Chapter 1 is a seismic study of the mantle structure of the passive margin of northeastern North America. This region experienced multiple episodes of rifting and orogenesis in the past, and the study aims to understand how the Wilson Cycle impacts the geometry of the upper mantle seismic structure beneath southern New England using Sp receiver…

A three-step active-learning approach is described to enhance the spatial abilities of general chemistry students with respect to three-dimensional molecular drawing and visualization. These activities are used in a medium-sized lecture hall with approximately 150 students in the first semester of the general chemistry course. The first activity…

This study employed a case-study approach to reveal how an ability to think with mental models contributes to differences in students' understanding of molecular geometry and polarity. We were interested in characterizing features and levels of sophistication regarding first-year university chemistry learners' mental modeling behaviors while the…
