The old way of teaching science would have had Denver science teacher Melissa Campanella giving a lecture on particle collisions, then handing her students a lab that felt a bit like following a recipe from a cookbook.
Now she starts the same lesson by activating glow sticks, one in hot water, the other in cold. Her students at Noel Community Arts School make observations, brainstorm what might cause the differences they detect, come up with models and visual diagrams that map those ideas, share those models with each other, revise, read about the collision model of reactions, and revise again.
“Before, they would maybe know basic ideas from memorization, and maybe they would retain this information long enough for me to give a quiz on it,” Campanella said. “Now they have a better understanding of why those fundamental rules exist, and because they drew those conclusions themselves, they remember it better.”
This is the future of science education as envisioned by the scientists and educators who developed the Next Generation Science Standards. A committee working to revise Colorado’s science standards has recommended we adopt a modified version of them. Because Colorado has local control, individual school districts will still be responsible for their own curriculum, but the standards will lay out what students are expected to know at each grade level.
These science standards are part of the same sweeping philosophical shift in how we teach that brought us the Common Core math and reading standards, and provoke some of the same tension about what’s more important: knowing a thing or knowing how we know it? At the same time, the website promoting the Next Generation standards takes great care to say these are not part of the Common Core standards, which have become heavily politicized and are often seen as an example of federal overreach.
Colorado’s State Board of Education, the science standards review committee, and the state’s science teachers will have to navigate this terrain between now and this summer, when the new standards need to be finalized — and then for years to come as they’re implemented in Colorado classrooms.
