In other words, one of the great contributions of Hayek was to recognize that equilibrium is what we have here in the text called the positive sense of the term "dovetail coordination." There was no need, in discussing the positive notion of market equilibrium, to use the term "coordination." The term "coordination," while it does have a positive sense, does certainly project the flavor of normative "goodness." But, having so clearly seen and emphasized the positive state of affairs, which we have labeled "dovetail coordination," it is rather obvious that when Hayek referred to "coordination" as a desirable achievement for society, he was referring precisely to that state of correct mutual foresight, upon which the
dovetailing, the interlocking, of decisions depends.
A mix of these two models, couples with the technique of "dovetailing chunks," can result in powerful and flexible instructional systems.
If the above points are attented to when the content and layout of the interactive videodisc are being planned and a "dovetailing chunks" approach is used, then a more flexible and powerful system can be produced.
Given this definition, one might view the "dovetailing chunks" approach as the construction of an array of all the reasonable segments of visual and auditory stimuli that are called for by the courseware design.
But when it comes to joinery, several of the most popular methods, including mortise and tenon, rabbet joints and dovetailing, have come to us straight out of history.
As used in modern times, mortise and tenon, dovetailing, tongue and groove and their many variations meet an important requirement for a strong joint: They present several surfaces where parts can be glued together along the grain.
