on soft and biological materials to include computational modeling. Including the construction of computational models in the course is described as a shift from constructivism--a theory that characterizes the development of formal reasoning, to constructionism--a theory that focuses on…

Effective faculty professional development must be participant centered; tailored to the needs and interests of the faculty who engage in it. In order to better understand those needs and interests, we investigate how knowledge, attitudes, beliefs, and teaching practice vary among new physics faculty, using surveys of a large sample (n = 442) of…
