Social semiotic discussions about the role played by representations in effective teaching and learning in areas such as physics have led to theoretical proposals that have a strong common thread: in order to acquire an appropriate understanding of a particular object of learning, access to the disciplinary relevance aspects in the representations…

A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

This study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students' understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a…

Demonstration interviews with 27 high school students (18-19 years old) were conducted in Zagreb, Croatia, using several standard experiments on interference and diffraction of light. Students were asked for their predictions, observations, and explanations of the experiments. In this process, many student difficulties were identified, both…

This article investigates the optics conceptions of 228 Thai high school students in grades 10-12 when they attempted to explain how an object can be seen both in general and in a completely dark room. To elicit students' conceptions precisely, their confidence in giving reasons for the final two diagnostic questions is also considered. The study…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

Exposing children to STEM education from an early age increases their curiosity and interest in STEM careers. Thanks to STEM education, children learn by working like little scientists and putting forward their own scientific products. Based on this approach, the aim of this research is to raise awareness among preschool children about the concept…

Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Visual representation in school textbooks plays an important role for physics teaching and learning. The integration of graphics with text has drawn attention of physics educators in recent years due to the close relationship between graphics and relevant text. The purpose of this study is to examine visual representation of optical content in…

Storytelling has the potential to successfully convey knowledge, understanding and experiences in an unintimidating and exciting way to experts as well as non-experts in almost all fields. Storytelling's utility as an information transmission medium makes it an attractive choice for use in classrooms where knowledge sharing, and the construction…

Teaching and learning quantum mechanics is one of the most demanding educational and conceptual challenges, in particular in secondary schools where students do not possess an adequate mathematical background to effectively support the description of quantum behaviour. Educational research shows that traditional approaches, generally based on…

Although many laboratory experiments are available to illustrate spectrophotometric or fluorometric methods, few of them introduce the use of luminometry to students. Bioluminescence, a subtype of chemiluminescence, is produced when an enzyme-catalyzed chemical reaction gives rise to light emission. Despite the advantages of bioluminescent…

The digital era's technological transformation has a wide range of beneficial effects on the science learning process. Game-based learning (GBL) is the use of game design ideas to learn about some topic while pupils are striving to do their best in the process. This study was carried out with the help of Educaplay apps ("Identify Me…

Visual images are widely used in science textbooks to facilitate the understanding of abstract concept of light. This study aims to compare and analyze elementary school textbooks from Korea, the United States, and Japan, focusing on how visual images are utilized to effectively convey light-related content. The findings reveal that all three…

The purpose of this study is to determine teacher candidates' opinions on the Light and QRCode Assisted Brain Lobes and their Tasks model, which is a unique design that differentiates itself from other studies in the literature. The study employed the basic qualitative research approach. Teacher candidates studying at the Faculty of Education of a…
