Abstract

To investigate 13 year old pupils' suggested aims, recognition of relevant variable, and the relationship between the suggested aim and the conclusion which is drawn by pupils, we classified experiments in textdbook into three cases: (1) Case involving dependent variable and independent variable in the title of experiment, (2) Case involving dependent variable only, where pupils can know independent variable from the content of textbook, (3) Case involving dependent variable only, where pupils hardly can know independent variable from the content of textbook. In respect of the aims which pupils suggested, the suggested aims were reduced to the title of experiment in case(1). However, the suggested aims were divided into several forms which is not relevant to the content of experiment in case (2), (3). This shows that pupils are affected by the title of experiment according to how the variable is involved in the title of experiment. This is supported by the fact that when the variable is described in the title, the suggested aim is reduced to the title of experiment. On the other hand, there was a relationship between the suggested aim and the drawn conclusion in case (1). But there was few relationships in case (2) and (3). Surprisingly, the drawn conclusion in case(1) was not consistent with the expected one because of the inappropriate experimental setting. We need to be more careful in experimental setting, pupils' cognitive ability, and openness of experiment to help pupils perform experiment successfully.
