JOY found Koala:

• Significantly increases student collaboration“My students are much more focused! With having the ability to move around their avatar, they can find where I have 'hidden' clip art, they can walk around the rooms where I have posted reading/spelling rules and NOW they can click on them and listen to prerecorded messages from me.”
• Significantly improves teaching efficiency“I am able to 'set up' the room for the next session to meet the needs of the student. It helps me remember all of the rules for that session.”
• Slightly improves teacher wellbeing“I'm not sure I understand this question.”
• Significantly improves attainment“Absolutely. It helps to use more of my students senses which impacts the goal of what they are learning.”
• Significantly builds student knowledge“Same answer. The more my senses and repetition, the greater the impact on my students knowledge.”
