The Importance of Teaching Quantum Mechanics in Secondary School and Investigating Students' Misunderstandings in Wave-Particle Duality

At the beginning of the 20th century, the advent of quantum mechanics changed the science of physics fundamentally. The amazing properties observed in quantum phenomena have attracted the attention of many researchers in industry and medicine. Today, progress in many different sciences due to the advent of quantum mechanics. Due to the application of quantum science in various fields, teaching quantum mechanics concepts, which are very different from classical concepts and in some cases are unacceptable, has special importance. In this paper, we examine the teaching of quantum mechanics in secondary school textbooks. Then, for instance, we examine the level of understanding of secondary school students in the concept of wave-particle duality with a few questions.
