What is the history of chalk?

First chalk (the natural one) was used in prehistory for cave drawings. The first chalk in sticks appeared when artists found them convenient. They made it by grinding the natural chalk (calcium carbonate), mixing it with water, clay and pigment (natural pigments were used like carbon for black or rust for red).

When was chalk first used in schools?

School houses across America rapidly adopted the chalkboard as it allowed them to educate larger numbers of children and saved teachers from the arduous task of re-writing problems on individual slates.

Where is chalk found?

Extensive deposits of chalk are found in many parts of the world. They often form in deep water where clastic sediments from streams and beach action do not dominate the sedimentation. They can also form in epeiric seas on continental crust and on the continental shelf during periods of high sea level.

Can we eat chalk?

They’re formed from the skeletal remains of minute planktonic green algae that lived floating in the upper levels of the ocean. When the algae died, their remains sank to the bottom of the ocean and combined with the remains of other creatures to form the chalk that shapes the cliffs today.

Who invented the chalkboard?

The chalkboard is widely believed to have been invented by a Scottish teacher James Pillans, in the nineteenth-century (About Blackboards, para. 7). Mr. Pillans “supposedly hung his students’ slates together on the wall, making a large ‘slate board’ to write up his geography lessons where the whole class could see them at once” (Wylie, 2012, pp. 259-260). The first documented case of the chalkboard however is found in America in 1801. Mr. George Baron is credited as being the first teacher to make use of a large black chalkboard to assist him with his instruction at West Point Military Academy (About Blackboards, para. 8). Regardless of where it was invented, either in the United Kingdom or in the United States of America, the fact remains that the chalkboard was created by teachers to assist with teaching, and is an important educational technology.

What is the chalkboard called?

A closer look at two teaching manuals published in the late nineteenth century demonstrate that the chalkboard, also called the blackboard , was the “main-stay and sheet anchor of a lesson” (Livesey, 1881, p. 6).

What was the Lancasterian method of education?

The increase in student population that resulted from the 1870 Education Act in Britain created the need to standardize education. Krause (2000) proposes that the British are responsible for the Lancasterian method that was arguably “one of the first ‘systematic’ approaches to education” (p.10). This newly standardized approach was advertised throughout the country via teaching manuals, which were published in mass and as Wylie (2012) contends “promote pedagogy as largely universal” (p.261). The chalkboard, having been deemed a necessity, was aggressively promoted in these teaching manuals that spread the word of this new standardized approach to education. Krause declares “chalkboards … were an essential part of the Lancasterian method because [they] kept costs low by minimizing the use of paper, ink, pens and books, and because [they] facilitated group instruction by monitors and teachers” (p.10). A closer look at two teaching manuals published in the late nineteenth century demonstrate that the chalkboard, also called the blackboard, was the “main-stay and sheet anchor of a lesson” (Livesey, 1881, p. 6). In How to Prepare Notes of Lessons: A Manual for Pupil Teachers and Students in Training Colleges, Taylor praises the chalkboard for its invaluable impact on teaching and learning. Taylor writes that:

What are teaching manuals?

Teaching manuals produced in the late nineteenth century in England outlined in precise detail how a lesson was to be taught. Wylie (2012) concurs that the “instructions portray the teacher as explainer, demonstrator and corrector. There is no active knowledge construction by students, only explanation followed by drill, with the teacher giving corrections” (p.261). The emphasis on rote memorization is demonstrated below in figure 1. In this lesson, Taylor (1881) demonstrates to the teacher the step-by-step process to teach the letters I, T, L and H. He leaves little to the imagination of the classroom teacher.

What is the most important technological innovation of all time?

A close look into the history of educational technology will reveal that an invention from over two hundred years ago remains arguably the most influential technological innovation of our time. It was Josiah F. Bumstead who first declared in his 1841 essay, The Blackboard in the Primary Schools, that the chalkboard is a groundbreaking technological invention (Krause, 2000). Numerous scholars have agreed with Bumstead’s pronouncement citing in reference to the chalkboard that “the inventor or introducer of the system deserves to be ranked among the best contributors to learning and science, if not among the greatest benefactors of mankind” (Krause, 2000, p.11; Ressler, 2004, p.71; Tyack & Cuban, 1995, p.121). With the advent of compulsory schooling in the United Kingdom in the late eighteen hundreds and the significant increase in student population in public schools, the British acknowledged a sudden need to adopt a unified education program. The chalkboard stood at the core of this new teaching culture. This report will argue that the chalkboard gave rise to the standardization of public education, and its integration into English classrooms in the nineteenth century led to the widespread advancement of rote memorization as the dominant teaching pedagogy in the United Kingdom.

Who invented the blackboard?

James Pillans, headmaster and geography teacher at the Old High School in Edinburgh, Scotland, is credited with inventing the first modern blackboard when he hung a large piece of slate on the classroom wall.

