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.
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.
EdPuzzle is a content delivery tool that can increase student engagement and metacognition. Here, we will explore how to use this application to help your students learn in a remote or hybrid setting.
The December 2020 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: teaching during COVID-19; examining models used by students; chemical structure; game-based learning; interdisciplinary courses; teaching chemistry using plants; laboratory instruction with real-world context; fluorescence; exploring spectroscopy; thermodynamics; chemical education research; from the archives: photography.
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.
In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.
In this activity, students learn about the mole. In section 1, students learn what a mole looks like for different substances. In section 2, students learn how the number of protons and neutrons in the nucleus determines the molar mass of an element by comparing individual isotopes in a PhET simulation..
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
Many teachers have students draw models and diagrams to help them illustrate how matter behaves. Teachers can uncover and address possible misconceptions quickly using this strategy. The author describes how to create interactive particle diagram activities that are easy for students to use online. This strategy is applicable to almost any particle diagram and should be useful for teachers during virtual lessons.
