Having a real teacher in a classroom will always be the better choice for teaching when it is an option. However, if having a real teacher in the classroom is not an option then video lectures are a great alternative. Having some form of teaching is better than having nothing.
Video lectures can help alleviate shortage of good teachers in third-world countries. This will allow it for the same person to teach a ton of people worldwide instead of just a few at their location. This will hel increase the general knowledge of the world and help benefit us all.
I think that video lectures could help alleviate the shortage of good teachers in third-world countries. A video will obviously not take the place of having a real teacher teach in a classroom or one on one attention, but it would provide students a great chance to learn anyway. It would definitely be better than not learning anything at all.
Yes, showing a video lecture of an American professor teaching would allow people in these third world countries to still be able to learn the same amount of material, and let them get a good education. Just give them the same tests and work that the teacher normally gives students.
Video lectures for shortage of teachers in poor countries is a fantastic idea. This is a remedy for the more ignorant parts of the world. Knowledge really is power, and if we all have power, we all succeed as a unit much more frequently. It is still not replacement for an actual teacher.
