Hi Michael,

the best thing I can imagine is what you already plan to do, i.e. cognitive walkthrough. If you stress that the teachers should think aloud and record and carefully analyze their comments, you might be able to distinguish which usage behaviour is for example based on pedagogical knowledge (or prejudice!) about how children learn and which behaviour is based on common ways of thinking in old or young brains. But why not test the application with representatives of the intended user group? Everything else will leave you with many arbitrary assumptions.

Thank you, Detlef.

For sure, I am going to test it with the intended user group - the students. Furthermore, I am also going to test with experts as explained before.

Nevertheless, I also want to know what the teachers think about the app since they have to accept and integrate it into their lessons. So maybe I am just thinking a bit too complicated. I am actually struggling with the task of finding good questions for the teachers and so I asked myself if guidelines and/or templates are available for that.

I haven't thought about conducting a cognitive walkthrough with the teachers yet, because based on the literature a cognitive walkthrough is just for experts. However, maybe the term experts does not necessarily mean usability experts here but also other types of experts as teachers would it be in a pedagogical context.

I would let the teachers have a test run and then interview them afterwards about their pedagogical views. I see no real need for a CW with the teachers. I would include them in the test with children though. They will be of great help in verbalizing issues that the kids cannot identify themselves and they know the children and are expert about children’s behavior. Ideally you’d let the teachers play fist so they know the interface. My2Cents

Thank you for sharing your opinion, Koen Van Turnhout .

Hi Michael,

maybe you should ask the teachers, which exercise could be useful for school students, so you collected user needs. To get feedback, give the students some tasks, that they do in your prototype.

best regards

Hello Michael,

I agree with Detlef and Koen. Perhaps one thing I might add is to perform a pilot study before releasing it the app to all students & teachers. This will help you fine-tune any survey questions you may have or add new ones you hadn't thought of. It will also help identify any user-experience issues the app might have before the hard launch.

Hello Mr Andorfer,

First of all, please forgive my terrible English. I agree with the "teacher" part(sorry if I misunderstand). In my opinion, as for student-oriented application development, the users are always students AND teachers. Personally, I strongly believe that teachers should be the core focus. Education is a very special field, although the users of educational applications are literally students, considering the knowledge and practice level of students, teachers will play an important role in the usage of their programs. And teachers know more about their students, which is helpful for usability testing. In fact, we can find a lot of articles about user testing for children, and I think you can focus on some user testing in AR-games research, which might be useful for younger users.( Pierdicca Roberto,2019,

Thanks for reading, and it would be better if this helps.
