The biggest problem with teaching reading is that not everyone is ready or interested in learning how to read at the same age. Studying why we can't force a random group of 7 year olds to learn how to read is missing the point. We homeschool. One of my daughters became a fluent reader very early. The other when she was a few years older. You can't force people or children to learn something they're not interested or aren't ready (for various reasons) to learn which unfortunately is basically what the educational system is built around. It's really less about methods which make a marginal difference. The problem with higher education is that we are still forcing people into those programs. If you want to make a good salary you take CS. Whether you have any interest or passion in that area is not relevant. Whatever your level of mathematical maturity is not relevant. You are of the right age and you want a successful career that's where you go. It's no wonder that teaching all those people CS is going to be difficult. It's still the same faulty approach to education. Everything can be taught and everyone can be taught and if it doesn't work we just need to find a better way of force feeding them. Compounding that even further is that teaching is difficult under the best of circumstances. In higher education it's often researchers who are asked to teach (or students) and while they may be brilliant on an intellectual level it doesn't necessarily make them good teachers. EDIT: And a thought on the bi-modality ... I would expect to be able to see this sort of modality at the output of a CS program. I would expect modality amongst students who graduated with the same grades. I would be really surprised if students graduating with the same grades perform similarly in software development tasks. Not clear to me what a CS grade means and how they relate to any natural abilities to e.g. write computer programs.
