Xperience ChemEd X

(e)Xperience ChemEd X through the ideas and opinions of its community members.

Xperience is where contributed, but not reviewed, ChemEd X resources such as blogs and opinion pieces are found. Here you can find blogs in which our contributors express their personal empiricism and polls in which you the community can provide your opinions.

Happy New Year!  Did you know that 2015 is the International Year of Light (IYL)? IYL is a “global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health1”.  IYL is sponsored by several organizations with interests in science and science education, including the European Physical Society, the Institute of Physics, the American Physical Society, and the American Institute of Physics.  You can find several lesson plans, videos and other educational resources on the IYL website2.

Whenever a serious incident takes place in a school chemistry laboratory or classroom, fire and safety officers often pontificate on the incident by quoting the Materials Safety Data Sheet (MSDS). However, how many of you have read such documents in full? In UK schools we have perhaps 200 to 400 chemicals on the shelves. Have you read the MSDSs for each chemical?

TV and movie screens today offer us a desperate fight against crazy-fast zombies, a peek into celebrities’ lives where truth is often stranger than fiction, million-dollar game shows, and more. Can portraits of science compete?

In a recent contribution to ChemEd X "Stoichiometry is Easy", the author states that he has "vacillated over the years between using an algorithmic method, and an inquiry-based approach to teaching stoichiometry. " I would like to suggest that there is another approach to mastering stoichiometry and that it should precede the algorithmic one: it is the conceptual approach based on a particle model to represent the species involved in chemical reactions.

The new AP Chemistry curriculum is in the second year of use. Photoelectron spectroscopy (PES) is a topic that generated much discussion because it is an addition to the curriculum. Jamie Benigna of Michigan teaches AP Chemistry, is an AP reader and recently wrote an article about PES for the Journal of Chemistry Education Special Issue. The article discusses the rationale for including PES in the course, explains some background of PES and provides strategies for including PES in your own course. This article is offered as a free preview of the AP Special Issue.

In this post I would like us to consider the ways teachers can help support and scaffold the process of making claims and drawing conclusions on the basis of evidence.  Not only is this grounded in the scientific practices addressed in the Next Generation Science Standard
