similar to how we study what professors say.

Language, Identity, and Learning
• Discourse: “a socially accepted association among
ways of using language, of thinking, and of acting that
can be used to identify oneself as a member of a
socially meaningful group” (Gee, J. P. (1991). What is
literacy? In C. Mitchell and K. Weiler (eds.), Rewriting
literacy: Culture and the discourse of the other. New
York: Bergin & Garvey, p. 3)

Some New Ideas
• Environmental science literacy as a way to
address the “depth vs. breadth” problem:
citizenship as a core goal of science education
• Learning progressions as a way to integrate
cognitive and sociocultural insights (but still
more cognitive than sociocultural)
Pinker, S. (2007). The stuff of thought:
Language as a window into human nature
• There is a theory of space and time embedded in
the way we use words. There is a theory of
matter and causality, too. … These conceptions…
add up to a distinctively human model of reality,
which differs in major ways from the objective
understanding of reality eked out by our best
science and logic. Though these ideas are woven
into language, their roots are deeper than
language itself. They lay out the ground rules for
how we understand our surroundings… Pinker,
The Stuff of Thought, page vii.
Contrasts between Force-dynamic and Scientific
Discourse (Pinker, Talmy)
• Force-dynamic discourse: Actors (e.g., animals,
plants, machines) make things happen with the
help of enablers that satisfy their “needs.”
– This is everyone’s “first language” that we have to
master in order to speak grammatical English (or
French, Spanish, Chinese, etc.)
• Scientific discourse: Systems are composed of
enduring entities (e.g., matter, energy) which
change according to laws or principles (e.g.,
conservation laws)
– This is a “second language” that is powerful for
analyzing the material world
• We often have the illusion of communication
because speakers of these languages use the
same words with different meanings (e.g., energy,
carbon, nutrient, etc.)
Daniel Kahneman, Thinking Fast and Slow:
The Psychology of False Certainty
Metaphor of our minds working with a dual
processing system:
• System 1 (thinking fast) instantly and
subconsciously fits what we see and know about
the world into perceptions and narrative
frameworks.
• System 2 (thinking slow) allows us with conscious
effort to question and modify the perceptions
and narratives that System 1 gives to us.
Advantages of System 1
• Enables quick,
decisive action based
on incomplete data
• Enables us to persist
when the odds are
against us
Problems with System 1
• Sometimes wrong
• Is just as certain
when we are wrong
as when we are right
Characteristics of System 1
1. WYSIATI: What You See Is All There Is
2. Substituting an easier question
3. Source amnesia.
4. Confirmation bias
5. Stories, not statistics
6. False certainty
Relationship between System 1 and
System 2
• System 1 always processes first,
producing perceptions and stories that are
sometimes wrong but always subjectively
certain
• System 2 sometimes adds doubts and
reconsider
• Note temporal order: Certainty precedes
doubt
Scientific Inquiry: Reversing the
Temporal Order
Scientific inquiry is a collective process that puts System 2
in charge
• Assume all knowledge claims are initially uncertain
• Study and quantify uncertainty (error bars, inferential
statistics)
• Communicate about uncertainty (e.g., by how sources
are cited)
• Follow strategies to reduce uncertainty
• Giving authority to arguments from evidence rather than
individual people
• Commitment to rigor in research methods
• Collective validation through consensus of scientific
communities (peer review)
• Identifying sources for knowledge claims
Where are we now?
• Science education has never been as
important as it is today.
• We need to mount a national response to an
existential threat: climate change
• Scientific literacy can play a key role in that
response
• We have conceptual tools that we didn’t have
at the start of my career
