How I Use It
Studio.code.org ain't no hour of code! This really digs into the concepts of coding.
First, you need to make sure you know how this stuff works. Depending on you, that might take some time or be a breeze. Ideally you would work through the whole curriculum.
I then walk my students through elements of it and have them work independently. Like you and I, some of them will breeze through and some will struggle. I usually try to team students up into similar interest/ability levels so that they can really help each other through problems. My role is to support them as they work through those challenges, ideally asking the right questions instead of giving answers.
Please note that I am specifically talking about Code Studio (a feature of code.org that they are not continuing to develop). studio.code.org is probably the best thing I have found to teach principles of coding. You're working with real code but, if you're working only in block mode, you don't have to worry about syntax. Nevertheless, you are working with real code, real design principles, and looking at real results. The best part of it is that it actually includes REAL APPLICATION of the code you are learning.
It's very challenging at times, and some students will definitely need your support. You will need to understand principles if you are going to support students adequately.
