>A good teacher is able to [...] Why not just let the teacher teach [...]? By adding a qualifier such as "good" as in "good teacher", you've (inadvertently?) made your argument look more reasonable and correct. Some teachers are good, most are average, and many are bad. The gp you responded to is talking about superior teaching recordings to help the teachers at bad schools. (But it can also help the good teachers by letting them put more energy into the 1-on-1 phase of instruction.)
