In the ever-evolving field of e-learning, Learning Design is a critical success factor as it can support the development of effective and pedagogically informed learning environments. Recognizing the design process as complex and demanding in terms of knowledge, time and experience, this dissertation aimed to explore Recommendation Systems as a means of supporting teachers in the design process. To achieve the purpose of the dissertation, a Learning Design Recommender System called Mentor was designed, implemented and evaluated. Mentor is compatible with the Instructional Management Standards Learning Design Specification (IMS LD) specification, which is the dominant specification for Learning Designs. An important part of Mentor’s design is the incorporation of explanations into it. Mentor has been integrated into LAMS, a well-known system that enables teachers to create, manage and execute Learning Designs. Mentor recommends to teachers Learning Designs based on the reuse of existing ones. Teachers can modify a suggested Learning Design and use it as a starting point for creating their own. Two user-centric studies were performed to evaluate Mentor. The first study was conducted to evaluate the user experience and acceptance of Mentor by its users, as well as the benefits that may arise from its use for the educational community. The purpose of the second study was to explore the potential benefits to the educational community of incorporating explanations into the Learning Design Recommender Systems. The most important contribution of research conducted is that it provides research evidence that Learning Design Recommender Systems is an accepted technology by teachers that support them as Learning Designers when integrated into existing Learning Design environments such as LAMS. ; Στο συνεχώς εξελισσόμενο τομέα της ηλεκτρονικής μάθησης, ο Μαθησιακός Σχεδιασμός αποτελεί κρίσιμο παράγοντα επιτυχίας καθώς μπορεί να υποστηρίξει την ανάπτυξη αποτελεσματικών και παιδαγωγικά ενημερωμένων περιβαλλόντων μάθησης. ...
