Next Generation Science Standards are coming fast. Public comment on draft 2.0 just ended. The final version is due out in March. Then states will be urged to adopt NGSS, as most did Common Core State Standards in English and math. It’s too soon, advises Fordham, which has been reviewing state science standards for years. ”This important, ambitious, but still seriously troubled document” needs more work, write Checker Finn and Kathleen Porter-Magee.
In an effort to draft “fewer and clearer” standards to guide curriculum and instruction, NGSS 2.0 (like NGSS 1.0) omits quite a lot of essential content. Among the most egregious omissions are most of chemistry; thermodynamics; electrical circuits; physiology; minerals and rocks; the layered Earth; the essentials of biological chemistry and biochemical genetics; and at least the descriptive elements of developmental biology.
. . . Real science invariably blends content knowledge with core ideas, “crosscutting” concepts, and various practices, activities, or applications. . . . (But) authors have forced practices on every expectation, even when they confuse more than clarify. For example, high school students are asked to “critically read scientific literature and produce scientific writing and/or oral presentations that communicate how DNA sequences determine the structure and function of proteins, which carry out most of the work of the cell.” Here as elsewhere, the understanding of critical content—which should be the ultimate goal of science education—becomes secondary to arbitrary and peripheral activities such as “critical reading” and “oral presentation.”
Appendices explain “what is and isn’t present and why,” but the structure is “complex and unwieldy,” Finn and Porter-Magee write. “Will a fifth-grade teacher actually make her way to Appendix K to obtain additional (and valuable) information about science-math alignment and some pedagogically useful examples?”
Science students won’t have to learn much math, leading to “dumbing down,” especially in physics, they fear. And the “assessment boundaries” will ensure that students aren’t challenged.
The new standards don’t require chemistry labs, complains Harry Keller, a chemist. The word “chemistry” is never used, though “chemical reactions” can be found under physical sciences. Without labs.
Physicists also are dissatisfied, reports Ed Week.
