I am a first year graduate student, and I am trying to find a few good sources and ideas for my dissertation work.  I am interested in misconceptions in inorganic chemistry. As part of my project, I will be creating a new instrument that can be used in the classroom.  Right now, I am considering focusing on how students approach Lewis Dot structures for molecules beyond the octet rule or how to help students with 3D visualization of point group symmetry.  Does anyone know of any research or materials that might be helpful? Any comments or suggestions would be helpful!
