A key part of that curriculum, as presented in the Committees 1893 Eliot
Report, was geology and physical geography. The Eliot Report said that students
in their fourth and fifth years of secondary school should spend a class period
learning earth and atmospheric studies. The Committee included such geologic
luminaries of the time as Thomas C. Chamberlin, George L. Collie, W. M. Davis
and Israel C. Russell.
More than a century later, todays education leaders are having many of
the same conversations as those in the Committee of Ten. The impact of a host
of initiatives intending to spur on instructional improvements and greater public
knowledge of the importance of earth science, has been limited. Despite past
and present efforts, many of the same fundamental problems recognized in 1892
still prevail.
The push for establishing geoscience education in our public schools goes beyond
the Eliot Report. History is replete with examples of geoscience education interest
and effort. Grove Karl Gilbert, serving as the Association of American Geographers
President, convened a special Round Table Conference in 1909 to discuss some
of the problems associated with secondary school physical geography.
Writing in the Journal of Geography (v.7, p 145-157), they cited some
of the problems in education as not meeting the real needs of most students
being over-systematic and often unreal
not providing useful knowledge
of the subject. Optimism prevailed, though, as conference participants
noted that time is ripe for a change and that the chief problem
of lacking proper instructional materials will undoubtedly promptly be met by
publishers as soon as change is seen to be imminent.
In 1957, participants in The International Geophysical Year, spurred on by Sputnik-driven
attention to science education in the United States, spoke frequently about
the need for better earth science instruction in our public schools. The Earth
Science Curriculum Project (ESCP) of the 1960s was a significant response to
this national interest. J. Tuzo Wilson, Richard Jahns, Mason Hill and Rachel
Carson were just a few of the distinguished ESCP Advisory Board members who
were enormously influential in formulating the instructional philosophy and
course content. They, with the help of the American Geological Institute (AGI),
were responsible for the rapid growth and expansion of earth science in the
school curriculum. At the same time, even though more than 190,000 students
were taking ESCP earth science, the ESCP staff and board members frequently
expressed concern over the availability of a competent corps of earth science
teachers (ESCP Newsletter, 1963, v.1, n.1).
Science and educational organizations have worked during the past decade on
a range of instructional reform efforts to set forth what students should know
and be able to do in science. In order to bring some coherence to well-intentioned
but increasingly voluminous, overlapping and at times contradictory recommendations,
the National Research Council developed the National Science Education Standards.
Released in 1996, the NRC Standards grew from a multiyear effort involving hundreds
of scientists and educators. By most assessments, the NRC Standards have been
successful in presenting the principles and vision for science education, and
they serve as the keystone for most instructional and curricula reform efforts.
More importantly, the NRC Standards show not only geoscientists, but also physicists,
chemists and life scientists all calling for a strong and fully equal earth
science presence in the curriculum. This attention to earth science is driven,
in part, by the increased focus on the usefulness of science and the recognition
that earth science contributes significantly to how we utilize our resources,
manage our land and mitigate the effects of natural disasters. Moreover, scientists
from other disciplines recognize how the earth sciences provide important context
and meaning for acquiring fundamental understandings in their disciplines.
History repeats itself
According to State Indicators of Science and Mathematics Education 2001, published
by the Council of Chief State School Officers (CCSSO), of the roughly 13 million
high school students in our nation, less than 7 percent (860,000) will take
a high-school earth and space science course, a number far lower than the 88
percent of students who will take biology. In 1962, according to the U.S. Department
of Educations National Center for Education Statistics, 190,000 students
per year, or 760,000 over four years, out of almost 9 million would take high-school
earth and space science courses. Thats about 8.5 percent. Since 1962,
the number of secondary school students has increased by 31 percent. Given this
increase, the enrollment situation in earth science appears to have gotten worse,
not better.
With all the interest in enhancing geoscience education, why does this apparent
disconnect remain? Why havent interest and activity led to greater achievement?
Indeed, other disciplines face similar, ongoing educational challenges, and
their leaders recognize that their health and viability are ultimately linked
to these educational efforts.
What these other science areas dont face, at least to the extent that
earth sciences do, is the challenge of having an adequate, well-trained corps
of teachers. This lack of certified teachers is especially problematic to our
discipline and historically has been the limiting factor in our enhancement
and development efforts. National initiatives may spur on a need for earth science
teachers and even create new positions, but the opportunity they provide for
a new-found presence can disappear like skywriting. An inadequately prepared
teacher, or even a well-prepared teacher who is teaching out of their certified
area, is not likely to develop that necessary level of course following,
to establish the course as worthwhile, or to inspire student interest. The subject
matter might not be their first love and, consequently, they are not the best
ambassadors for our science. The result: earth science courses decline in enrollment
and, sadly, many school systems take the expeditious action to simply eliminate
the requirement.
