The educator who put forward the whiteboard theory is Locke, an outstanding British philosopher and thinker. In psychology, it refers to the theory of children's psychological primitive state. He put it forward while studying the origin of cognition. The word "whiteboard" is a free translation of Latin, which means a white wax board that has not been carved with a knife and pencil, because Aristotle, the ancient Greek and Roman, first used it as a metaphor for making a note board with a wax board. Later, it refers to the mind that is not influenced or stimulated by external things.

After criticizing the concept of talent, Locke developed the idea of whiteboard and demonstrated the basic principle that knowledge comes from experience. The main content of the whiteboard is Locke's view that at the beginning, the human mind is like a clean whiteboard. With the increase of experience, ideas and marks will appear on the whiteboard, which explains the argument that knowledge comes from experience.

Locke was born into a lawyer's family in England and studied at Christian College of Oxford University. Dissatisfied with the boring classroom education in school, Locke began to study experimental philosophy and medicine, and then he became an academician of the Royal Society with his own achievements. Locke had a great influence on the development of liberalism in philosophy and was praised as the founder of modern liberalism by later generations.

On philosophical issues, in addition to his whiteboard view, he also advocates that the world is made of matter, and the essence of human senses can be mainly divided into "primary" and "secondary". The so-called main properties refer to properties that are inseparable from the material itself, such as shape, quantity, state of motion, etc. The second sex refers to the nature that exists only in human perception, such as the color and smell of substances.
