IT in Modern Society: IT Professions and Open Educational Resources

Information technology is used in schools, hospitals, banks and shops. Many kinds of experts keep it working: programmers write code, designers plan screens, analysts read data, network engineers connect computers and security experts protect data. Open educational resources (OER) are lessons and books that an open licence lets you use, share and often change, if you credit the author.

🎬 Step-by-step story

  1. A small town with a school, a hospital, a bank and a shop. Each has a glowing screen. Today IT is everywhere.
  2. The makers. A programmer joins code blocks into an app. A designer draws the plan of the screen so it is easy to use.
  3. The keepers. An analyst reads numbers in a chart. A network engineer joins computers. A security expert puts up a shield for data.
  4. Open educational resources. One lesson is copied again and again and reaches many students. Count the copies.
  5. An open licence says four things: use it, share it, change it, and credit the author. Orange copies are changed versions.
  6. Free play. Pick a job to see what that expert makes, and press Copy it to share the lesson.

🤔 Common doubts, cleared

Why does a town need so many IT people?

Every school, hospital, bank and shop depends on screens and networks. They must be built, joined, protected and checked all the time.

What does a designer do if the programmer writes the code?

The designer decides how the app looks and how easy it feels, so people can use it without confusion. The programmer then builds that plan in code.

Why do we need security people if we have passwords?

Passwords are only one lock. Security specialists find weak spots, set more locks and watch for attacks, so one stolen password is not the end.

How can one lesson reach so many students?

Because digital copies cost almost nothing, an open lesson can be copied again and again. Each person who gets it may pass it on.

Why must I still credit the author if the lesson is free?

Free to use is not the same as no author. The author lets you use the work on one fair condition: tell people who made it.

Can I pick more than one IT job?

Yes. Many people change jobs or mix skills, for example a designer who also codes a little, or an analyst who learns security.

IT in society

Information technology (IT) means computers, networks and programs used to collect, store, send and use information.

IT saves time and reaches far places. It also brings new risks (stolen data) and new needs (people who can build and guard systems).

IT professions

A profession is a kind of work that needs special training. Here are common IT professions.

The makers

The keepers

New and mixed jobs

AI engineers, robotics technicians and digital marketers also use IT. Many jobs outside IT (doctor, farmer, teacher) now need IT skills.

How to choose

  1. Notice what you like: building, solving puzzles, drawing, numbers, helping people.
  2. Try a small project (a school website, a chart of class marks).
  3. Learn step by step: maths, English, logic and a programming language.

Open educational resources (OER)

Open educational resources are teaching and learning materials (lessons, books, videos, tests) that anyone may use for free, and often share and improve.

What makes them open

An open licence gives permission in advance. A well-known family is Creative Commons. Common permissions:

Some licences add rules, such as "no commercial use" or "share your changes under the same licence". Always read the licence sign.

Examples

Why they matter

Costs fall, teachers can adapt lessons to their students, and knowledge reaches villages and small schools. But check the quality and the date, and remember that free to view is not the same as free to copy. Without an open licence, copying is not allowed.

Try it

  1. In the 3D press each job button. Which job would you like to try, and why?
  2. List three IT people who helped you today (for example the person who made your school app).
  3. Find an open lesson online. Find its licence sign. Write which of use, share, change and credit it allows.
  4. Use a free picture with credit in a poster. Write the credit line under it.

Key formulas and definitions

Worked examples

1. A school wants a new app for attendance. Name three IT professionals who might work on it and what each does.

A designer plans the screens so teachers can mark attendance fast. A programmer writes the code. A security specialist protects student data. A tester can be a fourth to find mistakes before the school uses it.

2. A teacher finds a science lesson with an open licence that allows use, sharing and changes with credit. She translates it into her language and adds local examples. May she hand it out to other schools?

Yes. The licence allows sharing and changing. She must credit the original author and follow any extra rule on the licence sign.

3. A student copies a nice lesson from a website that has no licence and puts it on his own site. Is this correct?

No. Without an open licence the author keeps all rights. He should ask permission, or link to the page, or use an open lesson instead.

Common mistakes

Practice quiz

1. Who writes the code of an app?
2. Who protects data and systems from attack?
3. What are open educational resources?
4. Which is almost always required when you use an open resource?
5. Who finds patterns in large data to help people decide?

Practice: answer these yourself

Frequently asked questions

Which IT job should I choose?

Choose by what you enjoy: building things, solving puzzles, drawing, or working with numbers. Try small projects first. Skills like maths, clear English and logical thinking help in all IT jobs.

Can I change an open lesson?

Often yes, if the licence allows changes. You must credit the author and follow the licence rules. Some licences say that you must share your changed version under the same licence.

Is everything on the Internet open to copy?

No. Most things have an author who keeps the rights. Use a thing only if it has an open licence that allows your use, or if you have permission.
