P588: Electronic prelabs, postlabs and data collection in organic chemistry laboratories - Student usage and application

Christoper Callam, Noel Paul, Richard Spinney (Ohio State University, USA)

We have developed and implemented electronic prelabs, postlab and data collection exercises for organic chemistry laboratory experiments, and these computerized scoring methods have emerged as an increasingly powerful tool in our teaching laboratories.  Over the course of the last two years, thousands of students have had to input stoichiometric calculations, draw chemical reactions, report research data, submit unknown identifications and provide answers to experimentally pertinent questions.   Their work has been immediately scored prior to their laboratory experiment, which allows for better preparation and understanding for a successful laboratory experience.  The shift of grading effort from human to computer allows instructors and teaching assistants to devote more of their time and energy to enriching the educational experience of their students.  The implementation of these grading methods has resulting in reduced grading burden in a time of decreased resources, and contributed to improved stoichiometric and structural understanding of organic chemistry amongst our laboratory students.
