Middle School Computer Science Curriculum

Ellipsis Education provides K-12 computer science curriculum. This lesson represents Ellipsis Education Computer Science Applications courses, made for grades 6-8. Motivate your students with courses that connect to their world. Coding lessons use line based languages JavaScript, HTML, CSS, and Java to explore programming options. Learn more about each Computer Science Applications course below.


Examine fundamental computer science concepts with JavaScript. Integrate conditionals, loops, and arrays in functions to enable user actions on a website. Discuss ethical online behavior and STEM careers.


Use JavaScript and design best practices to solve real-world problems. Expand understanding of concepts including functions, conditionals, and arrays. Discuss collaboration and problem-solving techniques.


Deepen existing computer science skills using Java. Explore loops, objects, methods, and classes to build applications like a fitness tracker. Discuss incorporating feedback and physical security measures.

What is JavaScript?

JavaScript is a programming language that allows you to code interactive content, control multimedia (like videos, photos, etc.), and create animations. It generally makes up the 3rd “layer” of web or app design. JavaScript is a dynamic coding language; it enables a developer to show different things in different circumstances based on the actions of the end user. For example, JavaScript can pull from large data sets to create a custom graph or show directions on a map. On the other hand, HTML and CSS are static coding languages; developers use them to show the same things all the time.

Functions are the backbone of JavaScript programs. Functions use coding core concepts like branching, loops, and variables to create all of the functionality we see on websites.  Functions can house variables, which are flexible storage containers for many different data types. Let’s take a look at some of the most common types:

  1. Numbers: A JavaScript data type that includes whole numbers (integers) and numbers with decimals (doubles).

  2. Strings: A JavaScript data type that includes any characters within quotation marks (“Hello World”, “Fred”).

  3. Arrays: A data structure that stores a collection of values.

The flexibility of JavaScript has fueled its rise to the most widely used browser language today.
