I came across a very interesting study Teaching Multivariational Reasoning through AI-Guided Inquiry in Interactive Simulations Ekaterina Shved, Engin Bumbacher, Seyed Parsa Neshaei and Tanja Käser from EPFL in Lausanne Switzerland
I and all of us at the Let’s Think Forum have been deeply interested in the thinking schema of variables for decades. I thought the main findings, even though they were used in an AI tutoring environment could be translated into Cognitive Acceleration through Science Education (CASE) style lessons. These are my efforts at translating this research to inform our practice.
The recent research explored teaching two different strategies using interactive simulations. The first was named by the researchers as CVS++. This extends the classic control-of-variables strategy by having students isolate individual variables and then combine them using proportional steps.
The second is the General Principle Strategy (GPS), where students vary multiple variables simultaneously to find different combinations that produce the exact same outcome.
The findings are highly relevant for our classrooms. Learning the step-by-step CVS++ method gives students an immediate boost in understanding single-variable effects. However, the long-term secret to student success isn’t strict adherence to one specific formula. When students face brand new contexts or simulations, rigid strategy use naturally declines. Instead, the research reveals that the highest-performing students are those who consistently engage in systematic inquiry cycles—coordinating their exploration, recording, and analysis actions.
So, how can you apply these findings in your early secondary face-to-face science classes? My thoughts
