Code.org is one of the most popular coding sites for people of all ages. Its initial training program is advertised as being suited for ages 6-106. The instructional videos are full of famous names like Bill Gates and Mark Zuckerburg. The initial training, dubbed “1 Hour of Code” is a fun little game that introduces students to the basics of coding. It uses drag and drop boxes and familiar characters from games like Angry Birds and Plants Vs Zombies to teach the very first steps that you need to learn. The program doesn’t really take an hour and the instructions are straight forward and easy to understand. Once the 1 Hour of Code is complete, students will move back to pen and paper to learn the basics of computational thinking and the lessons just go on from there. They even offer a K-8 program for U.S. public school teachers that offers up to $1,000 in grant money for teachers who use these lesson plans to teach young children how to code.
Codecademy offers a more straight forward approach to coding lessons. Students complete a short introduction and then are invited to choose between a number of programming languages that the site offers. Currently, users can choose between Java, HTML/CSS, PHP, Python, Ruby, and API. The lessons are broken down into individual components. For example, the HTML/CSS lessons start out by teaching the user how to use the proper tags to open and close an HTML document. The next step from there is learning how to use the tags to create titles, paragraphs and all the other basic components of a website. The lessons are not as colorful or entertaining as those on Code.Org so they would be better suited for high school students. They do, however, manage to deliver a large amount of information in a very short amount of time. The lessons are estimated to take between 10-12 hours to complete.
