  • 1. Technology in Society M4 Computing – Lesson 2
  • 2. Introduction
    • Today we are going to look at the difference technology has made to all of our lives.
    • Consider the difference technology has made to the fields of medicine, travel, military, education, communication and entertainment.
  • 3. What is Technology?
    • Being able to use tools and crafts to improve how we control and adapt with our natural or man-made environment.
    • In human society today, technology is a result of science and engineering .
  • 4. History
    • Technology has been around as long as the human race. From early spears used for hunting to the use of fire as a source of energy.
    • The wheel was an early technological breakthrough, allowing human kind to travel and transport goods.
    • Within the last few thousand years humans discovered they could use metal and wood to improve their standard of life.
  • 5. Modern History
    • In more modern times we have created more usable and complex technology such as the clock, the engine, the electric motor, the radio and the computer.
    • Consider the difference in today's society, due to massive advances in technology, as recent as 50 years ago.
    • We will now look in detail at some of those advances.
  • 6. Medicine
    • Scientific research has been greatly improved by the use of the technology.
    • Data can be analysed more accurately and faster, allowing for improved medical care.
    • Patients can be treated quickly and expertly.
    • Important technology in the medical field:
      • Keyhole surgery
      • Brain scanning
      • Online education about health and safety for people in poorer countries.
  • 7. Keyhole Surgery
  • 8. Travel
    • Technology has enabled people to be able to visit places in the World they had never previously been able to visit.
    • To travel across the world 200 years ago would have taken months rather than hours, as it does today.
    • Cars and motorbikes are now affordable thanks to advances in technology.
    • Bus, train and air travel is getting cheaper and cheaper.
  • 9. Military
    • Weapons and technology used for monitoring or spying on people has changed the face of war.
    • Nuclear technology and satellites are 2 of the major differences.
    • We can monitor (spy on) the whole world from a few satellites in space.
    • Not all technology has benefited human kind. Modern weapons are now capable of killing millions of people in one go.
  • 10. Education
    • Computers have helped make education more interesting and easier for students.
    • Research can be carried out in minutes thanks to computers and the internet.
    • Students can learn about different cultures, share experiences and take virtual tours of places far away.
    • Students can now study at home, using email, web pages and online education courses. Vital for countries with poor educational services.
  • 11. Entertainment
    • 50 years ago there was no Nintendo, no Play Station, no X Box and no internet. What did students do after school?
    • Think of the time we spend today on our mobile phones, text messaging or chatting on the internet.
    • DVD players, Satellite and Cable TV and mp3 music players are all very recent technological innovations.
    • Karaoke, cinemas and even sporting activities are all more accessible to people in recent years.
  • 12. Communication
    • We can now communicate with people all over the world in a matter of seconds, just by switching on our PCs and logging onto the internet.
    • Mobile phones have made it easier to keep in touch with friends, family and people we work with.
    • With the latest mobile phones we can log onto the internet, send emails and even have video chat!
    • Even as little ago as 30 years communication to overseas countries was limited to writing letters. Today this is known as snail mail!
  • 13. Today's Task
    • Your task today is to work in groups of 3 students and complete a Power Point presentation.
    • I want you to select an example of technology that in your opinion has changed the way we live today.
    • Please tell the rest of the class:
      • Why your chose your subject.
      • Some information about this technology.
      • How this technology has helped changed the world.
      • What life was like before this technology.
      • The future?
  • 14. Today's Task
      • Examples of technology that have helped shape modern society:
        • Internet
        • Mobile Communications
        • Computers
        • Television
        • Aircraft
        • Motor Vehicles
  • 15. Today’s Task
    • You will be presenting at the beginning of next lesson.
    • This presentation will count towards your pre-mid term mark.
    • I want to see every member of each group speaking.
    • I want to see your own work, not information cut ‘n’ paste from the web!
    • Finally – you must upload your slideshow to the webpage.
