In my research on recognizing children's understanding of scienceconcepts, I led the development of an annotated corpus of elementarystudent's responses to assessment questions.
We acquired grade 3-6 responses to 287 questions from the AssessingScience Knowledge (ASK) project (Lawrence Hall of Science, 2006). Theresponses, which range in length from moderately short verb phrases to severalsentences, cover sixteen diverse teaching and learning modules, spanning lifescience, physical science, earth and space science, scientific reasoning, andtechnology. We generated a corpus by transcribing a random sample(approximately 15400) of the students's; handwritten responses.
The ASK assessments included a reference answer for each of theirconstructed response questions. We decomposed these reference answers intofine-grained facets and annotated each facet according to thestudent's apparent understanding of that facet. Please see my Publications page for more detail regarding the corpus, in particular see:
