Ionic Blocks Richard S. Sevcik, Rex Gamble, Elizabet Martinez, Linda D. Schultz, and Susan V. Alexander
"Ionic Blocks" is a teaching tool designed to help middle school students visualize the concepts of ions, ionic compounds, and stoichiometry. It can also assist high school students in reviewing their subject mastery.

What Happens When Chemical Compounds Are Added to Water? An Introduction to the Model–Observe–Reflect–Explain (MORE) Thinking Frame Adam C. Mattox, Barbara A. Reisner, and Dawn Rickey
This article describes a laboratory designed to help students understand how different compounds behave when dissolved in water, and introduces the modelobservereflectexplain (MORE) thinking frame, an instructional tool that encourages students to connect macroscopic observations with their understanding of the behavior of particles at the molecular level.

Electronegativity and the Bond Triangle Terry L. Meek and Leah D. Garner
The dependence of bond type on two parameters, electronegativity difference (??) and average electronegativity (?av), is examined. It is demonstrated that ionic character is governed by the partial charges of the bonded atoms, and metallic character by the HOMOLUMO band gap.

Teaching Chemistry with Electron Density Models Gwendolyn P. Shusterman and Alan J. Shusterman
This article describes a powerful new method for teaching students about electronic structure and its relevance to chemical phenomena. This method, developed and used for several years in general chemistry and organic chemistry courses, relies on computer-generated three-dimensional models of electron density distributions.
