"Such a doctrine as the Herbartian, that the mind is a receptacle, lays the stress of education, the preparation of food in enticing morsels, duly ordered, upon the teacher. Children taught on this principle are in danger of receiving much teaching but little knowledge; the teacher's axiom being 'what a child learns matters less than how he learns it.'" ~ (CM Vol 6, page 112. emphasis mine.)
When we write lessons that make all the connections for the child, he does not have to do his own work of connecting. We throw the information and theme at him and it easily slides right out of his head. The theme can be entertaining, at least parts of it. But it's more like a meal that we've pre-chewed for the child and then give it back to him expecting him to swallow it without doing any of the work of chewing and ruminating himself. That analogy is a little gross (sorry!) and doesn't quite work because the child would at least be getting some nourishment even while not chewing his own food. If a child's mind does not have to work to gain knowledge, he will not easily remember or internalize the ideas.
The teacher was probably at her best in getting by sheer force much out of little: she was, in fact, acting a part and the children were entertained as at a show, cinema or other; but of one thing we may be sure, an utter distaste, a loathing, on the part of the children ever after, not only for 'Robinson Crusoe' but for every one of the subjects lugged in to illustrate his adventures. We read elsewhere of an apple affording a text for a hundred lessons, including the making of a ladder, (in paper), to gather the apples; but, alas, the eating of the worn-out apple is not suggested. ~ (CM, Vol 6 page 116)
More learning can take place with less prep work from the teacher if we simply allow the apple to be tasted and appreciated. Exam it when needed ~ there is a place for in-depth study of a text or object ~ but always present the ideas themselves and let the child's mind do the actual work of assimilating. The teacher is there to provide worthy ideas, chiefly by way of good books, answer questions (or put the question back to the child and let him think of possible answers), and prompt discussion and further thought.
