KM: In the beginning......

In 1956, little Dick and Jane sit in their classroom, listening intently to their teacher as she describes some of the ancient world explorers’ voyages around the world. Then she raises the blinds that are hiding the classroom blackboards, filled with writing. The class is instructed to copy the paragraphs of text, which re-iterate what the teacher has just been talking about, into their notebooks. At the end of class, an outline map of the world is distributed to each student and they are given a small homework project: to create a map that shows the explorers’ voyages around the world.

Now, the notebook used in primary school measured 7” x 9” and contained about 20-24 wide-ruled pages. Every line was to be filled with text (block print or script) before a student could request a new notebook. The teacher was in control of allocating new notebooks; to safeguard against the wasteful practices of students, the teacher would inspect each notebook to ensure that as much whitespace as possible had been obliterated.

Late that afternoon after school, Dick and Jane sit down to complete their homework.

Dick, being a TV stereotypical boy of the time, picks up his pencil and quickly draws crude lines to indicate the explorers’ voyages. But the map is confusing: all the lines are the same, some lines are too close together and sometimes cross over each other. After a few attempts and crumpled drafts, Dick finally produces a map. To distinguish each trip, he uses solid, dashed, and dotted lines, and indicates the explorer’s name and the year of each voyage on the map. The map is black and white; if Dick is sufficiently interested in this exercise, he might colour his lines. But Dick doesn’t waste too much time on this work, as more important projects wait: baseball if it’s not too late, comic books, and later some TV before bed.

Jane, being the TV stereotypical girl, gathers her colouring pencils and begins to turn her outline map into a collage of colour. Then she selects a particular colour to represent each explorer and draws the path of each voyage. She, too, uses solid, dashed and dotted lines to indicate the different voyages of each explorer. Like Dick, she had other interests; however, she had a greater desire to please the teacher and took a little more time and care in preparing her map.

Dick and Jane have both just experienced the making of a knowledge map, although it was never explained to them what it was that they had just created or how they could build upon this map to retain the knowledge they had learned.
