You do realize only a VERY small percentage of dhh kids even GET an oral deaf education right? Even then the problem is that the speech umbrella covers SEVEN of the things you listed. So yes oral deaf educators are CONVINCED that HOH level functioning is THE answer!Yes, it is far more complex than teaching speech. That is why that isn't what we do. We teach receptive and expressive vocabulary, complex language, syntax, pragmatics, audition, speech, academics, social skills, and self-advocacy.
