Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

It is this messiness that both deters potential users of authentic data and gives data the power to create unique learning opportunities that reveal the nature of science…

Current science education reforms and the new standards (Next Generation Science Standards [NGSS], 2013) advocate that K-12 students gain proficiency in the knowledge-generating practices of scientists. These practices include argumentation, modeling, and coordinating evidence with theories and models. Practice-based instruction is very different…
