Although project-based learning is often used with groups of students who collaborate on a project, it can also be a useful approach for learners to use when organizing their own individual learning as Lindsey Ellelfson points out in a piece in Lifehacker. Students can organize their learning as projects by identifying driving questions and issues related to real world problems and then engaging in sustained research to address them. Specifying learning goals in terms of projects can lead to more complete understanding and greater retention.
In our last team meeting, we discussed how learners could do individual rather than group projects. Keeping a social or collaborative aspect is crucial so students can provide peer evaluations or feedback on personal projects. I think this would be an intersting approach.
