![]() Students commonly develop similar alternative conceptions of ionic bonding in these three different educational contexts. ![]() The study reports that students in these two contexts displayed high levels of support for statements based upon the alternative conceptual framework identified in the English context. The present study reports the use of translated versions of a diagnostic instrument to elicit the conceptions of bonding in NaCl (commonly used as the teaching example of an ionic compound) from two samples of students setting out on university courses in Greece and Turkey. Research in England has reported that students there commonly demonstrate an alternative ‘molecular’ conceptual framework for thinking about ionic bonding: in terms of the formation of molecule-like ions pairs through electron transfer, which are internally bonded, but not bonded to other ions. ![]() Previous research has reported that students commonly develop alternative conceptions in the core topic of chemical bonding. ![]()
