A
fascinating science, astronomy is also a means to reach across cultural
borders.
The
Outreach Program
Our
program is modeled after the ASP's ASTRO
program, pairing astronomers and teachers (see "Matches Made
in the Heavens," Sept/Oct 1994, p. 24). Each of us works with one
teacher at a different school, a different teacher at a different
school each year. Throughout the year we make numerous visits to
our chosen classes and perform hands-on astronomy activities with
the class. At least once per year we hold a nighttime star party,
inviting parents, family, and community members. The participation
of parents in the education process of their children is important
to the success of that process, and star parties are an excellent
way to foster this involvement.
We
attempt to address the problem of limited reach (we usually interact
directly with only twenty to thirty students per year) by incorporating
a "teacher-training" aspect to our program. Because they are full
partners in the classroom activities, teachers learn about the activities
so that they can do the exercises with their other classes. We supply
the materials for the activities and discussion, including color
pictures, notes, gas discharge tubes, etc., and we leave the supplies
with the teacher at the end of the day. In this way, the experiment
or demonstration can be repeated with other classes during other
years. We also offer to meet with the other teachers in the school
who are interested and show them the activities as well. The specific
teacher that we are working with acts as a resource person for the
other teachers. By working with the teachers, we expand the impact
of our program beyond the classrooms with which we meet directly.
For
the classroom activities we often draw on the wealth of ideas compiled
by other people, with modifications based on our own experiences.
In particular, we heavily use the "Universe at Your Fingertips,"
a large compendium of activities put together by the ASP's ASTRO
project. In addition, there are useful astronomy activities offered
by, for example, "GEMS: Great Explorations in Math & Science" (California,
Berkeley), the Optical Society of America, "Project SPICA: A Teacher
Resource to Enhance Astronomy Education," and "Ranger Rick's NatureScope
Astronomy Adventures" (National Wildlife Federation). As schools
and classrooms gain access to the Internet (as many expect to do
within one to two years), we will be able to draw directly on science
materials available on-line, such as the wonderful NASA pictures.
In addition, we try to pull material from our own research and that
of our colleagues at Lowell Observatory into the activities. For
example, when we do activities on comets, we show pictures of Hyakutake
and Hale-Bopp obtained for research purposes by Lowell staff. The
connection with an active research observatory adds an air of excitement-the
pictures we show may have been obtained just a few nights before
and the students may be among the first to view them.

In
the second year we added a new component to the program: bringing
the classes to Lowell Observatory to spend the night at two of our
research telescopes. The Perkins 1.8 meter and the Hall 1.1 meter
telescopes sit side by side on Anderson Mesa, a dark site southeast
of Flagstaff. We reserved nights on both of these telescopes with
a near-infrared camera on the 1.8 meter and an optical CCD camera
on the 1.1 meter. We also set up two small portable telescopes in
the compound and had another person showing constellations. The
students rotated from one station to another, in small groups. At
the two large telescopes they observed galaxies, studying their
morphology, and each group observed the same galaxies in the near-infrared
and in the optical.
This
program is focused on fifth through eighth grade classes. We chose
to work with a narrow grade range for two reasons. First, we wish
to work with students at a single rough conceptual development level.
According to an article by J. Bishop (see "Astronomy Learning and
Student Thinking," Mar/Apr 1996, p. 16), a teacher's effectiveness
is enhanced by tailoring instruction to what the children of that
age are able to comprehend. By working with students in approximately
the same stage of thinking, we can more easily learn how to present
ideas and how to work with the students on activities. Second, we
want to reach students at the transition period between the young
child's inherent curiosity about the world and the fixed negative
attitude towards science often seen in high school students. S.
Shuler, in a 1996 article in the Association of Women in Science
Magazine, made a plea for more emphasis on middle school science
education. She explains that during this stage science performance
for girls and minorities changes drastically, and it is at this
stage that one can have the most impact on their career options
and attitudes toward science.

OSU that the students used to study the morphology of galaxies.

