In Praise of the Book




Alan Wall has written a splendid essay defending the book (and explaining the limitations of Power Point presentations).

"Two examples might point up the absurdity of the 'access rather than internalizing' school of modern learning. Imagine a surgeon who had not memorized his skills, since that was no longer required, but was nevertheless adept at accessing and downloading the necessary information, as and when. One would have to assume that the queue for his operating theatre would soon be dwindling. Imagine a musician, a pianist say, who did not internalize musical skills but once again knew where they could be digitally located and retrieved. How much enthusiasm would there be, I wonder, for his version of the Hammerklavier Sonata?"

"The book represents one of the greatest technological innovations in history, and its fitness for its task, its versatility, its convenience, mean that it will surely continue well into the future. It is also a remarkably democratic technology, in educational terms. If a teacher is giving a power-point presentation, as we teachers are now being exhorted to do, at every available opportunity, then that teacher dictates what is available in the form of knowledge to everyone in the room. She or he presses the keys on the laptop that change whatever text or image is up there on the screen. She decides what I can see and when. But if I am a student and I have a book in front of me, then I can answer back. I can turn my own pages in my own good time, and remind myself of my own marginalia. 'Excuse me, but I don’t agree. What you said about Dorothea in Chapter Five might well be true, but if you’d care to turn to Chapter Nine, I think you might find…'"

I encourage you all to read the entire article which makes some excellent observations on books and electronic media. The author's remarks about PowerPoint are not central to what he has to say in defense of the book.

I agree with Steve that PowerPoint can take less time and be more legible than chalk on a blackboard (or a pen on a whiteboard). That said, speakers often allow, and indeed plan for, their PowerPoint presentation to take over to the detriment of their spoken lecture.

exactly is giving PowerPoint presentations *instead* of assigning books?

The argument here seems to treat PPT as a substitute for something to read rather than as a substitute for writing on the board or using an old-fashioned overhead. In fact, I suspect it's both a substitute for those and a complement to the reading. The best use of PPT is to provide still pictures, video, or audio that makes a reading come to life and deepens it rather than substituting for it. I've seen some terrific PPTs by historians that do precisely this.

And in economics, the ways in which PPT can use motion to make lines on a graph move make it a SUPERIOR technology for teaching, especially at the intro level. A good PPT with motion can show the dynamics of economic processes far better than a book.

For the best example of this, see the marvelous PPTs that Roger Garrison has created, e.g here.

So this whole argument seems to me to be a strawman, absent some evidence that teachers are substituting rather than complementing reading.
