Like most chemistry teachers, one of the first things I go over in the beginning of the year is unit conversions. Students come into my class with all sorts of prior knowledge concerning unit conversions; some good, some bad and some downright ugly.
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.
Exploration of Instrument Design and Performance
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.
One of my favorite things to talk about with my colleagues is the use of lecture demonstrations in teaching. There seems to be a push in my district to stop using chemicals whenever possible and get to computer simulations and video in place of wet chemistry. I don’t think they are thrilled with me since I can’t envision ever taking the chemistry out of chemistry.
During the first week of school, I welcome my students to the What Not To Do Lab. The PDF is available for free at the Laboratory Safety Institute website. I use the cartoon activity to review their Safety Contract handout from the night before (I use the one from FLINN Scientific). With more than 30 safety violations shown, the cartoon serves as a great ice breaker as I have each student introduce themselves and then list a safety infraction being shown on the cartoon.
This can be completed easily within a 50 min class period.
n teaching we regularly change our class structures and routines and we implement new “interventions” in hopes of changing classroom dynamics or reaching more students. I know that most of the time I make these decisions based upon anecdotal evidence, perhaps after glancing at a handful of exit tickets from my students or based upon how I “felt” the class went. Recently, though, I’m finding myself a little more hesitant when making a claim about my class. I require that my students support their claims with evidence, so why wouldn’t I also support mine with evidence?
A New Year with a New Volume of Resources The January 2015 issue marks the start of the 92nd volume of the Journal of Chemical Education and is now available online at http://pubs.acs.org/toc/jceda8/92/1. This issue features colorful chemistry; using stories and writing to learn; demystifying chemistry literature; cost-effective activities and materials; experimenting with chromatography and natural products.
Last Thursday (11/6/14) I attended a workshop on NGSS through our local RESA (essentially an ISD for the county/region). I’d like to touch on some of the things I took away from this workshop and will post again after the next follow-up workshops in December and March.
Passion for and Dedication to Chemistry and Education The July 2014 issue of the Journal of Chemical Education is now available online to subscribers at http://pubs.acs.org/toc/jceda8/91/7. The July issue features a tribute to J. J. Lagowski, green chemistry principles, book recommendations for the summer, organic chemistry in action, computation chemistry experiments, resources for teaching fluorescence spectroscopy.
Robert H. Hill, Jr., Ph.D., Chair, ACS Committee on Chemical Safety asked us to post the following alert about the Rainbow Demonstration. I hope chemistry teachers will share the alert with their networks.
