SideTalk is a back channel application that allows students to post questions in lecture real-time.
The application’s designed for engineering classes at UIUC, where enrollment easily averages over 100 students per class.
The idea of SideTalk is from classmate Sahil Kumar. Alongside code-wiz Isha Dutta, our team developed a mobile interface prototype in CI 482: Social Learning and Multimedia taught by Dr. Mark Dressman. I drafted the storyboard for the application interface and design.
Functionality of SideTalk v3: Stoplights indicate how the students are following along during the lecture.
Red = I’m lost!
Yellow = I sort of understand.
Green = I understand.
The number of red’s, yellow’s, and green’s are tallied for each slide. These numbers are available to the lecturer at the end of each lecture (as part of the day’s dataset). Students are able to view and navigate through PowerPoint slides. Questions 1, 2, 3, and 4 are placeholders for text questions. The chat feature highlights questions from students. The most popular questions appear on top.
