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.

Session 2, a 3 hour session, extends the formative assessment experiences in session 1a and offers participants an opportunity to engage in an innovative lab formative assessment activity. Teachers will continue to build a collaborative professional learning community with a connecting activity, thinking like a student, and a chemical thinking discussion. The session requires a lab classroom for teachers to experience the Pringle design challenge. Time will be spent exploring the Formative Assessment Enactment model more deeply. Session 2  focuses on Chemical Control and touches on three of the six overarching ACCT objectives.

Conceptual dilemmas will occur as teachers confront the philosophical, psychological, and epistemological assumptions that differ between a traditional conceptualization of chemistry learning and chemical thinking. Teachers are asked to organize instruction around the Chemical Thinking Framework instead of a topic based approach.

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.
