Logical language,natural strategies and the teaching of science

The role of formal logic in the development and investigation of science education is analysed. Firstly, the way in which teachers use language, logical and otherwise, is described and the necessary use of logical relations in the learning of abstract concepts and ideas is investigated. The conclusions drawn from the literature indicate that learners have great difficulty in comprehending the normal logic implied in ordinary words such as ‘because’ and ‘therefore’, and that the more difficult the context, the more likely it is that even the most common logical argument will be misunderstood. Less common logical words may be misunderstood by a majority of typical pupils in science lessons.

Secondly, the development of efficient cognitive processes in the context of science curricula is investigated. The conclusion drawn from literature describing experiments (rather than suggestions based more in philosophy) suggests strongly that formal logics probably have little to offer science educators. It is argued that until science teaching starts to base itself more on ‘natural strategies’, in much the same way as it is now looking seriously at ‘alternative frameworks’ as the basis for concept development, process development in science teaching will not seriously affect the ability of most pupils to solve either scientific or everyday problems more efficiently.
