One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

Biosphere contamination is a current environmental and social issue that must be included in the school programme. It is essential that students recognise their responsibility, and be knowledgeable about the generation and reduction of environmental pollution. Dyes are usually used in school activities and discharged into household effluents,…

Ever since Newton's groundbreaking work on the composed nature of light, additive colour mixing (and its laws) are subject to the interest of physicists as well as other sciences. In this paper, we present a setup for simple lab or home experiments on additive colour mixing and the laws of colour mixing. Students use the screen of a laptop or…

This paper demonstrates the use of a smartphone as a low-cost multi-channel optical fibre spectrophotometer suitable for physics laboratory classes. A custom-designed cradle and structure support were fabricated using 3D printing. The plastic optical fibres were arranged and inserted into the hole of the cradle to guide the light to the rear…

Mobile phones are a widely used platform for educational apps, mobile health, and a variety of chemical tests. Here, we are working on a mobile phone-based physics lab (mPhysics) that uses a mobile phone's capabilities to run simple physics experiments and demonstrations. While a mobile phone can be used to analyze magnetic and optical properties…

Diagrams have been used for instructional purposes for many years and recent advancements permit the design of an idea by a wider range of diagrams for easy understanding. The study employed an experimental design to examine the effectiveness of computer-based concept maps (CBCM) on students' cognitive learning of colours. A quasi-experimental…

Technological developments allow students to access visual information from digital devices as small as phones or as large as whiteboards. Education technology research and policy typically address the software product, yet little research has focused on optimal viewing parameters or the impact it has on student users. Students with light…

Post-school outcomes in the areas of health, safety, and independent living are poor among students with complex communication needs and autism spectrum disorder, particularly for those in rural areas. This study examined the comparative effects of print versus digital technology instruction on participants' cumulative accuracy of answering Wh-…

This volume focuses on the implications of digital technologies for educators and educational decision makers that are not widely represented in the literature. The chapters contained in the volume are based on the presentations at the 2020 edition of the CELDA conference and cover multiple developments in the field such as deploying learning…
