All children learn at different levels. Some children need to learn with visual aids, while others need audio. There are other children who need to touch and feel something to learn about it. For example, to dissect a frog, one child may be able to just listen to the teacher, while another child may have to watch a video. Then there is another child who has to see and touch the frog s organs and body parts to learn.
All children learn at different rates.
Some children learn the first time they are told something, while some children have to be told several times. Then there are some children who have to be repeatedly taught and may never understand. Use a computer as an example of how children learn at different rates. You can tell some children how to turn the computer on, what screen to go to and what needs to be done, while some children will have to be shown on an overhead screen. A teacher has to be very patient when it comes to physical and mental learning disabilities.
