When students make a mistake, they can see that immediately, as the progress bar decreases.ĪIF also pops up encouraging messages, both when students progress, and also when they fail It can even detect progress that's out of order, e.g. On programming assignments, using a hybrid data-driven progress assessment algorithm.Īs students work, AIF monitors their progress, displaying it as a progress bar. The AIF system addresses this in part by breaking the problem down into subgoals that are more manageable than an entire problem.ĪIF also provides students with real-time feedback on their progress What students often fail to realize is that they are making progress,

When a student is stuck, they can request a hint with the click of a button. Research with iSnap used a simpler hint interface, based on the The above demo shows off iSnap's newest hint interface, but much of the earlier If the suggestion is followed, the button or input outline disappears, indicating the student has

If a student requests a next-step hint, iSnap also adds: Hovering over a yellow-highlighted block will show where it can be moved.
