Addressing this question is essential if scientists are committed
to teaching based on evidence rather than tradition (4). The
answer could also be part of a solution to the “pipeline problem”
that some countries are experiencing in STEM education: For
example, the observation that less than 40% of US students who
enter university with an interest in STEM, and just 20% of
STEM-interested underrepresented minority students, finish with
a STEMdegree (5).
