if you want to know more about the history of computer check this out and see the wonder of advantage and this advantages of computer in the history and in the present When we study the many aspects of computing and computers, it is important to know about the history of computers. Charles Babbage designed an Analytical Engine which was a general computer It helps us understand the growth and progress of technology through the times. It is also an important topic for competitive and banking exams.History of Computers Generation
The word ‘computer’ has a very interesting origin. It was first used in the 16th century for a person who used to compute, i.e. do calculations. The word was used in the same sense as a noun until the 20th century. Women were hired as human computers to carry out all forms of calculations and computations.
By the last part of the 19th century, the word was also used to describe machines that did calculations. The modern-day use of the word is generally to describe programmable digital devices that run on electricity. 1st Generation: This was from the period of 1940 to 1955. This was when machine language was developed for the use of computers. They used vacuum tubes for the circuitry. For the purpose of memory, they used magnetic drums. These machines were complicated, large, and expensive. They were mostly reliant on batch operating systems and punch cards. As output and input devices, magnetic tape and paper tape were implemented. For example, ENIAC, UNIVAC-1, EDVAC, and so on.
2nd Generation: The years 1957-1963 were referred to as the “second generation of computers” at the time. In second-generation computers, COBOL and FORTRAN are employed as assembly languages and programming languages. Here they advanced from vacuum tubes to transistors. This made the computers smaller, faster and more energy-efficient. And they advanced from binary to assembly languages. For instance, IBM 1620, IBM 7094, CDC 1604, CDC 3600, and so forth.
3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit. A single integrated circuit (IC) is made up of many transistors, which increases the power of a computer while simultaneously lowering its cost. These computers were quicker, smaller, more reliable, and less expensive than their predecessors. High-level programming languages such as FORTRON-II to IV, COBOL, and PASCAL PL/1 were utilized. For example, the IBM-360 series, the Honeywell-6000 series, and the IBM-370/168.
4th Generation: The invention of the microprocessors brought along the fourth generation of computers. The years 1971-1980 were dominated by fourth generation computers.

Origin and development of ict
The development of ICT can be described in four phases:
1) The audio-visual phase emerged before 1920 through the use of paintings, charts, educational films and other tools.
2) The cybernetic phase from 1920-1950 saw the emergence of feedback concepts to direct and control classrooms.
3) The psychological and sociological phase of the 1940s-1960s focused on learning theories from those disciplines.
4) After 1980, the computer and telecommunication phase established ICT as the blending of hardware and software technologies to make teaching and learning more effective.
On line learning

History of teacher education. pptx
The document traces the history of teacher education in India from ancient to British periods. In ancient India, meritorious senior students called "pattacharyas" would assist teachers and take charge of teaching when teachers were absent. During the British period, educational boards first recognized the need for teacher training and established some initial training centers in the 1800s. Over subsequent decades, the British gradually expanded the teacher training system across India, establishing more training schools and colleges and improving standards of teacher education. By the early 1900s, there was a growing network of training institutions across India with thousands of students receiving instruction in teaching methods and practical experience.

Promoting inclusive classroom adopting udl
This document discusses promoting inclusive classrooms through adopting Universal Design for Learning (UDL). UDL is an educational framework that provides flexibility in how information is presented, how students respond or demonstrate their knowledge and skills, and how students are engaged. The three principles of UDL are providing multiple means of representation, multiple means of action and expression, and multiple means of engagement. UDL aims to reduce barriers in instruction by accommodating individual student differences and maintaining high expectations for all. When adopted in the classroom, UDL provides students with choices for how they learn and demonstrate their learning through flexible lesson content, methods, and assessments.
