WHAT IS TECHNOLOGY? «Technology is the coordinated application

of knowledge and skills,

in order to find solutions

that satisfy our needs and

solve our problems.»

Its principal elements are: · materials and their properties

· knowledge and concepts

· technical drawing

· IT and the Internet

· working techniques and

· economic factors Technologies - 3º ESO - 2014/15

INVENTIONS ACTIVITY

Put the following inventions

in chronological order: telephone, telegraph, television, radio.

!

Use the Internet to find out who invented them and in what year.

Need analysis

The first stage consists of studying the need to be satisfied and looking at

similar cases and their results.

Technologies - 3ยบ ESO - 2014/15

Individual analysis and solution for the problem

Each person must think of

a solution to the problem which they then present to the other members

of the group team.

Making a

group decision

Each solution is presented to the group and

one of them is selected.

Construction

We construct the object by following the assembly process that we’ve previously planned.

!

Throughout the process we may have problems which we didn’t anticipate; we can record these problems on an incident sheet.

Technologies - 3º ESO - 2014/15

Verification and

evaluation

We must evaluate carefully the final result of each project. We can carry out self-evaluations of our own projects, or crossevaluations between

the different groups.

!

Finally, we must evaluate the impact of our project on the economy, society and the environment.

MANAGEMENT AND ORGANIZATION

OF THE WORKSHOP In technology we use many types of tools: Physical tools: tools to measure, to draw, to mark, to cut, to saw, to drill, to nail, to screw, to join and to fasten.

• Tool and materials for drawing.

• IT tools: word processors, spreadsheets, presentation programs, database programs and computer graphics programs and tools.

•

ORGANISATION OF THE WORKSHOP Workspace

Work groups

!

We keep tools, materials and projects here.

It’s a place where students work on different tasks.

Documentation

!

Students work in groups.

Each student has a specific role and must assume a responsibility.

The roles of the members of the work group must rotate, so that each student can work in all the areas.

Tool panel

!

There is an area of the workshop where we keep useful documents related to projects.

BUSINESS ACTIVITIES Companies that produce

goods carry out similar procedures to those

we follow in the classroom.

Technologies - 3ยบ ESO - 2014/15

The principal activities of companies are management, production, distribution and logistics.

BUSINESS ACTIVITIES Companies use advertising campaigns to sell their products.

Campaigns for some products can be so aggressive that consumers often buy products that they don’t need, or will pay inflated prices for them.

Technologies - 3Âş ESO - 2014/15

By contrast, there is a constant demand and usually a stable price for normal or necessary goods like bread and other basic foods.

IMPACT ON THE ENVIRONMENT Industrial activities derived from technological advances have caused some serious environment problems .

Some technological advances have led to exhausting of some natural resources, and social inequalities between countries and regions.
