programming to schools.
1925-1935 Peak activity for radio use.
The radio did not have a great impact on schools.
In the beginning, poor audio reception and the cost of
equipment were obstacles to use.
The lack of fit between the broadcasts and teachers’
instructional agendas led to the abandon of radios in the
classrooms when television became available.
6. Television
TV was the focus of attention during the 1950s and ‘60s.
Television channels for educational purposes appeared.
Disadvantages:
Schools found it difficult the purchase
and maintenance of equipment.
It proved nearly impossible to broadcast instruction
when individual teachers needed it.
By the 1970s much of the enthusiasm for instructional
television had been exhausted.
7. The Era of Computers
The next technology to capture the interest of educators was the
computer.
1950s & 1960s computers had little impact on schools because it was
difficult and expensive to house the huge machines in schools.
19760s & 1970s CAI- Computer-assisted programs developed by
Gordon Pask.
The computer could keep track of student’s work and provide a record of
each student’s progress for the teacher. Teachers were skeptical of the
new medium.
1980s- the appearance of microcomputers made educators enthusiastic
about computers.
CALL: Computer-based materials for language teaching were developed.
40% of elementary schools and 75% of secondary schools in the US had
computers.
The ratio of computers to students was five to one.
8. The Era of Computers
1981- IBM was the first to develop a PC.
- The first educational drill and practice programs
were developed for personal computers.
1983- The Apple II computer found widespread
acceptance in education because PCs better fitted the
teacher model of instruction.
