Adjusting Classroom to improve projector and whiteboard use for learning

At YISS we have data projectors in each classroom, but no Interactive WhiteBoards.

An idea to make our classrooms more amenable to data-projector use; to gain one of the benefits of a SmartBoard:  
Currently most classrooms have 2 large WhiteBoards attached to, and centered on, one wall of the classroom.  They also have an electric-rolldown projection screen centered on that wall, with a projector aimed at the screen.  Thus, when the screen is not rolled down, the image projects onto the WhiteBoards, with the metal border of each board precisely down the center of the image!  
The projector lens is focused on the roll-down screen; but the additional distance to the WhiteBoard is not so great as to make the image fuzzy when projected directly onto the Board.  However, the vertical metal frame down the middle makes the image almost useless when projected directly onto the Boards.

Solution, given existing purchasing stock of WhiteBoards:  shift the Boards at the front of the classroom so that the projector image is completely on a WhiteBoard.  If we require symmetry and centeredness, we can install 3 WhiteBoards across the wall.  Or, simply move the extant 2 Boards to one side. 
This solution will allow me to use the data-projector for quick writing exercises or multiple-choice formative quizzes, or even a quick presentation without having the noise and time of rolling the screen up and down.

The WhiteBoard surface is acceptable to display large text and images;  more precise displays and videos will need the official roll-down screen.

Review: Jerusalem, Jerusalem: How the Ancient City Ignited Our Modern World

Jerusalem, Jerusalem: How the Ancient City Ignited Our Modern World by James Carroll My rating: 4 of 5 stars Fascinating comprehensive worldview, with Jesuitical logic in a broad sweep that links religion in a circular way to violence and the solution to violence. The author shows a great command of history and religion, with extensive endnotes to support or expand upon most of his claims; however, some sweeping indictments will certainly be resisted by the more fundamentalist People Of The Book (that is, the Abrahamic religions). A core symbolic thread is Abraham's near-sacrifice of Isaac on Mt.Moriah, the supposed site later called Jerusalem -- the author deftly cites that scene throughout the many centuries since the original event, demonstrating the human tendency to misinterpret that near-sacrifice in order to rationalize our own tendency to violence and scapegoating. I started the book in audio form, but found it unlistenable -- the author's c...

Kite Runner is with us again

 Six or so years ago, I taught The Kite Runner to three successive sets of tenth-graders, and marveled at the effect the novel had on me and on these adolescents.  That age is a marvelous time for a humanities teacher, as we see callous children grow out of their self-centered cocoons and flex their world-empathic feelers.  They grow into the world outside them and realize they truly have agency -- or will have agency and responsibility for human actions.  Amir, the main protagonist of Kite Runner is so identifiable with those adolescents learning to take responsibility for their callous actions.   And of course we think of Kite Runner now that Afghanistan once again plunges into Taliban rule -- we particularly worry about the fate of the Hazara (news stories already cite random executions of Hazara men).   We can only wring hands and pray that the Taliban will have to adapt and tolerate more than they did before -- but I am not optimistic. ...

This Is How They Tell Me the World Ends: The Cyberweapons Arms Race by Nicole Perlroth My rating: 5 of 5 stars And the hits just keep on coming! This excellent book details an unrelenting onslaught of cyberattacks, and outlines the author's own gradual realization of the dangers of internet warfare. It is a lengthy but worthwhile read -- actually, I lost the book for a while because I did not want to read it at bedtime, for fear of nightmares or disrupted sleep! Indeed the book is changing my stance toward online security -- multi-factor authentication, definitely! As with most of us, the author first downplayed the fear tactics promoted by sellers of security packages; but after years of research she has come to wonder that more disaster has not happened yet. She briefly but baldly calls out the recent presidentical administration for wreaking havoc on US defense, by eliminating a cybersecurity department, incensing the Iranian and Chinese gover...
