Adaptations and Continuities in the Use and Design of Visual Representations in US Middle School Science Textbooks

Abstract

Visual representations are ubiquitous in modern-day science textbooks and, have in recent years, become an object of criticism and scrutiny. This article examines the extent to which changes in representations in textbooks published in the United States over the past six decades have invited those critiques. Drawing from a correlational analysis of a corpus of 34 US middle school physical science textbooks, continuities are established with respect the purposes that most textbook images serve and the numbers of schematic representations that are used. Changes are observed in the overall total number of representations in textbooks and in the proportion of representations that are photographic. Individual, interpretive cases of representations over time are presented to further illustrate the continuities and changes that have taken place. Specifically, high-fidelity images, such as photographs, are shown permeating or replacing schematic and explanatory images in the interest of promoting familiarization to students. This shifting emphasis toward familiarization is discussed as a specific cause for concern about quality and utility of representations in modern-day US science textbooks.

Gender Differences in Eye Movements in Solving Text-and-Diagram Science Problems

“…These information sources help readers to comprehend the science concepts (Cook, 2006;Hung, 2014;Lee, 2010;Yore & Tippett, 2014). The availability of information communication technologies has increased the amount and diversity of science texts and the visual components (e.g.…”

“…En los últimos años, según Lee (2010), ha habido un incremento del número de imágenes por página en los libros de texto, el doble que hace cincuenta años. Este incremento no se ha hecho a expensas del texto ya que este se mantiene.…”

Students’ Digital Photography Behaviors during a Multiday Environmental Science Field Trip and Their Recollections of Photographed Science Content

“…While there has been some precedent for considering photographs in science and environmental educational research, the research emphasis has largely been on photographic images that are produced and presented to students through instructional materials (e.g., [25][26][27]). These treatments consider photographs as a tool of instruction, and they are largely concerned with how photographs are used by educators to represent a field of study.…”
