Launched by brothers Hadi and Ali Partovi, Code.org has raised big money from donors like Bill Gates and Mark Zuckerberg for its unapologetic promotion of computer science education. On the site, readers may participate in the Hour of Code challenge, which teaches basic coding skills to students and adults who have no previous experience. The instructions are simple and easy to follow. Other programs include Play Lab, Flappy Code, and a course of 20 hour-long lessons in ascending order of complexity. For readers who are seeking for ways to introduce students to computer programming - or who want to learn the basics themselves - this site is a welcome resource.
