Abstract

QUNLAB is a program to help students in Quantitative Analysis with their laboratory calculations. Its use ensures that students learn the proper way to do the calculation by themselves. Immediate feedback results in a very positive learning experience. The program uses the student's data to correctly calculate a result, which it compares with the student's result, previously calculated from the same data. If the results are not the same, the student knows a calculation error has been made. Grading is uncompromised because the program does not know the actual analysis of the student's unknown. Since the student's reported result is not in error because of mistakes in the calculation, the final grade is a reflection of the quality of the student's experimental work.
