Introduction
Research Questions
How do student's initial graph responses on the web compare and contrast
to paper responses?

What are the effects of feedback and multiple submissions on
student's final responses and submissions patterns?

Motivation

Graphs help students to focus on the first concepts rather than focusing on equations, and graphs are visual, which helps students to learn from them more easily. A web-based system that allows students to draw graph, have appropriate feedback returned to them immediately, and make multiple submissions would be very valuable.
