Abstract

“Didactic transposition” or “Didactic content transformation” refers to the transformation of complex or specialized expert higher knowledge into teachable knowledge, so that it can be taught effectively to students. In the present study, two publications / sources of knowledge (which were used as "primary sources") were initially selected and a set of topics/themes related to chemical bonding was compiled. Then a total horizontal analysis of the above two publications was carried out, leading to a list of themes (17 "points"), in which significant similarities as well as differences were observed. Having as a "guide" the first two sources, the analysis of four additional sources, two books in English and two Greek schoolbooks followed. From the specific books, the chapters related to chemical bonding were studied and a comparative analysis/comparison of these books was made based on the 17 "points" that resulted from comparison of the first two sources.
