Do Berkeley school gardens get an A or a C for motivating kids?
Photo: Edible SchoolyardSupporters of school gardens were positively giddy last week over news that a three-year UC Berkeley study of a garden and cooking initiative in Berkeley, Calif., schools had shown that it made students more eager to eat vegetables and choose healthy food.
Berkeley restaurateur Alice Waters, through her Chez Panisse Foundation, has done pioneering work and invested considerable funds in the idea that children exposed to gardening and cooking will develop healthier eating habits. According to researchers at the university’s Dr. Robert C. and Veronica Atkins Center for Weight and Health, fourth- and fifth-graders in her “highly developed” garden and culinary program increased their consumption of vegetables by nearly one serving per day.
But a closer look at the report reveals that as students moved into middle school, they not only made little further progress, but they actually regressed — even though they spent more time in gardening and cooking classes.
The findings are sobering for the edible school garden movement, indicating as they do the extraordinary resources that had to be put into play to achieve mixed results. For thousands of educators and parents pinning great hopes for children’s health on a school garden of their own — struggling to put a garden in place with little funding or support from school administrations, struggling to keep it going with no paid staff and unreliable volunteers — the notion that success depends on having a full-time gardener (or three), a paid cooking instructor, dedicated kitchen facilities and a revamped curriculum to go with meals made from scratch in the cafeteria, has to be a bit daunting, even while it validates Waters’ years of unflagging work in the field.
Sowing the delicious revolution
Berkeley schools are in the fifth year of a major food-service overhaul instigated by parents with help from the Chez Panisse Foundation and the nonprofit Center for Ecoliteracy. The schools eliminated processed, reheated meals and adopted food made from scratch. A local bond initiative helped pay for a new central kitchen. Meanwhile, the School Lunch Initiative, designed to teach children the connection between how food is grown and prepared and their own health, installed gardens in all 11 of the district’s elementary schools and three middle schools. Thirteen instructional kitchens were built.
Waters’ vision of children growing and cooking their own food has inspired school gardens across the country. The perceived benefits have been the subject of sometimes furious debate.
The researchers reported that there was wide variation in how Berkeley schools rolled out the School Lunch Initiative. They also said it was difficult to establish a control group for their study with which to measure results.
So what they did was to divide Berkeley schools into two groups, one described as having a “highly developed” garden, cooking, and nutrition education program, and the other having a “less developed” program. We’ll call these groups HD kids and LD. They selected two elementary schools in each group and began tracking the progress of fourth- and fifth-graders using questionnaires and photographs of what the kids chose for lunch.
The two LD schools, represented by 193 fourth- and fifth-graders, had no paid garden staff, little to no garden programming, and students who spent little or no time in the garden. In addition, these two schools had no paid cooking staff and no cooking classroom, and teachers in the school had done little to integrate nutrition lessons into the curriculum. These schools tended to have larger proportions of students from higher-income families and were thus ineligible for outside funding to pay for enhanced programs.
In contrast, the two HD elementary schools, represented by 134 fourth- and fifth-graders, had paid garden and cooking staff, and the students spent 22 to 56 hours in garden and cooking classes each year. In addition, some teachers had integrated nutrition into the curriculum. These schools tended to have higher proportions of low-income students and were thus eligible for outside funding to pay for enhanced programs.
All three of the middle schools that these students eventually attended for sixth and/or seventh grade had garden and cooking programs in place, although some programs were more advanced than others. At the Edible Schoolyard run by the Chez Panisse Foundation at Martin Luther King Jr. Middle School, for instance, several people are employed to maintain and give instruction in the garden, and a kitchen is lavishly equipped with an instructor and volunteers, individual workstations with a full complement of cooking tools, four cooktops with sinks, a free-standing convection oven, and a commercial-grade dishwashing system.
Following the students from these four schools over a three-year period yielded these results:
