"What I liked most is that the tool is very simple. (...) The questions were also very clear and easy to answer. Impact! is very basic and that made it easy to use."
"I liked it that we could give the teacher a tip. With those tips the teacher can do something, he can make his lessons even better."
"The purpose is especially to understand what your students think about the lessons. With that information, you can analyse where you can improve. It actually helps you prepare and design the lessons even better. That's how I see it."
"I'm sure Impact! gives teachers insight into the strengths and weaknesses of their lessons. The feedback is a mirror for me that makes me reflect on my lessons and helps me think about how I can improve my lessons. The tool can be a first step towards improvement."
"The distinction between three student performance groups was useful. When preparing my lessons I use that information, for example: how can I let the most advanced students already work on something valuable? I have used the feedback for that purpose and I noticed that I could pay more attention to the weaker students. I especially payed attention to the performance level of different students when looking at the feedback."
