This teacher should go fly a kite
Today, a guest blog by SQE director Frank Gue that speaks to the important role that good textbooks and teaching materials play in good teaching. The teacher in Frank's anecdote was obviously taught by his faculty of education that he was not supposed to be the sage on the stage but rather the guide on the side, and as a result he didn't really need to know what he was talking about but rather just give the students challenging projects and then watch while the students rose to the challenge.
I have a friend whose daughter - call her Jane – is in Grade 12 in a somewhat distant school. Jane's science teacher assigned her to build an airplane to carry an egg without dropping or damaging it. The teacher gave Jane a 12-day deadline.
"Jane asked me for help and sent me her preliminary design. It was, of course, utterly hopeless, although she had used a surprising amount of ingenuity. Since by hand-gliding one of my models she demonstrated a good hand, eye, and instinct for how to hand-launch it (which is a non-trivial skill), I decided I would help rather than discourage her.
"Hmmm. Where to start? There are 300-page books on the subject, such as the one by Perkins and Hage, Airplane Performance, Stability, and Control, and Langweische, Stick and Rudder. One would have to be familiar with most of their contents to meet this challenge.
"Well, having built, over 80 years, any number of aircraft, some of which I designed, I was able to specify for her, straight out of my head and without burdening her with theory, a simple airplane that I know would fly – just the dimensions, wing and tail area, where they should be located, where the egg would have to go, and all that. I gave her this info three days ago.
"I told her also that during the tests (where have I seen that word 'tests' before?) she would crash at least one of her trial designs and would need at least a month of her spare time, which she had better tell her teacher. She should also ask the teacher to make the challenge for a glider, since power and radio add two whole other complex and expensive dimensions miles beyond the scope of a high school project.
"Today Jane told me that the teacher has withdrawn the project 'because the gym is not big enough for an airplane'. This, of course, is a face-saving cop-out: someone has told the teacher how stupid his assignment is. Too bad no one told me how stupid I was to volunteer.
"This teacher lives, not on another planet, but in some other galaxy 100 million light-years from here. People like this teach our kids science and math?! And when Canada’s (poor) innovation record and our everyday existence depend on science and math?!
Discovery learning” (constructivism) rears its ugly head when a teacher, lacking knowledge of some subject, gives an impossible assignment to a student. When the student fails to “discover” the answer, the student has "learned" that he is inadequate and must be stupid. This will add immeasurably to the “stress” among students that is currently being reported in the media.
There are specific cases. Examples include assigning the design and construction of a TV set, or an airplane, or other complex, high-tech product. Such assignments guarantee a student’s failure rather than success. Mastery of a subject must be shown by passing a fair test based on what was taught, not by “discovering” something.
