AI改变学习目标,评估需重构以实现教学对齐
The Impact of AI on Educational Assessment: A Framework for Constructive Alignment
- 基于建构对齐理论,区分AI对不同认知层次的影响
- 教师使用AI程度影响评估态度,存在显著认知偏差
- 建议高校制定统一评估指南并开展AI能力培训
人工智能,特别是大语言模型(LLM),在教育中的影响持续扩大。学生频繁使用这些模型,引发当前评估方式是否仍能有效衡量学习成果的疑问。本文基于建构对齐(CA)理论和布卢姆分类学,提出学习目标在不同认知层次上受AI影响的方式各异,评估方法须相应调整。同时,根据布卢姆理念,形成性与总结性评估应明确是否允许使用AI。尽管教师普遍认同教育与评估需适应AI,但其对允许程度的认知存在显著偏差,主要源于自身对AI的熟悉度与使用情况。为减少偏见,本文建议在大学或院系层面制定结构化指导方针,促进师资共识。此外,教师需接受关于AI工具能力与局限性的系统培训,以更有效地调整评估策略。
原文摘要 · Abstract (English)
The influence of Artificial Intelligence (AI), and specifically Large Language Models (LLM), on education is continuously increasing. These models are frequently used by students, giving rise to the question whether current forms of assessment are still a valid way to evaluate student performance and comprehension. The theoretical framework developed in this paper is grounded in Constructive Alignment (CA) theory and Bloom's taxonomy for defining learning objectives. We argue that AI influences learning objectives of different Bloom levels in a different way, and assessment has to be adopted accordingly. Furthermore, in line with Bloom's vision, formative and summative assessment should be aligned on whether the use of AI is permitted or not. Although lecturers tend to agree that education and assessment need to be adapted to the presence of AI, a strong bias exists on the extent to which lecturers want to allow for AI in assessment. This bias is caused by a lecturer's familiarity with AI and specifically whether they use it themselves. To avoid this bias, we propose structured guidelines on a university or faculty level, to foster alignment among the staff. Besides that, we argue that teaching staff should be trained on the capabilities and limitations of AI tools. In this way, they are better able to adapt their assessment methods.
