2Overview
- Major advances in the learning sciences over past
several decades - Powerful interactive learning environments are
building on these developments - Defining and tackling the challenges of scaleup
and sustainability - How advances in computing and communications are
creating exciting opportunities to address needs - An emerging nexus of technology advances,
learning sciences and educational policy
3Revolutionary advances in sciences of learning
- National Academy of Sciences How People Learn
(1999) - The nature of expertise
- Development of concepts and reasoning abilities
- New pedagogies for deep learning of complex
subjects - Roles of teacher learning
- New assessment approaches for higher standards
- Powerful roles for effective use of technologies
4Aspects of the sciences of learning
- The knowledge-intensive nature of expertise
- Expertise is not simply general abilities nor use
of general strategies - Experts extensive knowledge affects what they
notice and how they organize, represent, and
interpret information in their environments - Expert knowledge organized in large coherent
frameworks - Experts notice features and meaningful
information patterns unnoticed by novices - Expert knowledge reflects contexts of
application--it is not reducible to isolated
facts - Expert knowledge does not guarantee pedagogical
knowledge
5The importance of representational competencies
for expertise
- Expertise often involves the skillful creation,
use, and interpretation of symbolic expressions
(written language, mathematical equations,
graphs, technical diagrams, proofs, computer
programs) - Experts have greater meta-representational
proficiencies than novicesknowing which
representational forms are most suitable for
asking and answering specific kinds of questions - Experts have facile understanding of the mappings
between different representational forms (e.g.,
algebraic functions to graphs or numerical
tables) - Experts are able to assemble arguments, designs,
theories, and other complex artefacts that are
subject to challenge and testing in a community
of peers
6The development of concepts and reasoning
abilities
- Young children rapidly come to make sense of
number, language, and causality - In their efforts to make sense of the world,
children form robust conceptions that may
conflict with the formal knowledge that is later
taught (e.g., intuitive physics) - The development of metacognition is a crucial
aspect of acquiring expertise and becomes a
strategic competency for learning - Knowledge about ones knowledge and its limits
- Control knowledge about thinking and learning
planning, monitoring, and revising ones efforts
7Contextual and cultural influences on learning
- Participation in social practices is a crucial
form of learning outside school and in school - The broad diversity of social practices in
different cultural contexts creates special
challenges for engaging students prior knowledge
in school - Learning is promoted by social norms that value a
search for understanding - Learning is assisted by the family and social
environment in which activities provide
opportunity for learning through participation
8From learning sciences theory to learning
environment design
- Not a simple translation
- Physics constrains but does not dictate bridge
design (Herbert Simon) - The field of the learning sciences is raising
important questions and inquiries - Rethinking what is taught
- Rethinking how it is taught for understanding
- Reframing how learning is appropriately assessed
- Powerful examples of Interactive Learning
Environments (ILEs) that build on our
understandings from the sciences of learning - SimCalcs MathWorlds
- The Knowledge Integration Environment
- WorldWatcher Scientific visualizations for
global investigations - Cognitive tutoring systems
9SimCalc Democratizing access to the Mathematics
of Change
- Enable all students to develop full
understanding and practical skills with the
Mathematics of Change and Variation, including
fundamental concepts of calculus - As early as Grades 5-8against a backdrop of
10 taking High School Calculus, 1.5 taking AP
Calculus - Collaborators
- Jim Kaput (U. Mass, Dartmouth)
- Jeremy Roschelle (SRI International)
- Ricardo Nemirovsky (TERC)
- Rutgers-Newark Syracuse San Diego USI
- How can technologies and engaging learning
activities change the experiential nature of the
Mathematics of Change and Variation by tapping
more deeply into students cognitive, linguistic,
and kinesthetic resources?

