ChemEd X Talk: Assessment Tools to Examine Students’ Reasoning with Multiple Representations of Bonding

Learning chemistry requires students to become fluent in the symbolic language of chemistry. Developing expertise requires that students move beyond manipulating equations and symbols to create explanations with particulate models of matter to explain their observations in the laboratory. Failure to accurately interpret and connect these multiple representations of matter and Johnstone’s Domains – macroscopic, particulate, and symbolic - is one source of students’ misconceptions. We hope you will join us on September 29th at 8pm EST to learn more about this topic from Stacey Lowery Bretz.

Fun with Formula Stoichiometry: “Who poisoned Veronica Merriweather?”

"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry for students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.
