 Developing Students' Spatial Skills in General Chemistry
 The study of chemistry requires the understanding and use of spatial
 relationships, which have been shown to be challenging for many students.
 This study implemented guided activities designed to strengthen students?
 spatial skills, with the aim of preparing  students for advanced study in
 chemistry and other future STEM coursework. A pre/post quasi-experimental
 design was employed in which the experimental (n = 209) and control group
 (n = 212) were administered a pre and post-test. The results of a one-way
 ANOVA  confirmed that student performance differed significantly between
 groups, indicating that the guided activities were successful in
 strengthening students? ability to reason with spatial information. In
 particular, the results indicate that students? improved their ability to
 identify symmetry planes, visualize in 3D, mentally rotate molecules, and
 translate between 2D representations and 3D molecular models. The results
 also suggest that a large amount of class time need not be devoted to
 enhance students skills, and that a diverse group of students can be
 trained together effectively without the need  to separate high and low
 ability individuals.
 STEM seminars are held at 4PM on the first and third Tuesdays of each
 month during the academic year in Hasbrouck 113. Everyone is welcome; no
 reservations are needed, and there is no charge. 
 Parking is available in the Campus Center Garage.
