Abstract

Nomograms are an ancient and efficient mathematical tool for solving complex problems. It is a graphical representation of a mathematical function that allows solving equations without requiring extensive manual calculations. Although electronic calculators have relegated their use, nomograms still have advantages in engineering education, especially in repetitive calculations and the two-dimensional representation of multiple input and response variables. In addition, nomograms help handle different unit systems, reduce the probability of magnitude errors, and are robust to failures. These tools have been tested on undergraduate and graduate students in various engineering fields. Subsequently, a Likert scale survey was conducted, which shows that students have a great interest in these tools and find them helpful in the engineering learning process. Even though 78.4 % of the respondents had not used nomograms, 86.5 % believe this analogical tool allows a reasonable interpretation of the phenomenon when there are many variables. Furthermore, there is a majority opinion that teachers should use nomograms in teaching.
