Feedback during Web-Based Homework: The Role of Hints (Study 2)
This paper reports on two studies. This is Study 2. Click here for Study 1.
The two conditions for this experiment were Tutoring and No Tutoring, both groups received immediate feedback. In the No tutoring condition students were just told if they were correct or not and given the answer in order to go on. In the Tutoring condition the students could ask for up to 4 hints and attempt the problem as many times as they liked.
This image shows how the author of the study put a choose condition and then a post test into the problem set.
This image shows the two conditions in the choose condition. There was a 50/50 chance of being in Tutoring or NoTutoringJustFeedback.
Control - No Tutoring Just Feedback

This is one of the problems in the No Tutoring Just Feedback condition. The student can try as many times as he wants and hence will know if he is right or wrong. If he can't figure out the answer it is given so he can go on to the next item.
