Two Cultures? : Let's Make Yoghurt!

Cultivating Science Teachers as Part of the Scientific Community
updated November 14, 2002

Scientist
Science Teacher
Focus on narrow topic

Expose naive children to wide range of topics

Daily attention to same question

Daily changes in information to convey

Continuous revisiting (Re-searching)

Pressing on to new topic to "cover"

Many hours devoted to same work

43 -90 minutes per segment-fixed and frequently interrupted

Chain of command based on experience

One experienced leader w/ 20-40 inexperienced students 3-6 times a day and every year

Seeks questions

Perceives need to have "the answer"

Thrives on mystery

Uncomfortable with mystery

Basics become hidden

Basics must be kept explicit

Experience grows through work in the narrow subject

Experience grows through teaching, classroom management, etc., not subject matter

Experiences teaching "the same thing" year after year get teachers further removed from the minds of their students, who are new every year

Math/analysis performed almost daily

Math/analysis a "unit" in science content

Has helpers (post-docs, students, lab techs) One their own
Has equipment and supplies VERY rare tho some centers provide loaner trunks
Has a telephone, computer, internet access Rarely functions (uses own cell phone for emergencies)

Mythical Thinking from the Teacher's POV

Interested in Teaching? Here's how a teacher describes the features of teaching.

What do science students believe about scientific research?

A scientist is

A good science teacher

Many teachers do not know any scientists.

We (scientists) are experienced in methods of experimentation, they (teachers) are inexperienced in skills and methods of experimentation and theory development. We (scientists) are naive in classroom management and running ALL aspects of a science class. (Teachers rarely have any assistance.) In interactions with teachers, please convey respect, nurture, encourage, break down steps, connect basics to the vanguard research you conduct.

Collegial argumentation intimidates teachers.

Read the NSES and your state and district standards and POS. Ask teachers how they address (they use the term "cover") particular topics. "Think safety" down the road for their naive and inexperienced students. Teachers of science are not stupid.

Volunteer to visit a teacher and help out sometime--especially volunteer to do scut-work like entering grades (allowable if you are not a parent of a child in that school) and/or setting/up/ cleaning up lab materials/stations

Visit with stuff for students to try out --- microfuge tubes, dyes and/or simple chemicals that react with each other, an ice bucket (note I am a biologist). Here are quick links to DNA extractions that's really easy.

Bring Parafilm and let the students stretch out small squares. Even high school students find this to be wild.

Bring micropipettes (old ones that are not radioactive or have been used w/ virus-cultures)

  3. NSF's GK-12 Initiative. Provides support for upper-level undergrads, grad students and post-docs to conduct their research and serve school systems in the classroom or district office.
  4. Bloom's Taxonomy Teachers have been teaching science in the upper (surface) realms; scientists operate in the lower (deeper, higher order, "critical" thinking skills) realms.
