1. Introduction Creativity is man's best need in all life's dimensions and a jump in his/her thinking. Creativity includes combination of known ideas. The strength of human being's brain enables him/her to enjoy talent for creativity and it is because of same talent that scope of knowledge in increasing everyday more than yesterday. Creativity is one of better specifications of human beings. In current era, one of most important goals of progressive education of world is educating creative and innovative learners (Saif, 2001). Balzac (2006) has studied neurology of creativity and has reached conclusion that creative innovations need simultaneous activity and connection of some parts in brain that are not ordinarily in a strong contact with one another. Gardner (1982) believes that creativity starts from young ages and in his view, pre-school children have a lot of creative capabilities, but when they start school, they begin learning how read and write and in order to have coordination with others, they learn how to follow and obey. That is why their creativity decreases. Therefore, we have to think of ways that will not decrease creativity in children.According to belief of most researchers, traditional methods of education not only do not help with growth of creativity, but in fact it is considered to be an obstacle (Berg, 2000). Therefore, one of main tasks of teachers is to create, as much as possible, a definite and appropriate atmosphere in classroom and take advantage of active and discovering teaching methods in classroom and help students to utilize their creative power.In Torance's (2002) idea, creativity is considered to be a process that is evolved collectively. He believes that all people are creative and it does not necessarily belong to just smart people. Creativity can be increased and/or created in different ways.

As a result, outcome of creativity is important which has to have characteristic such as innovation, value and solidarity. Another group of psychologists put an emphasis on creativity. The individuals consider it as a process of characteristics such as fluidity, flexibility and newness and believe that creative process has several stages. For example, Wallace has mentioned four stages of preparation, latency, intuition, and stability for creativity.- preparation: In this stage, all sides of problem will be taken into consideration and mentioned problem will be identified and truths related to it will be collected.- Latency: In this stage, there is some mental processes that connect new information with past ones. Some types of new organization of information take place without individual's direct awareness.- Intuition: in this stage, a pleasant idea appears which is called the aha phenomenon. At this stage, creative person will suddenly learn ideas of solutions to problem.- Stability: In this stage, idea that took place in previous stage will be evaluated to reveal its credibility or lack of it (Mirzaeeyan, 2004).Today, experts consider creativity as a fundamental knowledge for any change and innovation. According to Brolin (1999), creation of new ideas and innovative production are some of cognitive characteristics of people. …
