I'll only mention the reality that the giving out of Divinty degrees simply encourages mentally blind folks to go forth and spread the poison of disinformation as fact, before going on to address you earlier comment.

                   Schools of Education:

                I can remember sitting down with a "How To" book when I got ready to write my first mystery novel, and discovering on the very first page this statement: Dashiell Hammett was the all time master of the hard boiled detective story.

                This, of course, generated the question: who in the hell was Dashiell Hammett?

                He never showed up in any of my public school text books, he wasn't discussed in any English classes that I knew of. So if he was such an important literary figure, why wouldn't I know about him?

                So I looked into it and discovered: Dashiell Hammett, after having served in both World War I, and World War II, was subsequently jailed and blacklisted by the House UnAmerican Activities Committee in the early 1950's. His material was to be kept from the public, as much as possible, and certainly wouldn't show up in a public text book or discussed in a public classroom.

                Eventually, the government came to it senses and Hammett was buried, as the hero that he was, in Arlington National Cemetary. But he was lost to several generations of American school children.

                I guess my point is, if you are going to fix the system of educating teachers in America, you're going to have to fix something else first.
