This paper explores the significance of interoperability advancements in learning management systems (LMS) and the demand for customizable, flexible learning environments. We present a system that integrates learning resources from an LMS into a highly customizable frontend, including the embedded TaskAssessment, a programming task evaluating software. By incorporating standards such as Learning Tools Interoperability (LTI) and Experience API (xAPI), seamless interoperability across various systems is ensured. The goal is to contribute to the advancement of personalized learning experiences by learning element recommendation, automatic assessment and targeted feedback, while improving system interoperability.
