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.
- Evaluate the places where computer mediated
communications can assist learner-teacher and learner-learner
interaction/communication.
- Structure student-instructor electronic interactions to
reduce the burden on the instructor, increase
responsiveness to individual needs. Enhance
the process for all.
- Don't replace the teacher, help the teacher work more
effectively with the heterogeneous body of students. Teacher work is
work with students.
- Provide incentive to create evaluative tools that can raise
student initiative and faculty hope for teaching success. INTERACTION PORTFOLIOS,
electronically formatted and archived essences of
student-instructor interaction, provide the raw material for teachers
to know
their students. With these they can
evaluate their students' progress over time.

- Teacher assumption: Topic, being a regular part of classroom
prior to midterm, then students can handle it from then on their own.
- What is wrong with the teacher assumption: Several steps
needed for independent response to topic
a. Respond to strongly telegraphed prompts – the teacher gives key
words to enhance the significance of the topic.
b. Responds to embedded prompts – the teacher enhances notation to
prompt for the topic.
c. Retrieve from memory without outside prompts – the student finds a
way to recall without teacher-initiated prompts.
- Use student-student interactions as a resource. Help teachers
model their most effective methods so transparently our most successful
students can
use the same resources to help fellow students.
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
- Recognize that encouraging teacher success, without also
encouraging vision, will persuade teachers to limit, rather than
expand,
their teaching concern territory.
- Encourage faculty to document subject matter vision that
encompasses more expertise than one course.
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.
