Is the MSDS Sheet a useful document for a chemistry teacher?

Tue, 11/25/2014 - 16:24 -- Bob Worley

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?

Conceptual Chemistry

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.

Photoelectron Spectroscopy Special Issue Article

Mon, 10/27/2014 - 17:58 -- Deanna Cullen

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.

Scientific Practices Post #2: Conclusions from Evidence

Tue, 10/21/2014 - 11:21 -- Shelly Belleau

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 Standards (a centralized them

Simple Activities to Integrate Particle-Level Diagrams

Mon, 10/20/2014 - 08:34 -- Erica Posthuma-Adams

There have been many conversations within the Chemistry Education community surrounding the revisions to the AP curriculum. Twitter has been buzzing with instructors debating how to implement the changes, conferences and workshops have participants deconstructing the data from last year’s exam, and classroom teachers are working diligently to prepare their students for this year’s test.

One way the College Board has tried to shift the AP curriculum away from algorithmic problem solving and toward more meaningful conceptual understanding is through the use of particle diagrams.
