How I Use It
I used code.org during our school's "Hour of Code" day back in December of 2013. I had all students scheduled to visit me in the tech lab everyone created an account. Students worked at their own pace and got as as they could with the multiple levels of the Angry Birds coding game. Many finished all 20 levels within 40 minutes. Code.org was utilized as an introduction to coding.
I really liked Code.org. I especially liked the many options for which game activity you wanted to learn to understand coding. I personally preferred the drag-and-drop coding. Code.org kept the students engaging and they were eager to participate. Many students continued their progress at home because they liked this so much! As a teaching tool, it was nice to start together as a class on the projector and then I let the students take off with it on their own. The only criticism I'd say was that one of my students was able to 'hack' into the website to cheat and get to the end level 20, without actually completing the levels. He told me it wasn't a secure site and that it should be.
