Direct linkStavrou, Dimitris; Michailidi, Emily; Sgouros, Giannis – Chemistry Education Research and Practice, 2018
Introducing Nanoscience and Nanotechnology (NST) topics into school science curricula is considered useful for an in-depth understanding of the content, processes and nature of science and technology, and also for negotiating the social aspects of science. This study examines (a) the development of an inquiry-based Teaching-Learning Sequence (TLS)…

Taber, Keith S.; Tsaparlis, Georgios; Nakiboglu, Canan – International Journal of Science Education, 2012
Previous research has reported that students commonly develop alternative conceptions in the core topic of chemical bonding. 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…

Papageorgiou, George; Markos, Angelos; Zarkadis, Nikolaos – Chemistry Education Research and Practice, 2016
The current study aims to investigate students' representations of the atomic structure in a number of student cohorts with specific characteristics concerning age, grade, class curriculum and some individual differences, such as formal reasoning and field dependence/independence. Two specific task contexts, which were designed in accordance with…

Pappa, Eleni T.; Tsaparlis, Georgios – Chemistry Education Research and Practice, 2011
One way of checking to what extent instructional textbooks achieve their aim is to evaluate the questions they contain. In this work, we analyze the questions that are included in the chapters on chemical bonding of ten general chemistry textbooks. We study separately the questions on intra- and on intermolecular bonding, with the former…

Tsaparlis, Georgios; Papaphotis, Georgios – International Journal of Science Education, 2009
This study tested for deep understanding and critical thinking about basic quantum chemical concepts taught at 12th grade (age 17-18). Our aim was to achieve conceptual change in students. A quantitative study was conducted first (n = 125), and following this 23 selected students took part in semi-structured interviews either individually or in…
