  1. Exploring Technology Standards: MSENGR-EET

  2. Are You Sure about That? • 1876: “This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us.” (Western Union) • 1895: “Heavier-than-air flying machines are impossible.” (Lord Kelvin) • 1948: “Television won’t last. It’s a flash in the pan.” (Mary Somerville) • 1977: “There is no reason for any individual to have a computer in their home.”

  3. Ask yourself • What does the statement mean? • Who said it, what was their role at the time? • Is it true? • How does this technology impact us today? (how has it changed?)

  4. Ask yourself: • Why do new technologies become accepted? • For example: television, telephones, computers.

  5. Preview Vocabulary • Technology • Science • Emerging technology • Impact • Quality • Technology assessment • Technological literacy • Invention • Innovation • Agricultural • Industrial • Information • Rate of change • Technology resources

  6. What is Technology? • The knowledge and processes used to solve problems by designing and making products and structures • The two parts to technology: • It solves a problem • It’s a product Technological Literacy – having an understanding of technology

  7. Invention & Innovation • Invention – a new device or system • Innovation – an improvement to an existing technology

  8. INPUT PROCESS OUTPUT FEEDBACK System • A group of parts that work together to achieve a goal

  9. Technology resources • People • Information • Materials • Tools & Machines • Time • Energy • Capital

  10. Technology changes lives • Farming led to waterwheel • Waterwheel led to not grinding grain by hand • Waterwheel also lead to many other changes • Social changes include: • One per community, job/career, commercial value

  11. Why Technology Changes • New problems • New opportunities • One often leads to another • Society demands change • Innovation • Emerging Technologies – new technologies that are just coming into use

  12. Analyzing Technology • Technology Assessment - The study of the effects of a technology • What is an impact? The effect a technology has on society. • What is quality? The measure of excellence of a technology.

  13. The Rate of Change • in the past, took decades or centuries • Today, , changes daily Slow rapid

  14. Exponential rate of change

  15. Six Areas of Technology • Communication: sending and receiving messages • Manufacturing: making things • Construction: building structures or shelters • Transportation: Moving people or goods • Bio-related: relating to own body or living environment • Energy/Power: ability to release energy and use it in other systems

  16. Combined Technologies • The six mentioned previously often blend together • Examples: Airplanes

  17. Technology and Human Knowledge • All the subjects in school relate to technology • How? • Technology & Science • Technology & Math • Technology and Language Arts • Technology and Social Studies

  18. Technological Literacy • Having an understanding of technology • Technological literacy goes beyond just using a technology, but understanding how it works, how it is made, how it impacts us. • All of the above must be considered when thinking critically about a technology.

  19. History of Technology • Humans have always used technology • Solving problems and meeting needs • ERAs of Technology: • Agricultural Age • Industrial Age • Information Age

  20. History cont’d • The technology of the society has been dependent upon the area and needs of the people • Examples: • Tigris-Euphrates Valley • Egyptians • Greeks and Romans • Maya • China

  21. Three Significant Eras -TIME • Agricultural Age (10,000 BC – 1750s) • Includes Stone, Bronze, and Iron Ages • Industrial Age (1750s – 1950s) • Information Age (1950s – Present)

  22. Technological focus Agricultural Age Emphasis on past Industrial Age Emphasis on present Informational Age Emphasis on future

  23. Resources Agricultural Age Land, trees, muscle Industrial Age Capital, steel, fossil fuels Information Age Information, synthetics, electricity

  24. Products & Production Agricultural Age Food, fiber, farming Rural Industrial Age Material goods, factories Urban Information Age Information, laboratories Rural & Urban

  25. Social Structure • Agricultural - Decentralized, monarchy, aristocracy, dictatorship • Industrial - Centralized, representative democracy • Information - Decentralized, participatory democracy

  26. Financial Resources • Agricultural - Decentralized banking, barter • Industrial - Centralized banking • Information - Decentralized banking, new financial institutions

  27. Work & Education Agricultural Age Physical, on-the-job Industrial Age Physical/Mental, formal education Information Age Mental, formal education, lifelong learning
