Students in one of LA's hottest neighborhoods are transforming from passive learners to active researchers through experiential education
Imagine touching your neighborhood playground on a summer afternoon and feeling not just warmth, but dangerous, skin-scorching heat. For students in Pacoima, California, this isn't just an imagination—it's their daily reality.
Located in the San Fernando Valley, Pacoima consistently ranks among the hottest areas in the Los Angeles region, with dark asphalt surfaces absorbing solar radiation and transforming the community into an urban heat island.
Rather than simply learning about this challenge from textbooks, Pacoima students are experiencing science firsthand through a revolutionary approach called experiential learning, connecting classroom concepts to real-world solutions.
Experiential learning "invites students to engage directly with the world—solving problems, working collaboratively, and drawing conclusions from their own experiences" 4 .
At its core, experiential learning is an educational approach that positions students as active participants rather than passive recipients of information. Rather than simply memorizing facts, students engage in direct experiences followed by critical reflection. This method creates deeper connections to knowledge and more lasting understanding 4 .
"Learning is the process whereby knowledge is created through the transformation of experience" 8 .
Engaging in an actual activity or task
Stepping back to review and reflect on what occurred
Developing understanding and theories about the experience
Applying new knowledge to different situations

As an urban heat island, Pacoima experiences temperatures significantly higher than surrounding rural areas—a phenomenon with serious implications for public health, energy consumption, and community livability.
In June and July of 2022, Pacoima became the focus of a major scientific investigation when the GAF Cool Community Project treated over 700,000 square feet of dark asphalt surfaces with a special reflective coating called DuraShield-SR 5 .
Maximum ambient air temperature reduction observed
| Scale of Measurement | Impact Observed | Significance |
|---|---|---|
| Surface Temperature | Substantial reduction | Directly reduces heat absorption and storage |
| Pedestrian-Level Air | Up to 3.5°F reduction during extreme heat | Improves thermal comfort and public health |
| Urban Canopy Layer | 25-50% reduction in UHI effect during peaks | Community-scale climate modification |
Critical findings showed that the cooling benefits resulted primarily from enhanced near-infrared reflectance rather than changes in the visible spectrum, explaining why the coatings could reduce temperatures without creating visual discomfort 5 .
Visible spectrum reflectance increased only modestly, from 0.08-0.10 to 0.12-0.15, a change determined insufficient to cause visual discomfort or glare issues 5 .

Understanding how researchers study urban heat islands requires familiarity with their specialized tools. The Pacoima study employed an array of sophisticated instruments, each serving specific functions in data collection 5 .
This highly portable, field-deployable instrument measures surface reflectance across multiple spectral bands (UV, visible, and near-infrared). Its compact design enables rapid data collection at various locations, allowing researchers to verify reflectance changes immediately after coating application 5 .
Flying over the project area during specified intervals, this aircraft captured snapshot thermal imagery using advanced hyperspectral thermal sensors. The aerial perspective enabled researchers to analyze spatial patterns of temperature distribution across the community 5 .
Researchers outfitted an electric golf cart with precise meteorological sensors to continuously measure temperature variations. The electric platform prevented exhaust heat from contaminating measurements, while its slow speed allowed for detailed pedestrian-level data collection 5 .
Mounted on city street lighting poles in both test and reference areas, these stations provided continuous monitoring of above-canopy background conditions. This allowed researchers to verify that temperature differences resulted from the pavement coatings 5 .
For students learning about scientific methodology, this diverse toolkit demonstrated that addressing complex environmental questions often requires multiple measurement approaches and cross-validation between different data sources.
The Pacoima cool pavement initiative provides a powerful model for how real-world scientific research can create meaningful experiential learning opportunities for students. By engaging with actual community challenges, students transition from passive observers to active participants in the scientific process.
In experiential learning frameworks, activities like analyzing thermal imagery, conducting surface temperature measurements, and comparing reflectance data become concrete experiences that form the foundation for learning cycles 4 .
"Experiential learning is an educational approach built around active involvement, reflection, and personal meaning-making" 4 .
The Pacoima case study demonstrates how community science initiatives can serve as living laboratories where students develop not only scientific knowledge but also critical thinking skills, data literacy, and civic engagement.
The story of Pacoima's cool pavements represents more than just an innovative approach to urban heat mitigation—it illustrates a transformative educational methodology.
The scientific results from Pacoima offer promising insights for communities worldwide struggling with rising temperatures. The demonstration that reflectively coated surfaces can significantly reduce urban heat without negative consequences provides cities with a practical tool for climate adaptation 5 .
As educational paradigms continue evolving toward more engaged, student-centered approaches, the integration of genuine research experiences into curriculum offers a pathway to deeper learning and enhanced scientific literacy.
In Pacoima, that transformation is happening daily—as students experience firsthand how scientific inquiry can make their community cooler, healthier, and more sustainable.
