Query: New Directions in International Masterclasses   International Masterclasses (IMC) have developed since their introduction in
2005. Masterclasses for International Day of Women and Girls in Science (IDWGS)
and World Wide Data Day (W2D2) are innovations that began two years ago and are
going well. With IDWGS masterclasses, a new pathway has been opened for high
school girls to be encouraged in physics. W2D2 establishes new ways to bring
masterclass activities directly to high school classrooms. New masterclass
measurements beyond those for the LHC have been developed and tested, notably
the MINERvA neutrino masterclass, which is the first IMC offering in neutrino
physics and the first based on a Fermilab experiment. In the MINERvA
measurement, students are able to study interactions of a neutrino beam with
carbon nuclei, using conservation of momentum to draw conclusions. Other
masterclass measurements related to Belle II and medical imaging are also in
the testing stage. More neutrino masterclasses are in development as well,
especially for MicroBooNE. A longer-term goal is the creation of a DUNE
masterclass measurement as that facility reaches the data-taking stage.
