    Recently, automated short-answer grading (ASAG) methods based on deep neural networks (DNN) have attained high scoring accuracy. However, the accuracy requires further improvement especially for large-scale and high-stakes tests because a slight scoring error will strongly influence many examinees. To improve the accuracy, this study proposes a new DNN-based ASAG method that utilizes examinees’ abilities which are estimated using an item response theory model from their true-false responses for objective exam questions offering with a target short-answer question.

    This paper describes a design of learning method aiming to promote learners’ acquisition of the analysis viewpoints in system requirements analysis. We provided learners with three viewpoints, “Functional defects”, “Operability” and “Users”. By doing this, we intended to promote learners to point out the problems about system such as lack of functions and ambiguity of requirements. In addition, we tried to make learners re-analyze task to aim that they acquire of relationship of abstract viewpoints and specific problems themselves. As a result of experiment, we found that the learners without work experience improved problem-pointing by being aware of viewpoints.
