为了验证人工智能技术在贯彻落实中央出台的多个关于中小学生学业评价改革和减负增效的政策文件中的作用，文章首先分析了宏观政策在常规学校和班级环境下贯彻实施面临的困境，指出智能评测和教学系统有助于解决现存的实施难题；然后基于在线学习系统的大规模学生学习数据，开发了一个数学智能评测和辅导系统MIATS，在对学生个性化评测的基础上，能对学生进行引导型的个性化辅导。通过在一所中学的准实验研究验证该系统对学生数学学习的促进作用；对所收集的实验数据的分析证明了该系统对减轻作业负担、增强学习效果起到非常显著的促进作用，是实现增值评价、测学结合、以测促学的有效手段。文章为智能评测和辅导系统助力落实学业评价改革和减负增效等宏观政策提供了参考和借鉴。
【英文摘要】：
In order to verify the role of artificial intelligence technology in the implementation of several policy documents issued by the central government on academic assessment reform and alleviating burdens for efficiency of primary and secondary school students, this paper first analyzes the difficulties in implementing macro policies in conventional school and classroom settings, and points out that intelligent assessment and tutoring systems can help solve the existing implementation challenges. Then, based on the large-scale student learning data from an online learning system, a mathematics intelligent assessment and tutoring system, MIATS, is developed that enables guided personalized tutoring for students based on individualized assessment of students. A quasi-experimental study in a middle school was conducted to verify the effect of the system on students' mathematics learning. The analysis of the collected experimental data proves that the system plays a very significant role in reducing the homework burden and enhancing the learning effect, and is an effective means to realize value-added assessment, combining assessment with learning and promoting learning by assessment. This paper provides a reference for the intelligent evaluation and tutoring system to help implement macro policies such as academic assessment reform and alleviating burdens for efficiency.
