Word Problem Canvas and SolveFeedback Application Example 

In this example the user is asked to solve a word problem.  They need to enter all of their steps towards solving the problem, including deducing the initial system of equations.  When the "Check My Work" button is clicked, the SolveFeedback procedure will look through all of the entered math and verify each step, adding a message of "Check This Step" if it thinks something is wrong.

The complete application source code is available here for you to inspect and modify.  It uses the Canvas package to describe the interface, and a ScriptButton to implement an action.
