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…

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…

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…

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…

Diffraction is an important phenomenon in physics. This paper describes using a scanning electron microscope (SEM) to produce cross-sectional images of iridescent seashells. When seashell cross-sections are viewed in a SEM, regular structure is seen. Seashells are a good example of a biocomposite material and good natural objects for introducing…

In this article, a consecutive series of four hands-on experiments are recommended to teach the colors of paint/pigment and their mixtures. These activities, which are effective in learning about how to make a simple observation and help to build argument-based knowledge about colors, offer an integrated and innovative way of teaching colors of…

Polarization of light is one of the topics in the Croatian high school physics curriculum. It is taught in the final year of high school education. Twenty-seven Croatian high-school students (aged 18-19 years) were interviewed after regular instruction about their understanding of polarization of light and the model of light itself. This paper…

Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

The topic of atomic spectra is part of university and secondary school curricula around the world. Relatively little research, however, has been done on the learning and teaching of this subject, despite the fact that it forms a foundation for advanced study in quantum mechanics, astronomy, and astrophysics. A systematic investigation into student…

This study investigates the effects of smart classrooms, comprehensive assessment management information systems, and remediation teaching techniques on teachers 'and student's conceptual understanding of physics. The participants included 67 students from Senior One, Senior Two, and Senior Three, purposively sampled from G.S Mushongi in Kirehe…

The research study concentrates on the incorporation of case technology to augment the enhancement of research competencies among future physicists. The study scrutinizes the influence of case technology on students' research capabilities and their aptitude to apply theoretical knowledge to practical situations. The main objective was to identify…

The Arduino board and its communication with several sensors are becoming more and more popular in the physical science community. They offer inspiring possibilities for learning different physical concepts. In this article, we focused on creating a very practical educational system for experimenting with diffraction of laser light and graphically…

STEM is about the integration of science, technology, engineering and mathematics. To teach STEM effectively, students need practical examples of subject integration. A good example is the use of an electron microscope in teaching physics and biology. An electron microscope is an instrument in which the operation depends on electromagnetism and…

While interdisciplinary approaches in the STEM subjects are widely advocated there are concerns that disciplinary learning can be compromised, especially in mathematics. The Interdisciplinary Mathematics and Science (IMS) project is a three-year longitudinal study in four Victorian primary schools that has developed a pedagogical approach to…
