Direct linkDimopoulos, Kostas; Koulaidis, Vasilis; Sklaveniti, Spyridoula – Research in Science Education, 2005
This study aims at presenting a grid for analysing the way the language employed in Greek school science textbooks tends to project pedagogic messages. These messages are analysed for the different school science subjects (i.e., Physics, Chemistry, Biology) and educational levels (i.e., primary and lower secondary level). The analysis is made…

Apostolou, Alexandros; Koulaidis, Vasilis – Research in Science & Technological Education, 2010
The aim of this paper is to study the epistemological views of science teachers for the following epistemological issues: scientific method, demarcation of scientific knowledge, change of scientific knowledge and the status of scientific knowledge. Teachers' views for each one of these epistemological questions were investigated during…

Peer reviewedDimopoulos, Kostas; Koulaidis, Vasilis; Sklaveniti, Spyridoula – Research in Science Education, 2003
Analyzes the pedagogic functions of visual images included in school science textbooks and daily press articles about science and technology. Indicates that the science textbooks (a) use 10 times more images, (b) use more images so as to familiarize their readers with the specialized techno-scientific content and codes, and (c) tend to create a…

Peer reviewedChristidou, Vasilia; Koulaidis, Vasilis; Christidis, Theodor – Research in Science Education, 1997
Examines the relationship between children's use of metaphors and their mental models concerning the ozone layer and ozone layer depletion. Results indicate that the way children represent the role and depletion of ozone is strongly correlated with the types of metaphors they use while constructing and/or articulating their models. Also discusses…

Peer reviewedChristidou, Vasilia; Koulaidis, Vasilis – Research in Science Education, 1996
The views of 40 primary students on ozone and its depletion were recorded through individual, semi-structured interviews. The data analysis resulted in the formation of a limited number of models concerning the distribution and role of ozone in the atmosphere, the depletion process, and the consequences of ozone depletion. Identifies five target…

Peer reviewedKoulaidis, Vasilis; Tsatsaroni, Anna – Research in Science Education, 1996
Discusses some of the available frameworks for the pedagogical analysis of school science textbooks. Discusses three approaches to the analysis of science textbooks: the sociocognitive, the sociolinguistic, and the socioepistemic. Considers the relative merits of the third approach using some examples from Greek science textbooks. Contains 18…
