Opportunities to learn related to the use of quantitative reasoning to solve higher-order real-world applications that reflect the messy nature of the world are scarce and vary across countries. Those experiences are essential to the development of quantitative literacy. This literacy, like that related to language, is critical for all children.…

To solve problems, specific skills are needed. Critical thinking can help develop such skills. It can contribute to improving problem-solving skills, developing communication skills and cultivating decision making skills. Critical thinking is considered to be a key pedagogical goal in education. Education of informatics and critical thinking have…

Building on previous research concerning the archaeological narratives of Greek history textbooks, this study investigates the impact of these studies on schoolchildren's historical ideas. In the context of these narratives, the article addresses two significant landmarks of Greek antiquity, namely the Mycenaean civilization and the Acropolis of…

Introduction: Religious textbooks are always at the front of the Greek educational reality, following the broader tendency of a school study grounded on textbook culture. The present paper focuses on the visual structure of the Greek secondary religious textbooks (in the three grades) and answers the following questions: What kinds of visuals are…

The ability to relate mathematics teaching to real life is the common goal of many countries' mathematics curriculum National Society for Experiential Education's (NSEE) [2011] "Eight Principles of Good Practice for All Experiential Learning Activities." (intention, originality, planning, clarity, monitoring and evaluation, reflection,…

Reading mathematical texts is closely related to the effort of the reader to understand its content; therefore, it is reasonable to consider such reading as a problem-solving activity. In this paper, the Principle of Mathematical Induction was given to secondary education students, and their effort to comprehend the text was examined in order to…

According to the Next Generation Science Standards, science instructional materials can be efficient as long as they integrate three dimensions: science and engineering practices, crosscutting concepts and disciplinary core ideas. However, research investigating the integration of these three dimensions in the content of school science textbooks…

School textbooks are media of communicating a large amount of knowledge and teachers rely their teaching practices and schedule their instructions upon them. Except for knowledge on school subjects, textbooks also promote various ideological messages, including gender representations. This study explores gender representations in the Greek primary…

Existing research suggests that young children can develop a partial understanding of the equal sign as an operator rather than as a relational symbol of equivalence. This partial understanding can be the result of overemphasis on canonical equation syntaxes of the type a + b = c in elementary school mathematics. This paper presents an examination…

The illustration characteristics of 221 visual representations (VRs) of submicroscopic particles in nine Greek secondary chemistry school textbooks from the last three decades were analyzed. This analysis was done to develop a taxonomy that could help science teachers and curricula designers evaluate the efficacy of such characteristics on student…

In order to deal with the constantly and rapidly changing conditions of life, a decision-making capacity is needed. Critical thinking can help effectively in this, and that is why it is an ability that modern education seeks to cultivate. In Informatics-related education, critical thinking is essential. Consequently, in Informatics textbooks it is…

This paper studies Greek junior high school students' alternative ideas, both initial and synthetic, on geodynamic phenomena. It comments in detail on students' concepts on Earth structure, earthquake occurrence, volcano formation, and relief change. Additionally, it attempts to trace and interpret how and why these ideas form (concept…

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…

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…

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…
