'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

Teaching and learning relies on age-appropriate, credible formal (e.g., textbooks, textbook supplements) and informal (e.g., trade-books) curricular texts. Previous research traced American publishers' self-censorship about human evolution within twentieth-century textbooks. This study, informed by the latest scientific understandings, engaged in…

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…

Science texts tend to privilege the voices, perspectives, and practices of White males (e.g., Ford, 2006), reinforcing widely-held perceptions of scientists as White men. This narrow portrayal of who "does science" discourages BIPOC or female students from building a science identity (Archer et al., 2015), with many such students also…

With limited time for science, using science trade books for science and language instruction has become more common in elementary schools. Studies show that trade books often neglect scientific practices. Yet previous analyses have not differentiated by targeted grade level nor by book type. Do some grade levels and types of books highlight…

Background: Teaching and learning of nature of science (NOS) is an explicit goal in the core science curriculum in Norway. Yet there is little understanding of how the content of the current textbooks in certain educational pathways such as vocational training addresses NOS. Purpose: The aim of this study is to contribute to research on NOS in VET…

This paper investigated constraints associated with biology teaching and learning materials in selected schools in the Central Region of Ghana. The purpose of this study was to evaluate the classroom implementation of biology curriculum. A cross-sectional descriptive survey design was used for the study. The target population comprised 187 biology…

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…

In a chemistry course for students not majoring in science, there is more to learn than some memorized facts: the student can find, in most non-major chemistry texts, the definition of atomic number, something about chemical bonding, and names of some classes of chemical compounds. Where facts come from and how accurately they are known are often…

To reduce the cost of educational materials needed by students, we generated a no-cost open educational resources (OER) textbook for an undergraduate level cell biology course. Cell biology is part of the curriculum in various undergraduate degrees for science, technology, engineering, and math majors, therefore generation of OER targets a large…

Curriculum statements are crucial documents for guiding teaching and learning as they describe the content and skills to be acquired by learners. Textbooks translate curriculum statements into materials for use in schools. This study examines the educative nature of three physical sciences textbooks about electrostatics using the lens of…

The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

The science curriculum aims to provide students with the identity of a researcher, thinking skills, and scientific process skills. Critical thinking skill emerges as one of the skills that should be emphasized in the teaching process in terms of its structural features and the qualities aimed to be given to individuals. For individuals to gain…

This report includes the analysis of three chemistry textbooks in high schools in Iran for representation of nature of science (NOS). The analysis was framed by an analytical tool developed and validated by Abd-El-Khalick and a team of researchers in a large-scale study on the high school textbooks in the USA. The results indicated that NOS…
