Cara found KnowItAll Ninja:

• Moderately reduces teacher workload“I no longer create activity worksheets. I use know it all ninja as worksheets and then create my own extended questions”
• Slightly improves teaching efficiency“It would be great if it could self mark. I do love the revision side of it where i release tasks and students are scored but i wish this would break down even further by providing 'common' questions my students are getting wrong. What they are doing really well in as a group and individually, etc.”
• Moderately improves attainment“I have found that it helps with differentiation. Students have a choice of using my PowerPoints that i go through in class and then using know it all ninja to revise and retain the information gained further.”
• Moderately builds student knowledge“Like my answer above. I feel it gives them more choice in their own learning. They also like the 'competition' aspect of the learning through know it all ninja.”