11The New Big 3 for Learning the Mathematics of
Change and Variation
12SimCalc Co-evolution of MCV curriculum and
technology
- Curriculum With technology use in activities of
predicting, comparing, designing, build on
student experiences with - physical change (motions, seasons, aging, growth,
flows) - symbolic change (smaller numbers, steeper curves)
- Advanced topics
- Connections between variable rates and
acculumation - Velocity, acceleration, limits
- Contextualizes other mathematical topics such as
- Slope, rate,ratio, proportion
- Areas of geometric figures
13Example of a SimCalc activity
14SimCalc outcomes
- Technology linkages between experiential
phenomena and mathematical representations become
conceptually linked in students mathematical
competencies. - After a three-month supplementary course in MCV
using MathWorlds, students from the most troubled
high school in Newark NJ achieved near-ceiling
effects on assessment items that challenge
university calculus students - Testing low-SES school mainstream Grade 6-10
students indicated higher levels of performance
after MCV coursework than high-SES Gr 11-12
students taught traditional calculus. They. - Relate slope of position graph to speed of a
motion and to the corresponding velocity graph - Infer total distance covered, given by velocity
graph, demonstrating accumulation of area under a
curve
15Now and Future SimCalc
- MathWorlds implementation in Java (Roschelle, SRI
International) - Incorporation of Java MathWorlds in ESCOT project
testbed of interoperable middle school math
components - TERCs LBM (Line Becomes Motion)
- To incorporate kinesthetic experience, students
use mathematical functions created on a computer
to control physical devices (like motorized
toycars) - MathWorlds commercially available in Flash ROM on
TI-83Plus graphing calculators (Fall 99) and PCs
(Key Curriculum Press, Fall 2000) - Massive teacher development with NJ and Mass SSIs
and San Diego USI T-Cubed workshops run by TI
16KIE Knowledge Integration Environment
- To promote coherent knowledge integration in
science learning that is reflectively and
critically used (versus unconnected facts and
beliefs) - Middle to high school sciences
- Marcia Linn, Jim Slotta, et al (UC Berkeley) and
diverse scientist partners and organizations - Expertise involves connected ideas and models
used for reasoning. - Do learners develop more integrated understanding
and models when they engage in meaningful
collaborative projects using technologies that
support key cognitive and social aspects of
scientific inquiry and make thinking visible?
Target Age Who Learning sciences issues
17KIE Technology
- KIE is a client-side front-end to the World-Wide
Web where student project activities are
supported by - SenseMaker software that scaffolds thinking
and the organization of critically-considered
evidence in scientific argument - KIE Project units
- An associated KIE Evidence Database
- Mildred the Cow Guide a provider of reflect
process prompts (what to do next and how) - SpeakEasy net forum for project participants to
share issues - Written reflections and class discussions
18KIE Curriculum
- Student teams work with and/or create scientific
evidence in three kinds of supplementary units (2
days to 2 weeks long) - Theory comparison projects (e.g., dinosaur
extinction, life on Mars) - Design projects (e.g., an energy-efficient home
in the desert using scientific principles) - Critique project (e.g., science tabloid claims on
energy conversion) - Scientist partners (e,g., NASA Ames)
- Post web evidence for pre-college science
teachers - Suggest debates, critiques, or design projects
for learners - Mentor students using personal web pages
19KIE Outcomes
- Students can be effectively encouraged to
integrate their knowledge through simple prompts
for reflection on their ideas (Mildred the Cow) - Students can develop well-formulated scientific
arguments - Net-based discussions enable more students to
voice their ideas about the science, especially
girls - Major improvements in integrated understanding of
project topics such as light, heat, temperature,
and sound
20KIE Now and Future
- Many of KIEs nearly 20 projects have been
classroom-tested - KIE has become WISE (Web-Based Integrated Science
Environment) - and has spawned Project SCOPE
- Science Controversies On-Line Partnerships in
Education - New NSF-funded effort (UC Berkeley, SCIENCE
magazine, U. Washington) - Will develop controversy communities of
scientists and science learners, focusing on
controversies that concern leading research
scientists and also connect to citizen interests,
e.g., - World-wide control of malaria
- Evidence for life on mars
- Deformed frogs (environmental chemical or
parasite?)
21WorldWatcher Scientific visualizations for
global inquiry
- Students at all grade levels and in every domain
of science should have the opportunity to use
scientific inquiry and develop the ability to
think and act in ways associated with inquiry - (National Science Education Standards, National
Research Council, 1996, p. 105) - Using visual reasoning for pattern perception in
inquiries involving complex data sets - CoVis and later WorldWatcher global warming
curriculum as examples - Who Daniel Edelson (Northwestern U), Roy Pea,
Douglas Gordin (now at SRI International) - The multi-agency GLOBE Project coordinated by NSF
provides another example
22A visualization of temperature data for the
Northern Hemisphere displayed by Transform, a
powerful, general-purpose visualization
environment widely used by scientific researchers
23A visualization window from the WorldWatcher
software displaying surface temperature for
January 1987.
24The interface to the library of energy balance
data in the WorldWatcher global warming curriculum
25A tenth grade students hand-drawn visualization
of global temperature for July (Edelson, Gordin,
Pea, J. Learning Sciences, 1999.
26Questions about visualization
- For what domains are visualizations particularly
crucial for promoting understanding? - How does the use of these visualizations
influence mental imagery and reasoning in problem
solving both while using and when without access
to the computer-generated visualizations? - How do how these representations ease the tasks
of understanding and using knowledge about the
conceptual systems they depict? - We need an empirical science of representational
design for understanding complexity, not only
capturing and displaying it.
