FEEDBACK: Postcard to the topic coordinator
This could be a blog or wiki, if the student is using one of these tools throughout the topic for reflection/recording of their progress, or some other tool. However, keep it simple for you as a teacher and the student. Think about the purpose, what you want from this exercise, and what will benefit students. If they are required to learn a tool that has no other purpose and is not useful in any other way (eg in a real-world context) then avoid using it.
