Information Technology in a Global Society

ITGS textbook cover Information Technology in a Global Society for the IB Diploma is the first textbook designed specifically for the IB ITGS course. Unlike the general computer science textbooks currently used by many ITGS teachers, this book is written specifically with the IB ITGS course requirements in mind, and covers all components of the new ITGS syllabus (first exams May 2012), including the Higher Level (HL) topics. It is fully illustrated with over 300 photographs, diagrams, and charts.

The book is available from,, and a variety of book shops.

This site supports the book with additional lesson plans, exercises, links to useful software, and other ITGS teaching resources. You can also view a detailed table of contents and download a free sample chapter.

RoboRace is a project to develop a self-driving racing car. The original aim was to have ten teams of cars competing during the 2016/2017 Formula E championship for electric cars. However, that goal now seems rather optimistic. Nevertheless, the RoboRace YouTube channel has some useful videos documenting the development process and some of the difficulties encountered.

Internet Languages

Languages and the Internet

The cultural diversity that the Internet enables can have both positive and negative social and cultural impacts. The dominance of the English language can lead to equality of access issues for users who only speak other languages. Similarly, some organisations such as UNESCO fear that as English and Western culture in general dominate the Internet, older, less common languages and cultures may be pushed to the sidelines and eventually become extinct. Linguistic diversity and multilingualism on Internet discusses this possibility with clear examples.

A report by the UN, How Much of the World Has Regular Internet Access?, found that only 5% of the world's languages were represented online.

On the other hand, the Internet itself can also being used to protect and preserve languages. The Endangered Languages project is one example- its goal is to record samples of these languages for future generations.

Internet Statistics

Internet Statistics

Internet World Stats is a good site for interesting and often surprising statistics about Internet access and use across the world. It includes pages on penetration rates, languages, and much more, which provide a useful background for study the digital divide and cultural diversity.

Other sites include statistics about the language of websites and device statistics which also make interesting reading.

It is easy to assume that many or most people have Internet access. However, this is far from the truth. According to a recent report in the Telegraph, more than half the world (57%) still do not have Internet access.

How Much of the World Has Regular Internet Access? is a UN report which reveals some interesting trends - including significant gaps between the percentage of women who have Internet access globally and the percentage of men. In some areas the difference is as high as 50%.

Even in more developed countries, there can still be a digital divide: the Pew Research Center claims 15% of Americans do not have Internet access - with age and lack of finance tending to be a barrier to uptake.

Of course, as with any statistics we should be careful to understand how, when, and by whom the measurements were made, as the Internet can evolve very quickly.

Database security issues

Database security issues

Unfortunately significant database breaches tend to make the headlines every few months. Examples include:

August 2016: Personal details of up to 2.4 million people may have been stolen from Carphone Warehouse

August 2016: Accounting and payroll software company Sage said its systems were compromised and data for 280 UK businesses may have been stolen.

August 2016: Yahoo investigated a data breach in its MySpace and LinkedIn divisions, after it was claimed 200 million Yahoo IDs were stolen.

June 2016: The personal details of 112,000 French police officers became publicly available after a disgruntled worker for a support company uploaded them to Google Drive.

June 2016: Chinese hackers were suspected of stealing the details of almost 4 million people from the Office of Personnel Management (OPM), a branch of the US government

April 2015: the US Office of Personnel Management revealed a hack had exposed 1.1 biometric records to unauthorised access. In September 2015 this number was increased to 5.6 million fingerprints.

The textbook details several cases of lost data by the British government, including the Ministry of Defence's loss of personal data of 600,000 people. Many organisations have lost data, including 132 UK councils, the National Health Service (memory stick left on a train), and even  NASA (stolen laptop). Meanwhile, Computer World reports that over half of UK firms have lost data in security breaches.

Not to be outdone, the HMRC lost sensitive personal data of 25 million people after sending it out, unencrypted, on two CDs - which were subsequently lost.

Under the Data Protection Act, companies can be fined for losing sensitive data, and in a few cases this has happened: Zurich Insurance was fined £2.3m in 2010, Shopacheck was fined for losing data on over half a million customers in 2012, and the NHS was fined £200,000 for losing the data of 3,000 patients in 2013.

Eye in the Sky DVD

Eye In The Sky | | Instant Video

Eye in the Sky is a military-legal drama, starring Helen Mirren as a Colonel at the centre of a Unmanned Aerial Vehicle (UAV) attack on terrorists in Nairobi, Kenya. Although much of the film focuses on the ethical questions surrounding premeditated strikes and collateral damage, there is a strong undercurrent of ideas relating to drone technology and the opportunities is creates. The film also features cutting edge technology such as miniature drones (including a hummingbird and a tiny beetle), which do not exist at the moment but have certainly been mooted. These inclusions makes Eye in the Sky a useful discussion starter for ITGS lessons.

Internet trends

State of the Internet: Internet visualisations

State of the Internet is an excellent page from Akamai features interactive charts to help students visualise Internet trends. Students can view a global map of Internet speeds (which holds a few surprises) and customize the graphs to show data and changes from which countries and time periods they want. The page also contains information about threats and security trends.

This is a great way of examining potential digital divides. A good ITGS lesson idea might be to have students discuss which areas of the world might have the fastest and slowest (or non-existent) Internet access, justify their assertions, and then use this tool to check their accuracy.
