Chapter 1 Computer in Education
COMPUTER
COMPUTER GENERATION
FIFTH GENERATION
1980-present
Goal : to develop devices that respond to natural language input and output of learning and self organization.
Microchip and Multiprocessor
The beginning of artificial intelligence.
The fastest computer technology with the best memories storage compare to be the previous generation
FIRST GENERATION
Vacuum Tubes (1950s).
Storage and Memory : Magnetic Core.
Unreliable and hard to coordinate.
Large size, slow, expensive and undependable.
SECOND GENERATION
1956-1963
Heat generation problem that could damage to computer is still existing.
Transistor : The switches replacing vacuum tubes.
One transistor : equivalent to 40 vacuum tubes.
Transistor allow computers to become smaller, faster, cheaper, more energy efficient and more reliable.
FOURTH GENERATION
Microprocessors were introduced
Output operation.
Mouse and hand held devices are introduced
The introduction of Compact and Laser Disc " End-user computing "
Better circuits
Improved the processing technology.
1971-1980
THIRD GENERATION
Became accessible to the mass since it is smaller and cheaper.
Computer's speed drastically increased as well as its efficiency.
The Beginning of the Personal Computer (PC) era.
Faster, smaller size and more reliable compare to the second generations computer.
1964-1971
Integrated circuit, transistor were miniaturized and place on silicon chips, called semiconductors.
TYPES OF COMPUTER
A Personal Digital Assistant (PDA) is a handled microcomputer that trades off power for small size and greater portability.
PDAs typically use a touch sensitive LCD screen for both output and input
PDAs communicate with desktop computers and with each other either by cable connection, infrared (IR) beam, or radio waves
Normally used to keep track of appointment calendars, to-do lists, address book and for taking notes
A microcomputer is a micro-processor based on computing devices designed with chip and it is CPU
PC are typically used at home, at school, or at a business. available as desktop and portable models (laptop or notebook)
Personal computer (PC) and provided lots of application
Playing music or game.
Database management.
Spreadsheet calculations.
Surfing the web.
Sending and receiving email.
Creating graphics.
Photo editing
Word processing.
HISTORY OF COMPUTER
Educational computing existed only at large universities and was largely restricted to reading and typing text.
It has been about 40 years since educators and computer scientist began using computers for instructional purposes.
In the 1960s - 1970s instructional computing took places on large mainframe computers or occasionally on medium-sized computers.
COMPUTER SYSTEM
Software
A program is a set of instructions that the computer follows to manipulate data
Hardware
The peripherals are any devices attached to the computer for purposes of input, output and storage of data.
The computer itself, and the peripherals connected to it.
An
electronic device
which is capable of
receiving information (data)
Electronic device
operating under the control of instructions stored in its own memory
.
Electronic device operating under the control of instructionss stored in its own memory
Accept data : raw facts, figure and symbols
The processing cycle of information.
Input > Process > Output > Storage > Communication
Processes data information : data that is organized, meaningful and usefu
Information Technology
The use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, stores, secure and exchange all forms of electronic data.
INTRODUCE COMPUTER
WHEN TO INTRODUCE COMPUTER
Children younger than 3 years learn through their body
eyes, ears, mouth, hands and legs.
although they may return over and over again to an activity, they are full of movement, changing focus frequently.
Not a good for the developmental skills these children are learning to master.
Computers simply do not match children learning style.
Educators must be positive role models for the students.
Do not recommend that children under 3 years old to use computers.
Teacher must provide opportunities for students to access the computer to develop high-quality and activities with hands on use of current technology.
DEVELOPMENTALLY APPROPRIATE COMPUTER ACTIVATION
Computers and preschoolers
They learn to delegate responsibility, interact with others, solve problems and cooperate to reach a goal.
Children could also work in small group using internet web sites selected by the teacher.
Providing children with minimal help teaches them they can operate computer successfully
Computers for Kindergarten and Early Primary
Ways to use computer with 3- and 4- years old are different from the way we use computers in kindergarten and the primary grades
Computers
enhance children's self concept
, and children demonstrate increasing levels of spoken
communication and cooperation.
Computer have an impact on children when
children have free access and control the learning experiences.
children and teachers learn together.
the computer provide concrete material.
teacher encourage peer tutoring
teacher use computers to teach powerful ideas.
Children share
leadership roles
more frequently and develop positive attitudes toward learning
