Educating the Educators for Introducing Internet of Things to Primary and Secondary Schools’ Curriculums

We describe an approach to continuous education course at the University of Ljubljana for training of computer science and technology teachers in primary and secondary schools. These teachers face numerous challenges how to present computer science and engineering as a dynamic and interesting field to their students. Our approach is based on idea to introduce computer science and engineering by building Internet of things devices. A low-cost open source NodeMCU hardware and firmware platform based on ESPS266 is used, that provides WiFi connectivity and Lua interpreter as programming language. Raspberry Pi is used as a central hub for IoT devices. Teachers build an IoT system for monitoring indoor temperature and humidity, outdoor temperature and controlling an air-conditioner using IR control. Finally, we present the course evaluation by the teachers.
