FACTORS IN THE TECNOLOGICAL PROCESS
When a
solution
has been found, it is converted into a
technique
. This is a skill
- something we we know how to do and that is used for future technological
solutions. This is the base of
technological evolution
.
Scientific knowledge and its application are needed to obtain an efficient
technological solution. The process involves a combination of procedures and
resources to obtain a result.

Make a list of the knowledge you require and the techniques you will
use while making the drip irrigation system.
Have you ever resolved a problem?
How? Using your knowledge and
skills, and following a plan? This is
what technology is.

What is involved in making a mobile phone? Look at the photo and
discuss these questions.
a)
What is it for? How does it work?
b)
How big is it? Why is it this size?
c)
What materials is it made of?
d)
How much is it? Is this a good price for a mobile phone?
The factors in the technological process:
1. Knowlege of physical and scientific concepts
is important. The more
scientific knowledge we have, the easier it will be to obtain an optimal solution
to the problem.
2. Technical drawing
is used to transmit the idea of an object.
3. Knowledge of materials and their properties
is essential for choosing the
right material for the project.
4.
Development of
work techniques
are important for better results (speed,
reliability, cost and safety).
5. Economic factors
are decisive in the progress of technology. They influence
the way we make objects and decisions about design and use of materials.
6. Information technology (IT)
facilitates the management of informaton, the
speed in which it is transmitted and the automisation of processes.
All these factors are studied in the technological process. Although these factors
do not appear to be related, we shall see by the end of the unit that together they
serve to design and construct objects that satisfy our needs.
❚
The factors involved in the
technological process are:
knowlege of physical and
scientific concepts; technical
drawings; materials and
their properties; working
techniques; economic factors
and information technology.
