I did really like the logic puzzle chat bot. Not so much because it was particularly sophisticated but because of its potential to get students to excited about making something. More often than not, its the teacher or tutor that reaps the greatest learning benefits from an educational interaction. He/she must think of both the content as well as how to teach it which requires a higher level of thinking. In creating a chat bot, student-creators must anticipate what questions will be asked as well as how to create a understandable answer!
Hi @Chris Wong - that was my thinking. I certainly wasn't able to create the next Siri, but was able to create a simple Flow by following basic ChatBot steps (that my students would likely pick up more quickly than I did!). This way, answers aren't simply sitting somewhere on the internet that students can easily search, and they have an incentive to build something challenging yet solvable.
