khan academy
what is the khan academy ?
Khan Academy is a non-profit educational organization established in 2006 by Salman Khan, a graduate of MIT and Harvard Business School. With the mission of "providing high quality education for all people everywhere", the website provides a collection of free online from around 3200 lectures micro via video tutorials stored on YouTube teaching mathematics, history, finance, physics, biology, chemistry, astronomy, cosmology , computer science, health, organic chemistry, economics, art history, education and American citizenship.
and if you know at this site learning adapted to the age level of the user, so we do not have to worry about answers burdensome because users do not age appropriate
The learning system is enough to listen to or view the video of course sourced from youtube, very simple right?
okay I'll take an example, suppose biology
there you will find two categories: explore or class you can choose one
if you choose a category eksplore then you will find some interesting topics to be discussed
example =Chemistry of life, Studying for the AP Biology exam?, DNA as the genetic material, and etc.
I've seen a video lesson DNA
it turns out that DNA is the most important hl for us because DNA is the earliest we can both recognize something
example is similar to your mother's smile, your face is like your father and it happens because there is the DNA of your parents flowing in your body and etc.
that's my brief explanation about khan academy hopefully sufficiently clear and comprehensible thanks
