Responding to the first sentence of Professor Wayne Bishop's rejoinder to James Elander: QUOTE > Elander's response represents (one of) the problems > associated with > the New New Math focus on mathematics through > applications rather > than traditional (cookbook if you like) applications > of mathematics > having been developed (lots more of mixed variety are > usually needed >   see Singapore or Saxon) with the emphasis on the > general > applicability of the mathematics having been > presented. UNQUOTE (The whole of Wayne Bishop's post is pasted below my signature, for ready reference).
I do gather that Professor Bishop disapproves of James Elander's approach, but that's about it.
After having struggled with (and having failed to understand) that astounding first sentence quoted above, I decided it would be more profitable for me to try to reread "Finnegan's Wake", by James Joyce, as representing something more readily accessible, and certainly more enjoyable. (I have not tried to read anything beyond that first sentence).
Suggestion: BEFORE we do any math (or criticisms of math approaches), we should try to learn to write clearly and understandably.
