Learning Progressions:
A Discussion

Learning Progressions
 What are they (nature of LP)
 Why we need them (motivation)
 How do we build them
Commonalities
 Progression over larger time units
 Deepening of ideas and level of
sophistication (conceptual framework)
 Change in terms of what kids can do
over time (performances)
 Based on research on student learning
Contrast to standards
 Propositional
 Performance
 Limited research base
 More extensive research
based
 Organization based on big
ideas/practices
 Organization is
problematic, and too many
ideas
 Not conducive to design of
assessments that track
student learning over time.
 Leads to development of
assessments that can
evaluate progression
 Older content
 Strives for cutting edge
Differences
 Motivation- what was the driving force to
develop the progression
 Nature of progression- what does it mean to
move along the progression
 The “stuff” of progressions- what are the big
ideas?
 How do we know what we know? Building
progressions
 Questions that remain
Motivation
 Environmental literacy- informed and active
citizenry
Environmental literacy
Theoretical Framework-Key Practices for Literacy
 (1) Scientific inquiry: developing and evaluating
scientific arguments from evidence,
 (2) Scientific accounts: using scientific accounts of the
material world,
 (3) Application: using scientific accounts as tools to
predict and explain, and
 (4) Citizenship: using scientific reasoning for responsibl
citizenship.
Motivation
 Environmental literacy- informed and
active citizenry
 Students superficial understanding of
current school science content
(standards-based)
Motivation
Students who can write this equation for combustion:
CH4 + 2O2
CO2 + 2H2O
often cannot answer:
"When a house burns to the ground and only
a few pieces of charred wood and ashes are left,
what happens to the rest of the mass of the house?”
(AAAS Project 2061 conference 2001)
Motivation
 Environmental literacy- informed and active
citizenry
 Students superficial understanding of current
school science content (standards-based)
 Integrate cutting edge science into
curriculum; Discrepancy between Atlas
progressions and understandings students
need for nano-scale science (as well as
science education research on student
learning, learning not linear)
Motivation
Based on Benchmarks, AAAS developed a progression of
concepts for several aspects of the ‘Structure of Matter’
Atoms &
Molecules
States of
Matter
Conservatio
n of Matter
Chemical
Reactions
Propertie
s of
Matter
Rather linear and ordered progression
Forces &
Interaction
s
Nature of Progression
 Developing practices of environmental literacyunderstanding and using environmental science to
make decisions at different levels (apply principles
to different systems)
 Progress along model from novice to expertnotions- recognition - formulation- construction -generation
 Making connections- developing web of
interconnected ideas
The “Stuff” of Progressions
 Interdisciplinary- coupled human and natural
systems
 life, physical and earth science ideas
 Tightly woven with inquiry and practices of
responsible citizenship
 From observations to models and theories
 Applying fundamental principles to processes in
systems (carbon and water cycles; systems)
 Democratic participation and reconciling values
and consequences
The “Stuff” of Progressions
Progress variables linked to curriculum
expert
5 Generation: Research
4 Construction: Examining assumptions,
relating models
3 Formulation: Relating ideas and concepts,
simple models
2 Recognition: Language, definitions, symbols
algorithms
novice
1 Notions: Everyday experience, logical
reasoning
The “Stuff” of Progressions

Atomic symbols,

Solid, liquid, gas

An intricate web of
interconnected concepts
How do we know?
 Prior research literature
 Pre-post tests across multiple grades
(traditional instruction)
 Short intervention experiments
 Developing carefully designed assessments
to gauge learning performances
 Tracking individual student progress over
time
 Interviews with individuals of varying levels of
expertise
Common Students Difficulties
 Connecting across levels/
contexts/representations (atom vs. electron
diagram, dry ice vs.. match, hierarchical)
 Reasoning about invisible stuff (ground water)
 Mechanisms and processes (ground water
transport)
 Vernacular interference / leverage (match vs.
fat)
 Model and theory-based reasoning
Questions
 Nature of progression:
 Path/ paths/ landscapes?
 Nature of movement -cycles, multiple states
 Context dependence
 Nature of learning performances:
 Integrate big ideas and practices
 Quantifiable variables that measure learning outcomes
 Nature of evidence:
 Can we really rely on short terms studies, will we (and if
so when) need to actually follow student learning over
grades?
 Wont instruction fundamentally change what students can
do , and therefore the progression
 Challenges for teaching
Questions you had
 What are essential attributes (nature & stuff)
 How do we track student learning (tomorrow)
 Language to describe LPs- What are they
exactly? (what sort of framework)
 Link between LPs and instruction
 LPs impact of teaching and PD
 How does an LP deal with external (prior)
knowledge
