Using videos in learning and teaching is very good and effective as learners understands and remembers better what they see than what they read,hear or copy from the board. The primary teacher who always tells story and uses charts to convey the message is the one the learners undestands better.
All the videos are very useful to me as each have the special way of conveying the message. Skinner's explanation on Behaviorism is the easy to be remembered as he uses different kinds of animals and Piaget mostly uses kinds to explain his theory,I really enjoyed the videos and learned a lot from them.
I also think using technology in teaching and learning is best as learners can watch pictures of what they are learning and play games not to be bored.
