WebNaCl-type structure. (a) Use ionic radii to predict the length of the cubic unit cell edge. (b) Use this value to estimate the density. (c) At high pressure the structure transforms to one with a CsCl-type structure. (c) Use ionic radii to predict the length of the cubic unit cell edge for the high-pressure form of RbI. WebLearning (CSCL). CSCL r efers to collaborative learning that is mediated in some way by computer technology (Stahl, K oschmann, & Suthers, 2014). It rests on three major pillars: the technologies that suppor t and enable CSCL, the pedagogical designs that apply CSCL t o learning, and the modes in which learners collaborate.
