摘要

本文提出了一种自动评估代数问题多步答案的系统。该系统只要求教师在出题阶段参与。目前支持两种类型的代数问题:包含分数的线性方程问题和二次方程问题。系统会评估学生答题的每一步，并根据评分方案给予满分/分数线。该系统的性能评估使用了一套来自斯里兰卡一所政府学校的学生答题脚本以及本科生的答题脚本。对于上述数据集，系统的准确率分别超过95.4%和97.5%。

Computer Aided Evaluation of Multi-Step Answers to Algebra Questions

This paper presents a system that automatically assesses multi-step answers to algebra questions. The system requires teacher involvement only during the question set-up stage. Two types of algebra questions are currently supported: questions with linear equations containing fractions, and questions with quadratic equations. The system evaluates each step of a student's answer and awards full/partial marks according to a marking scheme. The system was evaluated for its performance using a set of student answer scripts from a government school in Sri Lanka and also by undergraduate students. The system accuracy was over 95.4%, and over 97.5%, respectively for the aforementioned data sets.
