Sue Windley found Powtoon:

• Slightly improves attainment“We use powtoon as part of a learning series so not specifically about attainment.”
• Moderately builds student knowledge“Powtoons are great for designing examples for learning activities.”
• Moderately increases student collaboration“Use powtoons to support group learning activities.”
• Slightly improves teaching efficiency and productivity“Not really - time to design a powtoon is way longer than the use of the powtoon!”
• Moderately improves teacher knowledge and skills“Gives ideas on how to explain / express an idea for students.”
• Does not significantly save school money“see earlier answer - lot of time to design the powtoon for 3 minute video!”
