Download full textZarkadis, Nikolaos; Stamovlasis, Dimitrios; Papageorgiou, George – Science Education International, 2021
The present study investigated the association of students' fundamental ideas and misconceptions about ontological features of atom identity and behavior with the formation of their portrayed representations of the atomic structure. Participants (n = 421) were secondary education students in the eighth, tenth, and twelfth grades. Students'…

Zarkadis, Nikolaos; Stamovlasis, Dimitrios; Papageorgiou, George – European Journal of Physics Education, 2021
The present study investigates the effect of three neo-Piagetian constructs, namely Formal Reasoning (FR), Field Dependence/Independence (FDI) and Divergence (DIV), as well as the effect of age and gender, on students' portrayed representations of the atomic structure, considering their degree of coherence. For this purpose students'…

Direct linkZarkadis, Nikolaos; Papageorgiou, George; Stamovlasis, Dimitrios – Chemistry Education Research and Practice, 2017
Science education research has revealed a number of student mental models for atomic structure, among which, the one based on Bohr's model seems to be the most dominant. The aim of the current study is to investigate the coherence of these models when students apply them for the explanation of a variety of situations. For this purpose, a set of…
