About 18 states have adopted the Next Generation Science Standards. And although these shared science expectations have been out for about five years, testing models that fully capture students’ grasp of them have lagged far behind. (So far, only a handful of states have updated their science tests to match.)
The NGSS poses some big technical challenges for the smarty-pants who develop student tests. For one, the NGSS expects students to learn primarily by interacting with phenomena and recording and analyzing data. That’s basically the inverse of how most of us learned science, in which a teacher explained a new concept and, if we were lucky, illustrated it through a lab.
New tests also needs to match the standards’ crosscutting concepts, such as being able to recognize patterns and understand scale and proportion.
Now, the American Association for the Advancement of Science has begun a new project to craft model test items related to the standards’ energy practices.
