In many fields of science and investigation, blackboards have been replaced with whiteboards or slide show presentations. 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.Sep 24, 2019
Mathematics professor Brian Conrad, the director of undergraduate studies for the Mathematics Department, said that nearly 100% of math faculty members at Stanford teach using chalk and chalkboards. This partiality for chalk, according to fourth-year Mathematics Ph.Oct 17, 2021
Chalk talks are especially good if the speaker did not rehearse it (verbally) or (worse) reads from notes. The reason is that it provides insight into the thinking of the mathematician. This can be lost in slides or written down papers.
Mathematics provides an effective way of building mental discipline and encourages logical reasoning and mental rigor. In addition, mathematical knowledge plays a crucial role in understanding the contents of other school subjects such as science, social studies, and even music and art.
If you're still wondering whether are chalkboards still used in schools or not, your answer is yes, they are. While interactive whiteboards and regular whiteboards continue to take over many new classrooms, it's also easy to see why so many educators are reluctant to give up their chalkboards.
“Many physicists like to do a back-of-the-envelope calculation before delving deeper into a computation, and blackboards are a great tool for that”, says Tibra Ali, another theorist at the Perimeter Institute. Indeed, there's a trophy-like quality to a clever piece of work prominently displayed on a blackboard.Jun 1, 2017
Blackboards are preferable over whiteboards for drawings or designs as blackboards are better in colouring and shading. However, chalk dust can cause breathing problems and allergies, but you won't encounter this problem in using whiteboards. You can decide which one to use based on your needs.Mar 31, 2020
A chalk is softer than slate so it can be used for writing while granite is harder than slate, so it can cut or mark (scratch) the board . So, a chalk can be used and but not a granite to write on the board.

One likely reason: U.S. high schools teach math differently than other countries. Classes here often focus on formulas and procedures rather than teaching students to think creatively about solving complex problems involving all sorts of mathematics, experts said.Feb 28, 2020
First, there are two meta-problems: 1) The lack of consensus around the goals of K-12 math education. Many people have strong opinions, but they are often at odds with one another. 2) The lack of consensus around the proper way to define and measure the success of the math education system.Feb 25, 2014
Why do we learn math that we will never use? Math is not entirely useless. It teaches you basics that can help you later in life. So when you learn “useless math”, you are actually learning basic skills of problem solving that you will most definitely need at least once in your life time.Dec 18, 2021
