Green boards once again

In the days when I was a uniform wearing student, the boards were green and teachers wrote with white and coloured chalk. After serving my NS, I entered university and the tutors were using white boards and water-based markers.

Apparently the school teachers have also switched to white boards since that time. Now, the school teachers are switching back to green boards. But they will be using some solvent to write, not something as low-tech as chalk. I suppose it will be easier for the students who are rostered to clean the classroom.

The words on the board also seem to be written by chalk, but it is actually a liquid solvent.

The green board is an innovation from Korea; two schools in Singapore have been trying it out since the beginning of the year.

Each set up costs S$350.

Gerald Koh, Green Board Importer, said, “(It is) green because it is scientifically proven that green is the best contrast for the human eye…like night vision goggles are in green.”
