In a previous blog article, I talked about using Kodables to teach kindergarten students how to computer program — eventually to write JavaScript. The first lesson was based on sequence. Programmers need to tell what computers what to do in the correct order. If one of your computer program statements is not in the right order, the computer program will not produce the correct result. The students learn that by placing directional arrows in the right order so that their Fuzzball (fictional creation) traverses a path and picks up coins. The second lesson is based on conditionals. Conditionals often appear in computer programs as "if" statements. Dynamic Drive example that allows a button to toggle between opening and closing a menu To illustrate the concept to students, they drag and drop a colored square onto the sequence to indicate: if my Fuzzball comes to a square that matches the color, take the action indicated by the directional arrow Here is the first example: Here is the correct solution. You can see that the Fuzzball will move up when it encounters its first yellow square. The Fuzzball will move down when it encounters the second. Though not the shortest path, this maximizes the number of coins collected which is the object of the exercise. Eventually, understanding how checking a condition before taking an action leads students to write correct computer programs. Education is alive in the lab. Go to the original post...
