Ionic Bonding Curriculum Unit: An Electrostatic Framework, Mary Frank Lamar

Theses and Dissertations--Education Sciences

This mixed methods study compared two groups of high school students’ understanding of the ionic bond and the dissolving process. A 5 lesson curriculum unit was developed using Taber’s electrostatic framework (1997) focusing on the electrostatic forces between ions compared to a molecular framework (business-as-usual) and the Next Generation Science Standards (NGSS Lead States, 2013). The lessons were developed to integrate spatially integrated experiences. Experimental (new curriculum unit) and business-as-usual (criss-cross method) students had their spatial skills tested before and after learning about the ionic bond using the Purdue Spatial Visualization-Rotations Test (PVST-Rot; Bodner & Guay, 1997). Students’ content was …
