The Parallel Curriculum Model can be used for students working at a basic level of skill and understanding, as well as for high-ability students ready for more complex learning options.
I give this book of teaching methods for challenging high ability learners 3 stars because it in fact is full of good ideas. But, oh my, how excruciatingly boring it is to read! Better used as a reference. I would rather read the dictionary!
This was a long, dry read. Definitely would be a better reference or to read as needed. There were parts that were much more helpful than others, but not worth reading outside of direct need.
