The Decapoda - shrimp, lobsters, and crabs - are an economically important, diverse group of animals whose geologic history extends back 400 million years. Living representatives, numbering over 15,000 species, are global in distribution and nearly ubiquitous in oceanic and non-oceanic environments. They exert a major impact on ecosystems; understanding the dynamics of their fossil record will illuminate their historical impact on ecosystems. We will test the hypothesis that decapods are arrayed in a series of discrete evolutionary faunas; remarkably, the vast array of living and fossil decapods in diverse interrelated groups have exploited four basic body plans repeatedly. Other hypotheses to be tested are that the Decapoda have repeatedly adopted a limited number of baupläne, or generalized architectures, throughout their history; that they have experienced explosive evolutionary radiations followed by periods of no determinable change; and that they are generally resistant to mass extinction events. These hypotheses will be tested using a unique dataset compiled and assessed by the Principle Investigators: a compilation of all fossil decapod species, arrayed in a classification scheme including fossil and living taxa, with geologic and geographic ranges of all species, including a phylogeny (i.e. "family tree") for many sub-groups within the Decapoda. The dataset will be expanded to include ecological data for each taxon and will be entered into the Paleobiology Database, an NSF-supported vehicle for analyzing the fossil record. Employing its methodology, patterns of diversity and macroevolution of the decapods will be generated at levels ranging from the entire Order to species level. This will result in a comprehensive analysis of macroevolutionary patterns of this major group for the first time. Available paleoecological data derived from field studies and published records will be used to determine the effects of various environmental factors such as seafloor conditions, reef development, water depth, and temperature on morphology, extinction survivorship, and diversity. Because decapods have a remarkable range of morphological variation preservable in the fossil record, the diversity of the groups of decapods can be assessed in relation to their morphological characteristics. Defining the history of taxa with specialized morphology will permit recognition of body plans that have been exploited by different decapod groups throughout the history of the clade.
Intellectual merit. This study will provide the most comprehensive analysis of macroevolution of the Decapoda yet conducted, all based upon a unique dataset that is internally consistent by virtue of its having been developed entirely by the investigators. It will document the significance of employing a high resolution, species-level database for interpretation of diversity. The hypotheses and conclusions derived here will provide a model and the foundation for future work on Decapoda, Arthropoda, and macroevolution of well-constrained groups. It will provide a test for the efficacy of PBDB data versus a constrained dataset assessed by specialist systematists.
Broader impacts. The work will introduce undergraduate students at Kent State at Stark, an undergraduate campus, and Kent State at Kent, to research that involves paleoecological, paleogeographical, and functional morphological elements which, in turn, will be communicated to other students. Because decapods are known to virtually everyone, they form an excellent group to use to inform the public about ancient patterns of diversity and the relationship between the morphology of organisms, variations in their environmental requirements, and their adaptability to different physical conditions. This will be conveyed in a professionally constructed display which has the potential to be exhibited in museums and universities around the country. Small kits designed for use in elementary and middle schools will be available to allow students to make their own observations about the adaptations of decapods to their environment and its effect on diversity. Published papers and presentations on results of research at meetings will be prepared throughout the course of the research. Because the study of modern biodiversity is a concern of the general public, presentations to broader audiences as well as geology classes will provide a broad historical context for understanding modern patterns of diversity. Data entered into Paleobiology Database and Ohio Data Resource Commons will be openly available to other researchers and the general public. Combined, the databases will assure archival storage and public access, following a proprietary period.
Discovering and understanding the temporal evolution of events hidden in text corpora is a complex yet critical task for knowledge discovery. Although mining event dynamics has been an important research topic leading to many successful algorithms, researchers, research and development managers, intelligence analysts and the general public are still in dire need of effective tools to explore the evolutionary trends and patterns. This exploratory project focuses on developing and validating a novel idea called narrative animation. Narrative animation uses animated visualizations to narrate, explore, and share event dynamics conveyed in temporally evolving text collections. Film art techniques are employed to leverage the animated visualizations in information organization and change detection, with the goals of enhancing analytical power and user engagement. A prototype system called CityStories is being developed to generate narrative animations of events in cities derived from web-based text. If this novel, risky research is successful, it is expected to yield fundamental results in narrative animation that can advance the current paradigm in information visualization and visual analytics by developing novel techniques in using animations for presenting and analyzing dynamic abstract data at a large scale. The pilot system CityStories system is expected provide a novel network platform for education, entertainment, and data analytics. It will engage general users such as students, teachers, journalists, bloggers, and many others in web information visualization and study. Results of this research will be disseminated through publications, the World Wide Web, and collaborations with researchers and analysts. The project web site (http://coitweb.uncc.edu/~jyang13/narrativeanimation/narrativeanimation.htm) will include research outcomes, publications, developed software, videos, and datasets for wide dissemination to public.
