Did it ever occur to you that the level at which this stuff is of any use or even works requires that the student be able to get it from direct instruction? In other words, if you came to me and said "Bob! I successfully turned this student around and they have succeeded in Algebra 1." I would say "Great Clyde. I will fully believe you if they attend that traditional direct Algebra 2 honors course and succeed." If algebra is clicking through their minds then there is no reason that should be a problem.
Why? Because that is how it looks in real life when you use this stuff. You have to be able to fill in a lot of blanks. I have never said that you must start there. I agree that many students suffer by not being ready for that experience. However, you do have to get there at some point to be successful. You can't say "He or she is really getting it, but they still don't get it in a lecture." People are going to ask you "Well, then what do you mean by "really getting it"?"
