CRITIQUES OF STANDARDS
Environmental Literacy
Research Group
 Traditionalist critique (e.g., Fordham Foundation,
California standards)
 Too much philosophy, psychology, inquiry
 Not enough rigorous science content
 Science education critique (e.g., us)
 Need to consider changing needs for citizens’
knowledge
 Too many benchmarks: Need to reduce and reorganize
around Big Ideas
 Need to consider advances in educational research
(including learning progressions)
Environmental Literacy

SCIENCE: Interdisciplinary Research on
Coupled Human and Natural Systems

Shift from individual disciplines (ecology,
geology, atmospheric science,
meteorology) to interdisciplinary fields
(environmental science, earth systems
science)

Shift from focus on natural systems to
coupled human and natural systems

Shift from retrospective (reconstructing
the past) to prospective (projecting the
future)
RESPONSIBLE CITIZENSHIP and
ENVIRONMENTAL SCIENCE LITERACY
Environmental Literacy
Research Group
 The world is changing as human impacts on the
environment increase
 Citizens need to consider environmental consequences or
sustainability in concert with other democratic values:
freedom, opportunity, justice
 Actions and decisions in multiple roles that all citizens play:
learners, consumers, voters, workers, volunteers, and
advocates
 Environmental science literacy is the ability to
 Enact personal agency with respect to environmental issues
 Understand and evaluate arguments among experts
 Reconcile actions or policies with values

Environmental Literacy
Research Group
 A research-based learning progression for
environmental literacy topics. This learning
progression will include:
– A review of research on student learning relevant to that topic
– Results of our research on student learning, including what we have
learned from pretests and posttests

series of steps by which elementary, middle, and high school students
can work toward mastery of the learning goals for high school
graduates.
 Assessment tests for K-12 students
METHODS
Environmental Literacy
Research Group
 Data sources
– Volunteer teachers in working groups
– Tests administered to upper elementary, middle, and high school
students (available on website)

1. A 1-gram sample of solid iodine is placed in a tube and
the tube is sealed after all of the air is removed. The
tube and the solid iodine together weigh 27 grams.
Iodine Solid
The tube is then heated until all of the iodine
evaporates and the tube is filled with iodine gas. Will
the weight after heating be:
a. less than 26 grams.
b. 26 grams.
c. between 26 and 27 grams.
d. 27 grams.
e. more than 27 grams.


In physical change, more than half of the
students didn’t conserve the mass of gas.

Even in a closed system, gas is thought to
weigh less than a solid.
BURING WOOD
Environmental Literacy

True or false? When a piece of wood burns, some
of the matter is destroyed.
What is the reason for your answer?
True: 17.5%
False: 82.5%
 “Isn’t there a law that says matter is neither lost nor
created? So I’m thinking it’s just transfer into gas and
ash” (unspecified gas)
 “it is changed to other states/forms such as ash and
smoke” (ashes and smoke)
 “when you’re burning, you’re chemically destroying. So
some matter must be destroyed” (destroys matter)
 “the wood isn’t changing chemically, just physically”



When a gas is involved in a chemical change as a
reactant/product in open systems, added/emitted mass
of gas is ignored
In open systems, students often failed to trace the
pathway of gases and failed to give them chemical
identities
Asserting the law of conservation of mass without
accompanying explanation
Chemical change is not considered as a process of
atomic rearrangement but as a simple change of
matter form
Atomic-molecular reasoning is limited and heavily
context-dependent (e.g. compare to losing weight
question)
LOSING WEIGHT

Some of his fat is gone. What
happened to the mass of the fat?


“It was used for energy” (conversion to

“It was transferred elsewhere and released
from the body, sweat, etc.” (water and waste

“It was burned away, it went away” (simple
subtraction)
“The mass of the fat stayed the same”
(conservation of mass)


The gas products in the chemical reactions of cellular
respiration are not traced; the conservation of mass is
only stated technically.

The context of fat burning gives the idea of energy
production, the process of chemical reactions of
cellular respiration was not traced.

Students knew fat burning is a breaking down of fat,
but didn’t trace it to a chemical process of oxidation
into CO2 and H2O
MATTER TRANSFORMATIONS in
ENVIRONMENTAL SYSTEMS
Environmental Literacy
Research Group
 About half of the students had no commitment to
conservation of mass in changes involving gases
 The other half of the students showed a
commitment to the principle, but were unable to
apply it to more complex chemical changes
 They had problems with understanding systems:
- difficulties in identifying reactants and products
- matter-energy conversions
- inability to use atomic-molecular models

On March 10, 2004, National Public Radio reported that “forests in a remote
part of the Amazon are suddenly growing like teenagers in a growth
spurt.” Scientists have speculated that our actions may have caused
this phenomenon. What do you think could be the scientific basis
behind such a speculation?

been removed or changed to stimulate crop rotation, or even
particles in rainwater or chemical substances.”

KEY FINDINGS
Environmental Literacy
Research Group

Students primarily reason at macroscopic level;
Reasoning at microscopic scale and large scale is
more common in explanations from older
students, but very limited.

Students do not trace matter from organic to
inorganic forms (e.g., decomposition).

Students view living systems as connected by
having things in common or being part of a food
chain, but not by tracing matter and energy.

Students make environmental decisions based on
needs of humans and animals.

COMMON THEMES and IMPLICATIONS
Charles W. Anderson
MICHIGAN STATE UNIVERSITY
PRACTICES 2 and 3: SCIENTIFIC ACCOUNTS
and their APPLICATIONS
 From stories to model-based accounts
– Shift from why to how--purposes to mechanisms
– BUT lack knowledge of critical parts of systems
 From macroscopic to hierarchy of systems
– Increased awareness of atomic-molecular and large-scale systems
– BUT little success in connecting accounts at different levels
 Increasing awareness of constraints on systems
– Increasing awareness of conservation laws
– BUT rarely successful in constraint-based reasoning
 Increasing awareness of “invisible” parts of systems
– Increasing detail and complexity
– BUT gases, decomposers, connections between human and
natural systems remain “invisible”
PRACTICE 4: USING SCIENTIFIC REASONING
for RESPONSIBLE CITIZENSHIP
 Enacting personal agency on environmental issues
– Limited individual agency or responsibility
 Understanding and evaluating arguments among
experts
– Reliance on media and personal experience
– Unidirectional connections between human and
natural systems
– Limited awareness of comparative scale of
