The September 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: copper chemistry; safety; using brewing to teach chemistry; 3D-printed models; learning using games; open-ended approaches to teaching; innovative methods to teach biochemistry; polymer chemistry; organic synthesis labs; teaching physical chemistry; chemistry field trips.
In a previous post I talked about an equation balancing lab that I have been doing with my students involving building molecular models. This time I would like to focus on another lab that I have developed for my model kits.
Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.
The genesis of this paper started with a request from a former student, Thomas Kuntzleman, now a professor of chemistry. He asked if I would consider submitting my thoughts about ‘big ideas’ in chemistry. In his email he attached a paper that I had written for the Journal of Chemical Education six years earlier1. That article was submitted the year after I retired and was a response to a submission questioning the utility of the Principle of Le Châtelier.
Just this week I'm reviewing equilibrium with my IB Chemistry seniors after they finished some summer study on the topic. One of our classes was spent manipulating a classic equilibrium involving copper ions and a copper-chloride complex ion.
The August 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: blue bottle reaction revisited; precollege professional development; chemical education research on intermolecular interactions and bonding; integrated courses; activities involving kinetics, enzymes, and gases; nanomaterial & polymer laboratories; organic synthesis; NMR teaching resources; book recommendations for summer reading.
Who inspires you? Do you have a “chem teaching rockstar” whose work fires you up as you enter another school year? Is there an author whose work you consistently turn to for his or her insights into the chemistry classroom? Or maybe memories of a past teacher of yours?
I am a very firm believer that the world of physical science can be visualized and is an excellent medium for teaching students to model and to picture what happens at the molecular level. The first topic we decided to explore was balancing chemical equations. This seems like such a simple topic to chemistry teachers but I have found that it can be quite challenging for many of my inner city students. The first thing they ask me for is a list of rules that they can follow. We can discuss the problems of algorithmic teaching in a later post! For the time being let’s talk about how to get students to understand why they need to balance equations and discuss what we can call “Conservation of Atoms”.
The July 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: cost-effective instrumentation, including 3D printed instruments and low-cost spectroscopy; laboratory instrumentation and equipment; effective teaching assistants in chemistry; laboratory experiments; resources for teaching; puzzles and games to introduce the periodic table.
Back to school time means back to lab time too. Students new to chemistry have a lot on their plates the first few labs—learning unfamiliar safety procedures, becoming accustomed to writing lab reports, even figuring out which glassware they’re looking for in their lab space. How can teachers help them to navigate this newness? Two articles in the July 2016 issue of the Journal of Chemical Education are useful resources for “back to lab” time.
