Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

A key aspect of learning in K-12 education is the idea that what students know and are able to do grows and evolves over time. Simple ideas learned in the early elementary grades gain levels of detail and complexity as students progress in their education. Connections between different topics and disciplines are made.
