The static equilibrium properties of a spool, resting on an incline and subject to the tension exerted by a string wrapped around the core cylinder, are studied by means of Newtonian mechanics. The overall behaviour of this system is imagined to be similar to that of a doggie kept on a leash. Starting from the well-known mechanical properties of…

Active learning yields better learning outcomes than traditional, lecture-based teaching. Common approaches in large lecture courses are activating elements during the lectures and warm-up activities using online learning environments. However, implementing warm-up exercises, on which students work on by themselves makes formative feedback…

In recent years, short question-and-answer activities known as lecture tutorials that are designed to help students work with and discover concepts for themselves, rather than simply being told about them (lectured to) have become a popular tool for learner-centred teaching of introductory college astronomy. Students on such a course are usually…

The use of toys in physics teaching is common. This brief review of the physics of toys intends to show that they are not only very useful in lectures and demonstrations in order to motivate students but also very interesting from a scientific point of view. However, since their physics is sometimes too cumbersome, the effect can be the opposite.…

The reaction time of a group of students majoring in physics is reported here. Strong correlation between fatigue, reaction time and performance has been observed and may be useful for academicians and administrators responsible for working out timetables, course structures, student counsellings, etc. (Contains 5 figures, 1 table, and 1 footnote.)

Physics students were exposed to one of three lecture styles: blackboard, overhead projector, or two channel slide presentation. The latter method utilizes two slide projectors; after a slide has been discussed it is transferred to the second projector where it is displayed until the slide changes again. Student questionnaires revealed a…
