The PoLS-T Network is an NSF grant of Eric Mazur at
Harvard University to support high school physics teachers worldwide, because
physics is crucial to civilization. It began in 2020. PoLS ~ physics of living
systems.
Abstract: Physics for ALL requires that we
teachers have 10 years of Deliberate Practice, to learn deep content and how to
teach it effectively, so that students will enjoy physics so much that they'll
want to keep learning it all their lives, and so that they'll convince other
students to take physics. K. Anders Ericsson has studied development of
expertise in a wide variety of endeavors. His conclusions are: it takes
typically 10 years of DELIBERATE practice; that is, examining your performance,
asking how you can improve it, and then taking specific steps to improve.
That's our purpose in Modeling Workshops.
But follow the money! Professional development (PD) has declined, due to
the Federal government ending crucial PD programs. Chief among them for physics
PD was the 2.5% set-aside for higher education grants for local PD, in the U.S.
Department of Education Title II-A formula grants to each state. We must work
to re-instate an automatic state set-aside, and target it for STEM teachers.
JaneÕs talk
(enhanced a little here, to explain things better. Sept. 2021):
Everyone is in some sense a physicist; we all encounter
physics every day and everywhere. Every time we move! And gravity, of course.
Studying physics increases our awareness of how the world (the universe) works.
ItÕs practical in daily life, enhancing our ability to do all sorts of
endeavors, from kitchen to garden to garage to sports field and beyond. Thus,
physics should be for ALL.
Physics for all requires that we teachers have 10 years of deliberate
practice, to learn deep content and how to teach it effectively, so that
students will enjoy physics so much that theyÕll want to keep learning it all
their lives, and so that theyÕll convince other students in their high school
to take physics. As Eugenia Etkina said on June 19 to the PoLS-T Network: young
people are natural learners; and we need to enhance this, in ways that she
described in her talk -- including thinking like a physicist; evidence-based
thinking; building and refining scientific models; system thinking; and flow
experiences. EugeniaÕs Investigative Science Learning Environment (ISLE
and PUM) are super-compatible with Modeling Instruction. Physics teachers need
PD in these two outstanding programs. (EugeniaÕs June 19 discussion is at https://www.youtube.com/watch?v=mg9ryJya9Ng
. A link to her June 16 talk is there: https://www.youtube.com/watch?v=ldr1cOk8wGE
)
IÕm going to touch on legislation, so I speak in this talk
as a private citizen. My views are my own. In this talk I donÕt represent any
institution or organization.
WhatÕs troubling is that science teacher professional
development (PD) has declined in recent years. Horizon Research documented the
decline.
(Trends in U.S. Science Education from 2012 to 2018, by P. Sean Smith. 2020,
Horizon Research, Inc. https://eric.ed.gov/?id=ED611301
)
Why has it declined? Because the Federal government ended
crucial PD programs, making PD much too expensive. Chief among the programs
that served physics teachers was the U.S. Department of EducationÕs 2.5%
set-aside for colleges (institutions of higher education – IHEs) in their
formula Title II-A grants to each state. That provided $1 million to Arizona, each year, for teacher
PD.
We must work to re-instate an automatic higher education
set-aside for states, and target it for STEM teachers; that seems to be the
easiest approach to increase free local PD opportunities, because it involves simply
amending a few paragraphs of existing legislation.
But first, why do we teachers need 10 years of deliberate
practice, to become experts? I quote David Hestenes, co-founder of Modeling
Instruction. In 1995 to 2000 he had a huge NSF grant for Leadership Modeling
Workshops for 200 expert teachers nationwide. He said to a group of 50 of them,
in their 3rd summer at ASU in 1997, the following:
-------------------------------------
Back in 1985 we published the first data on the Mechanics
Diagnostic Test, a precursor to the Force Concept Inventory (FCI). Malcolm
Wells was the first person to apply this test to his high school class. His
gains were low; his mean posttest score was about 45%, which we now know is
typical for traditional physics instruction. But this was an epiphany for him,
because he had put in tremendous effort at improving his instruction, and he
was using most of the activities and general approach that you are using:
photogates and computers -- yet he got these gains which werenÕt good. (Malcolm
Wells didnÕt have "a natural gift" for teaching, by the way, but he
worked very hard on refining his technique.)
However, by the time he finished his dissertation, 3 years
later, he made a BIG gain, among the highest FCI gains ever achieved! É This
example shows that it is definitely possible to improve considerably. É
Researcher K. Anders Ericsson has studied development of
expertise in a wide variety of activities, from chess-playing and concert
playing to performance in many fields of endeavor. He doesnÕt talk specifically about teaching. But he comes up
with some general features of those people who become expert. They are
universal across the different domains. Let me review the main points.
The first point is that IT TAKES A LONG TIME TO BECOME
EXPERT in any complex domain. In fact, the time period is about 10 years.
