To get a glimpse of what other teachers from Lethbridge to Edmonton are doing to assess students in Math 20-1,2, and 3 as well as the sorts of questions folks are writing for the upcoming Math 30-1 and 2 diploma exams (it was a great session, well worth attending), see http://learning.arpdc.ab.ca/course/category.php?id=78 . You may need to have attended a CRCPD session to access some of these documents, but you can request permission for each demonstration course and summative assessment examples.
The Edmonton Regional Learning consortium received a grant from Alberta Education to support the implementation of Math 20-2. Several teachers have been seconded. See http://learning.arpdc.ab.ca/course/view.php?id=46 for their work.
Furthermore, the Math 20-1, 2 and 3 learn everywhere courses are now complete at www.learnalberta.ca (click on the “T4T” tab to view). You will need a personal account based on your teacher certification number to view these courses.
Perhaps we should look at what the Alberta Assessment Consortium (http://www.aac.ab.ca/) has to offer. At one point (a decade ago?) Nina was looking at joining the consortium but the cost was fairly high ($3000/year or so) and they seemed to emphasize sorts of assessment we do not use all that much such as portfolios and explorations. Nevertheless, it may be worth another look.
