Codecademy: Hour of Code review and significance

Codecademy has developed a mobile app to deliver a version of the Hour of Code initiative for CSEdWeek. This new development is significant: Codecademy is making its mobile debut! It also is spearheading initiatives introducing young people to code. Furthermore, it puts Codecademy easily accessible on mobile, which is often an on-and-off short interactions (unlike its website presence), and makes it a contender for your time. Competing with games and "less productive tasks", that is. See this useful CNN article for analysis

I was at one time the Codecademy girl, so I can't pass on the opportunity to write about my passion.

Summary review: this app is convenient, meant to be used on the go, zero experience required. It's Codecademy doing what it's best at teaching people to code by making it easy and fun, without the hassle of setting up. Learn coding *concepts* just got a whole lot easier. If you can use an iPhone, you can code.

  • Of course no answer is ever free from Codecademy. Users still have to think and guess a bit. That's the part that Codecademy does the best: remove traditional computer science learning obstacles, but still make the lessons engaging, educational, and gamified with fun.
