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.
The authors revisit "flattening the curve" demonstrations published during 2020 to see how they could represent the impact of vaccinations on the COVID 19 battlefront. These demonstrations do not demonstrate the mechanisms of vaccines themselves, but are rather analogies to their potential effect on a population. In these analogies, gas production still represents illness, but this time people are represented by objects added to the solutions which either enable gas production (unvaccinated individuals) or do not enable gas production (vaccinated individuals). These simple experiments are best used as stand-alone demonstrations, and links to videos are included in this writeup.
Students were asked to watch a short video that describes the ways scientific information is communicated, how those pathways usually function and how they were altered by the pandemic. Students were then asked to discuss a series of questions about experts, peer review, and the issue of releasing research results prior to peer review because of the urgent need for useful information related to the pandemic.
On January 26, 2021, Melissa Hemling presented a ChemEd X Talk about “whiteboarding” in a hybrid or virtual classroom. Students collaborate in small groups on classkick.com to digitally analyze data, create and modify models, and/or complete practice problems. Melissa shares how she uses the digital whiteboards to gauge student understanding and pinpoint misconceptions like she did pre-COVID. You can watch the edited recording of Melissa's Talk and access the document she shared during the presentation here.
This creative activity will help engage your students in chemistry nomenclature.
Providing students with meaningful feedback greatly enhances their learning and achievement. With the move to online and hybrid formats, teachers have had to scramble to modify their usual process for communicating that feedback. On January 21, 2021, Ariel Serkin presented in a ChemEd X Talk about the process she is using and how she is providing feedback to her students remotely. You can watch the edited recording of Ariel's Talk and access the document she shared during the presentation here.
Interested in embedding interactive lecture and/or lab videos? PlayPosit provides a medium to do so. This post gives directions on how to get started.
The ability to provide meaningful feedback has been one of the most difficult aspects of hybrid and distance learning. Using the Chrome extension, Mote, allows teachers to attach an audio recording of their feedback to student work.
The January 2021 issue of the Journal of Chemical Education is now available online to subscribers. Modern chemistry programs must include the skills and techniques that enable their graduates to perform experiments safely, and, in response to a call for papers, scientists and educators from around the world have contributed articles to a special issue on Chemical Safety Education: Methods, Culture, and Green Chemistry. The articles in the issue are broadly distributed among topics covering resources, green chemistry, safety culture, and pedagogy. This issue is a resource for ideas and discussion to encourage "a new way to look at safety", with a focus on assessing hazards, minimizing risk, and valuing a strong chemical safety culture.
The ChemEd X team is pleased to announce ChemEd X Talks! These 30 minute live Zoom events are free, but registration is required. Teachers are asked to keep their video on, ask questions and participate in the discussion by offering their own ideas and experience with the topic. Register for our next ChemEd X Talk or find recordings for past Talks that you may have missed here!
