From December 7 to December 13, in celebration of Computer Science Education Week, millions of students throughout the world learned the basics of computer science. The Hour of Code is designed to inspire students of all backgrounds to consider a career in software engineering. Students learned the basic concepts of computer science using Blockly, a drag-and-drop programming tool, to generate executable code. Blockly is used to teach programming concepts such as loops and conditionals.At AE/MS, all students in grades one through eight had the opportunity to code using themes of Star Wars, Minecraft, Plants vs Zombies, and Angry Birds. (In this photo, Dannicka Dlubac and Al Dudek take a quick break.) Students may explore more at Code.org, a Seattle-based non-profit dedicated to giving every student in every school the opportunity to learn computer science and expanding participation by girls and students of color.
