The COVID-19 pandemic has forced educational institutions to adjust their learning process to distance education or online learning. This paper explains how to teach optics during the COVID-19 pandemic by implementing project-based learning that can be supervised online. Students are instructed to design, characterize, and optimize droplet lenses…

Research has shown that project-based learning promotes student interest in science and improves understanding of scientific content. Fostering student motivation is particularly important in accelerated science and technology programmes for talented students, which are often demanding and time-consuming. Current texts provide little guidance on…

Ciênsação, an open online repository for hands-on experiments, has been developed to convince teachers in Latin America that science is best experienced first hand. Permitting students to experiment autonomously in small groups can be a challenging endeavour for educators in these countries. We analyse the reasons that cause hesitation of teachers…

This study was conducted to develop a simple and inexpensive experimental apparatus that can measure the position of an object moving along a straight line at certain time intervals. For the construction of the apparatus, a battery-powered toy car, a fine-tipped paint brush, gouache (or watercolour) paint and paper tape were used. The working…

This paper describes a set of simple experiments with a very low cost using a notebook as a measuring instrument without external hardware. The major purpose is to provide demonstration experiments for schools with very low budgets. (Contains 6 figures.)

Describes an educational project primarily aimed at teachers and 15 to 18-year-old students that describes the essential features of a modern high-energy physics experiment. (Author/CCM)

Describes a project on the application of the laser which aims to stimulate the interest of undergraduate students in applied physics and to demonstrate the interaction between light and ultrasonic waves by building a simple laser communication system. (SK)
