The ABCD-ReproNim Course was designed to provide a comprehensive background to data from the ABCD Study® while delivering hands-on, interactive instruction to enable rigorous and reproducible data analyses. ABCD-ReproNim is a collaborative partnership between ABCD investigators and ReproNim.org and is supported by the National Institute of Drug Abuse. Due to the COVID-19 global pandemic, the ABCD-ReproNim Course will be virtual and include both asynchronous and synchronous activities. The 13-week Online Course will include access to pre-recorded video presentations and live Q&A with instructors who are ABCD investigators and reproducibility experts in the field. Readings will be provided for each lesson and data exercises will be posted to help students achieve learning objectives. During the course, students will self-organize into small, collaborative learning groups and develop proposals for data analysis or resource development projects. At the completion of the Online Course, enrolled students will attend a 5-day virtual Project Week, where they will apply the skills they learned towards completion of a project and learn how to contribute to open source software. For more information visit https://ABCD-ReproNim.org.