Consider a person devoting all his time to playing chess. He may be a young prodigy or start
later; there is an advantage to starting young, but it still takes 10 years
before you can perform at the level of the outstanding experts. This is
documented in areas where we have explicit data on performance. There is every
reason to believe that it applies to teaching as well.
But 10 years isnÕt enough by itself. Another of EricssonÕs conclusions is
that experience doesnÕt necessarily produce improvement. So just because you
have 10 years of teaching, it doesnÕt mean that you are any better a teacher
than you were when you started out.
In fact, with respect to concert playing with musical instruments, he
has data that show that just performing in concerts doesnÕt improve your
skill.
What DOES improve your skill? It is what Ericsson calls DELIBERATE PRACTICE and that is
EXAMINATION OF YOUR OWN PERFORMANCE AND ASKING HOW YOU CAN IMPROVE IT, AND THEN
TAKING SPECIFIC STEPS TO IMPROVE. ThatÕs what WEÕRE trying to help you do in
the Modeling Workshops! DELIBERATE
PRACTICE over 10 years is as necessary to become an expert in teaching as in
any other field.

------------------------------------------------
Did you know about K. Anders EricssonÕs research? I had no
idea, when I was teaching physics. I wish IÕd known; it would have motivated me
to seek in-depth PD. I would have been a better teacher!
In David HestenesÕ NSF grant, the 200 physics teachers gave
the Force Concept Inventory as a baseline posttest to their students before
they took their first 4-week summer Modeling Workshop, and then after the
workshops as pretests and posttests. Results showed that Modeling Instruction
is highly effective pedagogy; its effect size is large: 0.9, satisfying the What Works Clearinghouse standard for
effectiveness. Modeling Workshops are deliberate practice!
(See http://modeling.asu.edu/R&E/FCI-LargeEffectSize.htm
)
I have 23 years of experience writing grants for physics
Modeling Workshops. I have ideas on how the physics teacher community can work
to restore affordable PD thatÕs deliberate practice – working toward our
vision of physics for all. HereÕs my story.
In addition to overseeing the 200 teachers in Leadership
Modeling Workshops, I wrote grants yearly since 1998, for Arizona teachers to
have summer Modeling workshops at ASU. Until 2005, I got $50,000/year in the Federal Title II-A Eisenhower Math and Science Professional
Development program of the U.S. Department of Education. Each year I served
2 dozen physics & physical science teachers. Teachers got stipends and free
ASU tuition. Enrollment increased, sometimes a LOT! The effect size was huge, with
these teachers.
In general, Eisenhower grants were $50,000, and the entire
state of Arizona was served in 15 to 20 grants each year, by faculty at ArizonaÕs
3 universities who were passionate about science. Faculty volunteered, hosting
up to 25 teachers each; the Eisenhower program worked well. *(Appendix I is an
overview.)
In 2000, David Hestenes got another NSF grant to expand Modeling
Workshops to other states. So, in addition to my Arizona PD work, I built an
informal network of 2 dozen college physics faculty in 18 states, and I helped
them get Eisenhower grants for Modeling Workshops in their locale. These grants were typically
$50,000. Some of the 200 teachers
in David HestenesÕ first NSF grant led the workshops; in fact, they recruited
the faculty. The workshops helped alleviate the nationwide shortage of
qualified high school physics teachers. The faculty are listed at our website,
modeling.asu.edu . (at http://modeling.asu.edu/Partners.htm ). **
The Eisenhower program was replaced by 2004 with the Title
II-A "Improving Teacher Quality" program in ÒNo Child Left BehindÓ (Elementary & Secondary
Education Act – ESEA). Unfortunately,
the PD focus was broadened (diluted)
to all core subjects in K-12, and further diluted by adding PD for
principals. Some states chose to narrow it to focus on high-poverty school
districts – disregarding the extreme shortage of physics teachers at schools
of ALL socioeconomic levels. These changes made the program worse for physics.
(Appendix II is an overview.)
Grants got bigger and fewer, and less money went to
teachers. (More money went to administration and evaluation). It became harder
for physics faculty to get grants, (They were all VOLUNTEERS -- this is
important!). The result was disastrous
for physics teacher PD in some locales – for example, St. Louis,
Missouri, where the professor was denied funding because not enough of his
physics participants taught in high-poverty schools. Within a few years, hardly any
physics faculty could get grants from the "Improving Teacher Quality"
program.
At ASU, we thrived until 2010: our yearly grant at ASU
increased in 2006 to ~$250,000 for 100 teachers -- but I could no longer do the
work as a volunteer, because I had to add chemistry and junior high physical
science to get the grant, so my workload got too big. ItÕs an inefficient use
of funds! (I had to hire administrative staff -- hard to get, because
short-term. Risky – in one- or two-year grants, staff arenÕt assured of job
continuation. Job training slows down the work. You must act fast when you get
a grant.) Our 5 summers of Modeling Workshops produced 80 highly qualified
teachers from those who were teaching out-of-field, and highly qualified teachers
became more effective.