What are the advantages of blackboards?

As compared to whiteboards, blackboards still have a variety of advantages: 1 Chalk requires no special care; whiteboard markers must be capped or else they will dry out. 2 Chalk is an order of magnitude cheaper than whiteboard markers for a comparable amount of writing. 3 It is easier to draw lines of different weights and thicknesses with chalk than with whiteboard markers. 4 Dashed lines can be drawn very quickly using a technique involving the friction of the chalk (or chalk marker) and blackboard. 5 Chalk has a mild smell, whereas whiteboard markers often have a pungent odour. 6 Chalk writing often provides better contrast than whiteboard markers. 7 Chalk can be easily erased; writing which has been left on a whiteboard for a prolonged period may require a solvent to remove. 8 Chalk can be easily removed from most clothing; whiteboard markers often permanently stain fabric, wood (wood frame), etc. 9 Chalk is mostly biodegradable, whereas most plastic recyclers will not take whiteboard markers.

What are chalk sticks made of?

White chalk sticks are made mainly from calcium carbonate derived from mineral chalk rock or limestone, while colored or pastel chalks are made from calcium sulfate in its dihydrate form, CaSO 4 ·2H 2 O, derived from gypsum. Chalk sticks containing calcium carbonate typically contain 40–60% of CaCO 3 ( calcite ).

As a Paper Substitute. Due to the health risk posed by chalk dust, many chalkboards have been replaced with whiteboards in classrooms. Some of the earliest chalkboards were little more than small squares of slate, usually framed with wood to keep them from breaking.

How effective are slate boards?

Student slate boards were effective, but not particularly efficient, particularly in disciplines that required precise equations — science and math, for instance. Teachers would usually have to individually transcribe the problems onto each individual slate, which took up a lot of time.

Why did people replace blackboards with whiteboards?

In the 1990s, concern over allergies and other potential health risks posed by chalk dust prompted the replacement of many blackboards with whiteboards. A whiteboard is a plastic board, sometimes also known as a “dry erase board,” on which people use special pens to make colored marks.

Is slate too expensive to paint?

Despite the widespread availability of slate, it was still too expensive for some of the poorer and more rural school districts. Teachers in these circumstances sometimes resorted to painting a plaster wall or wooden panel with dark paint to imitate slate, and black-painted grit sometimes also worked. An old rag served as eraser. Students sometimes came up with these sorts of crude substitutes for their own individual supplies, too.

Is there a chalkboard in the classroom?

Chalkboards may still be found in some classrooms. The boom in slate usage is perhaps most profound when looking at the history of the chalkboard in the United States. Slate mining coincided with the development of the American railway system.

What is a blackboard?

What is chalk made of?

The chalk with which we write on boards isn’t actual chalk but gypsum, the dihydrate form of calcium sulfate. Gypsum is found naturally and can be used straight out of the ground in big chunks, but it can also be pulverized, colored, and then compressed into cylinders.

What is a blackboard in education?

Teachers now had a flexible and versatile visual aid, a device that was both textbook and blank page, as well as a laboratory, and most importantly, a point of focus. The blackboard illustrates and is illustrated. Students no longer simply listened to the teacher; they had reason to look up from their desks.

Where did the chalk come from?

Chalk from the White Cliffs of Dover, England. Chalk is so common in Cretaceous marine beds that the Cretaceous Period was named for these deposits. The name Cretaceous was derived from Latin creta, meaning chalk. The Chalk Group is a European stratigraphic unit deposited during the late Cretaceous Period.

What is the composition of chalk?

Calcite ( calcium carbonate) Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of sub-microscopic plankton which had fallen to the sea floor. Chalk is common throughout Western Europe, ...

How deep is chalk?

It was deposited on extensive continental shelves at depths between 100 and 600 metres (330 and 1,970 ft), during a time of nonseasonal (likely arid) climate that reduced the amount of erosion from nearby exposed rock. The lack of nearby erosion explains the high purity of chalk.

Where is the famous white cliff?

It forms the famous White Cliffs of Dover in Kent, England, as well as their counterparts of the Cap Blanc Nez on the other side of the Dover Strait. The Champagne region of France is mostly underlain by chalk deposits, which contain artificial caves used for wine storage.

Is chalk a porous material?

Chalk is highly porous, with typical values of porosity ranging from 35 to 47 per cent. While it is similar in appearance to both gypsum and diatomite, chalk is identifiable by its hardness, fossil content, and its reaction to acid (it produces effervescence on contact).

What is powdered chalk used for?

In field sports, such as tennis played on grass, powdered chalk was used to mark the boundary lines of the playing field or court. If a ball hits the line, a cloud of chalk or pigment dust will be visible. In recent years, powdered chalk has been replaced with titanium dioxide.