We
are astronomers, not educators, and none of us has any formal educational
training. So, we are learning as we go along what we need to know
to make the program as effective as possible. In the summer of 1996
when we were shaping the plan for this program, we spoke with educators
and administrators to get their suggestions. In the first two years
we worked with teachers who have more astronomy background than
may be typical, so we could concentrate more on learning from them
how best to participate in the classroom. These teachers have been
very helpful in shaping the program. The teachers with whom we are
working joined us to attend the 1997 and 1998 ASTRO workshops in
Tucson, which helped us prepare for the school year.
Of
course, we are also learning from the students themselves. Hunter
and her teacher last year, Linda Doering, did an activity with Hopi
fifth graders based on making the Earth and Moon system out of modeling
clay. This requires that each group roll fifty equal-sized balls
from the clay, an activity that took much longer than expected.
Hunter was roaming from group to group, as she thought appropriate,
when one student said, "Why aren't you helping us?" Hunter looked
around and realized that Doering was helping each group in turn
by rolling balls herself. It just hadn't occurred to Hunter to participate
in that way.
Being
Aware of Cultural Differences
Going
to a reservation to do an outreach program is different in many
ways from going to your child's school, or even a school in your
own neighborhood. We are entering a culture that is unfamiliar to
us, and therefore we take the same care as when we visit a foreign
country.
One
of our initial concerns was whether or not the tribes would welcome
this program. Both the Navajo and Hopi nations are keenly interested
in improving their education in general and science education in
particular. However, imposed educational techniques have not always
been so positive for Native Americans in the past. A century ago
Navajo and Hopi children were forcibly taken from their families,
held in boarding schools many kilometers from home, and forbidden
to speak their language or practice their own culture. Because we
wanted our program to be something that the tribes saw as a positive
and desirable contribution to their schools, we solicited the opinions
and help of tribal members early on rather than developing the program
ourselves without this benefit. Therefore, when we were in the planning
stages of the program, we wrote to the tribal education departments
explaining our ideas for this program and seeking their input. This
led in turn to discussions with the Hopi Education Director and
a Navajo cultural education faculty member at the Navajo Community
College. During these meetings, we presented our ideas and received
from them suggestions on improvements, along with a great deal of
encouraging enthusiasm.
Differences
in culture can lead to a tremendous learning experience for everyone
involved, but such interactions must be approached with sensitivity
and an open mind. We recognized from the beginning that for our
program to be most effective we would need to deal with cultural
and background differences between the students and ourselves. We
talked with numerous helpful people who opened our eyes to new ways
of looking at things and of thinking, and through them we developed
a list of issues and concerns to address. We found that input from
the tribe, learning styles, language barriers, cultural connections,
and taboos were issues that we had to be aware of and plan for.
Usually they did not turn out to be major issues, but a little thought
and sensitivity ahead of time can keep them from turning into such.
Another complication comes from the fact that there are significant
cultural and language differences not only between the Navajo and
Hopi but also within each tribe. The Hopi at Second Mesa, for example,
have somewhat different traditions and dialect from those at First
Mesa, about thirty kilometers away. Thus, what we learn for one
group is not necessarily applicable to another.

grade class at Second Mesa Day School (Hopi Nation) pose with their

coma). The nucleus - is buried in the coma - cotton balls. Photo

In
1995 the American Indian Science and Engineering Society, with funding
from the National Science Foundation, produced a report whose conclusion
was that science educators need to use techniques appropriate to
Native Americans' learning styles. Differences in learning styles
arise because of cultural differences and the way in which children
are taught at home. Not all Native American cultures are alike,
of course, and what works well for one may not work well for another
group or individual. Furthermore, many of the principles of good
teaching work with most any cultural group, an example being the
desirability of hands-on activities over book-learning alone. But
the educator H. Gilliland in a 1995 book on teaching Native American
students emphasizes that Native American children tend to be more
visual learners. In fact, the English translation of the Navajo
word b%nabinтltее' implies both showing (demonstrating) and teaching
through showing. Thus, in our classroom activities we try to emphasize
visual aspects such as drawing and describing what students see.
Gilliland
also suggests that many Native American students learn best when
they work in cooperative groups rather than through individual competition,
and we have found that our teachers organize their classrooms this
way by arranging desks in small groups rather than the traditional
rows that emphasize the individual. This sense of cooperation does
not mean that one student won't sabotage another group's experiment
by filling their pan of flour with a handful of little rocks, as
we discovered during one activity. But it does mean that overall
this is a more receptive environment in which to carry out our classroom
activities.
For
some of our students English is a second language. According to
Linda Doering, in her fifth grade class roughly one-third can speak
the Hopi language, one-third can understand it, and one-third do
not know it at all. At this point we have not encountered a class
where language is itself a barrier, but Gilliland points out that
Native American students for whom English is a second language may
not know the nuances of the language such as multiple meanings of
words, even if they appear to speak English well. Thus, we are exploring
involving a translator in our classroom visits, and this may become
more necessary when we work with more remote schools. The issue
of language differences also means being more aware than usual of
our non-verbal communication and what our gestures, tone of voice,
and pattern of eye contact are conveying to the students.
To
help us deal with the language issue, we visited a Flagstaff classroom
with a large proportion of English-as-a-Second-Language (ESL) students.
The teacher suggested emphasizing visual techniques, writing short
notes on the board as one speaks, and avoiding terminology. With
the latter advice in mind, Hunter decided to stick to the basic
Moon phases (new, full, first quarter, last quarter) in one classroom
activity. As she and the students were moving their styrofoam balls
around their heads to simulate Moon phases, she didn't quite move
far enough before asking the students what the phase was. One student
promptly exclaimed, "A waning gibbous Moon." Lesson? Just because
there are potential language issues, don't underestimate your students.
Another
suggestion for ESL students was to not call on students because
they might not be able to articulate the answer. But, again, our
experience so far is different. Although eighth graders are more
reticent, as eighth graders generally are, in the fifth-grade classes
just about everyone volunteers all the time to answer regardless
of whether or not they know the answer. The only problem came after
an activity when students were asked to sum up what they had learned-then
there was dead silence. However, that may have had nothing to do
with languages.
Numerous
educators have expressed the need to make cultural connections in
order to make the learning activity more potent to the student.
After all, the Native Americans have been studying the skies for
millennia, and they have a rich heritage of knowledge and stories.
We ourselves do not know most of this traditional knowledge, but
even if we did, it is not our place to teach it. What we can do
is make collaborations with those who can. For example, at one star
party in Shiprock, we arranged for two people to attend who could
instruct the students about the Navajo constellations while we showed
them objects through our portable telescope. When rain drove us
inside to the library, our guests gave us a lecture on the Navajo
constellations and their associated stories. In another situation,
the teacher played a taped story about a frog and the Moon while
we rolled balls out of clay. Now we invite the students to teach
us about traditional knowledge by having them talk with their parents
and/or grandparents to learn sky stories, then teach them to us
in class. In this way they will make the cultural connections themselves.
Another
area of concern is taboos. For example, there are Navajo and Hopi
taboos against looking at the Moon and other astronomical objects,
potentially making star parties rather difficult. A star party is
okay with advance warning that allows for certain rituals before-hand
if desired, or by eliminating the Moon as an object to observe.
We have learned, too, that there are restrictions on when we can
hold star parties.

