The history of computer development could be divided into several stages: - ** Mechanical computer era (1623 - 1945)**: The early calculation tools were human hands and simple chips, followed by methods such as "knotting ropes to record". The German scientist Chekkard created the first mechanical computer in human history, which could perform six-digit addition, multiplication, and division operations. After that,"punched paper tape," binaries, Boole algebra, hand-operated computers, and push-button computers appeared, laying the theoretical foundation for digital computers. - ** Modern computer development stage that began in 1946 **: February 14, 1946, at the University of Pennsylvania, the world's first electronic digital computer, ENIAC, was invented. It had parallel computing capabilities through reprogramming between different parts, but its functions were limited and its speed was slow. Its appearance marked the birth of modern computers. Later, the invention of the crystalline device, which was used in computers in 1956, and the magnetic core memory led to the creation of the second generation of computers, which were small in size, fast in speed, low in power consumption and more stable in performance. The development direction of computers was to become larger, smaller, more information, and more intelligent. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.

Who is singing the lesson plan and reflection of the small class?

There were many singing content in the reference materials about the lesson plans and reflections of the small class, such as "Happy Song,""Pulling Radish,""Little Frog Looking for Home," etc., but there was no clear mention of who was singing these lesson plans. In these lesson plans, the teacher usually demonstrated singing first to guide the child to learn to sing. For example, in Happy Song, the teacher first guided the child to appreciate the song and then let the child sing along; in Pulling Radish, the teacher used the accompaniment recorded before class to help the child familiarize himself with the song; in Little Frog Looking for Home, the teacher first sang the song loudly and then the child sang along.
