This systematic review summarized 42 selected empirical studies on the representations of nature of science (NOS) in science textbooks guided by three theoretical frameworks, which are the four-theme scientific literacy (SL), the consensus view on nature of science (CV), and the family resemblance approach to the nature of science (FRA). This…

As a result of human beings' activities to dominate nature and transform it for their own benefit as they continue to advance in science and technology, environmental problems such as climate change have become the biggest threat faced by the biosphere in the current century. One of the biggest problems of humanity today is the scarcity of water…

This communication shows that although some textbooks do not discuss how to apply Raoult's law to electrolyte solutions, we should not ignore dissociation, and the van't Hoff factor must be considered.

In this study, we analyzed how scientific terms such as principle, law and theory are depicted in Chemistry textbooks used by students in Singapore. There are very few reports in the science or chemistry education literature that explicitly explore the term principle, although all three terms appear in a number of topics in the high school…

Studies on the quality of nature of science (NOS) representations in school science textbooks report them being mostly of implicit manner and not fully adequate. However, the often underlying NOS framework of the consensus list in these studies is criticized as undifferentiated and inadequate. The family resemblance approach (FRA) to NOS shows…

The weight, one of the key concepts of physics education, still continues to be discussed among physics educators. Today, there are two main definitions as the 'gravitational' and 'operational', but there are differences even between them. It is important to know the different approaches found in textbooks in eliminating misconceptions and…

Visual representations (and their censorship) are carriers of messages and are powerful tools to invoke discourses. Visuals are not just supplements to written text; rather, these can be read independently as the primary text and are crucial to scientific communication, particularly in life sciences. This paper aims to investigate various textbook…

There is currently a lack of systematic study examining the integration of verbal-visual elements in science textbooks. In particular, few research has investigated how different types of visual representations (e.g. photograph, diagram, table) vary across the major written genres of science (e.g. information report, explanation). Based on the…

Scholars as exemplars and their linked eponyms play a significant role in education. Since the discovery of the periodic law in 1869, perceptions of Mendeleev and his eponyms may have shifted. With the aim of assessing the historical and current portrayal of Mendeleev and his eponyms in chemistry textbooks and on the Internet, content analysis of…

Intellectual demands of learning outcomes in the intended curriculum have always been a concern across the field of science education. In particular, the representation of those learning outcomes stipulated by the intended curriculum in science textbooks has become a big issue for both science curriculum studies and science teaching practice. To…

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…

Concepts are the essential elements of basic sciences. For meaningful learning, these concepts need to be expressed clearly and accurately. Before the teaching methods and techniques are used, the concepts' definitions, limitations, and exceptions should be explained. Therefore, the purpose of this research was to determine whether the definition…

Visual elements such as graphs, tables, and diagrams are essential components of scientific writing. Although scientific writing textbooks and guides often contain information on how to design such visuals, little has been written on how to effectively discuss those visuals within the text. This article offers a novel heuristic for teaching…

In this paper, we explore how science textbook authors reconciled their personal hopes with disciplinary and societal demands in their writing. Using a qualitative narrative storytelling research method, we interviewed four Canadian science textbook authors about their hopes and the challenges they encountered in their writing. To understand their…

The diversity of scientific methods has received widespread recognition in recent years. The purpose of this review is to analyze the changes in the representation of laboratory work in Chinese senior high school chemistry textbooks in the past 30 years from the perspective of the diversity of scientific methods. This study was based on Brandon's…
