Andy Mowforth found Teach Stream:

• Moderately builds student knowledge“Support sessions using Teachstream show students increased understanding following the walk through of questions”
• Slightly improves behaviour or wellbeing
• Significantly improves teaching efficiency and productivity“Running live support sessions on teachstream is easy to setup, students are able to view and comment on what is being shown.”
• Does not significantly reduce teacher workload“It helps run the live interaction session with the students, but there is preparation work required for this so workload not necessarily reduced.”
• Moderately improves school processes
