But to suggest that because these observational indicators (artificially) correlate with teachers» value - added scores at «weak» and «very weak» levels (see Notes 1 and 2 below), that this means that these observational systems might «add» more «value» to the summative sides of teacher evaluations (i.e., their predictive value) is premature, not to mention a bit absurd.

Directly related to the Review of Article # 4 prior (i.e., # 4 of 9 on observational systems» potentials here), these researchers found that Chicago teachers are, in general, positive about the evaluation system, primarily given the system's observational component (i.e., the Charlotte Danielson Framework for Teaching, used twice per year for tenured teachers and that counts for 75 % of teachers» evaluation scores), and not given the inclusion of student growth in this evaluation system (that counts for the other 25 %).
