Modifying the test of understanding graphs in kinematics [PDF]

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 ...
