We are pleased to announce that Alex Konovalov and his colleagues have created a Software Carpentry-style lesson on the computational algebra system GAP. The lesson is at http://alex-konovalov.github.io/gap-lesson/, and the repository for it is at https://github.com/alex-konovalov/gap-lesson. It was taught at a recent workshop, and feedback can be viewed here.
We are now starting to develop a lesson on SageMath. We invite collaborators, please watch the repository if you’re interested in following along, and add a comment to this issue if you’re interested in contributing.
