This essay examines how line graphs functioned as markers of status and authority in early 20th-century America, distinguishing intellectual elites from ordinary citizens. Despite education reformers' efforts to democratize functional thinking and graphical representation in the first decades of the century, line graphs retained their position as…

The teacher's use of representations is a crucial aspect of instructional quality in mathematics education, given their pivotal role in facilitating mathematics learning. However, in our international research community, perspectives on what constitutes high-quality use of representations may vary. This cross-cultural study aims to explore whether…

We use eye tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results of this study show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of…

In the social studies of science, visuals and graphical representations are theorized by means of the concept of inscription, a term that denotes all representations other than text inscribed in some medium including graphs, tables, photographs, and equations. Inscriptions constitute an intrinsic and integral part of scientific practice; their…

We start from the assumption that school mathematics knowledge could be better explained if social practices were considered to be generators of knowledge. This perspective changes the way we look at what school mathematics knowledge is and what it takes to teach and learn it. In this article, we will present a teaching situation about periodic…

Compares the "New York Times" and the "Asahi Shimbun" in terms of density, variety, and extensive use of statistical and didactic graphics. Concludes that cultural factors account for the style of newspaper graphics, social factors for their acceptability, and organizational factors for their type and density. (JMF)

Introduces a collection of mathematics activities that use Spain and Spanish culture as the setting for activities that involve graphing, estimation, logical reasoning, geometry, measurement, and computation. These activities are designed to appeal directly to students. (KHR)

Papers include: (1) "What Do We Believe about Teacher Learning and How Can We Learn With and From Our Beliefs?" (Deborah Loewenberg Ball); (2) "Toward Evidence for…

Examines Ocracoke English (OE), a dialect of American English spoken on Ocracoke Island, located off the coast of North Carolina. The article presents linguistic and sociolinguistic evidence that OE is an endangered dialect and describes the development of a community-based preservation program paralleling proactive programs implemented for…
