• Significantly improves behaviour or wellbeing“Writing scores continue to improve”
• Significantly improves attainment“Using NZK as a tool to measure comprehension of the text that was read while embedding focused vocabulary. ”
• Significantly increases student collaboration“students work together to edit and revise stories that have been written as well as showing their finished product so that others may comment on their work.”
• Significantly reduces attainment gap“Because writing gives a concrete lens into a student's comprehension the teacher can easily look at the a student's strengths and weakness”