After 2010, we at ASU were cut out of the grant process,
because the AZ Board of Regents decided to fund ONLY math in one year, and only
elementary school PRINCIPALs in another year. They were running scared, because by 2010, the Federal government was threatening to
end the ÒImproving Teacher QualityÓ program, so the AZ grant managers wanted
the biggest bang for the buck: they wanted to improve the math test scores
statewide, since math was high-stakes but science wasnÕt.
By 2015, only Ohio was still able to get ÒImproving
Teacher QualityÓ funding. (Ohio had a wise higher ed agency, who recognized the
long-term systemic need for physics.) But in December 2015 the Improving Teacher Quality program ended.
ÒNo
Child Left BehindÓ was replaced by ESSA, the ÒEvery Student Succeeds ActÕ. The
2.5% set-aside ended, period. Ohio
Modeling Workshop enrollment in physics went from 100 down to zero, in the
space of a year. Nothing.
The Federal government
provides NO money now, for colleges to organize PD for teachers. Instead of
teachers getting a stipend, they must pay almost $800 for a 3-week summer
Modeling Workshop hosted by the American Modeling Teachers Association, AMTA.
This is too expensive for many public school teachers to pay out-of-pocket, and
their schools donÕt have enough Title II-A funds to pay. So private school
teachers are predominant participants. (See
https://www.modelinginstruction.org.
You can read relevant excerpts of the ESSA Title II-A legislation at http://modeling.asu.edu/modeling/ESSA-TitleII-STEMtchrPD.htm
)
What about us at ASU? For the past 10 years, weÕve existed
on donations from local businesses -- a very time-consuming process, and
donations are much LESS than $50,000 – typically $15,000 for 50 to 60
teachers. Few corporations give,
and (with a few exceptions like Salt River Project and ON Semiconductor) they
donÕt give much. It is foolish of the Federal government to rely on corporate
gifts for teacher PD. I work almost full-time but there is no grant to pay me,
so most of my work is volunteer. We had to stop offering PD in physical
science, because recruiting 8th & 9th grade teachers
was too hard, since they got no stipend, no tuition waiver. Free tuition is a powerful incentive!
At ASU, teachers must PAY $400 for our Modeling Workshops,
for non-credit. Or if they want ASU graduate credit, they must pay $2200
tuition/ course. To help them, I write grants to local companies each year –
and get typically $15,000 in donations. It is time-consuming and unproductive.
I couldnÕt even convince my bank to give $1000 this year.
BOTTOM LINE: no program is left from the Federal government,
to fund summer professional development for physics teachers. This bodes ill
for the nation's future economy, since high school physics is the chief pathway
to STEM careers and STEM majors in college.
Looking more widely, we need thinkers in this nation, as
Eugenia Etkina said. Everyone is in some sense a physicist; we all encounter
physics every day and everywhere. And societally, we must face the global
climate crisis. What kind of world will young people inherit? Sea rise, extreme
drought, vast fires, huge migrations – you know. To slow this devastation,
we need to love the physical planet, our only home, so that weÕll honor and
preserve its resources. Love encompasses and includes understanding. If we understand
physical reality, we will love our planet more. Understanding implies
evidence-based thinking; thinking like a scientist, as in Modeling Instruction,
ISLE, and PUM. Then intelligent actions can follow. So we need physics for
all in this crucial time in civilization!
Singapore seems to be aware of this. Physics is taken by
most high school students; and teachers are expected to take 60 to 90 hours of
PD every year, according to Singapore teachers whoÕve been sent by their
Ministry of Education to take ASU Modeling Workshops. So they know about the
need for deliberate practice.
I have 3 practical suggestions for the U.S. Department of
Education to restore funding for PD that is deliberate practice – i.e.,
meaningful effective disciplinary PD:
1) Make it
affordable and attractive! Return to the central ideas of the Eisenhower
program: a set-aside in state formula grants for Title II-A, focus on science,
focus on deep content with effective pedagogy, open to all socio-economic
strata; free tuition and/or stipends.
2) Require small grants: HUGE grants are
counterproductive. They benefit few teachers relative to the wasted money on
administration and external evaluation. Grants are risky and short-term, making
it hard to hire personnel. Better to spread the money farther by having $50,000
to $100,000 grants. This would enhance the volunteer, local aspects: physics
and chemistry faculty are willing to volunteer to organize a summer 3-week
workshop for 20 teachers.
