Another dot in the blogosphere?

You had one job

Posted on: November 18, 2018

One might take a simple observation (like the one tweeted below) and turn it into a teaching moment.

At first glance, you might see nothing wrong with the set up and leave it at that.

As the Twitter personality points out human foibles like laziness or oversight, you might look for something wrong. So a second look might reveal how the rolled up screen cannot be lowered past the projector.

Even so, anyone who has used a short-throw projector knows that 1) it is typically used with a wall-mounted whiteboard (like the one in the same photo), and 2) the projection on the board is often interactive. The second point means that the presenter can tap or write on the board — this requires a stationary surface, not a dangling one.

Still, someone whose job was to install the projector could have also removed the old screen. But even that is not nuanced enough. Why replace one type of projector with another?

Administrators and policymakers have bought into the sales pitches of vendors who say that such interactive projections are the next big thing. They are not. They leave the teacher squarely at the front of the classroom, with little involvement of the learners.

To teach is the learn twice.

If the adage that “To teach is to learn twice” is true, then we understand why teachers become content experts. They are constantly unpacking and repacking content for others.

How about the learners? Would they not benefit from teaching one another more often than not?

If teachers have just one critical job (for the record, they have many), it is to ensure that students learn effectively and meaningfully. Presentations on screen do not ensure learning; performance using the new knowledge, skills, and/or attitudes do.

Learning is not a spectator sport. --Chickering and Ehrmann
