    摘要: The work aims to improve the assessment of creative problem-solving in science education by employing language tech- nologies and computational-statistical machine learning methods to grade students` natural language responses automat- ically. To evaluate constructs like creative problem-solving with validity, open-ended questions that elicit students` constructed responses are beneficial. But the high cost required in manually grading constructed responses could become an obstacle in applying open-ended questions. In this study, automated grading schemes have been developed and evalu- ated in the context of secondary Earth science education. Empirical evaluations revealed that the automated grading schemes may reliably identify domain concepts embedded in students` natural language responses with satisfactory inter-coder agreement against human coding in two sub-tasks of the test (Cohen`s Kappa = .65-.72). And when a single holistic score was computed for each student, machine-generated scores achieved high inter-rater reliability against human grading (Pearson`s r = .92). The reliable performance in automatic concept identification and numeric grading demon- strates the potential of using automated grading to support the use of open-ended questions in science assessments and enable new technologies for science learning.
