Online Tools for Assignment

Introduce useful online tools that may help to prepare your assignment.

Online References

Online references are helpful tools for you to gain a board overview of a topic. You can understand the key issues, history, and sometimes, latest debates on a topic without going through dozens of books, journal articles, and other materials. This can help you to develop a mind map on a topic and learn keywords and terminologies for further research.

For example, how well do you understand the topics below? Try to use the following tools to learn more.

  • Palliative care
  • Crytocurrency
  • Prisoner's dilemma
  • Nazca lines
  • Dark tourism
