Unit # 1

INTRODUCTION TO TECHNOLOGY

Chapter Notes

Ch.1 Objectives

• After completing this chapter students should be able to:– Define Technology– Tell/Explain the difference between science and

technology– describe technology as a dynamic area of knowledge– relate specific technology to a specific era of time

Technology

What is it?

• It is....– the technical means humans use to extend their potential– the technical means humans use to improve surroundings– the knowledge of using tools and machines to do tasks– humans using knowledge, materials, tools, and systems

to make their lives easier and/or better.

Technology Defined

• Technology is used to meet human needs and wants.

• Technology is the use of tools, materials, and systems to extend human potential for controlling and modifying their environment.

• -HUMAN INOVATION IN ACTION

Why study about Technology?

If we study it, we can ...• improve humans ability to do work. (Improve productivity)

• improve the quality of items that are produced/manufactured

• create new and develop better ways to meet the needs of humans

• deal better with new technologies and the exploding growth of technology

• calm fears associated with the changes created by technology.

Science vs. Technology

Are they the same?

Which comes first?

Science & Technology

• Science Education = Study of the natural laws of the universe. Scientist do research.

• Technology Education = Study of the man-made world. Technologist develop things.

• Humanities Education = Study of the relationships between groups of people. How science, technology, and people effect people.

Science & Technology (Cont’d)

• Science and technology are connected and dependent upon each other, but different.

• Science deals with understanding our world and why things happen the way they do.

• Technology deals with doing things in our world.• Humanities deal with human actions within the natural and

human made worlds.• Leave out any of these three type of knowledge and false

judgments and operational mistakes will be made.

Technology: Ever Evolving!

• Technology is not new to the human world.– Humans create technology & always have.

• Primitive vs. Civilized Societies– Primitive = does not try to control or improve

their natural condition.– Civilized = attempts to control or improve their

natural condition.

Technology: Ever Evolving (Cont’d)

• Civilized Society’s History is divided into major divisions (Ages or Eras) related to the “tools of the time”

1. Stone Age – manipulated abundantly found items to create tools.

2. Bronze Age – used processes to change metals into desired objects.

3. Iron Age – used processes to build and create machines to do work.

4. Industrial Age – “Industrial Revolution” – Mass production & Industry

5. Information Age – using technology to enhance both materials and processes

6. What’s Next ???????????????????

Technology

• Technology has always been a part of human existence!• It changes human lives and changes as life progresses!• It makes life better for many people, but not always!• It can create serious damage to people, society, and the

environment!• Technological people can properly develop, select, and

responsibly use technology.

• This is the challenge to “YOU” !!!

Unit # 1

INTRODUCTION TO TECHNOLOGY

Chapter 2 Notes

Ch. 2 Objectives

• After completing this chapter students should be able to:– Discuss technology as a response to human needs

– Discuss technology as a human-made system

– Discuss the parts of a technological system

– List and describe the inputs of technological systems

– Describe the two major types of processes used by technology

– Describe feedback as it is used in technological systems

Technology Systems

What makes one?• Technology Systems .....

– work together to perform in a predictable way– share common characteristics

1. Arise out a human need2. They are designed and developed by people3. They integrate resources to produce outputs4. They have consequences to people, society, and environment5. They are evaluated by people6. In time they are modified or abandoned

– are totally human entities!!

Technology System Components

The components of a technological system are:1. Inputs: elements that flow into the system and are consumed

2. Processes: action part of the system. Two Major Types.

3. Outputs: desired and some undesired results of the system

4. Feedback: regulates or makes adjustments to the system

5. Goals: Reason for having the system. Two Major Goals!

Technological System INPUTS

Inputs into a technological system are:1. People: most important input; involved in every aspect of a system

2. Materials: all natural matter that is directly or indirectly used in the system

3. Tools: the technical means of manipulating parts of the system

4. Energy: the ability to do work. Powers the processes

5. Information: (knowledge & data) “I know and I understand!”

6. Finances: Money needed to purchase resources required by the system

7. Time: all activities in a system use time; fixed amount/day

Technological System Processes

All technological systems are characterized by action; steps to be taken. The steps to complete system tasks are called processes.

• There are two main types of processes – Problem-Solving Processes & Transformational Processes.

– Problem-Solving Processes involve procedures necessary to develop the technological system.• These are the creative actions.• Process uses the problem-solving model.

– Transformational Processes involve changing inputs into outputs• Two major categories – Production Processes & Management Process.

Transformational Processes

• Production Processes – Actions taken to change raw materials into products. They include:

– Analyzing – planning & design– Obtaining – material receiving– Producing – plant action taken on materials– Delivering – getting the product out (shipping)– Operating – people using & maintaining machines & tools

• Management Processes – Actions to ensure quality in production.– Planning – establishment of plans– Organizing – establishment of operational procedures – Actuating – providing emphasis to start operations– Controlling – directing and managing personnel

Technological System OUTPUTS

The entire reason for having a system. The desired output will meet a human need or want!

• Outputs = Desired, Undesired, & Unexpected results– Desired Results – The reason the system is created!

– Undesired Results – Waste, Scrap, Pollution, Social Unrest

– Unexpected Results – Not anticipated or expected & may be good or bad.

Technological System Feedback

• The adjustment, control, or evaluation tool of a system.

• This part maintains a functional and useful system that creates useful quality products.

• Without feedback a system has poor odds of making a useful or desired product.

Technological System Feedback (Cont’d)

• Feedback monitors a system!

• Feedback controls a system!

• Feedback evaluates a system!

Technological System GOALS

• There are two main general goals for every technological system.– Must meet a human need or want !!– Must create an opportunity to benefit the

individual or company that creates it !!

Technology SystemCh. 2 Summary

• Technology Systems are developed:– to create new technology– to control a technology– to enhance a technology– to work in a predictable way & achieve desired

results.– for humans by humans to meet needs & wants

Technology SystemCh. 2 Summary

(Cont’d)

• There are five parts to a Technology System 1. Inputs: elements flowing into the system

2. Processes: Actions taken to change inputs into outputs.

3. Outputs: Results of the system

4. Feedback: Regulates, maintains quality

5. Goals: General reason for having a system

Technology SystemCh. 2 Summary

(Cont’d)

• Inputs: Resources needed by the system (7)– People– Materials– Tools– Energy– Knowledge– Money– Time

Technology SystemCh. 2 Summary

(Cont’d)

• Processes: Actions taken on resources– Two Main Types of Processes

• Problem-Solving Processes

• Transformational Processes– Production Processes

– Management Processes

Technology SystemCh. 2 Summary
