ASSISTments Case Study
I developed and validated interaction design patterns for an online mathematics tutor with Professor Peter Scupelli. These patterns were used to design more effective and engaging online math problems with the aim of producing positive learning outcomes. The case study is part of a suite of work being published by the National Science Foundation, "Making Math Tutors More Engaging and Effective through Interaction Design Patterns and Educational Data Mining."
"The Terrible Triangle" is an example of a problem that we studied. We selected this problem based on an algorithm that helped us flag problems that many students consistently got incorrect.
For each of the problem, we would consider many different feature relationships to test. We utilized knowledge of the subject, our design expertise, and feedback left by the students to choose which features we tested. Here is an example of the feature relationsips we tested for the Terrible Triangle.
Example of stimuli created based on the features to be tested:
