I started teaching in a chronological order when I began using Modeling Instruction in my classroom. During the second year of "walking in the footprints of the scientists that came before us", I wanted my students to see where they were walking and a colleague and I came up with the idea of making footprints for each of those scientists and posting them on a timeline.
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.
Using Isotopes Matter and the class discussion: 55-60 minutes
This exercise is intended as an ice-breaker for a first or second class meeting. It also serves as an introduction to physical & chemical properties and application of the macro/micro/symbolic representations of chemical phenomena. Finally, it also provides a framework to mention many of the topics to be covered in a general chem first semester course.
This summer I had the opportunity to attend my first Biennial Conference on Chemical Education (BCCE) in Greeley, Colorado. When I first expressed interest in this conference more than one fellow high school educator told me some version of, “Don’t bother with that. It’s a bunch of stuff for college professors, it won’t be of use to you.” Nothing could have been further from the truth. Yes, much of the programming is directed at a higher-education audience, but many of the workshops and symposia have something to offer for precollege educators and there is a very vibrant and continually growing strand of high-school specific programing.
I display and live a class motto in order to give a framework to the scientific intent of my community of learners. My particular motto is a quote from Freeman Dyson: "Science is an objective struggle between the precision of tools and the ambiguities of nature."
BCCE 2016 was an amazing couple of days. It is kind of like drinking from a fire hose. Here were some high points that you might find helpful. As one participant was heard saying, "It is kind of like rocket fuel for the school year."
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.
During our review since last week, resonance was labeled as one of the most tricky concepts (along with electron pushing in my opinion), despite lots of practice and instruction. My teaching sequence consists of defining and providing examples of conjugation (after learning about hybridization), delocalized electrons, and finally pushing electrons if conjugation exists. I remember from teaching at the college level that resonance was also a tricky topic for many undergraduates.
Thinking Like a Chemist
The May 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: assessment & learning theories, science literacy & chemical information, engaging young chemists in chemistry, analysis of real-world samples, organic chemistry in the classroom and lab, computational chemistry in the laboratory, thermodynamics, kinetics projects, understanding hydrophobic & hydrophilic materials.
With the end of the school year approaching, educators are not only developing their semester exams, they are preparing for the upcoming school year as well. Although each individual educator has their own approach to improving their curriculum, many will be spending their time off aligning their curriculum to the Next Generation Science Standards. Currently eighteen states have adopted the Next Generation Science Standards, with additional states developing their own modified version. The idea of revising curriculum for each and every course can be daunting as educators try to identify a common theme that can be applied throughout the entire department. So where do we start? How do we thread a common theme for the professional development provided in our subject area?
