Attached is a document I created to try to assist in teaching sighted Nemeth students to get a better feel for making code switch decisions. There are verbal explanations that would accompany this. Does it look to you as if this document is accurate as far as it goes? Teaching Nemeth is easy, but working with the code switching has been painful.
Thank you for tapping this Ask an Expert resource to ask about your training materials. Overall, your examples are correct. I have attached a DOCX file that includes slightly different highlighting than yours as well as commentary (accessed under the Review tab in WORD).
You may consider including an example item (let's call it item #99) that is all Nemeth material and occurs following an item that ends in UEB and another item that begins with Nemeth material. In such an example item, the opening Nemeth Code indicator would best be placed following the item identifier (99.), and Nemeth mode would be left in effect through the end of item #99 and through item identifier 100. This could serve to reinforce your well-stated point that in linear math, nothing gets between an item identifier and its margin.
Thank you for the comments. I removed the initial highlighting from the commas. I've added a new problem in the second example which I think makes the point you are referring to -- the flow of Nemeth from problem 5 into 6? (I'm hoping the file I'm attaching has the changes I made. It's showing an earlier time stamp no matter how many times I save...)
I am still undecided about the use of two highlighting colors. I understand your distinction, but I am concerned some of the early Nemeth learners will think the second color means some other kind of indicator, which it doesn't always mean. I might show it both ways to students next week to see how they react.
