Direct answer直接回答
An AI lecture summarizer should turn a recording into a structured learning aid while keeping definitions, examples, caveats, and timestamps connected to the lecture. Start with a lecture recording or transcript you may process, slides or syllabus when available, and the learning objectives; the working deliverable is a reviewable outline, concept explanations, examples, questions, and timestamped source moments.
AI 课程摘要工具应把录像整理为结构化学习资料，同时保留定义、示例、限定条件以及与课程对应的时间码。 开始前应准备有权处理的课程录像或文字稿、可用幻灯片或教学大纲以及学习目标；工作结果应形成可复核提纲、概念解释、示例、问题和关联来源的时刻。

Map the lecture's teaching design before compression压缩前先识别课程教学结构
A lecture is not simply a long speech. It may introduce prerequisites, define a model, derive an equation, demonstrate a procedure, compare cases, and assign practice. Begin by mapping these teaching moves and noting which ideas depend on earlier ones. An AI lecture summarizer that selects only repeated sentences can omit the derivation that makes the final formula understandable. The summary brief should name the course level, learning objectives, assessment format, and whether the student needs orientation, revision, or remediation.
课程并不是一段很长的演讲，它可能先介绍前置知识，再定义模型、推导公式、演示流程、比较案例并布置练习。摘要前应识别这些教学动作以及概念之间的依赖关系。若 AI 只保留重复句子，可能会漏掉让最终公式可理解的推导。任务说明应写清课程层级、学习目标、考核形式，以及学生需要的是预习、复习还是补缺。
Summarize concepts, reasoning, and practice separately分别整理概念、推理与练习
Build three connected outputs. The concept sheet lists definitions, conditions, and relationships. The reasoning sheet records the sequence from question to conclusion, including assumptions and counterexamples. The practice sheet turns worked examples into prompts the learner can attempt without seeing the answer. Add timestamps to the explanation, derivation, and example rather than only to chapter openings. This structure prevents a concise overview from being mistaken for mastery and gives the learner a route back to instruction when recall fails.
可以建立三份关联结果：概念表记录定义、适用条件与关系；推理表记录从问题到结论的顺序，包括假设与反例；练习表把课堂例题改成学生在看不到答案时可以尝试的问题。时间码应指向解释、推导与例题，而不仅是章节开头。这种结构能避免把简洁概览误当成真正掌握，并在回忆失败时提供返回教学内容的路线。
Recover information that never entered the transcript补回从未进入文字稿的视觉信息
Inspect slides, whiteboards, code, diagrams, and gestures that carry decisive information. A transcript may say “move this term over here” without naming the term, or “as shown in the graph” without describing the axes. Capture those details as visual notes linked to time and label them separately from spoken text. For equations and code, compare symbols character by character with the screen or official material. Do not let fluent language hide a missing diagram or an incorrect operator.
应检查幻灯片、白板、代码、图表和手势中承载的关键信息。文字稿可能只写“把这一项移到这里”，却没有说明是哪一项；也可能写“如图所示”，却没有描述坐标轴。应把这些细节作为视觉笔记并关联时间，同时与口语文本分开标记。公式和代码要逐字符对照屏幕或官方材料，不能让流畅语言掩盖缺失图表或错误运算符。
Test whether the summary supports retrieval and transfer测试摘要能否支持回忆与迁移
After reading, ask the learner to explain one concept, reproduce one reasoning chain, solve a changed example, and identify one limitation without reopening the notes. Record which step fails and link it to the relevant lecture moment. Questions answered by simple recognition are too weak; use prompts that require generation or application. The final artifact should distinguish what the lecturer stated, what the summarizer inferred, and what the learner still cannot do. That distinction turns a summary into a study instrument.
阅读摘要后，让学习者在不打开笔记的情况下解释一个概念、复现一条推理链、解决一个变化后的例题并指出一个限制。记录失败步骤并链接到对应课程时刻。只要求识别答案的问题过弱，应使用需要主动生成或应用的提示。最终材料要区分讲师明确陈述、摘要系统推断以及学习者仍不会的内容，这样摘要才能成为学习工具。
Define the learning output before summarizing the lecture摘要课程前先定义学习输出
Specify whether the learner needs preview notes, a post-class explanation, exam revision, or remediation of a known gap. Then list the required fields: learning objectives, prerequisites, core concepts, reasoning steps, examples, formulas with assumptions, misconceptions, and questions for recall and application. Map these fields to lecture time before compressing. Preserve where the instructor changes a definition, corrects an earlier statement, or answers a student objection. A concise summary may omit anecdotes, but it should not detach an example from the concept or a formula from its conditions. After drafting, attempt the recall questions without looking and use wrong answers to identify missing prerequisites or unclear boundaries. Reopen only the linked segments to repair those gaps. The result is accepted when a learner can explain and apply the material after a delay, not when the notes merely sound complete on first reading. Keep failed practice answers because they reveal which explanations need another example or clearer prerequisite.
