I can contribute the fact that I taught at community colleges and in literacy-based programs in six provincial and territorial jurisdictions in my career. One of the biggest headaches when you move from one place to another is that your source of materials changes; your curriculum changes. You are delivering math, and math is surely math, but different provinces have different views of it. If you're preparing people to be employable across Canada and to have the kind of mobility promised to us, what we find is that people are trained in certain parts of the country and they do not have the literacy skills to be mobile, and the people trying to teach them do not have access to materials.
Every time I go into a classroom in a different constituency, I have to recreate material or spend a lot of my own time creating materials. I think I'm fairly good at it, but I would surely like to be able to have access to materials that are tried and true, and that is where I have used NALD. I have used NALD in three different jurisdictions now, and I find it just a godsend.
I think there is a distinction between public education systems, which probably end after grade 12, and which have every reason to be provincial in nature, and.... But I also think that once you get past the end of grade 12, you have to look at a pan-Canadian approach.
