We've had millions of students try the Code.org tutorials. They've submitted over 11 million unique computer programs as solutions to roughly 100 puzzles.
We've mapped out which submissions are errors (ie they don't solve the puzzle), and which are sub-optimal solutions (they solve the puzzle, but not efficiently).
Today, erroneous user submissions receive really unhelpful error feedback, such as "You're using the right blocks, but not in the right way". We want your help improving this, by providing highly personal feedback to very specific student errors. Watch the video below to see what we mean.
Thank you in advance for your help!! :-)
