Engelmann and Carnine's Theory of Instruction has a reputation for being somewhat inaccessible to many who attempt to read it. It's big, it's long, quite a number of examples are maths related, and lastly (and probably most crucially) they use their own terminology when referring to specific ideas.
Over the past few years in particular, a number of ideas from Cognitive Load Theory have become more widely known and the terminology used has spread further. What I've found from reading Oliver Lovell's book Sweller's Cognitive Load Theory in Action is that a number of the ideas in Theory of Instruction relate back to the ideas in Cognitive Load Theory. That creates an opportunity, where the ideas in Theory of Instruction can be linked to ideas in Cognitive Load Theory to create a more widely shared vocabulary. Below I've used quotes from Ollie's book to compare Cognitive Load Theory with Engelmann and Carnine's Theory of Instruction.
