Open-ended problem solving in school chemistry: A preliminary investigation

This paper uses a new set of 14 open-ended problems, designed for 14-17-year-old pupils studying chemistry, to attempt to gain some initial insights into the ways pupils solve open-ended chemistry problems. The emphasis is on how concepts and linkages between concepts influence success in solving such open-ended problems. Pupils worked in groups of three attempting to solve the problems and were encouraged to talk freely, to make notes of their progress, and to note their agreed answers. Evaluation sheets were also completed individually by the pupils after each problem. By studying the interactions between pupils by means of written materials, observation and audiotapes, it was possible to build up a picture of the way the pupils approached the problems and to explore some of the reasons for difficulties they experienced. In the light of the evidence, it is suggested that creating the links between 'islands' of knowledge is an important skill in solving open-ended problems and that this skill is not easily achieved by pupils at these ages. The notion that problem solving is a generic skill which can be taught is questioned.
