2Inquiry Works Best
- Research shows that students learn science best
by engaging in hands-on minds-on lessons through
a inquiry based curriculum (Abell and Bryan,
1997 Stepans, et. al., 1995 Metz, 1995
Glasson, 1989).
3What is inquiry in K-12 science education?
- Inquiry as defined in the National Science
Education Standards (NRC, 1995) - a multifaceted activity that involves making
observations posing questions examining books
and other sources of information to see what is
already known planning investigations reviewing
what is already known in light of experimental
evidence using tools to gather, analyze and
interpret data proposing answers, explanations
and predictions and communicating the results. - Inquiry requires identification of assumptions,
use of critical and logical thinking, and
consideration of alternative explanations.
4Goals for All Students
- Learn the principles and concepts of science (the
big ideas). - Be able to do science (the procedural skills and
mental reasoning abilities needed to carry out an
investigation). - Understand the nature of science as a human
activity, a way of constructing knowledge.
5Skills are more important than knowledge
6NSF Standards for Inquiry
- Students should be able to
- Identify questions and concepts for
identification - Design and conduct investigations
- Use technology and math to aid an investigation
- Formulate explanations using logic and evidence
- Analyze alternative explanations
- Communicate and defend an argument
7NSF Standards for Inquiry
- Students should understand that in science
- Investigations involve asking a question and
comparing the answer to what is known - Explanations emphasize evidence
- Explanations have logically consistent arguments
- Investigations are repeatable by others
- Scientists make their results public, review and
ask each other questions
8Unexpected results are often the most important
9Classroom Inquiry as a Teaching and Learning
Strategy
- Learners are engaged by scientifically oriented
questions - Learners give priority to evidence, which allows
them to develop and evaluate explanations that
address scientifically oriented questions - Learners formulate explanations from evidence to
address scientifically oriented questions - Learners evaluate their explanations in light of
alternative explanations, particularly those
reflecting scientific understanding - Learners communicate and justify their proposed
explanations
10Research Base on Learning
- People build new knowledge and understanding
based on what they already know and believe
(prior knowledge) - Understanding science is not just knowing facts
people must organize and actively build them into
a conceptual framework to be useful in new
settings (constructivism) - People need to monitor and reflect on their own
learning as they learn (metacognition)
How People Learn, NRC 1999.
11How People Learn
- Individuals do not obtain knowledge by
internalizing it from the outside but by
constructing it from within, in interaction with
the environment (Kamii, Manning, Manning, 1991
Perkins, 1992 Piaget, 1969 Vygotsky, 1978)
12Constructivism
- Constructivist views of learning provide a
theoretical framework to teachers in helping
students reconstruct their own understanding
through a process of interacting with objects in
the environment and engaging in higher-level
thinking and problem solving (Driver, Asoko,
Leach, Mortimer, Scott, 1994).
13Inquiry Is Scientific Method
- Constructivism provides the theoretical framework
for all forms of project-based learning (Grant,
2002). - PBS pedagogy (Schneider, Krajcik, Marx,
Soloway, 2002) assumes that students constantly
ask and refine questions design and conduct
multiple investigations gather, analyze,
interpret, and draw conclusions from data and
report findings. - . . . by extension, learning scientific process
(literacy) extends beyond the classroom
(Bransfield etal, 1999).
14Science starts with careful observation
15Careful observation means being prepared (making
predictions)
16Mastery of facts is not necessarily understanding!
- Ideas must be organized or built by the learner
into a conceptual framework in order to be
useful. - Students sort physics problems by superficial
features. - Experts sort problems by concepts.
17The Monotillation of Traxoline
- It is very important that you learn about
traxoline. Traxoline is a new form of zionter.
It is monotilled in Ceristanna. The
Ceristannians gristerlate large amounts of fevon
and then bracter it to quasel traxoline.
Traxoline may well be one of our most lukised
snezlaus in the future because of our zionter
lescelidge. - 1. What is traxoline?
- 2. Where is traxoline monotilled?
- 3. How is traxoline quaselled?
- 4. Why is traxoline important?
18Use Evolutionary Psychology
- E.O. Wilson stated, the benefits of metaphor over
analogy in teaching science is rooted in our
evolutionary past. We use metaphor to make sense
of our world.
19Scientific Method
- Scientists explore the physical world for
reproducible patterns which they represent by
models and organize into theories according to
laws (Hestenes, 2004).
20The acquisition of knowledge does not destroy the
beauty of experience
21Strategies for helping concept-building
- Plan activities (hands-on, minds-on) rather than
lectures - Have students predict-observe-explain
- Have students work in groups
- Have students relate ideas to existing knowledge
- Be a guide on the side, not a sage on the
stage
22Metacognition Thinking about Thinking
- Connecting new information to prior knowledge
- Selecting thinking strategies deliberately
- Planning, monitoring and evaluating own thinking
processes
23A statistic requires at least three data points
24Common sense is part of science
- Q. An army bus holds 36 soldiers. If 1128
soldiers are being bused to their training site,
how many buses are needed? - A. 31 R 12
- B. 31
- C. 32
25Use Scientific Method
- Simply providing knowledge without experience or
vice versa does not seem to be sufficient for the
development of metacognitive control (Livingston,
1996). - The scientific process (historically and in a
philosophical perspective) is the ultimate
metacognitive strategy for problem solving.
26Science is interdisciplinary
27Use your whole brain
- Three books are sitting on a shelf. Each book is
two inches thick with front and back covers 1/6th
of an inch thick. If a book worm chews threw the
books from page one of the first book to the last
page of the last book, how many inches does the
book worm chew through?
28Conclusions are only as good as the assumptions
that go into them
29New discoveries lead to new problems