27Intelligent tutoring environments
- Better and more efficient learning of
well-structured domains algebra I, geometry,
algebra II, college algebra - Middle school to remedial college
- Pittsburgh Advanced Cognitive Tutor Center
(Koedinger, Anderson, Corbett) new NSF research
center (CIRCLE) - Cognitive Tutors conjoin a research base from
cognitive psychology (ACT-R) and artificial
intelligence with curriculum content in
mathematics from math educators - Key tenets of theory
- Learning by doing, not listening or watching
- Production rules represent performance knowledge
- Units are modular, so isolate skills, concepts,
strategies - Units are context-specific, so address when as
well as how - In search of 2-sigma effect where human tutors
excel over classroom instruction by two standard
deviations (Bloom, 1984)
Target Age Who Learning sciences questions
28What cognitive tutors do
- Provide a cognitive model that incorporates
different strategies and typical student
misconceptions - Provide model tracing that follows a student
through their individual approach to a problem
(context-sensitivity) - Uses knowledge tracing to assess student
knowledge growth through graded levels of
competence, and adaptively select activities for
learning (just-in-time assistance in reasoning) - PUMP algebra tutor provides 1 standard deviation
improvement - Results after 3 years of replicated studies of
urban school use in Pittsburgh and Milwaukee
indicate increases of 15-25 on standardized
tests (SAT subtest, Iowa) and 50-100 better on
problem solving and representation use measures. - Students highly motivated, reduce embarrassment,
and succeed - Teachers are able to shift their attention and
support to struggling students
29The view from research to practice
- Too much like Saul Steinbergs famous New Yorker
poster of Manhattan...Everyone knows about the
advances in the learning sciences - Really?
- These advances are too rarely reflected in
educational practices.
30Linear flow model
The usual means of knowledge transfer through
dissemination has rarely worked for bringing
research to bear broadly on practice

32Defining the challenges of scaleup and
sustainability
- Most studies with designs of interactive learning
environments informed by the sciences of learning
are - Small-scale efforts
- Not sustained
- Common problem of lethal mutation of
innovations - Cultural and linguistic diversity of school
environments - Importance of attention to standards,
accountability, assessment at a local level - Teacher professional development
- Marketplace issues from prototypes to
sustainable products and services with needed
support
33Scaling of innovations
- The successes of learning technology innovations
are typically accompanied by researcher hothouse
effects - Common problem of lethal mutation of
innovations (Ann Brown) - Why? Teachers are designers!
- Teachers continue to design curricula in their
classroom uses and local adaptations (four phases
of curricula) - Need to localize for success rarely supported by
teachers understanding of the design rationale
for why the innovation has its features and
practices - Cultural and linguistic diversity of school
environments
34Standards, accountability, assessment
- Curriculum practices are strongly driven by
systems of accountability and assessment - Standards provide an important common language
for expected outcomes - Educators need usable and compelling forms of
assessment in tandem with innovative curricula
and technologies for learning - Performance and portfolio assessments are making
headway as more meaningful guides to progress
35Teacher professional development
- Teacher Professional Development (TPD) is a
critical component of all education reform
efforts - Formal TPD approaches (e.g., summer institutes,
collaboratives) can offer motivating,
collaborative learning experiences but find it
hard to - scale to large numbers
- sustain collaboration back at teachers home
sites - provide cost- and time-effective support through
the change process - tailor content to local school, district
initiatives - build infrastructure for sustainable TPD (and
reform) systems - Difficulties confirmed in evaluation of NSFs SSI
TPD work
36Evaluation of NSFs SSI TPD efforts
- Most states provided limited TPD time and the
SSIs typically supplemented formal TPD activities
with less than 1 week a year - No SSI had resources to reach all teachers
needing TPDonly a minority - Follow-up procedures require many opportunities
for assistance, feedback, and reflection in
coaching, meeting with others involved in the
process or other connections with colleagues - Intros of new practices require time for
discussion, questioning, risk-free practice,
sharing and reflection, revision - Interaction with colleagues very important, since
teachers often work in isolation and lack
opportunities to observe others, share their
expertise and experience, or practice new
techniques. - Good TPD helps build learning communities within,
among, and beyond schools - (Source Corcoran, Shields and Zucker, SRI
International, March 1998)
37The research-commerce culture divide
- Marketplace issues from prototypes to products
and services with necessary support - Two cultures different audiences, purposes,
pressures - The divide may narrow as.
