WHAT'S THE TIME? Ninety percent of K-12 schools in the U.S. do not teach computer science, according to Code.org. But by the end of 2013, it wants to switch flip that stat--so that 90% of schools do teach it. The non-profit is aiming to get 10 million students to participate in the "Hour of Code" as part of Computer Science Education Week (CSEdWeek) on December 9-15. Code.org and CSEdWeek will offer one-hour exercises designed to introduce students and teachers to computer science. Participation "kits" packed with tutorials, prep guides, and sample emails to spread the word are available for schools, community organizations and even local officials. Goodies up for grabs include 10GB of free Dropbox storage for every educator who signs up, along with 50 class-sets of laptops for 50 lucky schools, (one in every state). Sign up by November 1 to qualify.
