Helen Feakes found Twig World:

• Slightly improves attainment
• Significantly builds student knowledge“The keywords highlighted in each film ensure students understand what they are being told.”
• Slightly reduces attainment gap
• Moderately improves teaching efficiency and productivity“I know that almost all topics I teach have an accompanying TWIG video which I often use to introduce/summarise key information. I look on TWIG knowing this so reduce my planning time.”
• Moderately reduces teacher workload“As previous answer - TWIG is reliable and usually has a video I will use in a lesson.”
