Schizas, Dimitrios; Psillos, Dimitris; Stamou, George – International Journal of Science Education, 2023
The present study investigates how Greek in-service secondary education biology teachers understand the unique features of school biology and physics when considering the biological theoretical edifice and method. Our theoretical framework focuses on important differences that exist between the neo-Darwinian and Newtonian worldviews, while our…

Manou, Leonidas; Spyrtou, Anna; Hatzikraniotis, Euripides; Kariotoglou, Petros – International Journal of Science and Mathematics Education, 2022
Nanoscience and nanotechnology (NST) focus on the creation and the exploration of materials' properties at the nanoscale. The estimations about the impact of the field on our daily life, the industrial demands for ensuring skilled workforce, and the need to form a nano-literate citizenry have triggered the incorporation of aspects of this…

Schizas, Dimitrios; Papatheodorou, Efimia; Vezagkou, Traiani; Stamou, George – International Journal of Science Education, 2020
Science and environmental educators implicitly presuppose that the ecosystem per se is clearly defined and consider learners' misunderstandings to be incorrect scientific interpretations of uncontested knowledge content. The present study, however, explores how in-service secondary education Greek biology teachers address the topic of 'ecosystem…

Pierratos, Theodoros; Koumara, Anna – Primary Science, 2020
In this article, a series of activities on explicit teaching of specific aspects of the 'nature of science' are presented. The authors explore teaching the nature of science through inquiry-based activities on electric circuits. The activities concern classification of objects as conductors or insulators and took place in three classes of 4th…

Koumara, Anna; Plakitsi, Katerina – World Journal of Education, 2020
The present study examines the integration level of the Nature of Scientific Knowledge in secondary school science classes in Greece. The research was designed and organized on the basis of the Cultural-Historical Activity Theory. The activity system of the researchers, who use the proper tools each time, are in network relations with the activity…

Mogias, Athanasios; Boubonari, Theodora; Kevrekidis, Theodoros – International Research in Geographical and Environmental Education, 2021
This study aims to add to the mapping of the presence of ocean sciences issues in national curricula and textbooks worldwide, investigating the inclusion of ocean literacy principles and their fundamental concepts in Greek primary science textbooks according to the Ocean Literacy Framework. Content analysis was implemented in both textual and…

Schizas, Dimitrios; Psillos, Dimitris – Electronic Journal of Science Education, 2019
The present study elaborates on a domain-specific approach to NOS (Nature Of Science) and employs a NOTSs (Nature Of The Sciences) agenda to investigate how Greek in-service physics teachers understand the unique features of school physics and biology. Our theoretical framework focuses on the notion of worldview and important differences that…

Kapsala, Nausica; Galani, Apostolia; Mavrikaki, Evangelia – Center for Educational Policy Studies Journal, 2022
The nature of science describes what science is, how it works, and its interactions with society under the perspectives of philosophy, history, sociology, and psychology of science. Understanding it is an essential aspect of scientific literacy. Given the critical role that school textbooks hold, considering what is taught and how it is taught in…

Schizas, Dimitrios; Papatheodorou, Efimia; Stamou, George – International Journal of Science Education, 2019
The present study explores how in-service secondary education Greek biology teachers understand aspects of the concept of ecosystem under the assumption that the ecosystem is an ill-defined concept. If it is to be considered a holistic entity, the ecosystem acquires its definitional features within the ecological field of systems ecology, which…

Koumara, Anna; Plakitsi, Katerina; Lederman, Norman – Science Teacher, 2022
How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Koulougliotis, Dionysios; Antonoglou, Lemonia; Salta, Katerina – International Journal of Science Education, 2021
This study aims at investigating students' awareness of green chemistry principles (GCPs) which are infused in two context-based projects that are related to socio-scientific issues, namely climate change and materials' recycling. At first, content analysis of the projects' activities showed the infusion of four GCPs. Subsequently, the students'…

Velentzas, Athanasios; Halkia, Krystallia – International Journal of Science Education, 2018
In this study, an analysis of the structure of scientific explanations included in physics textbooks of upper secondary schools in Greece was completed. In scientific explanations for specific phenomena found in the sample textbooks, the "explanandum" is a logical consequence of the "explanans," which in all cases include at…

Gegios, Theodoros; Salta, Katerina; Koinis, Spyros – Chemistry Education Research and Practice, 2017
In this study we present an analysis of how the structure and content of the Greek school textbook approaches the concepts of chemical kinetics, and an investigation of the difficulties that 11th grade Greek students face regarding these concepts. Based on the structure and content of the Greek textbook, a tool was developed and applied to…

Stavrou, 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)…

Stasinakis, Panagiotis K.; Kalogiannnakis, Michail – World Journal of Education, 2017
In this study we aim to find out whether a training program for secondary school science teachers which was organized based on the model of Pedagogical Content Knowledge (PCK), could improve their individual PCK for a specific scientific issue. The Evolution Theory (ET) and the Natural Selection (NS) were chosen as the scientific issues of…
