Second Advanced International Colloquium on
Building the Scientific Mind (BtSM2007)
Vancouver,
Canada, May 28-31, 2007
The common thread that connects
the members of the problem-oriented learning group is shared
interest, experience, and insight into inquiry, problems, and/or
problem solving as mechanisms for learning or as outcomes of
learning. For the purpose of BtSM 2007, we will be applying this
shared interest to a specific theme, i.e. developing and nurturing
the scientific mind. A short description at http://www.learndev.org/PBL.html
gives some insight into some aspects of what we might consider
under the PoL umbrella.

Paul Horwitz is a Senior Scientist
and directs the Modeling Center at the Concord Consortium in
Concord, Massachusetts. He is a physicist with broad interests
in the application of technology to science and mathematics education.
In 1984, he was Principal Investigator on the ThinkerTools Project,
sponsored by the National Science Foundation, which designed
a curriculum and associated software that successfully taught
the elements of Newtonian physics to students at the sixth grade
level. In 1992, a simulated "Relativity Laboratory"
that he designed won two EDUCOM Higher Education Software Awards,
one for Best Natural Science Software (Physics), the other for
Best Design. He recently served as Principal Investigator for
the Modeling Across the Curriculum Project, sponsored by the
IERI Program at NSF. This project examined the use of "hypermodels"
- computer-based applications that scaffold students' investigations
of a manipulable model - to teach high school students about
models in physical science, biology, and chemistry. The hypermodels
posed problems to students, then monitored and logged their actions
as they attempted to solve the problems. This fine-grained performance
data was used to demonstrate student learning and shown to correlate
to scores on traditional question-and-answer tests.

All nine PoL group members were
asked to generate a couple of questions that could serve
as a source of inspiration not only for their own contribution
to the dialogue but that could equally inspire their colleagues.
They were also asked to provide a brief rationale for their questions.
Below is the tabulated result of this initial exercise, presenting
the questions in the order in which they came in.

Question
Underlying thoughts
01
Michael Hannafin
To what extent are presumed discipline-specific
knowledge conventions and standards unique?
Differences are apparent among disciplines
in how knowledge and truth are viewed, validated and accepted.
Similarly, disciplines espouse different ways of knowing.
In many cases, these differences exist within specific fields
of study. History as a discipline documents events, but historical
accounts and interpretations can vary widely from historian to
historian and culture to culture. Within the hard sciences, some
associate the accumulated knowledge synonymously with the discipline,
while others view formal scientific knowledge as transitional
state of understanding that is continually modified as discoveries
challenge current assumptions or is transformed when new discoveries
cannot be reconciled within existing research or theoretical
frameworks. Thus, many emphasize how something is understood
(ways of knowing) and characterize the discipline more in terms
of inquiry than formal scientific knowledge, per se.
02
Michael Hannafin
How do disciplines determine whether
(and which) knowledge and practices are valued, thus establish
unique and peculiar discipline-specific standards and conventions?
The knowledge base and practices
of different disciplines emerge and evolve in very different
ways ranging from progressive refinements resulting from highly
disciplined inquiry to evolved craft and lore. Where the
emergence of a knowledge base depends on disciplined inquiry,
rigorous scientific study is the gold standard; evidence either
generated through such study (or framed accordingly) tends to
be valued and influences practice. Likewise, while soft social
sciences researchers also generate knowledge via disciplined
inquiry, practices may be influenced more by intuition, craft
and perception. So, links between formal knowledge and practice
can have a very profound influence on both what constitutes a
discipline and the forces that shape its evolution.
03
Michael Hannafin
How do we facilitate the efforts
of individuals and communities outside a given discipline to
know and understand those standards and conventions that are
unique?