class at Chinle Middle School (Navajo Nation) look at galaxy images

Mesa in April 1998. Photo courtesy of Lowell Observatory.
For
the Hopi, December is a time to be indoors to listen to the traditional
stories, and so it is a bad month to hold a star party. For the
Navajo, traditional stories can't be told after the first thunder
in the spring, but a modern star party is acceptable. Not surprisingly,
in the desert southwest it is bad manners to speak ill of clouds
which could potentially bring much-needed rain. We must, therefore,
check our natural astronomer's inclination to lament clouds on nights
when star parties are scheduled. We learned this one the hard way-after
making several remarks about how we hoped the clouds would go away
so we could hold our star party that night, the teacher told us
to stop because the traditional stories say that the ancestors ascend
to the clouds after death. In effect, we were telling their ancestors
to leave. Not a very polite thing for a guest to do.
Stars
in Navajo and Hopi Traditional Knowledge
The
Hopi and Navajo have a long and rich history of astronomical observations.
Hopi tradition emphasizes the Sun (daawa), which is crucial to life,
as well as the Moon (muuyaw). The daily, monthly, and yearly cycles
of the Sun and Moon serve as a calendar to remind people when to
carry out the various activities that punctuate the day and year,
and the new year begins at the winter solstice (daawa gii awgbidu).
In addition to the Sun, each star (soohu) in the sky has a special
duty to perform. The Milky Way (soongwuga) is the gathering place
of the stars, and a shooting star or meteor (soohubosdoga) is seen
as a star that has fulfilled its purpose and fades away. One fallen
star or meteorite (soobosvu) created Meteor Crater (Yuvugbu) in
Arizona.
Navajo
tradition emphasizes the nighttime sky and the rules to live by
that one can find there. The many named constellations and stars,
as well as the Milky Way (Yikaisdáhí), are said to
have been carefully placed in the sky by Black God, while the countless
unnamed stars are the result of Coyote (Ma'ii), the trickster, grabbing
Black God's bag of stars and blowing the contents across the sky.
The carefully placed stars create patterns to guide humans, while
the stars scattered by Coyote represent the less orderly and unpredictable
aspects of life. Two major constellations are Revolving Male (Náhookos
bika'ii) and Revolving Female (Náhookos ba'áadii),
which are composed of the Big Dipper and part of Cassiopeia and
which revolve around the North Star. These constellations represent
a married couple that circle the fire in the center of their hogan,
a traditional home built with the doorway facing east.

from the Native Science Connections Project with us. Additional
material was taken from Book of the Hopi by Frank Waters and Living
the Sky: The Cosmos of the American Indian by Ray A. Williamson.
The
Future of the Program

Our
outreach program is modest and one of several operating in Navajo
and Hopi schools (others that we know of are run through Northern
Arizona University and NASA's Jet Propulsion Laboratory). However,
the response of the students and teachers to our visits convinces
us that our efforts are worthwhile. After one classroom visit about
the formation of impact craters, one Navajo eighth grader wrote,
"...who would of thought of how to explain craters to a bunch of
kids out on the reservation that may of not herd [sic] of different
star names and never herd [sic] of different moon names." Another
eighth grader wrote, "I really enjoyed having Dr. Hunter and Dr.
Bosh come to our class and teach us a lot about astronomy and how
much fun it looks like to be an astronomer." Many students referred
to the activities as "cool."

We
are grateful to Lowell Observatory and to NASA's IDEAS grant program
for the funding that enabled us to get this program going. We have
funding from AlliedSignal enabling the program to continue through
the 1998-1999 school year and partial funding for the 1999-2000
school year, and we hope that the program can be sustained indefinitely.
We know that we have a lot yet to learn and that the more we learn,
the more effective the program will become. The important point
is for us to recognize that science education is not separate from
other aspects of the students' lives and to be aware of the consequences
of cultural differences. We have to remember that this program is
really an information exchange. We tell them about astronomy and
science; they teach us about their culture. An enriching experience
for all involved, hopefully. Certainly it is for us.
