I was teaching a high school computer course when I discovered Codecademy in 2012. We spent three weeks using their introduction to JavaScript programming. Students learned basic programming working at their own pace. Everyone was engaged, and most students enjoyed this part of the course. I worked all over the room, answering questions and seeing how students were doing. The site kept track of progress with game-like points and badges. The last week of the semester, students created two interactive web pages using what they'd learned. These two projects were similar to programming labs I had done in past years, but the instructions were much shorter because Codecademy prepared them much better; and the results were better because students were more competent and felt more confident from their Codecademy work. In subsequent years I continued to use Codecademy for JavaScript and added HTML instruction around 2014 based on their site too. Overall I think hundreds of students benefited. Many thanks.
