Lara Cross found Socrative:

• Does not significantly reduce teacher workload“I haven't focused on it as a way to reduce workload”
• Moderately improves teaching efficiency“Depends on what I'm teaching. It does very well at helping diagnose student errors, which can help me be more efficient”
• Significantly improves attainment“Students who regularly practice my course material find that it helps them remember key ideas”
• Significantly builds student knowledge“Again, my subject area (physics) is one that benefits from frequent practice. Students can quickly review a large number of problems, which helps them build their knowledge base.”
