I am an undergraduate researcher and I have used text analysis software to compare the content of student responses to two different constructed response question stems on photosynthesis.  Students were not interpreting the first question to require a process in their answer, so I changed the stem to additionally ask for the process involved.  I analyzed the responses using IBM SPSS Text Analytics for Surveys software, as well as human scoring with an analytic rubric for concepts and misconceptions.  My plans for the future are to develop machine learning scoring models for the photosynthesis question and other metabolism questions using an open-source program called SIDE (Summarization Integrated Development Environment).