The National Science Teachers Associations National Teacher Registry shows
17,658 teachers instructing grades seventh through 12th in classes categorized
as earth science. (An undeterminable number could have a split assignment, teaching
one other course or several other courses.) Also, the most recent CCSSO report
shows slightly more than 14,000 earth science teachers for ninth through 12th
grades, compared to slightly more than 51,000 biology teachers. Of especially
important note, the CCSSO reports in State Indicators that many states
and districts are having difficulty hiring and assigning well-prepared teachers
in the field of earth science.
Time for a new strategy
Over the years, the National Science Foundation (NSF) has supported many local
and national teacher enhancement programs short-term training programs
that add to teachers knowledge of their subject areas or teaching methods.
Many of these programs are summer workshops, while a smaller number are part-time
through the academic year. All of these programs are needed and worthwhile initiatives
that give earth science teachers more competence and confidence.
Yet, the percentage of teachers affected by these programs is relatively small
and this percentage doesnt begin to factor in the huge number of new earth
science teachers needed to advance the teaching of earth science. While these
enhancement programs make significant contributions, they simply do not put
us on the right side of the curve of our national need. We need
to initiate programs that will develop a far greater number of earth science
teachers.
In State Indicators, CCSSO also writes: Many states have moved their policies
on teacher licensure toward requiring teachers to have more subject knowledge
preparation in the field they will be teaching. In the 1990s, states established
policies that require new teachers to have an undergraduate or graduate major
in their chosen teaching field. These states are acting to prevent a path to
teaching with a bachelors degree in education but without a major in a
particular subject area.
On June 11, the Department of Education delivered a new report to Congress called
Meeting the Highly Qualified Teachers Challenge. The report makes a key recommendation:
States across the country should revamp their certification requirements
by de-emphasizing traditional education courses and requiring prospective teachers
to pass rigorous exams in the subjects they plan to teach. This inaugural
report goes on to say that states should do more to deepen the pool of potential
teachers by opening alternative routes to the classroom for those who have strong
content knowledge but lack some of the education theory classes.
We have a need and a historically unprecedented invitation that we should not
let pass by.
The geology education degree
We need to facilitate ways for students to earn both geology degrees and education
degrees. Students holding such degrees will provide a teacher corps that can
correct this historic underrepresentation of earth science in education.
Colleges and universities offer programs that lead to teacher certification,
but only states have authority for granting certification or, in some cases,
licensure. (A program of study can be submitted to the states education
department for approval.) Courses in teaching and education are important and
officials will want to see some appropriate amount of professional course and
field-based experience. But most states do provide alternative routes to certification,
and education course work need not be a limiting factor for someone who wants
to teach. The benefits of such programs to both the pre-college and college
sectors are enormous (Geotimes, September 1999). Many colleges or departments
of education also see the broader benefits of opening their programs to a more
diverse group of majors. Through careful planning, departments can often use
areas of a degree program, such as distributive studies, electives or advanced
courses, for the requisite education courses.
At some liberal arts colleges, students who want to obtain teacher certification
simply earn a second major in addition to their geology major. At other liberal
arts colleges and at larger, comprehensive colleges and universities, the programs
proceed on two somewhat similar, yet different tracks. To broaden the science
base of the pre-service teacher, the teacher preparation track may actually
include a greater number of science courses drawn from other discipline areas
than the geology major.
At many of the research universities and doctoral granting universities, students
find that in order to enroll in science education programs they have to drop
their science majors. As can be expected, most of these students are unwilling
to make this choice. The result is that, all too often, science majors graduate
with a weak background in pedagogy, or education majors graduate with a weak
background in science content. Collectively, these institutions have huge undergraduate
enrollments approximately equal to five times the collective enrollment
of all liberal arts institutions and even larger than the total enrollments
in all comprehensive colleges and universities. Students pursuing geoscience
degrees at research universities are frequently unable to take the courses necessary
to earn state certification for teaching.
Creating programmatic opportunities for students to become geologists and teachers
will not only help geoscience education, but also the geoscience profession
as a whole. Throughout most academic institutions the story is the same: a student
taking an introductory geoscience course to fulfill a science requirement finds,
usually unexpectedly, that they enjoy the material; they stumble
into geology. This practice speaks to the inherent interest and appeal of our
discipline, but it is a highly limiting and restrictive mechanism for generating
broad awareness of and interest in the discipline. David Curtiss, this years
AGI Congressional Science Fellow, writes in the May 2002 Geotimes that if
a student is not exposed to earth science in high school, the chance of that
student pursuing it in college is slim.
