The development of Design and Technology curricula has always been premised on the importance of the act of designing and of the value of the contingent activity of creative thinking. Despite this, there has been a great deal of uncertainty about methods for developing creative thinking abilities in design and technology students. However, the results of research from cognitive psychology, engineering and invention suggest some promising strategies for application in design and technology classes. Moreover, these strategies are emerging during a time when issues concerning ethics and values are also being raised. This paper presents a brief summary of the research into problem-solving and design. It then explores a range of creative thinking strategies, and of their possible applications in design, and goes on to argue that the strategies and settings that promote creative thinking in design and technology make the area not only one that is suitable for addressing ethics and values, but that it may be one of the major reasons for including design and technology programs in school curricula.
