José Paulo Leal, Ricardo Queirós, Pedro Ferreirinha, and Jakub Swacha. A Roadmap to Convert Educational Web Applications into LTI Tools. In Third International Computer Programming Education Conference (ICPEC 2022). Open Access Series in Informatics (OASIcs), Volume 102, pp. 12:1-12:12, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2022)


This paper proposes a roadmap to integrate existing educational web applications into the ecosystem based on a learning management system. To achieve this integration, applications must support the Learning Tools Interoperability specification in the role of tool provider. The paper starts with an overview of the evolution of this specification, emphasizing the main features of the current stable version. Then, it proposes a set of design goals and milestones to guide the adaptation process. The proposed roadmap was validated with existing applications. This paper reports on the challenges faced to apply it in these concrete cases.
