Teaching and learning are grounded on age-appropriate, credible curricular resources, which can be formal (i.e. textbooks) and informal (i.e. trade-books). As Charles Darwin's ideas galvanized biology and racism, this study examined his historical representation within trade-books (e.g. biography, narrative non-fiction, expository, etc.),…

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…

Curriculum statements and textbooks are considered to be vital support tools for teachers, particularly during times of curriculum innovation. A recent change in South Africa was the controversial inclusion of evolution in the school curriculum, raising serious concerns amongst biology teachers regarding the adequacy of their content and…

Evolution by natural selection provides the conceptual framework upon which much of modern biology is based: therefore understanding core ideas about biological evolution is an essential part of scientific literacy. Nonetheless, research repeatedly shows that high school and college students have difficulties understanding the notion of natural…

"Biological identity" is the result of interactions between the environment and the genome. These interactions, however, were not taught before 2001. In the French syllabus for 16-year-old students, two of the five sections on genetics deal with biological identity. We analysed the texts and images of the chapters relating to these two…