先明确学习者需要预习笔记、课后解释、考前复习，还是修复已知知识缺口，再列出必要字段：学习目标、前置知识、核心概念、推理步骤、案例、带假设的公式、常见误解，以及回忆与应用问题。压缩前先把这些字段映射到课程时间。讲师改变定义、修正前述观点或回应学生异议的位置必须保留。简短摘要可以省略轶事，但不能让案例脱离概念，也不能让公式脱离适用条件。草稿完成后，在不查看内容的情况下尝试回答回忆问题，用错误答案发现缺失的前置知识或模糊边界，再只重看关联片段进行修复。结果是否合格，应由学习者间隔一段时间后能否解释并应用材料来判断，而不是由笔记初读时是否显得完整来判断。保留练习中的错误答案，因为它们能指出哪些解释需要更多案例或更清楚的前置知识。
Worked example具体示例
For a statistics lecture, request definitions, worked-example steps, assumptions, and three self-test questions. Verify each formula against the slide and link confusing transitions to playback times.
整理统计课程时，可要求输出定义、例题步骤、假设与三个自测问题。每个公式都要对照幻灯片，并把难懂的过渡位置关联到播放时间。
Before handoff, preserve the source identity, current edit, language, access date, and every time reference needed to reproduce the example. A fluent study guide can still be wrong. Formulae, quotations, terminology, and instructor-specific claims require direct checking against audio and slides.
交付前应保留来源标识、当前剪辑版本、语言、访问日期，以及复现实例所需的时间信息。页面输出用于支持理解与整理，重要原话、数字、人物、边界和解释仍需返回原视频检查。
Define acceptance for this deliverable为这项交付物设定验收条件
Build study artifacts, not a polished shortcut. Review the result against the intended audience and the declared task of evaluating an AI workflow for lecture summaries and study artifacts. Confirm that the chosen structure preserves the distinctions the reader must act on, rather than simply shortening the recording. Mark missing source material and uncertainty openly. A reviewer should be able to identify which items came directly from speech or visuals, which were reorganized, and which are interpretations.
生成学习材料，而非华丽捷径。应围绕目标读者以及“评估用于课程摘要与学习材料的 AI 流程”这一具体任务验收结果。检查结构是否保留读者行动所需的关键区分，而不是只把录像缩短；来源缺失与不确定性必须显式标记。复核者应能分辨哪些内容直接来自语音或画面、哪些经过重组、哪些属于解释。
Use a small handoff record containing source, purpose, output version, correction notes, tested links or time ranges, reviewer, and unresolved items. Review every name, number, quotation, formula, instruction, commitment, and people-related conclusion that could cause harm if wrong. Lower-risk descriptive material may be sampled, but the sampling rule should be written down. A result is accepted because it is fit for this declared use, not because its language sounds confident.
交接记录至少应包含来源、用途、输出版本、修正说明、已测试链接或时间范围、复核人和未解决事项。姓名、数字、引语、公式、指令、承诺以及涉及个人且出错会造成影响的结论都应逐项检查；低风险描述可以抽样，但抽样规则要写明。结果被验收是因为适合当前用途，而不是因为语言显得自信。

Questions about this task本任务常见问题
How is a lecture summary different from a video summary?
课程摘要与普通视频摘要有什么不同？
It preserves learning objectives, prerequisites, reasoning, examples, and practice rather than only compressing topics and conclusions.
它需要保留学习目标、前置知识、推理、例题和练习，而不只是压缩主题与结论。
Should formulas be copied from the transcript?
公式可以直接从文字稿复制吗？
No. Verify formulas, symbols, and code against slides, the screen, or official course material because speech recognition is unreliable for notation.
不应直接复制。语音识别不擅长符号，应对照幻灯片、屏幕或官方课程材料核实公式、符号与代码。
What timestamps are most useful for study?
哪些时间码最适合学习？
Link definitions, derivations, worked examples, misconceptions, and recap moments that a learner may need to revisit.
应链接定义、推导、例题、常见误区和回顾等学习者可能需要重看的时刻。
How can I test a lecture summary?
如何测试课程摘要？
Try explaining, reconstructing, and applying the material without notes; use failures to locate missing context or weak prompts.
在不看笔记时尝试解释、重建并应用知识，再用失败位置查找缺失上下文或薄弱问题。
