Problem solving

Stephen and Gallagher (1983) define problem solving as “a curriculum development and delivery system that recognizes the need to develop problem solving skills as well as the necessity of helping students to acquire necessary knowledge and skills”. Simply put, it is a teaching strategy that focuses or emphasizes on the development of problem solving skills in the children.
The most obvious (but not necessarily the best) reason for teaching problem solving is to help children develop critical and creative thinking skills. Education can be more wholesome and realistic if children are more able to use their school learning in solving problems in their day to day life situations and most of the teacher are frequently suggested as to why this form of learning should be encouraged because it develop students current knowledge, It is interesting and enjoyable way to learn, challenging, it needs positive attitude towards learning, it develop sense of inquiry and research in children, it teaches thinking flexibility and creativity, teaches problem solving skills, encourage cooperative learning skills and use full way to practice skills learned by other means.
IDEAL is a mnemonic device proposed by Bransford and Stein (cited in Crowl, et al. 1997, p. 161) and it is considered to be an effective strategy of problem solving. I: Identify the problem. D: Define and represent the problem. E: Explore possible strategies. A: Act on the strategies.        L: Look back and evaluate the effects of your activities.
