Perhaps they suffer from over production of acid. I think an over-the-counter antacid would be a better idea. Taking it for no good reason is not a good idea.

They are very hungry teachers??

I guess you are thinking of people who do this who have not got access to a pharmacy. If so, it may be a way to get calcium if their diet, for some reason, lack this. Otherwise, I suspect Don is right.

Is it because they can't tell the difference between   " Chalk & Cheese " ?

Quote
Pica is a medical disorder characterized by an appetite for substances largely non-nutritive (e.g., clay, coal, soil, feces, chalk, paper, soap, mucus, ash, gum etc.) or an abnormal appetite for some things that may be considered foods, such as food ingredients (e.g., flour, raw potato, starch, ice cubes, salt, blood). In order for these actions to be considered pica, they must persist for more than one month at an age where eating such objects is considered developmentally inappropriate. The condition's name comes from the Latin word for magpie, a bird which is reputed to eat almost anything[1]. Pica is seen in all ages, particularly in pregnant women and small children, especially among children who are developmentally disabled, where it is the most common eating disorder.
