|Abstract:||This paper examines techniques for modeling relationships among domain concepts and practices in discourse to assess learning in a CSCL environment. We compare two approaches: a traditional psychometric approach, which models the global correlation structure of student discourse markers across the learning intervention, and a model that accounts for the local correlation structure of discourse markers within activities. We investigate whether: (a) analysis of local correlation structure can identify significant differences between novices and relative experts; (b) these differences reflect meaningful differences the discourse; and (c) analysis of global correlation structure can identify significant differences between novices and relative experts. We assess whether an approach that models local relationships among concepts in a domain provides useful information beyond what might be extracted from a more traditional modeling approach. Our results indicate that techniques that account for local correlation structure can identify patterns in discourse not reflected in global correlation structure.|