How we recognize and understand
(or fail to do so) different disciplines has a profound influence
on our ability to learn from and support them. To those already
immersed in the study of a given discipline, the values, conventions
and standards may be largely tacitembedded within and integral
to how it is learned and understood; the unique and peculiar
aspects of that discipline may not be apparent. To outsiders,
those same aspects may contradict beliefs and practices derived
from study in a different discipline (or different conventions
and values within the same area of study). It is important,
therefore, to recognize how ones individual mental traditions
influence (perhaps confound) how understand and interpret the
knowledge and practices of other disciplines and fields. Whereas
traditional efforts have emphasized formal knowledge, perhaps
it is more important to understand how formal knowledge emerges
and becomes reified in the practices of different disciplines.
04
David E. Kanter
Can we design instruction for use
in schools that supports teaching content in such a way that
the learner is optimally prepared to use this content later to
solve novel problems?
It is not trivial to design project-based
curricula that support students building a meaningful understanding
of the underlying content while completing the task around which
the curriculum is based. Many curricula fail in their design
to support simultaneously both the project doing and the content
learning. Care is required for the curriculum designer
to notice the curriculum design challenges that emerge from this
tension between doing and learning; care is required on the part
of the curriculum designer to apply various design approaches
to resolve this tension. However, even well-designed curricula
can be misunderstood by the teacher and as such used differently
than intended. While care is required to design curricula
that do a better job of communicating to the teacher the strategic
function of each lesson, this must be met by a useable body of
content knowledge and pedagogical content knowledge on the part
of the teacher. Curriculum-driven practice-based models
of professional development may help teachers bolster their knowledge
in such a way that they are more facile teaching with project-based
curricula to get students to a meaningful understanding of the
underlying content.
05
David E. Kanter
Do such curricula require that students
learn the content for problem solving in the context of actually
solving problems?
06
David E. Kanter
If so, how do we best design such
curricula to work in today's real classrooms? Secondly,
what does a teacher need to know to effectively teach such curricula.
Lastly, how do we best develop this body of knowledge in teachers?
07
Yusra Laila Visser
What aspects of the scientific mind cannot
be developed through problem-oriented teaching and learning approaches?
Formal education settings have often
been challenged in providing the conditions that might yield
complex and sustained change in the form of the development of
dispositions. Indeed, the formal education system tends to be
focused on providing the conditions for teaching and assessment
of objectively-measurable performance in discrete disciplinary
areas. Since many problem-oriented learning strategies, such
as problem- and project-based learning are designed for implementation
in the formal education context, it appears relevant to identify
not only how such instructional strategies can be effective in
supporting the development of the scientific mind, but also where
they might fail.
08
Yusra Laila Visser
How could the conceptualization,
design and implementation of problem-oriented learning (PoL)
be reconceived in order to support the development of those attributes
of the scientific mind that are currently not developed through
PoL?
This question assumes that there
is indeed a case to be made for the hypothesis that problem-oriented
learning in its current incarnation(s) is not wholly effective
or adequate for building the scientific mind. The question is
also posited from the vantage point that the mere identification
of limitations to a given educational approach should not result
in the abandonement of the approach. If, then, there are aspects
of the scientifc mind that cannot be reliably nurtured or developed
in the context of the current incarnation of problem-oriented
learning approaches, how can PoL approaches be reconceived to
increase their impact on the development of the scientific disposition?
09
Yusra Laila Visser
How can our current conceptualization
of problem-oriented learning approaches be used to develop problem-centered
instructional approaches that can be sustainably and effectively
implemented in the developing country context?
Problem-oriented instructional strategies
have had quite some traction in formal education systems in the
developed world. Developing countries, however, are plagued with
challenges that make the implementation of "our" problem-oriented
learning approaches highly unlikely at this time: inability to
meet even basic education needs, lack of formal training of teachers,
high mortality rates among teachers as a consequence of HIV/AIDS,
lack of funding for education, etc. Yet it seems that the infusion
of problem-oriented learning into formal and informal education
in developing countries might go a long way to better preparing
the children and young adults for the world of challenges that
faces them. With this question, I seek to explore whether it
is possible to develop problem-oriented learning approaches tailor-made
for effective implementation in the unique contexts of the many
developing regions of the world.

Paul Horwitz
Is problem solving a generic skill?
