Breda Brookson found Purple Mash:

• Slightly reduces teacher workload“I have to work through each session to make sure I can do the lesson before I teach it. I often don't manage.”
• Slightly increases student collaboration
• Does not significantly improve teaching efficiency“I find it very difficult to follow”
• Does not improve parent engagement“We only use this at school”
• Slightly builds student knowledge“Children are better at at than I am”
