Conceptual Maps and Integrated Experiments for Teaching/Learning Physics of Photonic Devices

This paper presents the experimental approach and an example of using conceptual maps as a method based on constructivist mode of learning, teaching and researching knowledge of quantum Physics, using photonic devices. Understanding the Planck relationship, which links energy and frequency as a result of quantification of the energy, is a crucial step. It is one of the most famous examples of the corpuscular nature of light, which led to the development of quantum mechanics in the early 20th century, and whose explanation is still the standard in teaching Physics in high school. The paper also presents the verification of Einstein's theory and determination of Planck's constant using electroluminescent phenomenon for LEDs of different colours. Conceptual maps are a powerful tool not only for perceiving, representing and achieving knowledge, but also for creating new knowledge. It is essential helping students to understand that all concepts are somehow related to each other. Selecting cross-links as specific as possible and identifying the most appropriate linking words to connect concepts are crucial aims. CmapTools software tool can serve as a basis for a new kind of integration of Internet resources and all classroom experiences, inside Physics laboratories, and outside them. If it is used in conjunction with conceptual maps designed to support learning, it provides a new educational model.
