Evidence Construction in a Field Geology Environment

 Abstract: Evidence is key to many scientific practices including argumentation, explanation, and modeling. For learners engaged in scientific practices, often we aim for them to construct scientific evidence from observations in the world, but the details of how learners go from observation to verbal accounts of evidence in support of a claim in a complicated environment has been overlooked.  In this talk we argue that much can be learned about scientific practices from examining how evidence is constructed from human sensory data. We present a case of one teacher who was involved in an evidence construction activity as part of a professional development workshop in a field geology environment. Using theoretical machinery from coordination class theory we model the evidence construction process, specifically how observations as connected with prior knowledge turn into evidence for a claim.  Use this model we illuminate the teacher constructing evidence to support a claim for the relative ages of two types of rocks in the field, and we also use the model to illustrate her constructing hypothetical evidence to support an alternative claim. This case illustrates the importance of a commonly overlooked dimension of scientific practices, and implications suggest that  evidence construction is applicable to both instruction and professional development.
