A Vision for Enhancing the Teacher as a Resource

GOALS

Mathematics is an enormously important skill. Our students can learn to use this skill in one-on-one learner-teacher situations. Technology is the one classroom resource that has increased over the last ten years. We must use that resource to efficiently simulate one-on-one learning situations.
Warning: When I discuss Interaction Portfolios, the emphasis is on student-teacher interaction. It is not a repository, say, for student multi-media projects.

SUBJECT MATTER VISION

Example from Mathematics: Many dedicate their lives to improving first year calculus teaching. Teaching that material, however, by contrast to vector calculus, has an advantage: engineers, physics people, chemistry people, math people, all agree what is its essence. That agreement disappears when you cross into the spatially oriented vector calculus. Especially difficult is how to entwine the necessary algebra and geometry thinking.

The problem: 9th and 10th grade algebra texts have yet to show teachers how put the algebra and geometry modes of thinking together into one classroom. First year Calculus, in a practical sense, is mostly algebra. Failure to deal with algebra and geometry together has meant an almost total wipe out of minority students, for their teachers also stopped with the algebra viewpoint.

Warning: It is nice to think that teachers can apply the materials of their own classroom to outside classrooms. Alas, there is little evidence for this. All teachers would have to grow some, most of them significantly, to use the material they habitually teach in topics from other courses. This holds even in cases where the topics would be almost the same if the vocabulary changed slightly.

Analogy: If you give a left-handed potato pealer to a right-handed person – who knows it is supposed to be a potato pealer – at first they will say it doesn't work right. If you tell them they must use their other hand, you are giving a clue that the change is slight. Switching between the modes of the math and science view of equations and variables can often be compared with switching between right and left-handed potato pealers. If everything is memorized as if the names of variables must be kept intact, you can't switch. If, however, it is understood that mathematics must include all possible variables, and science names its variables significantly, then there is a way to translate between them. Much independent problem solving in math or science depends only on this interchange.
