If you're looking to organising a data science curriculum/ hackathon for participants with no prior background in data science, this post might be of interest to you. I have recently concluded a pilot data science hackathon for high school students in Singapore, where students first underwent training for 1 week and subsequently worked on projects with societal impact (listed below). More information regarding the hackathon, training materials and projects can be found here.
This initiative is supported by the KDD Impact Program and the experience was shared at the KDD Workshop on Social Impact.
