Why do so many teachers stand in front of what they want pupils to look at?

During my first week of teaching back in 1980 in a fairly challenging school in Tower Hamlets I was faced with writing or drawing on a blackboard (one of the roller types) anything I wanted the whole class to see. I was very conscious of my own school days in the 60s and 70s when I struggled to concentrate on what was on the board as the teachers continually stood in front of it, however expert and light footed they were in dancing from side to side.

At the end of that first week I found some technology which would address the problem - an Over Head Projector (OHP). This fundamentally changed the way I was able to interact with the class. I was able to keep facing the class the whole time, maintaining eye contact. I wasn't obscuring the screen by dancing around back and forth all the time. I could ensure that all pupils had uninterrupted sight lines at all times. I used an acetate roll which provided virtually limitless writing space, and what's more when I had to teach the same topic again to a different class I was able to use the same material instead of having to write or draw the same things all over again.

So has modern digital technology improved things still further? In my view, the interactive whiteboard has moved things backwards - literally. Teachers who were using OHPs successfully within a secure pedagogy now are expected to once more start turning their backs on the class, pirouetting from side to side, and using nimble contortions to avoid obscuring too much for too many for too long. Official reports and other publications from the likes of Becta are littered with photographs of teachers proudly displaying the output from a computer on their faces and their clothes. Actually, sometimes it is possible to make out some of the text if they are clean shaven but hardly the best viewing surface for maximum visibility.

Becta health and safety guidelines (issued on behalf of the Government) make it very clear that anyone at the front of the class should never look directly out into the room, in the direction of the projector beam. Even if not looking directly at the light from the bulb there are concerns about the effect on people's peripheral vision. So not only does this particular form of technology take us back to the days of my first week in teaching in terms of interrupting lines of site to the content, but is even worse in that teachers shouldn't turn to look at the class before moving well away from the screen.

So back to my question which forms the title for this post. Why do teachers stand in front of what they want pupils to look at? Before interactive whiteboards I'd always assumed it was because they couldn't afford OHPs. But that can't be right, can it? Interactive whiteboards are much more expensive than OHPs. There must be another reason. Maybe they think that it doesn't matter to have uninterrupted sight lines. Perhaps they should ask the pupils. Would they like family members to continually perform the same antics in front of the TV screen while trying to watch EastEnders. I think not.

I'm not getting at teachers here - they are the victims as much as the pupils. But how would I have reacted to being given an Interactive Whiteboard because some local authority adviser had persuaded the headteacher that 'every class should have one'? Well, I would have used it as a very expensive projection screen. I would have loved all the interactive software that came with it, but of course that runs on the computer, not the Whiteboard. I would have still done all the interesting interactive things using the software, but with a cheap graphics tablet, keyboard or mouse. And where would I be in the classroom when doing this? Well, somewhere which meant that everyone could see what I was doing on the screen.

I am reminded of the Cadbury's Smash advert whenever I pick up a Becta booklet and see another picture of teacher's face decorated with a web site! Those of you of a similar generation will know what I mean.

You have a point. Teachers will have to figure out some way to work around the "occlusion" problem. This might mean creating lessons that involve students at the board, and/or using a connected tablet PC to control the board from a distance so they can have more face-to-face contact with the students.

Yes, Lynn you are right. Some teachers in Barking and Dagenham use a wireless tablet and pen to control and interact with the display from anywhere in the class. The tablet is also passed around the class saving the disruption of pupils having to come to the front to help move the lesson forward. The pace tends to be greater.
