Here are some responses to my question, "What is a suggestion that you have to make the activity better?":
"Nothing, it was fantastic."
"Nothing they where perfect!"
"Give us more time"
"Have the instructions in the questions explain what you are supposed to do better."
Below, you will find the results of a survey that students completed to show their interest in the activity and their understanding. They responded on a scale of 1 to 5, where 1 indicates the least and 5 indicates the most.
