The World of the Future

Many of the technological innovations we are now starting to foresee will undoubtedly make an impact on the world in the future. Our goal is not just to try to understand how these innovations will shape up the future but, most importantly, the impact they will have on individuals and societies.

Choose five technological innovations that you think will have a significant impact on the future, and for each of them, working in pairs, write in your blog the following considerations:

-          A description of the technological innovation itself, including the link to an Internet reference on it, and its current status of development.

-          How it is expected to further develop in the future and any possible limitations to such progress.

-          A detailed description of the expected impact of this technological innovation on life in the future.

Surveillance

One of the topics that has garnered greater attention lately related to the impact of technology is that of electronic surveillance, understanding by it the application of modern technologies that can eventually compromise individual privacy of citizens, both by the state or other organizations.
After researching the topic, working in pairs, the assignment consists of writing an article for an online magazine entitled:

"Advances in technology are increasingly compromising citizens' privacy: how to be aware of tech intrusions to your private life".

The article should be at least of 1,200 words and be posted on your blogs.

IB Application to Scenarios

Strand 2: Application to specific scenarios

The scenarios listed here are divided into themes as an organizational tool. Examination papers assess scenarios related to these themes. Individual examination questions may address one, some, or all of the themes.

•            Every theme must be studied.

•            Every topic within each theme must be studied.

•            Each topic must be taught using real examples. Some of the examples shown in the tables suggest possible approaches for study.

•            Students will be expected to apply their knowledge from the topics taught in class or researched independently to the stimulus material in the externally assessed components. This may include discussing ethical issues and social impacts as well as demonstrating an understanding of the IT systems involved.

•            For each of the scenarios addressed, students will be expected to identify relevant stakeholders and to discuss, where relevant, potential stakeholder conflict.

2.1 Business and employment

Topic	Examples
Traditional businesses	Banks, including ATM (automatic teller machines), EFT (electronic funds transfer), hotels, supermarkets, travel agencies.
Online businesses (e-commerce)	Working practices such as teleworking and home working.
Transportation	Airline reservation systems, navigation, package tracking, traffic control systems, IT systems in cars.

The coverage of business and employment should address the IT systems that exist as well as the ethical issues and social impacts that arise from the increased use of information technologies for both employers and employees. Students should be aware of the range of different business environments, ranging from a traditional (offline) business to businesses that are exclusively online.

2.2 Education and training

Topic	Examples
Distance learning over large areas	Hospitals, prisons, retirement homes, schools.
Use of IT in teaching and learning	Educational software, online research and forums, virtual learning environments (VLE), e-books, Web 2.0 educational networks, use of mobile devices, game-based learning, fully immersive environments, filtering and monitoring of students’ internet use, 1-to-1, m-learning.
Hardware and network technologies in the classroom	Laptop computers, handheld devices, interactive whiteboards.
Topic	Examples
Provision for special needs	Inclusive software, Braille keyboards, accessibility.
School administration	Record-keeping of staff and finances, libraries, student records, EDI (electronic data interchange).

The development of new IT systems is revolutionizing the delivery of education and training. Technological advances have led to an increase in the dependency of students, staff and administrators on the supporting IT systems.

2.3 Environment

Topic	Examples
Modelling and simulations	Climate change, forecasting natural events or demographic changes.
Data logging	Sensors, probes, real-time data collection.
Satellite communication	Remote sensing devices, satellite imagery, tagging.
Mapping, virtual globes	Geographic information systems (GIS), global positioning systems (GPS), cell/mobile phone tracking, online journey planning, online maps.
E-waste	Development, disposal and recycling of IT equipment, monitoring organizations such as the Basel Action Network.
Resource depletion	Use of non-renewable resources for manufacturing components, electrical consumption of IT systems.

The environmental theme covers a wide range of topics. The increasing processing capability of mobile devices has enabled almost universal access to information, but the increased number of devices has impacted on health and the environment.

2.4 Health

Topic	Examples
Diagnostic and therapeutic tools	Surgery, prosthetic devices, diagnostic technology, rehabilitation, patient monitoring, individualized IT solutions for disabled people, accessibility.

Hardware, software and networks	Portable digital devices and their ability to remotely control other devices, IT-enabled appliances.

The growth of the internet and the ability to transfer information globally in real time has revolutionized the way in which increasing numbers of people live. The global online society, the development of English as the dominant online language, and the constant availability of information may lead to a homogenization of peoples, with some cultures being subsumed into others or lost. 

2.6 Politics and government

Topic	Examples
Political processes	Online campaigning, voting, lobbying, fund-raising and advertising.
Government information sites	For example, travel warnings, tourist information, environmental information and warnings, government policies, city government websites.

The importance of IT is becoming increasingly evident in political campaigns. With increased amounts of information available to governments, ethical issues relating to its possible misuse are becoming more and more important.

Blog on application to specific scenarios

In order to tackle this strand, we will divide the work so as to find resources that can later be used to study. To do that, we will work on a multi user blog.

• Initially, send me an email with your preferred email address to become an author in the blog. You will receive an invitation to join the multiuser blog http://itgsoptions.wordpress.com  
• After joining as an author, your objective is to create one blog entry for each of the themes that you chose. These posts should be about articles or links to Internet sites that relate to these themes and should include:
• URL of the site
• Justification of why the authors are valid
• Short summary of why the site is relevant to the topic studied.

Do not forget to categorize each post.

21st Century Business

Like no other area, technology has impacted businesses very significantly, and resulted in increased productivity. However, there are issues associated with the generalized use of technology in the workplace that have affected both positively and negatively individuals and society.

We will analyze the influence of technology in business and how it can affect jobs. You are a consultant and you have been hired by a client to develop the technological support for his new firm. This is a 2000-employee retail store that sells goods direct to the general public, and will have branches at various shopping centers within Buenos Aires. Your client is set on incorporating the latest available technology to his firm and as such, it is your job to provide him with the latest advances in the following areas:

- Transportation and logistics: storage and transport of goods, inventory control, purchase processing.
- Employment: electronic employee monitoring, payroll processing, ergonomics and health, job obsolescence and retraining, online job search, employee surveillance.
- Banking and finance: ATMs, Internet banking and brokerage, electronic cash, insurance.
- E-commerce: teleshopping, online marketing, data mining,
- Retailing: advertising, media.

For each of these areas, you must find at least one application that will position his firm on the cutting edge. By creating a presentation, you will highlight for each of these applications:
- Characteristics and main functions.
- How it can help boost productivity and gain efficiency.
- Eventual ethical or social issues associated with their use, concerns that employees might have.

Create a Powerpoint presentation that details the applications that you use for each area , addressing each of the 3 points above.
