Show Me the Stoichiometry! When the Next Generation Science Standards (NGSS) were made public several years ago, some in the chemistry education community pointed out the lack of performance expectations (PEs) based on traditional chemistry topics, like stoichiometry, but a close reading reveals a number of ways in which such topics may be integrated into an NGSS-based chemistry curriculum.
The Next Generation Science Standards (NGSS) promote a science education framework that forefronts the practice of science and uses three dimensions that ask students to assume a more autonomous role in their learning.
Our natural world is filled with explorable phenomena that can serve as the gateway to meaning science teaching and learning. Read about five characteristics of phenomena and how engaging students in them will them think like scientists!
