In my role as a Learning Technologist, I have just produced two articles, which discuss student response systems. The articles were compiled from my own knowledge, research and experience (Post 1) and from the ALT discussion forum (Post 2).
The first blog post these looked at the functions of student response systems and what to consider.
The second blog post looked at the systems available (as mentioned by other learning techs on the ALT forum) and their merits.
