CONSTRUCTION OF A TRANSISTORIZED MEASUREMENT CIRCUIT FOR TEACHING SEMICONDUCTOR PHYSICS IN HIGH SCHOOL

Abstract

Technology has proven to be an inseparable element in modern society, reshaping the way we live, learn and interact, individually and collectively. In this context, Physics teaching prioritizes the substantive training of subjects capable of analyzing, reflecting and using scientific tools to solve everyday or technological problems. As current technologies are based on the semiconductor behavior of silicon and the various digital electronic automation, control, communication and information systems, present in various sectors of society, semiconductor physics represents important content for high school, allowing greater reach in scientific understanding and technological by the subject. Based on current scientific education paradigms, this article aims to highlight the results of a didactic proposal based on the design and construction of a transistorized water level measuring circuit by students in the 2nd year of high school at a state school, belonging to the Alagoas comprehensive education program (pALei), located in the municipality of Arapiraca, during the delivery of the Integrator Project curricular component, belonging to the program's diversified base. Throughout the development of the component, the students, divided into groups, were led to the question of monitoring the water level present in the school's water tank, being able to size the circuit, assemble it and carry out tests, solving the problem initially presented based on the theoretical contribution developed in the project, based on the principles of electrodynamics and the physics of semiconductors.