- Research greets complexities of practice
- Grant agencies seek scale and sustainability
- Companies seek innovations and to leverage
external research - New models for public-private partnerships will
need to evolve (beyond technology transfer)
38Tackling the challenges of scaleup and
sustainability
- A design research orientation
- With partnership models that can work in bringing
together necessary expertise and realism to
scaleable learning improvements - With networked improvement communities that seek
to augment collective intelligence for some
purpose and develop sustainable solutions
39A Design Research Focus
- Design research
- Challenges the traditional basic-applied science
distinction - Embraces situational complexity and works to
manage it through to solutions, and reflect them
as cases - Learning engineering Iterative design over
multiple generations of a research-guided
intervention to improve learning
40The need for partnership models
- Tackling design research toward scaleable models
- Brief examples
- SCOPE Science Controversies On-Line
Partnerships in Education (UC Berkeley and
SCIENCE magazine) - LeTUS design circles of middle school science
teachers, curriculum and assessment experts,
learning researchers, technology developers
(Northwestern and Chicago Schools U. Michigan
and Detroit Schools)
41Networked improvement communities
- Communities that seek to augment collective
intelligence for some purpose using the net - ESCOT integration teams
- TAPPED IN and ongoing teacher professional
development - CILT and industry alliance program
- Infrastructure is coming together for schools,
homes
42- ESCOT is a digital library of linkable component
tools and a community of teachers, researchers
developers creating, improving, and testing these
technologies in real classrooms with real
curricula - Principal Investigators Jeremy Roschelle, Roy
Pea, Chris Digiano, Jim Kaput
43Towards a digital library of re-usable components
for middle-school mathematics
- Best of class graphs, tables, calculators,
dynamic geometry, simulations, 100 or so core
elements - Enable plug and play, mix and match
- Linked multiple representations and other core
educational features

- University of Massachusetts, Dartmouth (SimCalc)
44ESCOT Integration Teams put components together
- Teacher Pedagogical Design
- Developer Component Design
- Web facilitator Web Design ( teamwork)
45Its the right time
- Java a common platform
- XML integration glue
- Web coordinate distributed work
- Standards (e.g IMS)
- Labelling for search (metadata)
- Plug play, mix match
- Linked representations
46- Web-based teacher professional development (TPD)

51Some closing observations...
52Underlying dynamics of forces in the
technological landscape
- Moores Law
- Microprocessing capability doubles every year or
at least every 18 months - Metcalfes Law
- The value of a network is the square of the
number of nodes connected to that network
Supply chain efficiencies and virtual companies
are revamping global business and will affect
every life sector (PITAC 98 Report) Fast PCs
and information appliances, fat pipes, digital
content
53Presidents Information Technology Advisory
Committee Report to the President (August 98)
- Vision of Transforming the Way We Learn
- Any individual can participate in on-line
education programs regardless of geographic
location, age, physical limitation, or personal
schedule. Everyone can access repositories of
educational materials, easily recalling past
lessons, updating skills, or selecting from among
different teaching methods in order to discover
the most effective style for that individual.
Educational programs can be customized to each
individuals needs, so that our information
revolution reaches everyone and no one gets left
behind.
54Its not enough of a Grand Challenge
- Enabling this vision requires re-inventing
learning substantively, not only the HOW and WHEN
of learning - We will do better at re-inventing learning if we
heed the PITAC visions of transforming the ways
we - Communicate
- Deal with information (I/O)
- Work
- Design and build things
- Conduct research
- Deal with the environment
- Do commerce
- Each of these areas in society is spawning new
literacies and required skills for an informed
and proficient citizen. - Keeping education apace of the needed learning
curve is the Grand Challenge
55Looking forward, computational media will...
- Because of their use in research and society,
continue to create new content, in mathematics
and science such as complexity theory, neural
nets, emergence - Allow broad accessibility of powerful ideas, and
alter the age level and sequencing of curriculum
we will need to invent to meet the demands of a
new knowledge age - Thus require partnership model research and
development at the edges of content-coming-to-be
collaborative innovations and empirical
investigations of co-evolving subject matter,
technology and appropriate curriculum - Such research by definition will be at the
interstices of the disciplinary areas by which
the National Science Foundation is organized
56Lets work together to rise to this Grand
Challenge for learning and its affiliated
sciences.

58Large research challenges
- Infomating the physical environment for learning
with ubiquitous computing and transmitting
(Spohrers WorldBoard concept extending web URLs
to geo-located things-in-the-world) - Developing Bayesian and other machine learning
approaches to user-profiling of sufficient power
that they may infer a learners interests and
abilities from their net-based interactons, and
offer up relevant resources to learn - Pervasive knowledge integration environments with
rich and age-appropriate metadata cataloging of
web resources for inquiries to develop
high-standards learning - Lifelong digital portfolios of learning
59Facing the challenge
