What
3.4 Internet - page 29
The use of the internet for activities such as e-commerce, academic research and social networking can
raise ethical issues and have positive or negative social impacts. These may include exposure to desirable
materials, cyber-bullying, e-fraud, improved communication between individuals and groups, intellectual
property theft, plagiarism, spamming and the global dissemination of ideas. Students are expected to
discuss, where appropriate, possible solutions to a specified problem and evaluate their effectiveness.
Possible scenario
A school is considering using the internet to enhance the learning opportunities of its students. Before
making a final decision it intends to obtain an outline of the different facilities available. It must also consider the potential problems of opening this “window on the world”. Where appropriate, the ITGS student should investigate different environments to experience the range of available learning opportunities.
This may include research using different collaborative websites, educational websites or online sources of
information.
