Evaluations are part of everyday life. This multi-part blog series aims to expand upon the evaluation process. Part 2 focuses on what evaluation is and how it differs from research.
This demonstration offers an alternative to the disappearing rainbow demonstration using readily accessible materials.
Have you seen the rainbow candy experiment? It's a very simple experiment that involves pouring water into a plate that has M&M's candies or Skittles arranged in a pattern. Very curious shapes of sharply divided regions form spontaneously. How does this happen?!
Some of the challenges associated with virtual instruction include connecting with students and checking for understanding in real time. On February 2nd, Michael Farabaugh presented a ChemEd X Talk about how he uses the interactive features of Nearpod to create formative assessment items that provide valuable feedback and facilitate student participation. You can watch the edited recording of Michael's Talk and access the lesson he shared during the presentation here.

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.
ChemEd X Talks with Chad Husting about how he has transitioned to standards based grading during a pandemic! He will share a quick trick that has the potential to solve many of the problems that teachers struggle with including having a mix of face to face and virtual students and keeping up with late work, make-up work and missing assignments! Join the conversation! Register for this 30 minute Zoom meeting to be held Feb 9 at 7pm EST.
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.
