I think this is a great tool to get a quick survey from students. It is very user friendly. I like that you can really see your results and where you stand. Also, that it gives you tips on how to improve that area. One thing that I think could improve this survey would be having the freedom to edit it a little bit more. I worry that some students would not handle the results well.
I think this tool could help learners if it were used as a self reflection tool. The students could take the survey at the beginning of their course or school year and then take it again and the end of the course or school year. They can see how much they have grown and how their thought process has changed over the year. I think for teachers it is a good way to learn about your students and understand them more.
