Answer (1 of 18): I feel that I have to say a few words in defence of blackboards (chalkboards). The following observation belongs to the great mathematician Israel Gelfand. Using chalk on a blackboard, we write by moving the entire arm. With felt …

In these diagrams, mysteries are being born and solved. For the last year, Jessica Wynne, a photographer and professor at the Fashion Institute of Technology in New York, has been photographing mathematicians’ blackboards, finding art in the swirling gangs of symbols sketched in the heat of imagination, argument and speculation.
But chalk is cheaper and biodegradable. It smells better than whiteboard markers and is easier to clean up, mathematicians say. It is also more fun to write with.
It gets all over your hands and your clothes," said fifth-grade teacher Stephanie Tatel of the Amistad Academy, a newly renovated charter school in New Haven. Architect Jay Brotman, whose firm renovated an office building to create the academy, said teachers recommended replacing the blackboards with "white boards.".
The buyers say marker boards cost about the same as blackboards - generally between $150 and $200 - so it's more a question of teacher preference than price. Brite Inc., a company in Quincy, Mass., distributes both kinds of boards.
Different assignments can be given in contrasting colors, and overhead projectors can display transparencies on the white boards. "The markers are easier to see than yellow chalk on black, especially from the back rows," Tatel said.
A blackboard is a hard and smooth board with a dark surface on which you can write and draw using chalk, while whiteboard is a board with a smooth, white surface on which you can write and draw using dry-erasable pens.
A blackboard is a hard and smooth board with a dark surface used especially in a classroom for writing. Writings or drawings are made on the board with the use of chalk, sticks of calcium carbonate. This board is pained black so that it reflects the white chalk. There are also green coloured boards, which work like blackboards.
What is Whiteboard? Whiteboard is a wipeable board with a white surface used for teaching or presentations. Melanin, steel, porcelain, hard-coat laminate, and tempered glass are materials commonly used for making the surface of the whiteboard. Erasable markers are used to write on them.
We call these whiteboard markers or dry erasable markers. They can be erased with a dry eraser or a cloth. However, if you keep the writing for many days, you may find it difficult to erase. Whiteboards became popularly in the mid-1990s, and they have mostly replaced blackboards in many classrooms and offices.
Therefore, it’s important to take into the difference between blackboards and whiteboards before you decide which one to buy. Blackboards are preferable over whiteboards for drawings or designs as blackboards are better in colouring and shading.