The purpose of this paper is to examine the role of laboratory-based science from a perspective that synthesizes developments in (1) science studies, e.g., history, philosophy and sociology of science and (2) the learning sciences, e.g., cognitive science, philosophy of mind, educational psychology, social psychology, computer sciences, linguistics, and (3) educational research focusing on the design of learning environments that promote dynamic assessments. Taken together these three domains have reshaped our thinking about the role inquiry, and in turn the laboratory, has in science
To begin, this paper describes the climate in science education in the United States, and describes and defines formative assessment. Next, Black & Wiliam’s review and two other important empirical studies will be summarized. Then, a framework characterizing different forms of formative assessment is presented. Non-empirical studies are organized according to this continuum. Finally, the paper describes limitations in the implementation of formative assessment in K-8 science, and summarizes assessment practices that show promise for improving student learning. The important contribution of the
The media are the most pervasive disseminators of informal science education in this country. Watching commercial and non-commercial television will provide you with information on alligators or zygotes, bio-fuels or stem cells, polar bears or hurricanes. Radio, too, provides discussions of genetics and global warming and birds and stars. Often radio and television will cover science issues with a contextual overlay of politics or morality, so viewers and listeners can sense how they and their community relate to it. But for excitement, going to the theater to see an IMAX movie will take you
Technological literacy is essential to ensure lifelong engagement in rapidly changing societies. Three factors that affect learning in later adulthood are age-related declines in processing new information, changes in motivation and reprioritization of emotional wellbeing over new learning, and the ways in which beliefs and stereotypes influence motivation and learning.

This paper lays out a theory of (re-)generative learning to explain how families and communities socialize young learners into thinking like scientists and mathematicians. Cultural communities and their families orient their young in varied ways toward the language, behaviors, and self-theories about the future presupposed in the learning of science and mathematics. Certain socialization processes and norms correspond closely with those that scientists and artists use in laboratories, studios, and rehearsals. Certain norms of politeness and patterns of language differ significantly from habits
What makes “making”—the next generation of inventing and do-it-yourself—worth paying attention to? In this report, we explore the three categories of makers, the ecosystem growing around those categories, the role technology plays in this ecosystem, and, finally, how business can take advantage of the opportunities this movement represents.

This poster session showcases ten examples of expertise development in everyday domains of personal relevance and consequence to learners. The collection of cases highlighted in the posters stem from ethnographic research studies investigating learning from socio-cultural-historical perspectives. In each poster, authors describe their ethnographic project, explicate a case of expertise development, and detail the specific learning processes, practices, and pathways associated with that expertise development. Implications for understanding personally relevant and consequential learning for the
The Nature Research Center is a project through which the North Carolina Museum of Natural Sciences provides NASA with a permanent presence through the creation of NASA-themed exhibits in its new wing (the Nature Research Center), hosting special events, educator workshops and special programming, all of which serve the general population and seek to improve understanding of and engagement with science. The lead institution is the North Carolina Museum of Natural Sciences. Goals, expected and actual outcomes are as follows: Exhibits in the new wing were expected to reach 200,000 individuals in its inaugural year; in only 8 months, the Museum has welcomed over 1 million visitors. Astronomy Days’ goal was to reach 20,000 people per year and is on target for meeting this goal. Educator Workshops’ goal was to reach 32 educators per workshop and is on target for meeting this goal. The Museum’s visitor base has demonstrated an insatiable desire for NASA-themed programs. Attendance at Astronomy Days remains impressive and special space events (such as the transit of Venus, or live downlinks with the International Space Station) attract larger-than-expected audiences. The Museum appreciates NASA’s support and is eager to continue providing NASA with an ongoing presence in Raleigh, NC.
