I watched a student follow our inspection worksheet exactly: press request, wait for a blank status box, press it again. The worksheet actually tells them to do that. Our ordinary job request is a short PLC pulse and the application sometimes misses it, so we've apparently taught the workaround instead of describing the handshake. I want the revised lesson and interface to agree. Where would you begin?
I'd withdraw that press-again instruction now. Not replace it with another guess, just stop presenting it as the intended method. Is the supplier aware that's what your students are being taught?
Yes, Nina. I've taken that worksheet out of the session and sent the example to our support contact. Sam, the trace shows a request rising and falling between application reads. It isn't just the student missing a screen change.
I would sketch the displays on paper before asking for new screens. Give someone the pending request and lost-connection examples without the explanation underneath. If both look idle, the new wording has not helped much.
Sam, nobody's asking for a longer pulse here. The lesson needs a response a tutor can explain, including what to do when no answer comes back. Otherwise the next workaround will be somebody's handwritten note.
Toby, blank currently covers all three. Isabel, paper screens sound useful; our tutors can argue over those without waiting for the programmer. The supplier is proposing a held request with a matching acknowledgement rather than a pulse.
That is worth doing. We found a request could remain active while a reopened page looked unused. Fiona, make the restored screen part of the example, not just the first press.
And who answers the tutor's call if it stays waiting? A working explanation needs a person at the other end too. Doesn't have to be the programmer for every question.
The paper exercise was revealing. One tutor read waiting as permission to press again; another thought it meant inspection had started. We've split request pending from job accepted in the proposed display. Thanks Isabel, that caught something our trace couldn't tell us.
Nina, our lab technician is first contact, with the supplier route behind that. Toby and Isabel, page return is on the test list. No revised software back yet, so the old worksheet stays out.
