A kind of stabilized mixed/hybrid scheme
for Reissner-Mindlin plates is proposed  with conforming
isoparametric bilinear interpolations of deflection/rotations. The
choice of shear stress modes is discussed. It is shown by
numerical experiments  that
 fulfilling an energy orthogonal condition for stress approximations is
crucial to avoiding "shear locking".
