* Extend the aforementioned to describe (qualitatively) energy levels within multi-electron atoms, resulting spectra, and the production of light in a laser
* Board presentation with notes and examples
* Multiple representations (graphical and algebraic)
* One-on-one teacher / student instruction during practice session
* Peer teaching / collaboration during practice session
* Class discussion with inquiry method
* Monitor proficiency during practice session
* Call on students at random or with emphasis on students who may need assistance
* Assign pre-class problem(s) on next day after practice / reflection homework assignment
* ActivBoard and chalkboard
* Representative AP Problems
* Pre - Read / Outline Sections 29.5-29.9
