📝 摘要（中文）

随着大语言模型在教育领域的广泛应用，作为辅导员、助教和内容生成者，这些模型面临着比普通问答更高的要求。现有基准测试往往孤立评估这些需求，缺乏综合性评估。本文提出ELBench，这是第一个在统一协议下评估模型的四个关键需求（通用能力、安全性与可信度、基础教育和高层次培养）的基准。通过对九个模型的评估，发现模块级别的表现比单一总分更具信息量，且中国开发的模型在安全性模块中表现优异。教育专用模型在教育模块中未能领先，且在高层次培养任务中所有模型均表现出系统性的盲点。

🔬 方法详解

问题定义：本文旨在解决现有基准测试无法综合评估教育领域大语言模型的多维需求这一问题，现有方法往往孤立评估各个方面，缺乏整体适用性。

核心思路：ELBench基准通过统一协议评估模型的四个关键维度，结合公共数据源与新合成的安全性和培养数据，以全面了解模型的教育适用性。

技术框架：ELBench的整体架构包括四个主要模块：通用能力、安全性与可信度、基础教育和高层次培养。每个模块通过特定的评估标准和数据集进行测试。

关键创新：ELBench是首个综合评估教育领域大语言模型的基准，能够同时考虑多个维度的表现，填补了现有方法的空白。

关键设计：在设计中，采用了模块化评估方法，确保每个模块的独立性和可比性，同时在安全性评估中引入了区域特定的规范内容，以提高评估的准确性。

📊 实验亮点

实验结果表明，尽管前六个模型在总体评分上没有显著差异，但其模块表现差异显著，安全性与实际教学效果呈负相关（r = -0.83）。中国开发的模型在安全性模块中表现最佳，尤其在区域特定内容上优势明显。

🎯 应用场景

ELBench的提出为教育领域的大语言模型评估提供了新的标准，能够帮助教育工作者和研究人员更好地选择和优化模型。其潜在应用包括智能辅导系统、个性化学习平台和教育内容生成工具，未来可能对教育技术的发展产生深远影响。

📄 摘要（原文）

Large language models are increasingly deployed in education as tutors, teaching assistants, and content generators. These roles place demands that ordinary question answering does not: a usable education-facing model is supposed to be accurate, safe under sensitive prompts, instructionally useful, and aligned with pedagogical goals at the same time. Existing benchmarks evaluate these requirements largely in isolation, so none assesses education-facing suitability as an integrated profile. We introduce ELBench, the first benchmark to evaluate all four requirements (General Capability, Safety and Trustworthiness, Basic Education, and High-Level Cultivation) on the same models under a common protocol, combining curated public sources with newly synthesized safety and cultivation data. We evaluate nine models, seven frontier general-purpose systems and two education-specialized variants, and report three findings. First, module-level profiles are more informative than a single aggregate: the top six models are statistically indistinguishable on overall score, yet their module leaders differ substantially, and safety is anti-correlated with practical teaching (r = -0.83). Second, the Chinese-developed models lead the safety module, the most discriminative in the suite; this advantage is largest on region-specific normative content and narrows, but does not vanish, on universal-harm content. Third, the two education-specialized models lead neither education module, and on High-Level Cultivation all models share a systematic blind spot: on the structured judgment task they converge on the same non-reference option, favoring pedagogical style over fit to the stated goal, so the module scores uniformly low and does not separate models. This raises, but does not resolve, whether domain post-training keeps pace with frontier systems on education tasks.
