Gas Laws and the Over-Reliance on Algorithmic Thinking

As our Gas Laws unit was coming to an end, it was time to create the test. As I thought of potential test questions that were both challenging and in alignment with the learning objectives we had previously identified for the unit, I was reminded of a multiple-choice question I had been shown in an old Modeling InstructionTM resource.

Nominate Outstanding High School Chemistry Teachers

ACS Regional Award for HS Teaching

In 2006, The Division of Chemical Education endowed an award program, the Regional Award for Excellence in High School Teaching, to recognize and inspire outstanding high school chemistry teachers. Each of the ten Regions of the American Chemical Society solicits nominations for this award. The winners receive $1000, an engraved plaque and travel expenses to the meeting where they are honored.

Especially JCE: March 2017

Throw the phrase “chemistry class” at someone to get their reaction. What do you predict it would be? A chalkboard full of stoichiometry problems? Wading through the atomic masses on the periodic table? Bubbling beakers? Something else? In any case, I’m guessing his or her first answer would not be, “Creative writing.”

10 Percent Happier

 If this is a site all about chemistry teaching, what in the world does a book called "10% Happier" have to do with anything? Let me explain....I'll try the short, condensed, one page executive summary.

Do you have a favorite acid-base titration lab?

HCl and NaOH, a strong acid - strong base titration? Citric acid and NaOH, a weak, triprotic acid - strong base titration? Do your students standardize the NaOH solution as a first step?

Moles, Formative Assessment and Moving Forward....

Formative assessment can be a double edged sword. It can be and often is extremely helpful. Some quick short three or four well worded questions at the beginning of a unit provides information about student abilities. A teacher can skip teaching information that kids already know or the teacher can discover concepts that he or she assumed students know but do not. Formative assessment about "Moles" can provide data that is hard to deal with. Can the students handle scientific notation? How well are students at basic math skills?
