Using a computer to run the General Chemistry Laboratory

Rudolph W. Kluiber, Rutgers University, Newark, NJ

Teaching General Chemistry Laboratory is a time consuming, labor intensive task. GenChem, a programmed computer, doing most of the work normally done by lab instructors remedies this. From pre-labs to final grade, GenChem takes over most routine teaching duties. Before coming to the lab, students must pass individualized pre-labs using GenChem. This is their ticket to start work in the lab. GenChem also allows students to download and view videos. These replace laboratory instructor talks. In the lab, GenChem individualizes student experiments to prevent mindless copying. It also gives a short no-credit quiz at the start of lab work to refocus the student on the experiment at hand. Students enter experimental data into GenChem and, on a one time basis, GenChem may comment if there are serious errors which can be easily corrected. Calculations and conclusions are also entered into the computer and again the student receives a one time error warning. Finally GenChem grades and records each student's work and produces the graded printout. GenChem keeps extensive and accurate records for the instructor. Except for grading of a few synthesized products and writeups, GenChem does all the grading. As an added bonus, Genchem allows students to do extra-credit experiments. These are short, simple but significant hands-on laboratory studies designed to make the student think. At the end of the semester, GenChem even produces the final course grade. GenChem can keep track of many different experiments in the same lab period so it facilitates makeups and repeats. GenChem helps students by providing timely feedback without discrimination. It demands increased accountability and keeps each student aware of their curent status. The instructor is relieved of tedious grading and record keeping, yet maintains control. GenChem allows them to do the fun part of teaching, interaction with the students.
