As participants are taken to the participate page, they should have a code editor to work with. On the side of the code editor should be instructions explaining the task they are asked to do and how they will complete it and giving them a submit button to signal that they have completed the task. To combine the seeCode.run pastebin and programming studies into a single page, the pastebin can be embedded in a surrounding page using an iFrame.
