Donna Whiffen found Koala:

• Significantly increases student collaboration“Autistic student who does not like to turn on his camera is comfortable working through the avatar. He is more engaged than before I used the platform.”
• Significantly improves teaching efficiency“I am able to bring in supplemental material such as videos and PDFs. I am able to create "classrooms" for various subjects and students are able to interact with the material.”
• Significantly improves teacher wellbeing“It's so much fun that it doesn't feel like work. I use the platform 20 hours a week currently.”
• Significantly improves attainment“Without a doubt, the product sells itself.”
• Significantly builds student knowledge“Students are able to learn and be willing participants in the classroom. They are engaged 100 percent of the time because they are interacting constantly with sticky notes, avatars, text boxes, clip arts, videos, etc.”
