In the mathematical literature on analytical geometry, various notions of the conics' eccentricity correspond to different approaches to these curves. After making a comparative analysis of well-known textbooks to determine coincidences and differences between the various concepts of eccentricity, as well as how the authors explain the…

This qualitative research, employing content analysis, aims to achieve two objectives: (1) to examine self-values, which encompass the categories of literacy and environmental assessment, and (2) to explore social peace values, which include the categories of content and environmental literacy assessment. The research data consist of images…

This paper aims to investigate how and to what extent 'critical' global citizenship is reflected in middle school English textbooks in Korea. Framed within Freire's concept of critical literacy, the study is concerned with analyzing the written texts in two English textbooks, with a focus on the issue of representations. Using critical content…

The study in this report focuses on four historical periods and five textbooks.

Three of the 5 textbooks are intended for regular high school American…

Extracting and formally representing the knowledge embedded in textbooks, such as the concepts explained and the relations between them, can support the provision of advanced knowledge-based services for learning environments and digital libraries. In this paper, we consider a specific type of relation in textbooks referred to as…

The logistic differential equation is ubiquitous in calculus and differential equations textbooks. If the model is developed from first principles in these courses, it is usually done in an abstract mathematical way, rather than in one based in ecology. In this short note, we look at examples of how the model is derived in mathematical texts and…

The main natural risk in the Mediterranean region is flooding. Therefore, in Spain, explaining this issue in Primary Education classrooms of Social Sciences should be a priority and is established as such in the current curriculum. The aims of this study are to carry out an analysis of the contents on flood risk included in the Social Science…

The gender gap remains an issue in the biological education community. This study explores the extent to which an egalitarian gender ideology, encapsulated in five biological science textbooks for upper secondary schools in China, manifests through representational, interactive and compositional meanings of social semiotic theory. The findings…

Introduction: Textbook tasks are considered as tools for implementing, endorsing mathematical thinking and thereby creating chances for mathematics learning. Therefore, textbook tasks can potentially influence and structure the way students think and can serve to limit or to broaden their views of the subject matter with which they are engaged.…

Textbooks use images, in addition to text, for delivering knowledge, thereby convey attitudes and values of students including those on gender bias. The gender bias presented in textbook images affects in subtle ways the students' learning outcomes, career choices, and how they perceive science. However, prior research has relied on explicit…

Infinite series are known to be challenging for Calculus II students, perhaps because they lack intellectual need for the content. In their analysis of Calculus textbooks found few instances of potential intellectual needs for infinite series. This study combines a textbook analysis with interviews of four professors and observations of their…

In this study, it was aimed to examine the visual content and expressions in the texts in the "Cell Divisions" unit in the 10th Grade Biology textbook of the Ministry of National Education, Secondary Science High School, taught in the 2022-2023 academic year, in terms of scientific content. The data sources of the research, in which the…

Textbooks play a vital role in the Nepali education system since they are one of the main resources for teaching and learning mathematics. Because of poor physical infrastructure and inadequate educational resources, both teachers and students heavily rely on textbooks. In this regard, this study investigated the mathematics textbook authors'…

Much of the attention given to literacy, of late, has focused on ensuring that students can read, without consideration to what they are given to read. Kristin Conradi Smith & Elfrieda H. Hiebert discuss four general aspects of the texts used in elementary classrooms -- text complexity, text type (narrative versus informational), text format…

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…
