Angeloudi, Anastasia; Papageorgiou, George; Markos, Angelos – Science Education International, 2018
The study explored the possibilities to improve students' argumentation ability concerning factors that affect dissolving, through the implementation of two versions of a teaching scheme, with and without particle theory. The participants (age range 10-11, n = 27) belonged to two fifth-grade classes of a primary school in Northern Greece. Data…

Papageorgiou, George; Amariotakis, Vasilios; Spiliotopoulou, Vasiliki – Chemistry Education Research and Practice, 2017
The main objective of this work is to analyse the visual representations (VRs) of the microcosm depicted in nine Greek secondary chemistry school textbooks of the last three decades in order to construct a systemic network for their main conceptual framework and to evaluate the contribution of each one of the resulting categories to the network.…

Zarkadis, 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…

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…

Papageorgiou, George; Markos, Angelos; Zarkadis, Nikolaos – Science Education International, 2016
This work investigates the formation of particular student profiles based on of their ideas relating to basic characteristics of the atom. Participants were secondary students of 8th, 10th and 12th grades from Northern Greece (n = 421), with specific cohort characteristics e.g. age, grade and class curriculum, and individual differences, e.g.…

Kypraios, Nikolaos; Papageorgiou, George; Stamovlasis, Dimitrios – International Journal of Environmental and Science Education, 2014
In this study, students' understanding of chemical changes was investigated in relation to four individual differences, related to logical thinking, field dependence/independence, convergence and divergence thinking. The study took place in Greece with the participation of students (n = 374) from three grades (8th, 10th and 12th grades) of…

Papageorgiou, George; Stamovlasis, Dimitrios; Johnson, Philip – Journal of Science Teacher Education, 2013
One hundred and thirty Greek primary school teachers participated in a study, where the effectiveness of a specially designed intervention on chemical changes was tested. The study took place in the wider context of an in-service training course where the key feature was an innovative approach based on the concept of a substance and its…

Stamovlasis, Dimitrios; Papageorgiou, George; Tsitsipis, Georgios – Chemistry Education Research and Practice, 2013
Research in cognitive psychology and science education has acknowledged two antagonistic theoretical perspectives concerning students' knowledge. One perspective considers students' knowledge as coherent or theory-like, explaining the learning process in terms of framework theories and stable mental models, whereas the other considers it…

Stamovlasis, Dimitrios; Tsitsipis, Georgios; Papageorgiou, George – Chemistry Education Research and Practice, 2012
In this study, structural equation modeling (SEM) is applied to an instrument assessing students' understanding of the particulate nature of matter, the collective properties and physical changes, such as melting, evaporation, boiling and condensation. The structural relationships among particular groups of items were investigated. In addition,…

Stamovlasis, Dimitrios; Tsitsipis, Georgios; Papageorgiou, George – Chemistry Education Research and Practice, 2010
This work uses the concepts and tools of complexity theory to examine the effect of logical thinking and two cognitive styles, such as, the degree of field dependence/independence and the convergent/divergent thinking on students' understanding of the structure of matter. Students were categorized according to the model they adopted for the…

Papageorgiou, George; Grammaticopoulou, Maria; Johnson, Phil Michael – International Journal of Science Education, 2010
Thirty-six pupils from three sixth-grade classes (ages 11/12, n = 75) in Greece were interviewed pre- and post-intervention in a piece of research on explanations of chemical phenomena. Software concerning chemical phenomena was incorporated in a teaching scheme, where the particle theory was used. After a 13 hour intervention, pupils'…

Johnson, Philip; Papageorgiou, George – Journal of Research in Science Teaching, 2010
In response to extensive research exposing students' poor understanding of the particle theory of matter, this article argues that the conceptual framework within which the theory is introduced could be a limiting factor. The standard school particle model is characterized as operating within a "solids, liquids, and gases" framework.…

Papageorgiou, George; Stamovlasis, Dimitrios; Johnson, Phil Michael – International Journal of Science Education, 2010
This paper presents a study concerning Greek primary school teachers' (n = 162) ideas about the particulate nature of matter and their explanations of physical phenomena. The study took place during an in-service training course where the effectiveness of a specially designed intervention was tested. A key feature was an approach based on the…

Tsitsipis, Georgios; Stamovlasis, Dimitrios; Papageorgiou, George – International Journal of Science Education, 2010
In this study, students' understanding of the structure of matter and its changes of state such as melting, evaporation, boiling, and condensation was investigated in relation to three cognitive variables: logical thinking (LTh), field dependence/independence, and convergence/divergence dimension. The study took place in Greece with the…

Papageorgiou, George; Johnson, Philip; Fotiades, Fotis – Research in Science & Technological Education, 2008
This paper reports the findings of a study exploring the use of a software package to help pupils understand particulate explanations for melting and evaporation below boiling point. Two matched classes in a primary school in Greece (ages 11-12, n = 16 and 19) were involved in a short intervention of six one hour lessons. Covering the same…
