I have two DDs and am in a STEM field. I agree with geofizz and master_of_none. I have two DDs and my older one in particular prefers to discuss things, etc. My younger DD and I probably do fine with show and do, but prefer the other way as well. My girls are lucky since it seems (thinking about it now) many of their subjects including science and math are taught using group dynamics.

FWIW, the ratios in my work group are similar to what is described above.

I sent the link on to my DDs Middle school math teacher and she hopes to get it posted on the MS website as an opportunity.
