The Need for Discipline-Based Education Research in Archaeology

Over the last few decades, scholars have recognized the importance of discipline-based education research (DBER). As outlined by the National Research Council of the National Academies, DBER aims to 1) understand how students learn discipline concepts, practices, and ways of thinking; 2) understand how students develop expertise; 3) identify and measure learning objectives and forms of instruction that advance students towards those objectives; 4) contribute knowledge that can transform instruction; and 5) identify approaches to make education broad and inclusive. Physicists, chemists, engineers, biologists, astronomers, and geoscientists have been among the first to adopt DBER. Given research that demonstrates the effectiveness of instructional strategies developed through DBER, I call for archaeologists to adopt this approach to archaeological education, while developing infrastructure that supports and advances such research and derived instruction practices

Lessons Learned from Educational Research of a National Science Foundation Research Experiences for Undergraduates

Participation in an archaeological field school is the entry point to a professional career in the discipline. Despite the importance of field schools, few scholars have investigated achieved student-learning outcomes or lasting impacts on students from participation in archaeological field research. We report on the educational design, learning objectives, and results of three years of formative and summative assessments for an interdisciplinary, archaeology and ecology research program for undergraduate students. Our learning objectives include promoting scientific literacy and communication, critical thinking and STEM skills, and capacities in archaeological and ecological interdisciplinarity. Using developed rubrics that account for both critical thinking and STEM understanding, self-administered competency surveys, and program-developed items, we found significant gains in nearly all learning objectives. Students demonstrated growth in program specific content, perceived abilities in their scientific and discipline specific skills, critical thinking skills, and scientific communication skills. These educational outcomes and assessment tools have implications for how we design and evaluate field learning in archaeology and may be applied to field school instruction

A Multi-Proxy Assessment of the Impact of Environmental Instability on Late Holocene (4500-3800 BP) Native American Villages of the Georgia Coast

Circular shell rings along the South Atlantic Coast of North America are the remnants of some of the earliest villages that emerged during the Late Archaic (5000-3000 BP). Many of these villages, however, were abandoned during the Terminal Late Archaic (ca 3800-3000 BP). We combine Bayesian chronological modeling with mollusk shell geochemistry and oyster paleobiology to understand the nature and timing of environmental change associated with the emergence and abandonment of circular shell ring villages on Sapelo Island, Georgia. Our Bayesian models indicate that Native Americans occupied the three Sapelo shell rings at varying times with some generational overlap. By the end of the complex\u27s occupation, only Ring III was occupied before abandonment ca. 3845 BP. Ring III also consists of statistically smaller oysters harvested from less saline estuaries compared to earlier occupations. Integrating shell biochemical and paleobiological data with recent tree ring analyses shows a clear pattern of environmental fluctuations throughout the period in which the rings were occupied. We argue that as the environment became unstable around 4300 BP, aggregation at villages provided a way to effectively manage fisheries that are highly sensitive to environmental change. However, with the eventual collapse of oyster fisheries and subsequent rebound in environmental conditions ca. post-3800 BP, people dispersed from shell rings, and shifted to non-marine subsistence economies and other types of settlements. This study provides the most comprehensive evidence for correlations between large-scale environmental change and societal transformations on the Georgia coast during the Late Archaic period

Seasonality and human mobility along the Georgia Bight : proceedings of the Fifth Caldwell Conference, St. Catherines Island, Georgia, May 14-16, 2010. (Anthropological papers of the American Museum of Natural History, no. 97)

236 p. : ill. (some col.), maps ; 26 cm.Conference sponsored by the American Museum of Natural History and the St. Catherines Island Foundation.Some of the most enduring and fundamental questions in archaeology relate to site seasonality. During which seasons did people occupy coastal archaeological sites? Why is "seasonality" important to our understanding of human behavior? What does this knowledge tell us about life in dynamic estuarine systems? What methods and technologies are available to address key issues of seasonality? Archaeological seasonality is uniquely linked to settlement patterns, resource availability, environmental relationships, anthropogenesis, landscapes, and social complexity. Archaeologists working in coastal settings typically recover multiple biological proxies that are well suited to explicating questions of human seasonal behavior. The Fifth Caldwell Conference was convened to discuss and report on practiced methods for reading the seasonality record found in common biological proxies. These researchers spoke of how they are applying various methods grounded in the natural sciences to estimate seasonality with particular reference to the archaeology of St. Catherines Island and the Georgia Bight. These methods include stable isotope analysis, ¹⁴C dating, longitudinal studies of animals (molluscs and fishes), zooarchaeology, and archaeobotany. The research shows that all plant and animal remains found in a midden contain a record of human behavior. The authors of these 13 chapters agree that multiple indicators of site seasonality provide the most robust picture of the annual settlement cycle. These papers were initially presented at the Fifth Caldwell Conference, cosponsored by the American Museum of Natural History and the St. Catherines Island Foundation, held on St. Catherines Island, Georgia, May 14-16, 2010.
