Senioritis. Seniors come down with it. Underclassmen claim it's contagious. Teachers do not appear to be exempt. Let's face it: Summer is coming and we all know it. We all want it. We are all ready for it! However, the calendar declares it is not here yet. What do you do when your students are unmotivated?
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
A raspberry pi is the one of the world's cheapest computers. It is a $35 computer that runs off of an eight gig SD card. Anyone can program it with Python (a relatively simple coding lanquage) and it can do small things.
In this blog post I'll describe a recent attempt at using BCA Tables for teaching stoichiometry. I discuss the method I used with one introductory chemistry class to teach both the algorithm method and BCA tables to learn more about a technique I've been curious about for a while.
Although not a chemistry app, I have been using Classkick(link is external) in my chemistry class strictly as a formative assessment tool and wanted to share the many benefits I have found with it. Classkick is a free app that is currently available through the itunes(link is external)store. I use it with the iPads I have in my classroom. Soon, classkick will be available on other devices besides just the iPad.
Previously I wrote about taking part in a district-wide high school blended learning pilot. You can read about it here. I received my Chromebook cart near the end of February/beginning of March. A little late but just in time for the periodicity unit I was planning as a blended unit. The following is a breakdown of how I designed the unit.
In the lab, students are given a 1.5 gram samples of copper. The copper is taken through a series of five chemical reactions ending with the precipitation of solid copper. After the five reactions, students are asked to return their 1.5 gram samples of copper to the teacher.
It is really hard to get to know THAT kid especially when I have classes of other kids who are important and have needs also. Stack on top of this teenage hormones, spring, nice weather, prom, AP tests, state testing and trying to sell as hard as I can how fun "stoichiometry" is....I now run the risk of turning a bunch of other kids into THAT kid pretty quickly.
One of the resources we have vetted is an interactive slideshow from PBS on both ionic and covalent bonds. Teachers using Modeling Instruction will find these resources elucidate a model of electron behavior which adds to the particle story of matter we have been telling throughout the year.
Chemists Celebrate Earth Day
The April 2016 issue of the Journal of Chemical Education is now available online to subscribers. In honor of Earth Day 2016, the April issue includes a variety of content that provides ideas and suggestions for bringing environmental chemistry to students on the topics of: water quality; climate science and greenhouse gases; atmospheric chemistry; sustainability, green chemistry, and environmental awareness; and energy storage technology. Also in the issue are articles on: outreach and public understanding; teaching organic chemistry; physical chemistry; exploring biochemistry with proteins; research experiences in the laboratory; educational resources.
In a dramatic movie trailer voice: “The Boiling Point. Gone without a trace. Or were they? The scene… a mystery. Had they disappeared? Been broken up into unrecognizable pieces? Can our hero find the answer? Or will it be too late?”
