Tejeda, Santa; Dominguez, Angeles – International Electronic Journal of Mathematics Education, 2019
Understanding a graph in pairs, in a productive way, improves the comprehension of a concept. In this research, we had 2 objectives: 1) to delve deep into the behavior of 15 pairs of remedial physics students when solving a problem with a graph of velocity, 2) to understand the interchange of personal meanings during their interactions. We posed…

Zavala, Genaro; Tejeda, Santa; Barniol, Pablo; Beichner, Robert J. – Physical Review Physics Education Research, 2017
In this article, we present several modifications to the Test of Understanding Graphs in Kinematics. The most significant changes are (i) the addition and removal of items to achieve parallelism in the objectives (dimensions) of the test, thus allowing comparisons of students' performance that were not possible with the original version, and (ii)…
