EUD Strategy in the Education Field for Supporting Teachers in Creating Digital Courses

This paper aims to investigate End-User Development (EUD) strate- gies in the education field. In this area, e-learning is becoming a crucial instrument to promote the role of instructors from simply information transmitters to dynamic co-creators of knowledge among their students. Our idea is to use an e-learning platform to allow teachers to create digital courses in a more effective and time- saving way. This paper proposes a EUD strategy that uses learning objects (LOs) as primary elements. The solution aims to endow the e-learning platform with a smart chatbot to assist teachers in their activities. Defined using RASA technol- ogy, the chatbot asks for information about the course the teacher has to create based on their profile and needs. It suggests the best LOs and how to combine them according to their prerequisites and outcomes. A recommendation system provides suggestions through a machine-learning model to define the semantic similarity between the entered data and the LOs metadata. In addition to suggest- ing how to combine the LOs, the chatbot explains why the module is significant. Finally, the paper presents some preliminary results about tests carried out by teachers in creating their digital courses.
