This summer, around 30 middle-school students from the Tennessee Nature Academy explored upstream and downstream Mill Creek, which flows 28 miles from Nolensville to the Cumberland River in Tennessee. Some students moved as quickly as algae-covered rocks would allow, while others took cautious steps; all of them shared the āLet-me-seeā mindset encouraged by , who leads the summer camp and research study.
āA lot of STEM curriculum designing for kids focuses on ācan-I-be spaces.ā āCan I be a scientist?ā āCan I do this experiment?ā It introduces kids to established cultures and scientific language and practices, which is important, but that funnels them into a way of being,ā said Carlone, professor of teaching and learning and the Katherine Johnson Chair in Science Education at 91ĢĘ²®»¢ of education and human development. āWhat happens if we put them in ālet-me-seeā spaces? āLet me see if I can discover where the crayfish live. Let me see if I can interview a scientist about an idea I have.ā We tell kids, āTry it out. See what you think.āā
This mindset supports what Carlone calls āhorizon-expanding spaces,ā where middle school students can explore STEM and other academic identities in a more fluid, developmentally authentic way. āAt this age, kids move in and out of deciding who they are every day, so we wanted to design curriculum that reflects how they learn about and develop their STEM identities,ā Carlone said.
In 2023, she began leading an interdisciplinary study with co-PIs , research assistant professor of earth and environmental sciences and director of research initiatives at Peabody College, and , assistant professor of earth and environmental sciences. They wanted to understand whether and how place-based learning and STEM identity play supports youthsā engagement and development in STEM.
Even though the students in this yearās three-week camp were from Tennessee Nature Academy, and therefore well versed in outdoor STEM learning, by the end of the camp, almost all of them expressed that the experience expanded their sense of belonging in STEM and what they believed they could accomplish.
A camper named Brax shared how scientific investigations inspired their appreciation for the creekās diverse ecosystem. āMeasuring pH levels, dissolved oxygen, and temperatures changed the way I think about the creek because it showed how a creek is home to many different animals and ecosystems,ā Brax said.
Another camper named Kariany took pride in her newfound sense of altruism. āAt first, I felt disgust [in the creek], but now, [I know that] weāre basically helping nature,ā Kariany said. āI would want people to know that itās gonna be scary at first, youāre gonna struggle a lot, but itās going to be worth it because youāre going to feel helpful.ā
Five dimensions of place-based learning
The campās support of studentsā STEM self-concepts reflects the studyās five dimensions of place-based learning:
- Connection: The research team introduced the students to transdisciplinary science to connect them to their communities and each other as they learned about Mill Creekās history, geography, and social and ecological significance.
-
TReCS campers cleaning up Mill Creek Investigation: The students explored the creekās depth, width, and ecological health, as well as how communities use land in the watershed. Along with community members, they cleaned up 425 pounds of litter.
-
TReCS campers studying the map of Mill Creek Interrogation: The campers critically analyzed the socio-ecological connections in the watershed to understand which neighborhoods have access to clean parts of the creek and which are exposed to littered parts, which neighborhoods experience flooding, and how land use affects water quality from upstream to downstream.
-
Campers interviewing Urban Green Lab representative Imagination: To develop their agency in supporting the creek, the kids interacted with adults who care for the creek and the socio-ecological health of the watershed. For example, farmers working with taught the campers about regenerative farming. They also engaged with members of , a councilperson committed to Mill Creekās health, and Tolani Abari, a local 11-year-old environmental advocate. The campers then imagined possible futures for Mill Creek and its watershed, and rendered these stories in the form of podcasts, augmented reality, and zines (a pamphlet-like publication).
- Action: Following the camp, the students presented their designs at a exhibit on July 1. The act of storytelling for a live audience allowed the students to express agency over their environmental concerns.
Student agency on display at the Curb Center
The studentsā presentations at the Curb Center exhibit reflected their range of emotions about socio-ecological thriving and their determination to strategically plan for Mill Creekās future.
Two campers, Claudio and Matthew, interviewed , MSNā06, DNPā12, professor at the School of Nursing, in a about āgrounding,ā a therapeutic technique of immersing oneās feet in the soil, which she shared with them during a camp presentation along Mill Creek. Following the interview, they walked podcast listeners through a grounding meditation at the creek. , one of the campās teachers and a Native American woodland style flutist, played ambient flute music in the background.
A student named Carley Gray presented a zine project that imagined utopian and dystopian futures for Mill Creek. The dystopian renderings allowed Gray to express her anxiety about the future of environmental sustainability. āOver the course of three weeks, I learned more about myself than I knew starting camp,ā Gray said. āI realized I actually kind of am a futurist. I am a creative.ā
Using augmented reality, another group created 3D renderings of an improved site at The Global Mall in Nashville, formerly the Hickory Hollow shopping district. It is now a mixed-use building for public spaces, such as a branch of the Nashville Public library and a satellite campus for Nashville State Community College. The studentsā designs of a rain garden and greenspace plaza were mindful of the socio-ecological needs of the community and informed by their study of the mallās history, the for the mall, and interviews with visitors.
Affirming STEM identities
Throughout the camp, the research team and camp counselors honored studentsā participation with STEM āidenti-badgesā that conveyed how the team viewed each camperās STEM identity development. The badges affiliated students with around 40 unique STEM professions and self-concepts, including as hydrologists, animal empaths, water chemists, and creek caretakers.
As meaningful as the badges were, Carlone said the āidenti-beadsā meant more to the students because they selected the beads themselves, which allowed them to narrate how they saw their STEM identities form and develop throughout the camp.
āPart of curriculum designing for identity play is to provide kids the opportunity to narrate their participation and modes of engagement throughout the camp, whether thatās as an investigator, connector, tinkerer, environmental advocate, etcetera,ā Carlone said.
She recalled the excitement of one student in selecting their identi-beads who said, āWe donāt usually get to acknowledge ourselves in this way. Weāre used to other people labeling us.ā
Each camper selected multiple identi-beads, reflectingāmuch like the movement of Mill Creek itselfāthe fluidity of adolescent STEM identifications and ambitions.
