Title: Learning Progressions:
1Learning Progressions Some Thoughts About What
we do With and About Them Jim Pellegrino Universi
ty of Illinois at Chicago
2Why Learning Progressions?
- Learning is facilitated when new and existing
knowledge is structured around big ideas or a
conceptual framework rather than small, discrete
bits of information. -
- Learning develops as a continuous process with an
individual continuously making links back and
forth among ideas and not in linear, discrete
steps. - Learning difficult ideas takes time and often
comes together as students work on a task that
forces them to synthesize ideas. - Yet, K 12 science curricula are generally not
structured to build and cycle back on ideas.

5Assessment as a Process of Reasoning from Evidence
- cognition
- model of how students represent knowledge
develop competence in the domain - observations
- tasks or situations that allow one to observe
students performance - interpretation
- method for making sense of the data

Must be coordinated!
6Guiding Principles
- All models are wrong, some are useful
- George Box
- Better an approximate answer to the right
question than an accurate answer to the wrong
question - John Tukey
7Assessment Design Principles
- Assessment design should always be based upon a
model of student learning and a clear sense of
the inferences about student competence that are
desired for the particular context of use. - The model of student learning suggests the most
important aspects of comptence that one would
want to make inferences about and provides clues
about the types of tasks that will elicit
evidence to support those inferences.
8Aspects of Student Models
- Domain specific and empirically based
- Identifies cognitive performances that
differentiate expert and novice learners - Lays out one or more typical progressions toward
competence including milestones or landmark
performances along the way. - Can be at various levels of detail grain size
depends on assessment purpose

11Interpretation -- Making Sense of the
Observational Data
- Some of the ways in which individuals typically
try to make sense of the observational data - Intuition -- gut reaction
- Counting number correct (4/8) generating percent
correct - Assigning points to answers or assigning letter
grades - Going deeper -- getting at student strengths
weaknesses - Focus on the nature of student thinking,
including misunderstandings, not just correct
responses - Create interpretive scales and rubrics that
provide detail about multiple features of student
competence - Assessment isnt just about assigning scores
- Its a meaning making process
12Learning Progressions
- Description of successively more sophisticated
ways of thinking about a big idea - Provide a framework for long-term development
- Describes what it means to move towards more
expert understanding in an area - Gauge increasing competence over time
- A sequence of successively more complex ways of
thinking about how an idea develops over time - Consider how ideas build upon each other to form
more complex practices or ideas
13The Researchers Modelof Development/Change/Progr
ess
- A central feature of all this work resides in the
researchers beliefs about the nature of
individual development or change -- IN ONE OR
MORE DOMAINS!!!! - These beliefs affect the researchers choice of
theoretical framing, choice of data, choice of
measure, and choice of analysis tools - Choices interact with each other affecting the
way claims are warranted and inferences are drawn
14Questions to Help Unpack Likely Assumptions
- Question 1
- Has change been framed as systematic or random?
- All assessments have error. How does your model
of change adjust for this error, or does it?
15Questions to Help Unpack Likely Assumptions
- Question 2 Is development reversible?
- Implications for the form of the measurement
- Implications for the functional form of the
developmental trajectories - The shape of the trajectory should be
hypothesized before data collection - The shape can be empirically tested
16Questions to Help Unpack Likely Assumptions
- Question 3 Is the change unitary or multi-path?
- Your theory of learning should be able to
identify and describe why certain groups of
students follow different growth trajectories
17Questions to Help Unpack Likely Assumptions
- Question 4 Can we consider change to
- be a continuous, gradual, quantitative
phenomenon? - have large magnitude shifts on a quantitative
variable? - Be a progression through as series of
qualitatively distinct stages?
18Questions to Help Unpack Likely Assumptions
- Question 5 Is change considered as differences
in magnitude in - an absolute sense?
- calibration?
- conceptualization?
19Questions to Help Unpack Likely Assumptions
- Questions 6 Is change considered a shared
characteristic of a group of individuals over
time? - Is it what occurs within individuals over time?
- Or both?
- Keep in mind that both kinds of change can occur
simultaneously!
20Questions to Help Unpack Likely Assumptions
- Question 7 If we assume that all individuals
have trajectories of the same functional form are
there systematic inter-individual differences in
the values of the individual growth parameters? - What would this mean theoretically?
21Questions to Help Unpack Likely Assumptions
- Question 8 Are there cross domain relationships
in change over time? - Is the relationship between inter-individual
differences in intra-individual change over time
(and the predictors of those differences)
invariant across learning domains?
22Questions to Help Unpack Likely Assumptions
- Question 9 Finally, is there invariance across
groups with respect to the facet of change over
time under investigation? - Put simply, are change patterns at the group
level constant or invariant across groups?
23Ravits 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 (instructional practice)
- Challenges for assessment
- Challenges for curriculum design
