To explain experiences of riders of rotating systems, such as a merry-go-round, some physics educators have employed the concept of 'centrifugal force.' However, others have suggested that the term is unnecessary in explaining experiences in rotating systems and that it encourages misconceptions surrounding circular motion dynamics. Owing to this…

The purpose of this study was to explore instructional designs for promoting inquiry practices in secondary school textbooks. Three criteria were employed to select the textbooks: (1) approved by the Ministry of Education in Singapore and the Ministry of Education and Culture in Indonesia, (2) used in secondary schools, and (3) included content…

It is agreed that algebra has an important role in physics, particularly through handling symbols. A lot of previous research has focused on how mathematics is used in physics from perspectives where mathematics is taken for granted, and not addressing potential differences of mathematics in the physics classroom and in the mathematics classroom.…

This study provides insights into the use of metaphors in protein synthesis descriptions in upper secondary chemistry and biology textbooks. Data were collected from seven Swedish textbooks and analyzed with the Metaphor Identification Protocol and categorized within the framework of Conceptual Metaphor Theory. The results reveal two main parallel…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

Biology teachers hope to teach their students more than, say, the steps of aerobic respiration. They want to help students see the living world around them in new and deeper ways. Unfortunately, the living world students encounter every day--in schoolyards and forest preserves, pets and potted plants, soil fungus and sourdough bread--is too rarely…

This study analyzed the comprehension strategies and visuals in two science textbook series for grades 6, 7, and 8 as means of better understanding a core element of the ecological component of science literacy. The iScience (Biggs, 2015"abc") and Interactive Science (Buckey, 2015abcdef) textbook series were analyzed for the frequency of…

This study analyzed the comprehension strategies and visuals in two science textbook series for grades 6, 7, and 8 as means of better understanding a core element of the ecological component of science literacy. The iScience [Biggs et al. in iScience (Grade 6), McGraw-Hill, 2015a, iScience (Grade 7), McGraw-Hill, 2015b, iScience (Grade 7),…

This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

Background: STEM education, which features interdisplines and integration of disciplines, influences the reform of curriculum and teaching, and is reflected in Chinese science textbooks. Purpose: This study aims to analyse how STEM and its integration factors are presented in Chinese science textbooks. Sample: Three sets of high school science…

Climate change has the potential to push humans across the limits at which we can exist. Chemistry is essential in understanding the complexities of climate change, as many of the processes involve chemical relationships. Textbooks influence the development of course curricula and support instructors' decision making, which can impact student…

The history of science has a unique value to teaching, and textbooks play an important role in permeating the history of science in science courses. This study aims to compare the presentation of history of science in two versions of high school physics textbooks in China. We selected the 2019 edition of the national and local textbooks as…

Cisheteronormative ideologies are infused into every aspect of society, including undergraduate science. We set out to identify the extent to which students can identify cisheteronormative language in biology textbooks by posing several hypothetical textbook questions and asking students to modify them to make the language more accurate (defined…

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…

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…
