The ADI Instructional Model
We create hands-on programs for science, math, and engineering that help students learn by doing. Every investigation or design challenge is built around a meaningful question or real-world problem. As students work through each task, they use what they know about STEM to figure something out or design a solution.
​
Along the way, students build essential literacy skills—reading to gather and evaluate information, talking to share and refine ideas, and writing to explain what they figured out.
All of our materials are built using the Argument-Driven Inquiry (ADI) instructional model. This model is grounded in classroom-based research and shaped by real feedback from teachers to make learning more effective—and more engaging—for everyone.
The ADI Model for Science
Science is about figuring out how or why something happens—and that’s exactly what students do in our investigations. Whether they’re exploring plant growth in kindergarten or analyzing evidence from a chemical reaction in high school, students learn science by doing science.
Our approach gives students meaningful opportunities to explore core ideas, apply crosscutting concepts, and use science and engineering practices to make sense of the world around them. Each investigation encourages students to read, talk, and write like real scientists.
​
Hundreds of investigations and three-dimensional assessments can be found in the ADI Learning Hub, or you can choose to buy a book that includes 8 ready-to-use science investigations for your grade level.
The ADI Model for Engineering
Engineering is about solving real problems—and that’s exactly what students do in our design challenges. Each challenge gives students a chance to apply what they know about science, math, and engineering to develop creative, evidence-based solutions.
​
Students work through meaningful tasks that explore topics like energy, forces and motion, matter, ecosystems, and the impact of human activity. Along the way, they build critical thinking, collaboration, and communication skills.
​
All of our design challenges can be found in the ADI Learning Hub. They’re perfect for acceleration, STEM camps, enrichment, or use in an engineering or science class.
The ADI Model for math
Math is about making sense of patterns, relationships, and real-world problems—and our investigations help students do just that. Each task invites students to explore a concept, use reasoning to solve problems, and communicate their thinking clearly.
​
Middle school investigations focus on topics like the number system, proportional relationships, expressions, geometry, and statistics. High school investigations dive deeper into algebra, functions, geometry, probability, and more.
​
All of our math investigations are available in the ADI Learning Hub and are designed to be used alongside your core math curriculum to deepen understanding and build problem-solving skills.
