Learners can interact with the rectilinear graph to sketch a result based on the function authored on the back-end. ClassPad graphs a function based on the sketch. Learners can fine-tune their graphs by modifying point coordinates before submitting their answer.
Depending on the purpose of the interactive exercise, authors can choose to offer immediate feedback or score results behind the scenes.
Authors have a variety of options to select from to customize the learner experience including tools and toolbar customization, graph dimensions, window and style settings, initial objects, scoring tolerances and custom feedback messages.
