bc thinks the second referred article is of great interest to LK.
p.s. One of the advantages of AAPT membership.
only about half of the students were able to deduce that the
amplitude of the wave will also increase with time, producing
qualitatively accurate models like the one shown in Fig. 4(a). The
most common misconception was that the amplitude of the wave would
remain constant with time, as illustrated in Fig. 4(b). Through
manipulating the computational model, students with the misconception
recognized that the amplitude of the wave does in fact increase
with time. However, even after this stage, many could not explain the
physical cause for this amplitude increase. Only through a final full
class discussion, in which students with more accurate models
explained in their own words why the amplitude increases during the
inspiral phase, did the remainder of the students understand this
aspect of the system. More specifically, the students explained to
their peers that the curvature of spacetime becomes more extreme as
the massive objects move closer together (as seen in the fabric
demonstration).
without losing focus on topics already in the curriculum.
