This is the index for Chemistry Q&A videos developed by Dr. Glenn V. Lo, faculty colleagues (Ms. April Dupre, Dr. Vincent Giannamore, Ms. Cynthia Lamberty, and Dr. Jeremy Wessel) and students at Nicholls State University (Department of Physical Sciences). The development of most of these videos is funded through Project VALUE (Video Assessment Library for Undergraduate Education) by the Louisiana Board of Regents SELECT Grants Program (Contract No. LA-DL-SELECT-13-07/08). Other videos were developed by students for honors credit in Chemistry courses at Nicholls.
