Speaking to United Review, Norwood described League One as "a battle".
"You have to earn the right to be given a yard of space or any sort of time on the ball," he said.
"It's been a bit of an eye-opener. It's taught me a bit about the ugly side of the game and the importance of going and winning the ball back. I've also learnt that sometimes you have to give your opponent a bit of a kick because he's only going to go and do the same to you a few minutes later.
"It took me a couple of matches to get used to the pace of the game in League One but I feel settled now. Scunthorpe play 4-4-2 with wingers, so I'm in a traditional central midfield role. I'm box-to-box and see plenty of the ball, which suits me."
