If/Else - Part 1, Computer Programming
Do it, or else! In conversation, this sounds like an ultimatum, but when writing code, it's a normal way to communicate with a computer. This video shows how to extend our previously used conditional if statement to include the else...

Booleans, Computer Programming
As one accumulates more life experiences, there are fewer and fewer things that are strictly one thing or another. There always seems to be some gray area or middle ground. Not so with Boolean data types! We are in a world of only two...
Khan Academy
Logical Operators, Computer Programming
As the author in this video states, "Life is complex." To handle this complexity, programming languages use something called Boolean operators. In a simple JavaScript code example, this video shows how to set up a conditional statement...
Khan Academy
Function Return Values, Computer Programming
Functions that do calculations usually need to return a value. In this video, a function calculates and returns the total number of donuts eaten based on the years someone has been alive. Hopefully, your charges will have eaten much less...
Khan Academy
Function Parameters, Computer Programming
Learn how functions in coding are even more helpful when you can pass parameters to them. The author shows how to modify a simple JavaScript function to have two parameters that help you position a repeated drawing to the correct place...
Khan Academy
Functions, Computer Programming
The next step in your class's development as young programmers is learning to define and use a simple function in JavaScript code. Younger students may require some additional explanations to help highlight the importance of functions....
Khan Academy
Local and Global Variables, Computer Programming
This video explains the difference between local and global variables in JavaScript programming without getting into the nitty gritty of variable lifetimes. Using a small coding example with a function defined, the author shows how a...
Khan Academy
More Mouse Interaction, Computer Programming
Creating interactive programs can be very exciting for new computer programmers. The author shows how to use mouseIsPressed within a conditional statement to create a small JavaScript program that responds to the user's mouse press.
Khan Academy
If Statements, Computer Programming
This video continues the Khan Academy tutorials and activities on writing code in JavaScript. Here, we are introduced to the conditional if statement. The result is a cute program that produces a bouncing ball. Your young programmers...
Khan Academy
Incrementing shortcuts, Computer Programming
Text messages full of abbreviations can be easier to understand once you know what the letters stand for. The same goes for reading code because computer programmers always devise ways to reduce typing. One typical line of code that...

Terrific Text: Part One, Computer Programming
A program that says, "Hello world," is considered a classic in computer programming. Have your young coders join the ranks of the many others who have created one of these programs. Of course, putting one's flare on a classic is always...
Khan Academy
Terrific Text: Part Two
Start being creative with your JavaScript text. The speaker defines a string and how to combine strings. The program modeled here displays the text, and using the mouseX and mouseY functions, the text grows as it moves. Your beginning...
Khan Academy
More Drawing!
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...
Khan Academy
Intro to Coloring
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,...
Khan Academy
Intro to Variables, Computer Programming
What are variables, and why do I need them? These are the questions answered in this basic computer programming video. The author stresses the importance of how the equal sign used in math class has a different meaning than the equal...
Khan Academy
The Power of the Docs, Intro to JS: Drawing and Animation, Computer Programming
While learning to code is an interesting academic pursuit in its own right, it also has other learning benefits. For one, coders learn how to learn. They continually explore, test, and draw conclusions about how certain things work. The...

Partial Fraction Expansion 1, Partial Fraction Expansion, Precalculus
This is the first of three videos on partial fraction expansion. Sal goes over an example that first needs to be divided so that it is a proper fraction. He then continues to demonstrate the decomposition of fractions. At home or in...
Khan Academy
Plate Tectonics: Evidence of Plate Movement, Cosmology & Astronomy
Need a video to accompany your lecture on plate tectonics? Sal summarizes clues that certain parts of the world may have once been connected. Use the video as part of one lecture or break it up over several lessons.
