Comparing Text to Video to Nothing (9 Conditions)

The purpose of this study is to determine the type of tutoring and how it is delivered is most effective. Text, video, and no hints will be crossed by hints and mistake messages to create 9 conditions. When is video better than text? By "no hints" we mean there is still a button that says "show me the answer" but does not explain anything.

Selent, D, Burnett, A. & Heffernan, N. T. (in preparation) What is the relative learning value of video/text/none for both hints and mistake messages. http://tiny.cc/9Conditions
