Abstract	During the past several years a program has been developed at SUNY-Binghamton for the introductory Chemistry laboratory which allows the student to test his laboratory results in a particular experiment against those results expected for his sample. This test is performed during the regularly scheduled laboratory period, by the student, at a terminal located adjacent to the laboratory, and permits a rapid decision to be made by the student as to whether or not he should repeat the experiment in order to obtain worthwhile data. This operation is accomplished by way of the APL program CHEMLAB1, which performs the appropriate calculations on the student's raw date. At the time the repeat-no repeat decision is made, the student does not have, or get, the results of the detailed calculations made by the computer. Should a repeat be necessary, the student has enough time to perform a duplicate experiment on his relatively simple apparatus before the end of the lab period. Should no repeat be necessary, as is the case 60-70% of the time, the student can dismantle his apparatus and proceed with the calculations at his leisure, assured that the data is capable of providing a reasonable answer. After the student has understood the concepts of the experiment, and performed the appropriate calculations, he may enter his calculated data at the terminal, and receive a tabular output which tells his how well he did on the calculations and in the experiment. These interactions of the student and the program are shown in Figures 1 and 2. This output is turned in with the student lab report, and serves as a basis for student comments on the relative success or failure of his experimental work and calculations.
