July 29, 2002 NM TEACHERS FOCUS ON GEOGRAPHIC POSITIONING, UV MEASUREMENTS Priscilla King, a science teacher at Navajo Pine, was one of the New
Mexico teachers who recently participated in the Math and Science Teacher
Academy at the University of New Mexico's College of Education. They just
completed the final summer of a two-year commitment in the academy. King, and the other middle and high school teachers from communities
statewide, was provided with laptop computers to collect and store data,
GPS (global positioning system) units and UV (ultraviolet) meters. They
learned to use the equipment and have developed projects in their classrooms
using it. "Using the GPS unit, the students learned how to pinpoint latitude and longitude on a map. I created a scavenger hunt for the students where I hid candy at specific locations they had to find," King says. The students also learned about differences in elevation. "At Navajo
Pine, we're at 7,000 feet. Farmington is at 5,000 feet. I talked to them
about the thinner air at the higher altitude and we discussed how the
body reacts to the change in altitude." The UV meter, Sun Safe, is a handheld device that gives an instant read.
The students record the data at 9 a.m., noon and 3 p.m. Not only are they
learning about peak times for UV radiation exposure, but they also learn
about the scientific method and create spreadsheets to demonstrate findings.
King's students conducted the UV readings, but also learned something
about the ways their Navajo ancestors have traditionally protected themselves
from the sun. "The Navajo people developed their own sunscreen out
of red ochre and sheep tallow. They would put it on when they went out
shepherding," says King. She says that the sunscreen, called 'chi'i''
has been tested for its effectiveness in blocking UV rays. "The ochre
forms a barrier from the rays and the tallow keeps it from being sweated
off," she says. "Navajos' awareness of the dangers of the sun goes way back. They
wear long sleeves and don't expose the body to the sun," she says.
Next year she plans to have the students conduct a study comparing the
effectiveness of chi'i' with commercial sunscreens. Additionally, she
shared general information about cancer with her students by relating
it to the experiences of the uranium mine workers. "New Mexico has high melanoma rates and we recognize the need to
educate children about the long term affects of early sun damage. Cancer
may not show up for 20 or 30 years after exposure. Many adults may use
sunscreens, but may not be encouraging use among children," says
Anna Wilder-O'Neil, a doctoral candidate in Multicultural Teacher and
Childhood Education. Wilder-O'Neil works with Teresa Kokoski, coordinator
of the Mathematics, Science, Environment and Technology Program to develop
and offer the academy. "The teachers can use the tool to bring out information from the
data they have. They can conduct site analyses and understand the correlation
between the geography of their region and UV exposure," says Kokoski.
She says that the 27 teachers enrolled in the program represent a range
of experience, from those with no computer experience to those teaching
computer science. "It's their interest and motivation in bringing
this technology into the classroom that makes the program work,"
Kokoski says. The training also counts toward the teachers' professional
development. King, who earned a master's in education from the University of New Mexico
and has taken courses toward a master's in science teaching from New Mexico
Tech, teaches biology II, environmental science and chemistry. She says,
"We would not have had access to the technology and training without
the Science Academy. I learned a lot from the facilitators and also through
sharing with the other teachers enrolled in the program." Some of the teachers will present their work at the National Science
Teachers Association conference, to be held in Albuquerque in December. ### |
