Math Education Game-Changer: Khan Academy Math

- It's Free! [Financially supported by Bill Gates, Google, and others who care about genuine math education.]
- It's available 24 hours a day, every day.
- It's exactly the math that students should learn. There are no constructivist math distractions.
- It
completely covers all important math topics: elementary school
math, middle school math, high school math, and college math.
- Every important math topic is covered with one or more internet videos.
- A typical video is 10 to 15 minutes long. This fits the average child's attention span.
- The student hears the instructor (usually Salman Khan), who is not seen, but appears to be sitting to the left of the student.
- The unseen instructor speaks and writes as he explains the current math topic.
- Salman Khan believes that viewing the instructor's face is an unnecessary distraction for the student.
- Each video is linked to exercises that are designed to test the student's understanding of the video.
- Each exercise comes with multiple hints. After each hint, the student can request another hint, until the problem is completely solved, typically after 3 or 4 hints.
- The student can request exercise after exercise, without ever seeing an exercise repeated.
- The student can easily move back and forth from the video to related exercises.
- There's a "knowledge map" and other orientation features that:
- Show how the current video relates to other videos (including prerequisites for the current video).
- Shows
the student what is possible next, based on what the student has
already done. What is possible next is not limited by the
student's age.
- The Khan system "remembers" what videos the student has viewed and how the student has performed on the exercises.
- Multiple features encourage the student to move beyond initial understanding to full mastery (long-term remembering concepts and methods).
- You don't know what you don't remember.
- There are user interfaces for students, parents, coaches, and teachers.
- It's far superior to classroom learning.
- Each student works at his or hers own pace, at any time and in any place.
- Each student can take all the time needed to master each topic. Unlike classroom learning, there's no need to move on because the teacher is ready to move on.
- Learning is not limited to the content traditionally covered in the "grade" associated with the student's age.
- There's no fear of making a mistake in front of a teacher or peers.
- There's no multiple hours delay between a lesson and "homework." The student can easily switch back and forth from a video to exercises related to the math content covered in the video
- The student can repeat a video, rewind to any earlier point in the video, or fast forward over points already understood.
- The student can easily fill in gaps by using videos that cover content from earlier grades.
- In some ways, it's superior to tutorial learning.
- The student doesn't have to remember what the tutor said.
- The student isn't pressured by a tutor's questions.
- The student isn't distracted by the tutor's face or behavior.
- And it's free!
