ERA of Students: A Class-Wise Virtual Electronics and Microcontroller Learning Platform with an AI Tutor for Classes 8–10

It is necessary to point out some limitations of the current project. Simulation program uses threshold logic but does not work with real electrical circuits, does not compile firmware and does not upload firmware into the microcontroller and hence it can be seen as the preparatory tool for practical training. Every exercise contains only one sensor and one output; there are no multiple sensors’ systems currently developed; heartbeat sensor uses only the artificial data and does not perform the medical measurements; progress is tracked on the level of the student’s browser and hence is dependent on the particular device; finally, AI tutor needs access to the platform and, just like any language model, can make mistakes. No research on the learning gains was done and hence we cannot say that the learners benefit from using the tool. Pilot testing of the student performance will be performed based on the pre-test/post-test evaluation, questionnaire and log files. Future goals include expanding the scope of the platform by experimenting with several sensors and several outputs, better electrical modeling, teacher dashboards, server-based saving of information so that progress is saved despite different devices being used, and linking with real boards is not mandatory. What is essential is that classroom experiments will be done to see the results of learning and engagement, and it will help improve the experiments, quizzes, and behavior of the tutor.
