On 23th February, we have explored Khan Academy, which is a non-profit educational website created in 2006 by American educator Salman Khan, a graduate of MIT and Harvard Business School. Khan Academy mission is "providing a high quality education for anyone, anywhere". The website supplies a free online collection of more than 4,000 micro lectures via video tutorials stored on YouTube. There are also exercises to reinforce what you watch from the videos.
The advantages and disadvantages of Khan Academy
- Khan Academy provides a variety of educational objects which include videos, exercises, and data on topics including Math, Science, Economics, Finance, History, and many more. All of these are 12 minutes long and consist of Khan’s voice and sketches on a digital blackboard. Khan Academy has made these videos accessible at all times to all students who wish to learn.
- After watching a video, students are able to complete exercises. These exercises can be broken down step-by-step. After completing an exercise, a student’s coach can view their student’s performance through the use of their data. Completing a certain number of exercises leads to a student’s achievement of badges. After achieving badges, a student can map their progress on a “knowledge map.” A “knowledge map” shows all of the challenges, skills, and concepts they have completed within Khan Academy.
- Khan Academy necessitates the exchange of thousands of skills. A “coach” serves as a model for others who want to learn. In relation to a conventional educational environment, Khan serves as the textbook while the “coach” serves as the teacher. A “coach” fills this role due to their level of involvement.
- Khan Academy does not incorporate a communications network that allows students to discover one another. However, Khan Academy does allow students to inquire about learning activities. Students can inquire about learning activities by searching or by contacting Khan Academy. Most importantly, Khan Academy indirectly includes websites in which students can inquire about learning activities in which they are interested. On these websites coaches may list specified topics they are interested in teaching and students may list specified topics they are interested in learning.
- Teachers become the "coach" to the students on Khan Academy while the students work at their own pace and with other students. The teacher can walk around and monitor how the students are doing and work with the student on a personal level with the knowledge they gained from Khan Academy's Exercise Progress Chart. The Exercise Progress chart shows whether the student is starting an exercise, proficient in it, or failing. The teacher can check how long the students are working, what they are working on, and what videos they are watching on the Activity section of Khan Academy.
Justification
The advantages of the Khan academy far outweigh the disadvantages. Salman Khan’s content and effort, both are commendable and playing a vital role in the propagation of education for all, without any discrimination. Hence, it is important to review all new educational approaches with an open mind while at the same time with a critical eye.
Application
I have used Khan's video for my preparation to teach phase diagram as I have difficulties to deliver this topic which contains of abstract concepts and with lots of explanations. From this video, its helps me to increase my content knowledge as well as gives ideas on how to explain this topic in my lecture class. The phase diagram video is as follows:
