Abstract

Cartographic maps have guided our explorations for centuries, allowing us to navigate the world. Science maps have the potential to guide our search for knowledge in the same way, helping us navigate, understand, and communicate the dynamic and changing structure of science and technology. Allowing us to visualize scientific results, science maps help us make sense of the avalanche of data generated by scientific research today. Atlas of Science, features more than thirty full-page science maps, fifty data charts, a timeline of science-mapping milestones, and 500 color images; it serves as a sumptuous visual index to the evolution of modern science and as an introduction to "the science of science"--charting the trajectory from scientific concept to published results. Atlas of Science, based on the popular exhibit "Places & Spaces: Mapping Science," describes and displays successful mapping techniques. The heart of the book is a visual feast: Claudius Ptolemy's Cosmographia World Map from 1482; a guide to a PhD thesis that resembles a subway map; "the structure of science" as revealed in a map of citation relationships in papers published in 2002; a periodic table; a history flow visualization of the Wikipedia article on abortion; a globe showing the worldwide distribution of patents; a forecast of earthquake risk; hands-on science maps for kids; and many more. Each entry includes the story behind the map and biographies of its makers. Not even the most brilliant minds can keep up with today's deluge of scientific results. Science maps show us the landscape of what we know. Exhibition Ongoing National Science Foundation, Washington, D.C.

Footnote

This book is evidence that Henderson and Tallman were meticulous in following their established protocols and especially in their record keeping while conducting their research. There are, however, a few issues in the study's framework and methodology that are worth noting. First, although the research was conducted in two different countries - the United Slates and Australia - it is not clear from the writing if the librarian-pupil pairs of each country hailed from the same schools (making the population opportunistic) or if the sampling was indeed more randomly selected. Readers do know, though, that the librarians were free to select the students they tutored from within their respective schools. Thus, there appears to he no randomness. Second, "[t]he data collection tools and questionnaires were grounded in a [single] pilot study with a [single] teacher-Iibrarian" (p. 7). Neither the procedures used nor the data collected from the pilot study are presented to establish its reliability and validity. Therefore, readers are left with only limited confidence in the study's instrumentation. Further, it is obvious from the reading, and admitted by the researchers, that the recording equipment in open view of the study's subjects skewed the data. That is, one of the librarians tinder study confessed that were it not for the cameras, she would have completely deserted one of her lessons when encountering what she perceived to be overwhelming obstacles: a classic example of the Hawthorne Effect in research. Yet. despite these issues, researchers Henderson and Tallman make a respectable ease in this book for the validity of both mental models and stimulated recall. The mental models developed during the prelesson interviews seem remarkably accurate when observing the school librarians during the lessons. Additionally, while the librarians were able to adapt their lessons based on situations, they generally did so within their mental models of what constitutes good teachers and good teaching.
