..., such as wave propagation, frequency, wavelength, reflection, refraction, superposition, and interference. We will summarize the most important research by topic and year to facilitate the following of a logical progression. Wave creation, propagation, and shape Research on students' reasoning on the creation...

... for their studies. The majority of them describe the current knowledge about the state of students' understanding of certain optics concepts, such as light propagation (Chu et al., 2009), interference of waves ( Susac et al., 2020 ), or image formation ( Tao, 2004 ). In the articles, the authors...

...) and What is polarization of light? In the experimental task, the students were to design and perform an experiment. The authors expected the students to take the known polarizer and place one of the unmarked slides in front of it, but many of the students misapplied their knowledge of geometrical and wave...

... ). The students start by working through the classic problem of transverse waves propagating without dissipation in a rope under tension. Using the Interactive Lecture Demonstration (ILD) approach ( Sokoloff and Thornton, 1997 ), the students observe the standing waves in a rope and locate the frequencies...

...) In the matter–wave ontology, the wave function is a real physical entity. An electron actually propagates through both slits and interferes with itself. In the measurement, the collapse also implies the collapse of the system. The instantaneous transition from a non-localized to a localized state...

... depending on the goal or aim of the lessons. Singapore The curricular study in Singapore ( Caleon and Subramaniam, 2010 ) explored the “learned curriculum” in the content domain of the properties and propagation of mechanical waves. To better evaluate this curricular aspect, the author considered what...

.... Gratings are well established with widely used commercial products ranging from wavelength division multiplexing (WDM) filters to semiconductor diode lasers ( ThorLabs, 2015 ). The grating couplers provide momentum change to match the incoming wave vector, for example, from a fiber, to the propagation...

... ( Podolefsky and Finkelstein, 2006 , 2007a , 2007b ). They started by examining students' answers to conceptual questions about electromagnetic waves across three treatments: a tutorial that included an analogy to waves in a string, a tutorial that included an analogy to sound waves, and a tutorial...

...' resources, inequities, oppressions, and injustices transcend the “pieces” we leverage when making sense of physical phenomena. For instance, it may be productive to build on a student's cultural experience with sound production as part of a unit on wave propagation, but recognizing those resources may...
