Introduction
The 21st century challenges educators to prepare students to cope with complex and unforeseeable
changes. Education must provide them with the attitudes, knowledge and skills they require as active
members of an information society. This shift in paradigm has been the driving force behind Singapore
education till today, aiming to nurture students into active learners with critical thinking skills while
developing a creative and critical thinking culture because learning how to learn is fundamental to
economic and personal success in the information age (Doyle, 1994).
