Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.
The May 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: electrochemistry and corrosion; textbooks; research on the chemistry teacher pipeline, argument-driven inquiry, and online homework; using everyday objects to teach; teaching organic chemistry with games; communication and writing; examining and creating innovative curriculum; computer-aided discovery activities; exploring kinetics; interdisciplinary laboratory investigations; from the archives: applications of 3D printing for teaching chemistry.
The recently published iPad app ChemTube3D (and related website for classrooms without iPads) will be discussed. It has a great deal of functionality - including a large selection of organic mechanism animations and models of structure and bonding.
Augmented reality is a type of technology that uses an app to turn a hidden QR code into a three dimensional object on a screen as viewed by your camera. Elements 4D attempts to bring augmented reality to chemistry.
Looking over my student's papers, there may have been more misconceptions created because of the way I planned the curriculum. In all of the experiments students can see and observe that not all of the crystals or material dissolves yet the water starts to conduct. In their minds there is evidence that they believe either something DOES dissolve or it does NOT. Clearly, partial dissolving is initially too much to consider.
Last month, I shared about a new PD opportunity I had the privilege of participating in called Gizmos. You can read about it here. After Thanksgiving break, my Chemistry 1 and Honors Chemistry 1 classes began our Chemical Reactions unit.
Atomsmith works really well on Chromebooks and other platforms. Students can manipulate molecules, add water, do experiments, heat solutions and examine intermolecular forces all on the particulate level. Another nice feature is the "Experiment" section. There are a number of guided activities, usually never more than a page or two. I have found them to be great supplements for activities, experiments and demonstrations.
The purpose of a lab practicum is to assess a student’s understanding of the content by completing a hands-on challenge. These assessments focus more on problem-solving skills than technique.
Throughout the last ten years teaching both chemistry and Advanced Placement Chemistry I have realized that the concept of equilibrium does not receive enough attention in my first-year chemistry course. Sure, the concept of equilibrium is a topic mentioned and identified throughout the course however the dialogue in regards to conditions that would shift the chemical system is minimal at best.
Organic chemistry was when I fell in love with chemistry. Also known as Chem 210 at the University of Michigan, it was the first time I actually started to connect what was going on at the nanoscopic level to the macroscopic world. Since then, I’ve been hooked.
