How to evaluate AI educational tools? Without clear, robust guidelines, there is a high risk that AI tools will be used in class, and therefore with children, and for educational purposes, without thorough prior evaluation. This simple scoring guide yields a score out of 40, 30 and a score of 3+ on each question being the minimum "passing" bar. Beyond this, the Guide can also be used to assess different uses of AI tools, and can even serve as a framework for AI use policies. Using such a Guide is not only best practice, but also models how to use AI responsibly with students. In cases of pre / post evaluations, learners can actually be involved in this review process.
