Constructivist Education, Ridiculed by Sport

The comment stream on this post that segued into a discussion of sports coaching reminded me of the original Golf, the Whole Language Way (first seen at Instructivist) and now Balanced Golf Instruction.

I'll give you the first few paragraphs:

Well, folks, here we are at the Supremely Balanced School of Golf. What can the advocates tell us about this method of teaching beginning golfers?

"Our approach to golf development was formerly based upon the wildly successful, but now sadly and unfairly pilloried educational model known as Whole Language. It seems that the right wing fundamentalist fascists have defamed our model so successfully that publishers and speaking circuit organizers are no longer feting those of us who selflessly worked for the social good of the nation. So we've moved on, chameleon-like, and now we have distilled the essence of these in-favour approaches into our old model. We've called it Balanced Instruction because who could criticize such a name? In our publicity blurb we indicate that we have deconstructed the structures and features of golf. (Just between you and me, it was pretty easy to morph the old with the current system - the Whole Language stuff still sits in there - just like a hidden file in a Windows folder.)

We know intuitively that golf is an irreducibly holistic experience best learned by authentic experiences. We enter all our novices in the US Open because that's authentic golf. The teacher's role is that of motivator/facilitator - we empower our students to grow in golf while experiencing a sense of enchantment . We do not teach skills, of course, even though some emerging golfers may naively request help with their swing. We explain that swing is only a sub-skill of golf, and to emphasise it out of the context of authentic golf is time-wasting, or even developmentally inappropriate. Students may choose to practise their invented swing during the Open itself, of course. The principles of the conventional swing are eventually induced by the learner who is highly motivated during an Open, but probably bored to tears and disheartened by artificially timetabled swing practice on a lonely practice range. We know that the swing will evolve naturally, and that feedback is pointless - even damaging to the self-esteem that learners need if they are to take risks with their golf. Admittedly, some teachers initially struggle with this radical non-interventionist aspect.

Because golf is such a natural, holistic pursuit, there is no need to demonstrate grip, stance, or even which end of the club is best to hold. Gradually, through playing in authentic tournaments, the golf game of the novice will more and more closely approximate that of Tiger Woods. If for any reason development is slow, probably caused by earlier misguided attempts at skill instruction, we provide entry into even more golfing majors, such as Augusta, or St Andrews - additional immersion in real golf is the only answer. Golf improvement depends largely on the learner's establishment of a self-regulating and self-improving system, not on anything an instructor might provide.

It goes on. You should read the whole thing. It applies directly to discovery learning of math:

How much success on scores are we having with our balanced, golfer-centred philosophy? Unfortunately that question is very revealing of a failure to keep up with modern conceptions. You are still dominated by out-dated reductionist models of golf. One cannot validly and reliably keep scores without debasing the golfing process. Scores do not reflect all that is entailed by golf - they fail to capture more than the most minuscule element of the whole game.

Barry on guided discovery

from Barry:

"Many of the instructions, and even basic discipline, seem to be a carried out like a full-scale Socratic dialogue with the goal being that the child discovers the all-mysterious point the teacher is trying to make."


Many teachers think that the above is an example of "guided discovery". It isn't. Guided discovery means providing direct information and then asking leading questions based on this information and providing scaffolding as necessary to get students to the next level. Information is given all along, but students are kept actively engaged through questions that 1)allow them to apply the information they have just been given, and 2) to make cognitive leaps to the next level, ala the "spark gap" analogy that Instructivist described some time back. Singapore does this in their textbooks.




I'm going to bug Barry until he writes up an explanation of scaffolding.

I've developed a sense of what scaffolding is in the abstract, but I need more!
