Παρουσίαση και Αξιολόγηση της Μελέτης του Χημικού Δεσμού στη Διεθνή Βιβλιογραφία

Abstract

In continuation of previous research studies concerning (a) the presentation of the chemical bond chapter in secondary education, (b) the assessment of students' and university students' understanding of the chapter, and (c) the misconceptions associated with the study of chemical bonding, an analysis was conducted on how this chapter is presented in foreign literature.n this study, the presentation of chemical bonds in nineteen General Chemistry books, both university-level and non-university-level, was evaluated. The evaluation included the following stages: a. A description and examination of the way the chemical bond is presented in the respective chapters of each book individually.b. A comparative analysis of all the books together, based on specific criteria. The conclusions drawn from the comparative evaluation of university-level General Chemistry textbooks and international secondary education chemistry books lead to the following findings: The way chemical bonds are presented in international General Chemistry books shares many common features with Greek textbooks, which likely results in the formation of similar misconceptions. Examples include the association of electronegativity with covalent bonds, the linkage of Coulomb forces with ionic bonds, and the lack of connection between bond concepts and physical states, references to intramolecular bonds and intermolecular forces etc. However, differences were also observed, such as the study of bond continuity, even if only through brief mention, or the inclusion of metallic bonding studies.
