Use this scrum review template (in Library > Learning Resources) to list out each scrum, the action the referee should do, what the players are doing, what talk from the ref is required and a description of context.
To use as a development tool - watch one of your own games. What you choose at home on paper, might not be what you did on the day - but this is how you can implant better actions and outcomes in your mind, ready for the next game. Even if you don't have videos of your own game, use this as a learning tool by watching any other game!
Of course, this template is already filled in - use it (and the videos linked) as a guide but make a copy, empty it out, and try it with your own.
