Khan Academy's rich repertoire of free courses emphasize videos, practices, feedback, and community questions. These create a highly interactive, personalized, and self-paced learning environment. Courses flow naturally like streams, leading the students through his or her own paths, bends, stepping stones, discoveries, and rewards. Students are motivated with points and badges. Teachers and parents are supported with tutorials, PDF files and real-time activity reports.
We explore the free learning site Khan Academy. First, we focus on student resources, including the areas of:
- Science and economics,
- Computer science,
- Exam preparation.
The "Chops" section explores tools for the "coaches" - parents and teachers.
Dishes - For Students Chops - For Parents and Coaches
This page overviews what students and parents can gain from Khan Academy. An 8-minute video explains how the pre-test helps you find the level to start.
Khan Academy's student-oriented features:
- Practice math and other subjects at your own pace,
- A large library of contents,
- instant statistics for individual student,
- Badges and rewards for students,
- Class reports.
Khan Acadamy contains 4,500 videos (for now), plus challenging practices, documentation in PDF, community questions and answers. Teachers or parents get real-time data - in summary or on individual basis.
You can use Khan Academy without signing up. But creating an account will add tremendously to your learning experience, because most of the pacing, tracking, rewarding features require some minimal personalization. It is easy to sign up through your Facebook or Google account.
All of the site's resources are available to anyone. It doesn't matter if you are a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly alien just trying to get a leg up in earthly biology. Khan Academy's materials and resources are available to you completely free of charge.
A cool tool. This interactive "knowledge map" appears to focus only on math courses. It shows how the math subject is covered, extensively, at every level of skill. Zoom in and link to courses.
The knowledge map shows all of our challenges, skills, and concepts. You can zoom in and out and pan around all the different skills and challenges, just like on a normal map. You can start working anywhere on the map, and the Khan Academy will suggest the best skills for you to work on. We'll even remind you when you need a review.
As you zoom out of the knowledge map, you'll find our challenges, which combine the concepts from multiple smaller skills. Zooming all the way out of t
To access specific math courses, click on "Learn" at the upper left corner. In this example, we then hover over "Math," and select "Trigonometry and precalculus." Next, we select a particular course, "Basic trigonometry," which recently contains 40 video lessons and 12 practices. Khan Academy's math courses are heavily populated with lecture videos using a unique style of digital blackboard with colorful "chalk." Most videos are 3 to 15 minutes long.
In this tutorial, you will learn all the trigonometry that you are likely to remember in ten years (assuming you are a lazy non-curious, non-lifelong learner). But even in that non-ideal world where you forgot everything else, you'll be able to do more than you might expect with the concentrated knowledge you are about to get.
Khan Academy's "Science" section currently contains 9 sub-sections. We have picked a specific biology course, "The tree of life" to showcase its 9 videos, on taxonomy, species, bateria, virus, and human pre-history.
Other than biology, this "Science and economics" section covers the areas of chemistry, organic chemistry, physics, cosmology, finance, capital markets, macroeconomics, microeconomics, and medicine.
Covers topics seen in a first year college or high school biology course.
As an example, this is a direct link to the first video under the economic topic of "Inflation" > Inflation basics > Inflation overview*. After learning from this video, you could watch the next 3 videos, then step back up to view more videos under other topics. Navigate by clicking on the upper left links. Here is a partial outline of this area:
Finance and capital markets (section)
- Inflation (topic)
- Inflation basics (a course/group of 4 videos)
- Inflation overview* (video)
- What is inflation (video)
- Inflation data (video)
- CPI Index (video)
- Inflation scenarios (3 videos)
- Real and nominal return (3 videos)
- Capacity utilization and inflation (6 videos)
- Deflation (4 videos)
Basic understanding of Inflation. $1 went a lot further in 1900 than today (you could probably buy a good meal for the family for $1 back then). Why? And how to we measure how-more-expensive-things-have-gotten (i.e., inflation)?
This section contains a full set of computer science and programming courses, tools, documentation, community questions and answers, and sample programs.
Programming - video and talked-through practices:
- Intro to programming
- Drawing basics
- Animation basics
- Logic and if Statements
- Object-Oriented Design
- Becoming a better programmer
Programming is how we tell computers what we want them to do, like to build iPhone apps, video games, or websites like this one. At Khan Academy, you can use our programming environment to build graphics, animations, and interactive visualizations. If you've never programmed before, follow these tutorials to learn how!
Khan Academy's Humanities section currently contains 3 areas or sub-sections. As an example, if we look into "World history," we will find 5 broad topics, and further sub-topics. This is a partial outline:
- World history (85 videos, 10 practices)
- 1900 - Present: The recent past (46 videos, 9 practices)
- 1700-1900: Enlightenment, industrial revolution (21 vids)
- 1500-1600: Renaissance, reformation (4 vids, 1 practice)
- Before 1300: Ancient and medieval history (8 videos)
- Survey of history* (6 videos)
- Art history (many videos)
- American civics
This Dish links to the third video under "Survey of history*." It is a fast-paced, 9-minute, video lecture that covers the middle of the 20th century, using digital blackboard and photo a montage.
World War II, Hitler, Cold War, Bay of Pigs, Cuban Missile Crisis and the Space Race
Khan Academy contains extensive videos on test preparation for SAT, GMAT, CAHSEE, California Standards Test, and IIT JEE. As an example, this bookmark links to the preparation page for SAT math. The videos are based on an official SAT solution book, identified clearly and recommended in the videos.
Most if not all of Khan Academy's videos are deposited on Youtube, and are thus fast and flexible. Try using the caption feature, even if it is not 100% accurate. Try different color settings, like yellow and magenta.
Sal works through every problem in the first edition of the College Board "Official SAT Study Guide" (ISBN Number: 0-87447-718-2 published in 2004). You should take the practice tests on your own, grade them and then use these videos to understand the problems you didn't get or to review. Have fun! If you're using the second edition of the study guide with 10 practice tests, you can still use some of these videos. Practice tests 4-10 in the newer book correspond to tests 2-8 below.

How do I use Khan Academy to help my child?
This is a course in itself. It guides parents or teachers (coaches) through the process of setting up accounts for themselves and the students. It contains videos, PDF guides, and extensive questions and answers.
Whether you're homeschooling, tutoring a small group of students, or looking for a way to extend your child's learning outside the classroom, Khan Academy can help. See these resources for advice on getting started!
This is a very long page, and apparently an exhaustive list of KA's videos. You can search using the site's search box, or the browser's search function. It looks like math videos account for half of all videos.
