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...

Review: A Swim in a Pond in the Rain: In Which Four Russians Give a Master Class on Writing, Reading, and Life

A Swim in a Pond in the Rain: In Which Four Russians Give a Master Class on Writing, Reading, and Life by George Saunders My rating: 4 of 5 stars Must-read for any teacher of writing, and certainly for any would-be writer; also for any aficionado of Russian literature. This book is a distillation of the author's creative-writing class; reading it feels much like attending his class -- all that's missing is the back-and-forth of a seminar. View all my reviews

Review: The Empathy Diaries: A Memoir

The Empathy Diaries: A Memoir by Sherry Turkle My rating: 5 of 5 stars I cannot stop talking about this book, and not just because the author is a favorite of mine, with her earlier books about the effect of technology on education and our psyches. She describes encounters with so many other famous writers and technologists -- she was Present at the Creation of our computer-saturated internet world. Note that the title is purposely plural: several personal points are interwoven into the chapters, sometimes repeating details that a "normal" book would elide. But she is a talented writer and psychologist: the very writing style is intended to affect the reader and illustrate psychological points. I did cringe at the repeated references to the Freudian incident with her stepfather (fear not, dear reader -- no outright abuse here, just psychological trauma unearthed by years of analysis, along with all-too-typical infidelity and familial...