Is problem solving in science different from problem solving
in math, for example? How about problem solving in law, history,
human relations? Would Polya have made a great diplomat?
In the context of "complex
and long-term change" we're interested in people's ability
to "think outside the box" and react to situations
and circumstances that they had not anticipated. So the question
is: can one really isolate that ability from the context (which,
by definition, is not known in advance)? We know that mental
abilities are rarely "fungible." For example, teaching
kids chess does not improve their ability to do math or science,
nor are exceptional chess players particularly skilled problem
solvers in other fields. Does this mean that we should not focus
on problem solving skills, per se, and teach problem solving
only in very specific contexts?
11
Paul Horwitz
Can problem solving be taught? How
much of the observed variance in problem solving ability is attributable
to instruction and how much to "innate ability"? How
contextualized should problem solving instruction be? How metacognitive?
It's the fundamental credo of most
educators that "every child can learn" and most of
us would like to think that this applies to problem solving skills.
Do we have evidence for that belief? Assuming that the process
can be taught, how important it is to teach it in the context
of one or another discipline? And how important is it that the
problems to be solved be perceived as "relevant" by
the student? Aren't games and puzzles evidence that "irrelevant"
problems can be engaging? If practice makes perfect, doing puzzles
may make one an expert puzzle solver, but is that really what
we're interested in? Is it a good thing or a bad thing for a
child to think about her thought processes as she works through
a problem? Or is problem solving one of these intuitive things
that defies categorization and is killed by too much inspection?
(A lot of very good baseball players are reluctant to talk to
scientists anxious to learn how they do all that, for fear that
if they start to think about it they won't be able to.)
12
Paul Horwitz
Can problem solving be assessed?
Is it enough just to give people problems and ask them to solve
them? How does one differentiate rule-based, algorithmic problem
solving from creative, innovative problem solving? How does one
assess the process, rather then just the product, of problem
solving?
If you want to know whether someone
can play the piano, you don't ask a bunch of theoretical questions
-- you sit him down in front of a piano and ask him to play something.
So we test for problem solving ability in physics, for example,
by giving people problems and seeing whether they can solve them.
But the problems we give are often quite algorithmic (isolate
all the subsystems, identify all the external forces acting on
each subsystem, write an expression for the resultant force,
identify all constraints, solve the resulting equations for the
desired unknown quantity...") and don't necessarily reflect
the student's ability to be creative and flexible in unfamiliar
and unanticipated situations. Is there any way to assess that?
13
Elizabeth
Jordan (please see my conceptual statement here)
What elements within an environment/
atmosphere encourage, support and permit problem solving/creativity
to occur?
While there are lists of factors
that enhance creativity, such as risk taking, the environment
of a classroom contains subtle factors that influence the tone
of the class. During supervision of pre-service teachers you
can pick up that evasive air imparted by the teachers and administration
within a school and almost predict what kind of class environment
you will observe. How can that affect POL and building the scientific
mind?
14
Elizabeth Jordan
How does the formal school system
build boundaries on the flexibility necessary for enhancement
of creativity?
In many instances teachers are encouraged
to develop case and project based courses but revert back to
the more traditional lecture when exam time comes. This sends
mixed messages to students who are subtly being "told"
that in the end the only thing of value is the "right answer".
Again, how can that affect POL and building the scientific mind?
15
Elizabeth Jordan
Can the elements required for creativity
to be nourished be duplicated within the constraints of today's
education system? If not, then where does that leave PBL/POL
for building the scientific mind?
In many instances teachers are encouraged
to develop case and project based courses but revert back to
the more traditional lecture when exam time comes. This sends
mixed messages to students who are subtly being "told"
that in the end the only thing of value is the "right answer".
Again, how can that affect POL and building the scientific mind?
16
Elizabeth Jordan
To what extent is the potential
effectiveness of POL approaches in supporting the development
of a scientific disposition based on the attributes of a particularly
effective teacher? Is it possible to develop this supportive
teaching style or is it an inherent characteristic of some teachers?
