AACT Webinar Series: A Visual and Intuitive Approach to Stoichiometry

This webinar will discuss how to approach teaching stoichiometry problems using a table set-up (commonly referred to as Before, Change, After tables) to make the process visually appealing and more intuitive for students. The process emphasizes proportional reasoning and explicitly connects the calculations to the particulate nature of matter.

Connections to equilibrium calculations will also be discussed to show how this method can easily be integrated in to your curriculum and benefit your students in more than one area.

Building Models of Isomers

Students will build models of isomers while the instructor walks around from station to station to critique the models. If the model is incorrect, the students rebuild until they get it right. The paper that accompanies this assignment is very easy to grade.

Misconceptions and Struggles with Double Displacement reactions and dissolving...

double displacement

Looking over my student's papers, there may have been more misconceptions created because of the way I planned the curriculum. In all of the experiments students can see and observe that not all of the crystals or material dissolves yet the water starts to conduct. In their minds there is evidence that they believe either something DOES dissolve or it does NOT. Clearly, partial dissolving is initially too much to consider.
