A Stroll Down Memory Lane

Finally, logic gates make some sense. Individuals learn how computers make computations using circuits and logic gates. The third video in a five-part series explains some explains of how different types of logic gates perform different...

If your class has been following the other parts of the Khan Academy JavaScript programming curriculum, they have been using a number of functions already defined in the ProcessingJS library to aid in drawing and animation coding. This...

There is an easier way to share functions among objects. The fifth section of a series of six on object-oriented design introduces the concept of object inheritance. The coding helps pupils create a base object type that has all the...

Programming without color is like watching the Wizard of Oz in black and white, you understand what's going on, but you lose the visual impact of the story. Here, we learn to add color to the images we are coding. Background, fill,...

Now let's expand our coding to include ellipses, rectangles, and lines using this easy-to-follow video. We are also adding some formality to the language we use by defining the following terms: function, parameters, pixels, and the x and...

Draw a rainbow over the rainbow. The second segment in a series of six has the class practice using functions to edit a program that draws a rainbow. After creating the function, the interactive lesson challenges pupils to create another...

This video shows young programers how to use the same concept to duplicate objects with different properties to attach functions to objects. The method allows for functions to be easily called with various objects. 

Text messages full of abbreviations can be difficult to understand until you know what the letters stand for. The same goes for reading code because computer programmers are always coming up with ways to reduce typing. One typical line...

Without getting into the nitty gritty of variable lifetimes, this video explains the difference between local and global variables in JavaScript programming. Using a small coding example with a function defined, the author shows how...

This creative project may make your young programmers hungry as they practice their Java Script coding. The task is fairly open ended: add shapes using different shape functions, including the fill and stroke functions to add color and...
