Michael found FilmDoo:

• Moderately builds student knowledge“I've seen my students retain the information for longer, especially if they've done repeat viewings.”
• Significantly increases student collaboration“It's a part of the class that my students look forward to which brings out their competitive natures and makes them really focussed.”
• Moderately improves teaching efficiency and productivity“The tool is very easy to use. I've created classes that I've re-used for multiple new students, which has saved me a lot of time in my lesson prep.”
• Moderately reduces teacher workload“I've found it helps me to find out where the knowledge gaps are and address them. Saving me time in trying to figure out where they are with my students.”
• Slightly saves school money“Not known”
