Wondered why in school you always understood better when your teacher explained the same text you read yourself before the class? When your teacher explained it to you, you could see a real person who might be using some props or gestures to make you understand the concept better. There comes a sense of connection and association. For eg; you would have never learned about the dispersion of light experiment had your teacher not explained it to you in person, isn’t it? Exactly this magnitude of understanding is imparted from a video blog or more famously known as the Vlog!!