3)
Prioritize high school physics and chemistry, the two core sciences that interface
most closely with college and technical post-secondary trade schools, and thus
get most commitment from post-secondary faculty to organize summer workshops. Physics
and chemistry have the worst chronic shortages nationwide; e.g., ¾ of
physics teachers in Arizona earned their degree in some other subject. Arizona
produces 8 physics teachers per year, ~15 chemistry teachers, and 65 to 80
biology teachers, each year. The Eisenhower math and science PD program
targeted out-of-field teachers, and that is still a central need. (See Appendix I. References are at http://modeling.asu.edu/AZ/PhysicsEnroll-NeedDouble.htm) ***
Legislation for teacher PD is quite simple: a few short
paragraphs. PoliticiansÕ staff experts can write the legislation, but
advocating for it is a task for physics leaders like Eric Mazur, who have
connections in Washington, DC, and for organizations like the AMTA and AAPT,
and networks like PoLS-T Network. This is policy, not politics.
IÕve tried to show here what IS possible. We must do
something, and restoring the Title II-A set-aside for higher education seems
the EASIEST way to increase local PD in physics. Of course, it should be on a
higher turn of the spiral – requiring research-validated strategies like
Modeling Instruction and Eugenia EtkinaÕs ISLE – ideally, both together,
in continuous improvement.
Modeling Instruction is described at
http://modeling.asu.edu. Weblinks to ISLE and PUM are at Ôweblinks for modelersÕ
there (and many weblinks to high-quality resources).
END NOTES:
* Some of
us faculty cooperated: In physics, in 1998 I convinced a physics professor at
Northern AZ University and also at the University of Arizona to submit nearly
identical proposals. All 3 of us got $50,000 grants; thus we provided 4-week
summer physics Modeling Workshops for ~70 teachers, over 2 summers. That was
1/3 of the physics teachers in Arizona. It made a huge positive difference in
the quality and quantity of physics, for several years. But it doesn't last; teachers retire.
The economic recession in 2008 did terrible financial damage to schools. Many
Arizona schools dropped physics since then, when their physics teacher retired.
**They were at 2 universities in Ohio, 2 in Maine, 2 in
Wisconsin, 2 in Virginia, 2 in Missouri. Also New York, Massachusetts, Iowa,
Hawaii, Pennsylvania, South Dakota, California, Florida, Indiana, Iowa,
Arkansas, Michigan, Tennessee.
*** An endeavor by the National Academy of Science lends
credence to these practical suggestions. In 2005, in order to think about the
future economy, they convened a K-12 Education Focus Group. That groupÕs top 3
recommendations for STEM teacher PD were (1) in-depth content and pedagogical
knowledge; (2) scholarships for summer institutes and content-intensive degree
programs; and (3) seed grants to universities for these two types of teacher
PD. (No recommendation was
implemented, sadly.)

I. Eisenhower Professional Development Program, Request for Proposals (July
2001) Arizona Board of Regents.
I quote from the introduction:
--------------------------------------
The purpose of the Eisenhower Professional Development
Program is in part to strengthen the economic competitiveness and national
security of the United States by improving the skills of teachers and the
quality of instruction in mathematics and science, and other core subjects in
the nation's public and private elementary and secondary schools through
assistance to state educational agencies (SEAs), local educational agencies
(LEAs – usually school districts), and institutions of higher education
(IHEs).
The State Agency for Higher Education (SAHE) shall make
funds available on a competitive basis to institutions of higher education in
the state which apply for payments under this section and which demonstrate the
involvement of local educational agencies. The State Agency for Higher
Education shall make every effort to ensure equitable participation of private
and public institutions of higher education.
The amount available shall be used for:
a. establishing preservice programs to prepare new
teachers who will teach mathematics and science, and other core subjects;
b. retraining of secondary school teachers who specialize
in disciplines other than the teaching of mathematics or science, including the
provision of stipends for participation in institutes É; and
c. inservice
training for elementary, secondary, and vocational school teachers and training
for other appropriate school personnel to improve their teaching skills in the
fields of mathematics and science, including stipends for participation in
institutes É
Each
institution of higher education receiving a grant under the subsection shall assure that programs of
training, retraining, and in-service training will take into account the need
for greater access to and participation in mathematics and science careers by
students from historically underrepresented and/or underserved groups,
including females, minorities, individuals with limited English proficiency,
the handicapped, and the gifted and talented, and will ensure cooperative
agreements or cooperative arrangements with local educational agencies.

APPENDIX III: a quote by David Hestenes
"Lifelong
professional development is as essential for science teachers as it is for
doctors. Typically, it takes at least 10 years of deliberate practice to reach
a high level of expertise in any profession. Few teachers have adequate
opportunities for sustained professional development, and many have an
inadequate background in science to start with, so most remain far from
reaching their full potential as teachers. ... teachers need access to lifelong
professional development like that provided by the AMTA in Modeling
Workshops."