17
Jason Ravitz
What are characteristic elements
of well-designed project-based learning that promote scientific
thinking and inquiry processes across the curriculum?
Effectively designed projects, in
any discipline, are really about promoting student inquiry. These
require students to engage in elements of scientific work such
as: Asking progressively better questions; continually reflecting
on what they know and need to know; considering alternative explanations;
assessing the quality of information and data; analyzing and
representing data, presenting and responding to arguments, critically
evaluating claims and evidence in order to draw conclusions,
developing ways of finding out or knowing, building on each other's
work, etc. In short, the inquiry process is common to both conducting
science and conducting project work. We should be able to promote
scientific thinking across the curriculum by recognizing and
building on these commonalities. It would be useful to come up
with exemplary projects from different subject areas that demonstrate
these processes of inquiry.
18
Jason Ravitz
What are skills or attitudes that
are important for scientific thinking that are lacking in traditional
science classrooms, and how can PBL help promote development
of these attitudes or skills?
In addition to supporting the processes
of inquiry in the previous question, PBL is a way to promote
attitudes and skills that are required by scientists and scientific
thinkers. For example, PBL can be designed to foster "21st
century skills" including interpersonal skills that are
often missing in traditional science instruction. Additionally,
conducting projects can require students to develop skills in
planning project work; managing the process of inquiry; communicating
results; confronting ethical dilemmas and values issues; engaging
in a peer review, thinking critically, persevering, and so on.
These are skills and attitudes that are required in the fields
of science and beyond. Arguably, effective design and use of
PBL can help foster attitudes and skills that are needed for
scientific thinking and a more scientifically literate citizenry.
19
Jason Ravitz
How can PBL be designed to more
closely resemble the ongoing and broad distributed investigations
that we would associate with the scientific disposition, i.e.,
going beyond the requirements of a single individual or course?
Can we design a PBL-based curriculum that builds on prior work,
is authentic and cumulative?
Too often projects take place as
isolated incidents among individual students, groups, or classrooms,
and years. An alternative approach would require students to
conduct inquiry that builds upon work conducted previously and
contributes new knowledge with each successive effort. In effect,
we might try to frame projects and problems so that students
learn to become contributors to scientific knowledge and are
able to experience the benefits of participating in collaborative
inquiry within a community of practice.
20
Jason Ravitz
How is technology changing the way
we understand, conduct, and define science and scientific thinking
and how is this reflected in the practice of PBL? Which problems
in the practice of science are being solved by technology? What
problems will technology solve in the future? What new problems
for scientific thinking have been created by new technologies?
Emerging technologies have the potential
to solve (or make easier) certain problems in the process of
scientific inquiry. Technology may be effective in solving certain
problems in the practice of science, at the same time that it
raises new problems. Some good ideas or required skills from
previous generations of science may have lost their utility or
become obsolete as a result of technology. For example, some
have argued that Google or YouTube-style rating systems may change
the way communities find and create knowledge, automating the
process so that it supplant the need for people to evaluate and
disseminate quality work, making it easier to create self-organizing
systems and so on. If we can design experiences in PBL for students
that reflect this new approach to knowledge we might help advance
their ability to contribute to knowledge in the future.
21
Dan Laitsch
How are problem-based learning and
the "deficit model" (the "problem" represents
a "deficit" to be addressed through a "treatment"
or disposition of knowledge) in the sciences related? What, if
any, are the implications of this for using PBL to foster the
scientific disposition?
Problem based learning, as a teaching
method, is one technique (among many) that can be used to stimulate
student learning. What are the implications of extending this
concept to an end state judgment (e.g. "conceptualizing
one's environment as made up of problems")? Do we then create
the equivalent of a "deficit/disease model" in education
that focuses on treatments and interventions, rather than on
creation of a positive (healthy) environment for life-long learning
that may carry us beyond the problems we define in life?
22
Dan Laitsch
Can/should PBL be envisioned to
fit within the broader context of a "settings approach"
(or behavioral or holistic model) that focuses on achieving a
healthy knowledge end-state or fulfilling individual "knowledge
potentials?"
