“Philipp Lenard and Cathode Rays” - the development of comics for Physics learning

Abstract

Lenard conducted a study on the photoelectron-emitted energy that varies with the intensity of the light. Lenard observed that the maximal energy of the emitted electron was independent of the light color but noted that shorter wavelength light with higher frequency resulted in increased energy of the ejected electron. Lenard received the Nobel Prize in 1905 in recognition of his contributions to the field of cathode rays. Lenard’s research on cathode rays is a historical plot that is rarely presented on the photoelectric effect material in schools. Because of these conditions, students are less interested in studying concepts and phenomena in physics. The essential criterion for captivating visual learning media is the effective and enjoyable delivery of information. One of the strategies to enhance educational outcomes is the provision of captivating alternative learning resources, such as comics. This is because comics possess the unique ability to amalgamate information, creativity, and enjoyment, so fostering an engaging learning experience. This study resulted in comics about Philip Lenard and his research on cathode rays presented as simple cartoon images. The results of user’s perceptions show that the comics produced are worthy of being an alternative learning media in schools.
