Research has shown that asking conceptually based questions along with a personal response system (clickers) is an effective way of implementing the peer instruction pedagogy. Lecture tutorials are a paper-based method that also incorporates peer instruction. Past research has shown that both methods yield significant learning gains for students…

This article discusses the development of beginning physics teachers' pedagogical content knowledge (PCK) in the context of teaching basic electricity during a one-year Professional Graduate Diploma in Education (PGDE) course and beyond. This longitudinal study used repeated semi-structured interviews over a period of four-and-a-half years. The…

According to the actuality of Dezhou University, some useful reforms in teaching content, teaching method, and teaching measure are introduced, combining with the characteristics of the course of quantum mechanism in this article.

Readily available software designed for the production of music can be adapted easily to the physics classroom. Programs such as Apple's GarageBand access large libraries of recorded sound waves that can be heard and displayed both before and after alterations. Tools such as real-time spectral analysers, digital effects, and audio file editors…

The phenomenon of weightlessness is known to students thanks to videos of amazing things astronauts do in spaceships orbiting the Earth. In this article we propose two hands-on activities which give students opportunities to infer by themselves the absence of buoyant force in a gravity accelerated system. The system is a free-falling or vertically…

It might be said that physicists experience life somewhat differently from other people. Whether turning a corner in a car or observing a sunset there is an inherent need to understand, as well as to appreciate, the beauty of everyday life. There is no better an example of this than the rides in a children's playground. The playground holds a…

Two experiments are proposed to study Boyle's law and the pressure law in a school laboratory. The peculiar feature of the experiments is that the value of the pressure and of the volume are obtained respectively by means of a force and a position sensor, thus allowing students to connect, in an experimental context, mechanics variables, such as…

By means of a simple mathematical model developed by the authors, the apparent movement of the Sun can be studied for arbitrary latitudes. Using this model, it is easy to gain insight into various phenomena, such as the passage of the seasons, dependences of position and time of sunrise or sunset on a specific day of year, day duration for…

We investigated changes in movement kinematics and attentional focus when expert and novice golfers performed a golf-putting task under pressure. Six male professional golfers and five male novice golfers performed 100 acquisition trials, followed by 10 trials in the pressure condition with a performance-contingent cash reward and small audience.…

Since the formation of atomic bonds is active, the authors sought a way of learning through drama or kinetic activity. To achieve this goal, they developed an activity called Romance of the Atoms. The activity requires students to use computer-animation technology to develop short cartoons that explain atomic classification and bonds. This…

Making a loudspeaker is a very rewarding hands-on activity that can be used to teach about electro-magnetism and sound waves. Several loudspeaker designs have been described in this magazine. The simplest loudspeaker has only a magnet, a coil, and three plastic cups. The simpler devices require a powerful amplified output, e.g., from a boom box.…

First-year physics laboratories are often driven by a mix of goals that includes the illustration or discovery of basic physics principles and a myriad of technical skills involving specific equipment, data analysis, and report writing. The sheer number of such goals seems guaranteed to produce cognitive overload, even when highly detailed…

We examine the pedagogical suitability of introducing a teaching sequence for the concept of electrical capacitance within the context of charging a body. This short sequence targets first year university students and was designed following students' common conceptions on this topic. The evaluation is made by comparing the results with a control…

This case study's primary objective is to describe the implementation of the electronic response system (clickers) in a small (N = 25) second-year physics course at a large public university and to draw attention of the science faculty who teach upper-level science courses to the potential benefits of this pedagogy. This pilot study discusses the…

This study presents and interprets some conceptual difficulties junior-level physics students experience with Ampere's law. We present both quantitative data, based on students' written responses to conceptual questions, and qualitative data, based on interviews of students solving Ampere's law problems. We find that some students struggle to…
