This paper presents MADDIs, a Web platform that offers a technological infrastructure to support school Physical Education teachers in using digital educational resources (DERs) related to Physical Education. Teachers can use MADDIs to locate and publish DERs of interest, create and access lesson plans, and collaboratively report their experiences using these resources. DERs available at MADDIs follow the IEEE Standard for Learning Object Metadata (LOM) and are organized in compliance with the Brazilian National Common Curriculum Base (BNCC). The platform contributes to selecting resources useful to the teaching practice, optimizing lesson planning, and fostering the use of digital technology in the teaching and learning process in school Physical Education.