23
Dan Laitsch
Does the highly contextualized and
specific nature of effective problem-based learning (PBL) potentially
diminish the effectiveness of PBL in nurturing a true, broad
scientific appreciation of the world around us?
24
Cindy Hmelo-Silver
What features of problem-based learning
(PBL) are important for different kinds of learning outcomes?
Different kinds of learning outcomes
are important for preparing people to be lifelong learners in
a complex and changing world. Goals of PBL include construction
of flexible knowledge and lifelong learning skills (and dispositions),
there are other possible outcomes such as learning to collaborate
and enhancing intrinsic motivation. All these outcomes are, we
hope, long term. Although proponents of PBL consider PBL as a
system, we need to better understand what is essential for which
kinds of learning outcomes and what the tradeoffs are of various
adaptations.
25
Cindy Hmelo-Silver
How can we scaffold learners of
different ages to be able to engage in problem-based learning
(PBL)?
If we want learners to deal with
the uncertainty of scientific knowledge, then it is important
that PBL be accessible to young learners. The models that have
been currently developed have been developed for advanced learners
and it would be naïve to expect that the models used for
medical students could be used for primary school children. Given
the realities of relatively large class size, the model of one
facilitator to a small number of learners is not tenable. Alternative
approaches need to be considered that will support students of
all ages in engaging in PBL and preparing them to be lifelong
learning in a complex society.
26
Cindy Hmelo-Silver
How can we help teachers learn to
facilitate PBL? What kinds of professional development are important?
A key issue in using problem-based
learning is being able to support students in engaging in realistic
problems that build on the student's thinking. Facilitating PBL
is challenging, both in terms of understanding relevant content
and being open to learning with the students. Beyond the difficulties
in learning how to facilitate, these issues become especially
urgent in considering how to facilitate larger classes. There
may be roles for technology in addressing some of these questions.
27
Marion Porath
Can POL contribute to the elaboration
and flexible use of core conceptual understandings in science?
Cognitive developmental psychology
tells us that the more sophisticated stages of scientific reasoning
are characterized by a coherence of core, or central, conceptual
scientific understanding that appears necessary but not sufficient
for creativity. However, not all learners achieve this coherence.
POL may allow opportunities to work with core understandings
in a way that builds first coherence and then the capacity to
use concepts flexibly.
28
Marion Porath
Is there an optimal balance
between POL and transmission of recognized knowledge traditions
in science?
Bruner talked about models of
mind that "drive" pedagogy. Uniting the knowledge of
learners who bring their own scientific conceptions to school
with the knowledge traditions of the discipline is one model
that can pose particular challenges for teachers (as compared
to the knowledge transmission or "show and do" models,
for example). Surpassing one's field entails first knowing it
intimately. Balancing the acquisition of accepted scientific
knowledge with opportunities to apply, question, and use knowledge
creatively is a pedagogical challenge.
Many students when asked about
hobbies and interests outside of a school atmosphere can regale
you with phenomenal examples of in-depth understanding on a topic,
extremely creative insights and activities, as well as an internal
drive to expand beyond their apparent capabilities and skills.
While the development of problems or cases for POL is a necessary
component there must also be an environment conducive or a learning
community to allow the flexibility necessary for problem solving
to occur. From Shavinina & Ferrari it becomes apparent that
creativity requires a specific internal fortitude to deviate
from the system and cultural expectations. This leads to questions
about the environment (the classroom and education system) we
expect students to work in. What is it about our environment
(and culture?) that requires people with extraordinary cognitive
abilities to feel a need to become a "maverick" in
order to problem solve and think creatively?
Creative individuals have survived and flourished despite the
education system. But within that system, how many people with
high potential do we loose? When supervising in science classrooms
I am still seeing that same traditional system being displayed.
Certainly factors like time constraints, provincial/state exams
(STA,GRE), and administrative support take their toll on a teacher
and his/her decision making but even within that can we not nurture
creativity? Risk taking? Diversity and validation of new ideas?
