Promoting IoT Education for Pre-university Students With Coloured QR Codes : Colour multiplexed QR codes

Internet of Things (IoT) is certainly a relevant concept in the education of the future engineering students, providing important instruments to adapt the teaching and learning methodologies. Among those instruments, QR codes are unique tools due to its intrinsic properties such as fast and easy readability and larger information storage capacity, in parallel with its increasing popularity in the last years associated to daily routines as they offer a simple physical means for quick access to web sites. We propose a project-oriented approach tailored for pre-university students to develop their skills in the field of IoT, namely, programming and prototyping development in straight connection with school activities. The students' experimental assessment of the project-based learning was complemented by the expertise of the team from the University shortening the classical loop between the student problem solution and teacher feedback. It was observed a fruitful improving of the students self-awareness and of their overall performance in multidisciplinary issues in the field of IoT contents, with impact in the school day life and promoting the engagement in Engineering University level degrees.