This years Geoscience Trends, compiled by AGIs Human Resources
Department, shows that the current number of geoscience degrees granted is less
than half of what it was just six years ago and a third of what it was 20 years
ago. These historic lows in the number of geoscience degrees being awarded is
cause for concern as program support, in most instances, is inherently based
on interest, need and production.
Its also true that students taking science classes just to fulfill science
requirements for other majors make choices based on some level of interest and
familiarity. In this sense, the health of every geology department, in terms
of student interest and enrollment, is linked to the state of our pre-college
earth science instruction and, as a result, the quality of the national earth
science teaching corps.
Works in progress
Some encouraging signs show that the recommendations for establishing discipline-based
teacher preparation programs are beginning to take hold. For example, The Geological
Society of Americas (GSA) Education Task Force report, New Directions
for Excellence, identifies the need for a teacher preparation initiative that
visibly and tangibly contributes to fundamental and durable change.
The report goes on to state: a geoscience education effort directed toward
enabling faculty to establish programs to help geology majors obtain teacher
certification in conjunction with their geoscience degrees can be shown to provide
direct benefits to a much larger sector of societal members. Preparation of
competent earth science teachers attracts students, contributes to departmental
growth, and develops a cadre of professionals who can further contribute to
the mission of the Society.
Recognizing that earth science with its increased emphasis on Earth as
a system and expanded use of Internet resources is emerging as an exemplar
for innovation and science education reform, a national conference last year
focused on developing effective instructional approaches and finding ways to
broaden student participation. Supported by NSF, the conference report Revolution
in Earth Science Education states the need for programs to produce, recruit
and retain earth science teachers. It calls for a national campaign that
would reach out to departments with undergraduate programs and to professional
societies to recruit sufficient numbers of trained and qualified teachers. (Geotimes,
September 2001).
The American Geophysical Union (AGU), with support from NSF, formed a collaboration
of universities to address the obstacles geoscience majors face. The collaboration,
called Linkages, is working to design programs that would link teacher preparation
classes and science content classes. Participating institutions have grown to
include: University of Arizona, University of Oklahoma, University of Washington,
Montana State University, New Mexico State University, San Diego State University
and Northern Arizona University. Programs being developed at these institutions
take various forms. Some are developing four-year programs, other programs include
a fifth year.
Institutional programs involve a level of curriculum revision, with some requiring
new courses. All of the programs include a research experience for students.
Because of needed revisions, many of the programs remain works in progress.
But the work these schools are doing has, in recent years, garnered interest
and has been reported on at AGU and GSA meetings, and at meetings of the American
Association for the Advancement of Science.
Michigan Tech recently instituted a teacher program that allows undergraduates
to obtain both a bachelors degree in geology and an earth science teaching
credential in four years. The program is designed for undergraduates who are
interested in becoming teachers but who also wish to maintain strong ties to
the academic department that most closely matches their content area. The dual
degree gives students the flexibility to either pursue a teaching career or
to continue their disciplinary studies by attending graduate school and seeking
employment as a professional geologist. This flexibility is attractive to many
students who would like to teach at some point in their careers but who are
unwilling as undergraduates to commit themselves to a single career path.
Also this academic year, the University of Maryland has introduced a bachelors
degree in geology and secondary education. The program retains all the supportive
science and mathematics requirements, field camp and senior thesis, and also
adds a course in meteorology and 12 credits of course work in education. The
undergraduate program prepares students for taking the Praxis teaching certification
exams and, in some cases, allows graduates to start teaching in school districts.
The university is also offering an optional, one-year, full-time graduate program
within the College of Education that leads to a masters of education and
permanent state certification.
This attention from universities and colleges on developing well-trained science
teachers is belated but welcome. Initiatives for developing a sufficient and
well-prepared pool of earth science teachers is, at long last, positioning us
to better contribute to broad public awareness of the profound importance of
our science.
Postdocs
needed in schools
Qualified science and math teachers are a scarce commodity in U.S. schools.
And that needs to change, according to a National Academies' National
Research Council (NRC) report released in July. The report recommends
the creation of a national fellowship program to attract recent science
and math doctorate graduates to kindergarten through 12th grade (K-12)
teaching. Lisa M. Pinsker |
