Computer-marked short-answer questions, with tailored feedback, have been in regular use in the Open University Science Faculty for 5 years. High marking accuracy has been retained following a move to algorithmically-based answer matching. However, short-answer free-text e-assessment remains an underused technology. This paper suggests some reasons for this, in particular the need for a substantial number of marked student responses for use in developing the answer matching.
