Stacie found night-zookeeper:

• Significantly improves teaching efficiency and productivity“Students have more writing opportunities and practice.”
• Slightly improves behaviour or wellbeing“Maybe if it was used as a incentive when other work has been completed”
• Significantly improves attainment“Students like to see how many words they have written. They also like to see their individual, class, and team rankings. ”
• Moderately increases student collaboration“Making comments on each other's writing. Working together to help make writing better or offering ideas. ”
• Slightly reduces attainment gap“I think it depends. In my classroom it is sometimes an option and some students don't get to it. ”
