Push to improve K-12 education takes root in local high school's backyard
"To the left," high school senior Jovanni Martinez called out to his principal, Marshall Burgamy, who was scrambling on all fours through a thicket of shrubs while clasping one end of a length of transect tape. The pair was attempting to lay a straight, 50-meter course for a vegetation analysis at Jasper Ridge Biological Preserve.
Also on hands and knees in the dirt, Rodolfo Dirzo, professor of biology at Stanford, emerged from the same patch of shrubbery, where he had been working side-by-side with three of Martinez's classmates.
Martinez is one of approximately 30 teenagers enrolled in the Redwood Environmental Academy of Leadership (REAL), a Stanford University-funded program that holds classes twice a week at Redwood High Schoolthe only continuation campus in the Sequoia Union High School Districtin Redwood City. The Jasper Ridge vegetation analysis is one portion of a special field trip that the four teens participated in that day.
Later that afternoon, the group analyzed the data in a classroom at the preserve, located just west of the Stanford campus. With the help of a Redwood High math teacher and two Jasper Ridge docents, the students calculated the density, frequency, dominance and value of importance of each species of plant they had encountered.
"They're really learning the concepts of ecology," said Dirzo, the Bing Professor in Environmental Science and one of the program's founders, "but by doing activities, by doing the work of scientists themselves."
"Learning by doing is key when you have students that have really never had a successful scientific experience or class," added Cindy Wilber, the education coordinator at Jasper Ridge and REAL's other founder.
The program, now nearing the end of its first year, is funded by a grant from the Stanford University Initiative on Improving K-12 Education, one of the multidisciplinary initiatives sponsored by the university's $4.3 billion fundraising campaign, The Stanford Challenge. Dirzo and Wilber co-wrote a grant proposal, in collaboration with Burgamy, and theirs was one of eight pilot projects accepted for the K-12 initiative's first round of funding for the 2008-09 year.
"I am humbled that they [Dirzo and Wilber] have taken invaluable time out of their many important responsibilities to plan, implement and collaborate for countless hours on this small high school program for underserved kids," Burgamy said. About 70 percent of the students are Latino, 40 percent are English-language learners and 70 percent are from low-income households, according to Burgamy.
REAL takes place on a plot of land behind Redwood High that is about as big as a football field. To get there, participants cross a bridge over Cordilleras Creek, which runs adjacent to the school and represents the heart of the program. The teens study how the creek fits into the ecosystem in a broader context, how development has changed the creek ecosystem over the years and what the students' responsibilities are as environmental stewards of the creek.
A garden, currently dominated by weeds, occupies a large portion of the land. Classes take place on a small patio or in an adjacent shed that serves as the students' laboratory. Nearby is a small greenhouse.
The curriculum is organized into three-week modules that focus on topics such as species interaction or ecosystem services. Dirzo lectures on species interactionsthe ecological relationships of plants and animals. Specifically, he covers how these interactions determine plant fitness and influence evolution. Students then come up with their own examples of species interactions with which they are familiar.
During a different session on ecosystem services, Redwood High history teacher Maureen Svenson asked the students to study old maps of Redwood City to see how development had changed the land. Then, the studentspretending to be landscape designers themselveswalked the land and created development plans that they would later present to their classmates.
has really made me look at the curriculum and come up with things that are much more interdisciplinary than I [otherwise] would have," Svenson said. "It's been a really creative exercise for me."
Dirzo stressed that being a part of the Stanford K-12 initiative's grant program has been instrumental in fostering interdisciplinary collaborations.
For example, fellow grant-winner philosophy Professor Rega Wood of Stanford and graduate student Eva St. Claire helped design a lesson plan about the use of Latin in scientific vocabulary, in order to help REAL students understand the words they encounter in class.
Thanks to another collaboration with grant-winner Professor Roy Pea in Stanford's School of Education, REAL will soon be international. Via the Internet, Skype calls and YouTube videos, Redwood High students will correspond and share data with students in Sweden and with participants of similar restoration projects that Dirzo and Wilber lead in Mexico.
"This will connect students doing ecology across the globe, from Redwood City and Yucatan to the state of Veracruz and Sweden," Wilber said.
She and Dirzo plan to continue the program beyond the pilot phase and are applying for additional funding.
