Loads of interesting ways to view instructional leadership here. Some good practical things to consider. These things are often cold, and so replete with nonsense verbiage that is meant to either play on buzzwords or build new ones that I find annoying to sift through. There is a healthy dose of that nonsense here.
A personal picadillo, and possibly a note more on the constant banging of the war drums of "progress in education" than the actual book here; The authors chose to lambaste the one-room schoolhouse and talk down about "traditional" modes of education, which feels a bit trite and quite rich considering the lagging literacy scores and generally poor performance of students in basic functions of collegiate and work development coming out of our public high schools which have been working on these new modes of education since the 90's. Maybe we should value the wisdom of the ancients, look at the fences they built, and try to see if possibly they had something right, instead of pushing constant progress irrespective of the enchantment of learning about our fascinating world, but I imagine that's just the thing, we can't have too many enchanted people, it would disrupt the progress of the few and the loud because it naturally breeds difference of experience. We of course need unanimity in the guise of independence, above all. They mostly skew toward just practical functions of supervision of teachers though and thus avoid allowing this particular noxious view to take center stage.
Just completed my EWU EDUC 551 Supervision of Instruction course and found this text very insightful and will be an administrative bible I refer to throughout my career. Here is crossing my fingers that I can lead a group of educators and truly make a positive impact on a community in Washington state.
