Most research on school-based learning has focused on learning that occurs in a classroom, laboratory, library or computer room. But in earth science, ecology, and environmental science, a different venue is important: field-based learning. In these disciplines, working "in the field" means going outside and making observations and taking samples of objects, structures, processes and phenomena, using the human senses and instrumental sensors. The features of interest include rock formations, soil, weather, plants, animals, landforms, bodies of water, the interrelations among these, and the processes by which they change through time or vary across space, either naturally or due to anthropogenic influences.
Since at least 1911 (Anonymous, 1985), field courses, field camps, field trips, field labs and field investigations have been part of the foundation for careers in geology, ecology, environmental sciences, and archeology (Kirchner, 1997; Manduca & Carpenter, 2006). Scientists in these disciplines claim that field experiences help students develop a feel for Earth processes, a sense of scale, an eye for significant features, an ability to integrate fragmentary information of different types from different localities (Turner, 2000), to reason spatially (Orion, Ben-Chaim & Kali, 1997), to visualize changes through time in geological structures (Dodick & Orion, 2003), and to analyze the quality and certainty of observational data supporting geoscience theories (Manduca, Mogk & Stillings, 2004).
Learning in the field differs along multiple dimensions from learning inside a school building (Kastens & Liben, in prep.). The scale of the study is typically large relative to the student, on the scale of meters to kilometers, as contrasted with the micron- to meter-scale objects studied in the laboratory. Thus the features under study are perceived from an internal spatial viewpoint (Bryant, Tversky & Franklin, 1992) rather than the external spatial viewpoint from which one views small objects. In a school laboratory, most objects on the lab table are relevant to the inquiry at hand, whereas for a field-based inquiry most objects in view are not relevant, and it is not obvious to the novice which are relevant and which are not (C. Goodwin, 1994; Reynolds et al., 2006). Rather than controlled experiments, field-based science often relies on methodical observation of existing variability between field sites or along gradients where hypothesized forcing factors are thought or known to vary. Field-based inquiry brings students into direct experiential contact with the raw materials of Nature. In contrast, most school-based learning begins with more distilled products, such as words, maps, diagrams, graphs, or equations, and thus the student does not experience the full cascade of inscriptions (Roth, 1996; LaTour, 1986) from the most local, concrete and material to the more abstract and mathematicized.
On the topic of learning in the field, we wish to know:
- What cognitive strategies are used in the field by master geoscientists to inform their decision-making, for example, what traverse to follow, what samples to collect, where to draw the border between map units (Broderic et al., 2004)? Amid the visual complexity of nature, how do they pick out the signs, patterns, contrasts, and aberrancies that have causal significance (Frodeman, 1996)? By what processes of observation, integration, and interpretation is new knowledge constructed in field science (e.g. Ernst, 2006)?
- How do students develop these skills? How does immersion in a field setting and the kinesthetic experience of field work affect student learning? How can geoscientists' cognitive strategies be translated into effective instructional practices, such that students can learn science by doing science in the field?
- How do students' prior life experiences influence field-based learning? What kinds of field-based learning are most effective for urban students with limited experience in Nature? Can essential aspects of field-based learning be made accessible to students with limited mobility?
- How can we assess the impacts of field experiences on student learning (e.g. concepts, content, skills), and attitudes about science?
Another promising research approach is cognitive anthropology. Through painstaking analysis of the words, gestures, and artifacts of professionals and students in an archaeological field school, Goodwin (1994, 2003) documented the intricate interactions through which a student learns to divide the complex visual field into features of importance in the profession of archeology, and then to "see" those features as embedded within a complex layering of space and time. A broad arsenal of communicative tools, including use of coding schemes, highlighting, articulation of graphic representations (Goodwin, 1994), postural orientation, tracing, inscription and collaborative pointing (Goodwin, 2003) are brought to bear on the challenge of helping the novice develop "professional vision."Browse our Growing Resource Collection Addressing Field-Based Learning
