History of Education TechnologyAssigment #1Lecturer: Paula LedesmaStudent: Ezequiel BlancoUTN 2013
When did the computing historybegin?• It began approximately in 3000 BC. Peoplefrom Mesopotamia invented the abacus,which is still used nowadays to count andmake quick calculations.
When did the computing historybegin?• During the second half of the 17th century,the French mathematician, inventor, writerand physician Blaise Pascal invented the firstmechanical calculator. In order to solve mathsequations, the “Pascaline” used cogs andgears.
The computing history and education• Centuries later,between 1943 and 1956in the US, the firstvacuum tube-basedcomputers weredeveloped; universitieshelped in computerdevelopment effort;technology used in wareffort.• They used punch cardsto input and externallystored data. It requireda compilar and it wasup to 4 K of memory.
The computing history and educationThe first electronical digitalcomputer• It was also used during theWWII, so as to makeballistic firing tables for theUS Department.• The Electronical NumericalIntegrator and Calculator1956 IBM 350 RAMAC• It was developed by BellLabs. It used transistors; itcontained programmingcomputer languages, suchas FORTRAN and COBOL. Itwas up to 32 K of memory.
Technology continues developingSmaller computers• In the 1960s, these newcomputers used integratedcircuits. They were smaller,cheaper and their processorspeed were increased. Theywere up to 3 million bytesof memory.Microcomputers• Microcomputers weredeveloped between the late1960s and 1970. They wereprocessor chips. Altar andApple sold the first minicomputers which had biggerstorage space and memory,as well as faster processingspeeds.
Education TechnologyComputers at schools (1963)• Money is invested onschools; computers arebought. However, themainframe andminicomputers in use at thistime are using batchprocessing methods that donot fit well with the singleteacher-as-manager-of-learning methods in use inmost schools.Computers at universities (1965)• High-level programminglanguages such as Fortranare being taught atuniversities. Schoolvocational trainingprograms begin to includecomputer maintenance.
Education TechnologyFrom 1970 to 1990• Computers started to beused for personal uses; theywere known as PC. Theywere rather expensive atthe beginning, but later on,their prices begandecreasing. They couldstand alone or beconnected to othercomputers as a networksystem.The revolution of the Internet• In the late 1980s, the Britishcomputer scientist TimBernes-Lee developed theHTML and the World WideWeb (www) was born later.
Computers, the Internet and educationSchool and universities• Little by little, more andmore computers were usedat schools and universitiesfor teaching purposes.Then, when the Internetwas born, teachers had toadapt to this new way oftransmission of information.The number of Internet users keepsincreasing and increasing01020304050607080 North andLatinAmericaEuropeAsia andOceaniaAfrica
New challenges for teachers• According to M.D. Roblyer, educationtechnology is the combination of theprocesses and tools involved in addressingeducational needs and problems with anemphasis on applying the most current tools:computers and their related technology.• What are the implications for teaching?
