Χρήση Μικροελεγκτή Micro:bit για τη Διδασκαλία Φυσικών Επιστημών: Μελέτη Περίπτωσης Μαθήτριας με Αναπηρία Όρασης

Abstract

This research is a case study of a student with a visual impairment and examines whether the use of microcontrollers, such as the micro:bit, affects her understanding of natural phenomena such as the alteration of day and night and the succession of seasons. The aim of the research is to show how technology can enhance learning, engagement and autonomy for students with visual impairment by providing accessible and experiential learning experiences. The study includes two specially designed activities according to the principles of the 5E model that focus on understanding the phenomena of day-night and seasonal change, using micro:bit and haptic models as main tools. The micro:bit was used to provide acoustic feedback on brightness, while haptic models supported the understanding of the position and motion of the Earth relative to the Sun. The research was based on semi-structured interviews and observations, which were analysed through thematic analysis. The results show that the use of the micro:bit facilitated learning, enhanced the student's autonomy and provided her with a hands-on experience. The research suggests the incorporation of such tools to create an inclusive educational environment in science where students with visual impairment participate equally and actively.
