Real vs Ideal - Do Students "Get It"?

Allowing students to confront the failure of a model and then helping them construct a new or slightly modified model to account for new observations is at the heart of the process of science. Ben Meacham shares one approach that can be deployed with a variation of depth, making it attainable for anyone learning about chemistry.

Lesson to determine the relationships between acid strength, Ka, pH, Molarity, and percent ionization

After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.

What informs the grade a student earns in your class? w/ Erica Posthuma

Grades should provide feedback to students, parents, and teachers as to the progress students are making toward learning targets. Meaningful grades require good assessment practices. Erica Posthuma presented a ChemEd X Talk on May 11th, 2021, providing an overview of effective assessment design. She discussed writing and communicating learning goals, developing targeted questions and prompts, and scoring using a standards-based approach. You can watch the edited recording of Erica's Talk here.
