Re: [Tutor] Recommended Resurce or strategy for beginning students
I like this concept. The only additional information I would add in relation to
any training or educational information. You must include accessibility. As the
laws in many countries require this to be a part of the product. So it is a
perfect time to educate students on this important topic. A high level
awareness is required only.
Introducing the basics. Keyboard navigation, colour contrast, ensuring the GUI
works with a screen reader. The platforms used for GUI should do most of the
heavy lifting.
The other aspect is you need to ensure the course is accessible to possible
disable students for now and the future. If you are based in the Usa. Then
there could be legal requirements for this. Not sure. Out of my scope of focus
in the accessibility world.
A bare minimum is to understand the bare basics which are called POUR.
Reference W3C for the explaination.

Re: [Tutor] Interactive editing of variables.
Mike, thanks for this debug tool. I might have a look at it. No that’s not the goal I’m after. I want to have a basic l input line which is already populated with a value. The value is extracted from a list of strength. Each element in the list are unique. I want to modify the string and then re-insert it back into the same element as the new modified string I’m currently look at read line or piegnurl module this might do the trick. Using GUI is way over the top for the simple thing I’m trying to do The model which Alan kindly suggested if not accessible with a screen reader. As I cannot see e.g. blind, this is a critical component of my programming. Please excuse any errors because I’m using Siri to send this email.
