All our experiments involve parallel corpora of sentences and formal representations of scenes, and unsupervised data mining algorithms to find structure in the scenes that might be associated with occurrences of words. Recently, our Wubble World project has demonstrated that large sentence-scene corpora can be extracted from transcripts of children playing online games. The second half of the talk is about web-based educational technology, particularly intelligent tutoring systems and modeling students' engagement and learning statistically on the basis of their overt problem-solving behavior. As more students use online educational technology, there will be great opportunities for educational data mining and challenges for Education Informatics.</span></p> <div class="MsoNormal"><span style="font-size:12.0pt"> <o:p></o:p></span></div><p class="MsoNormal" align="center" style="text-align:center">Host: “Stuart A.
