Morris Smith found Learning By Questions:

• Moderately reduces teacher workload“Support materials and questions are delivered and marked, allowing quick targeting of intervention and support.”
• Moderately reduces attainment gap“Children's misconceptions are identified early for support. We have used this for intervention groups to enable children to work through a large bank of questions to develop their understanding.”
• Moderately provides school data“Full data breakdown is available for each task.”
• Significantly improves attainment“Children have more variety in the types of multistep problems that they encounter.”
• Significantly builds student knowledge“Children have immediate feedback on questions attempted.”
