Resumen
In this article we present several modifications of the mechanical waves conceptual survey, the most
important test to date that has been designed to evaluate university students’ understanding of four
main topics in mechanical waves: propagation, superposition, reflection, and standing waves. The most
significant changes are (i) modification of several test questions that had some problems in their original
design, (ii) standardization of the number of options for each question to five, (iii) conversion of the two-tier
questions to multiple-choice questions, and (iv) modification of some questions to make them independent
of others. To obtain a final version of the test, we administered both the original and modified versions
several times to students at a large private university in Mexico. These students were completing a course
that covers the topics tested by the survey. The final modified version of the test was administered to
234 students. In this study we present the modifications for each question, and discuss the reasons behind
them. We also analyze the results obtained by the final modified version and offer a comparison between
the original and modified versions. In the Supplemental Material we present the final modified version
of the test. It can be used by teachers and researchers to assess students’ understanding of, and learning
about, mechanical waves.
