Help! My Brain is Overloaded!

The UNSW expert in education says we’re being taught the wrong way. The way we’re not taught in the way that’s easier for us to process information. John Sweller says it’s better if teachers give already solved problems so they can study it. He says it’s better because it’s how the brain works. Working memory can only hold 3-4 pieces of new information for only 3-4 seconds without practice and it all goes away in 20 seconds. When learning new information, not everything will be remembered unless you take notes. PowerPoints won’t work if everything written and said is the same. The audience’s attention will be divided.
