Mark Dunn found Eedi:

• Does not save school money“Hard to use for tutoring just one or two students.”
• Does not significantly reduce teacher workload“Taking too long to find relevant material. Not supporting free text prior to multiple choice prompts. This could be a powerful technique for many (NOT ALL) diagnostic questions. It could provide much more insight into misconceptions. Especially if combined with students giving a level of confidence in their answer (RAG, say). A confidently wrong answer needs a different response to a low confidence right or wrong answer.”
• Does not significantly improve teaching efficiency“When tutoring and using Diagnostic Questions with the student, there is more chance to discuss the options first. Eedi doesn't really support this. This is another way that free text input on suitable question structures would be valuable prior to offering multiple choice answers.”
• Does not significantly improve attainment“Having not used it because it didn't fit my work style well, I cannot give any real concrete examples.”
• Does not significantly build student knowledge“Have not used it to really say. I found it useful to experiment with, but it was frustrating.”
