But the construction of the narratives implies the need to resort to models,
empirical results, reviews, constructs, and materials from the history of science
sensu stricto, i.e. in meaning 3. Didacticians of science and as science teachers are
not professional historians of science; therefore, they need to resort to work done by
historians, especially those who are sympathetic to the issues and problems of
science education. They then need to perform a didactical transposition on
historians’ work, giving priority to educational goals, even when this means
introducing a certain amount of ‘noise’ in the process.
