As I understand it, currently the pilot participants will vote with these choices:
a. Textbook A definitely, B not
b. Textbook B definitely, A not
c. A, B is ok
d. B, A is ok
d. No pick - use current materials
It would be advantageous from a professional development standpoint to augment the following choices.
a. Textbook A definitely
b. A, B is ok
c. Textbook A or another text that eases teacher professional development
d. Textbook B definitely
e. B, A is ok
f. Textbook B or another text that eases teacher professional development
g. No pick - current materials are adequate or another text that eases teacher professional development
This option set applies to Pre-Algebra (Grade 7 math) in particular. If the other groups (AR-A1-G-A2) pick the same vendor, then it would ease teacher training and workloads by using one supplier for all. It might help the students be more comfortable. Remember that they have different online suppliers for their other textbooks. They have learning curves.
