Chalkboards versus Interactive Whiteboards

While the rest of the world are replacing blackboards with whiteboards, a 2017 dissertation notes that teachers in Japan are still using chalkboards. Back in 2015, it is estimated that three out of four classrooms in Japan are still delivering content to students via chalkboards. Apparently, there is something "calming" with the green color of a chalkboard. Indeed, if the only difference between a chalkboard and a whiteboard is aesthetics or a more practical reason, avoidance of chalk dust, one should not really expect a significant difference in learning outcomes between these two media.
There remains, however, the cost ($5000 per classroom). And the secretary of education of the United Kingdom has recently stated that "Replacing blackboards with interactive whiteboards was a waste of money."

For any novelty that comes with significant costs, it is important that we examine what it exclusively brings. We should not be spending $5000 per classroom just to change the background color from green to white. Interactive whiteboards are so much more than a spot for our scribbles.
