The Research Supports Project-Based Learning
Since 2000, researchers have consistently found that PBL increases learner mastery, retention, rigor, and problem-solving abilities. Defined is built on that foundation.

What the Research Shows
Independent studies of Defined's approach demonstrate consistent, measurable gains across student populations and subject areas.
Students in PBL Outperform Their Peers
An independent study showed students in a Defined PBL environment outperformed non-PBL classes at every grade level in both reading and mathematics.
Stronger Engagement & Critical Thinking
A Mida Learning Technologies study showed measurable improvements in student engagement after one year with Defined — including gains in critical thinking and problem-solving.
Results for English Language Learners
A Stanford University study of sixth-grade classrooms showed ELL students scored up to 28 percentage points higher on language proficiency tests in PBL environments.
Social Studies Achievement
Second graders in low-socioeconomic-status schools demonstrated a 63% gain in social studies learning when engaged in project-based units.
Advanced Placement Performance
Schools using PBL approaches saw a 10 percentage-point increase on AP exam scores — demonstrating that deeper learning prepares students for rigorous academic challenges.
Cross-Subject Impact
Sixth-grade math and science scores both improved in PBL classrooms, showing that career-connected projects reinforce academic learning across disciplines.
Rooted in Understanding by Design
In 2014, Defined partnered with Jay McTighe — co-creator of Understanding by Design (UbD) — to ground our entire platform in evidence-based pedagogy. Every performance task and project reflects the backwards design principles that decades of research show lead to deeper, more durable learning.
