《Sequences》读者视角问题清单

检查时间：2026-06-04

检查范围：content/courses/en/sequences 下的课程入口、章节索引和主要 MDX 课文。以下问题从读者学习体验出发整理，优先级越高，越可能直接导致读者中断阅读、误解知识或不信任课程。

P0：会直接阻断学习的问题

31 个正文页接近空骨架，读者点进去没有可学习内容

受影响文件：

• content/courses/en/sequences/applications/compound-interest.mdx
• content/courses/en/sequences/applications/geometric-problems.mdx
• content/courses/en/sequences/applications/loan-repayment.mdx
• content/courses/en/sequences/applications/population-growth.mdx
• content/courses/en/sequences/arithmetic-sequence/definition.mdx
• content/courses/en/sequences/arithmetic-sequence/general-term.mdx
• content/courses/en/sequences/arithmetic-sequence/properties.mdx
• content/courses/en/sequences/arithmetic-sequence/sum-formula.mdx
• content/courses/en/sequences/exercises/advanced-exercises.mdx
• content/courses/en/sequences/exercises/basic-exercises.mdx
• content/courses/en/sequences/exercises/intermediate-exercises.mdx
• content/courses/en/sequences/geometric-sequence/definition.mdx
• 另有 19 个同类文件未列出。

这些页面基本只剩 frontmatter、标题、组件或极少量说明，无法承接课程路径。读者会以为内容未完成，尤其当它们出现在章节中部时，会直接中断学习。

建议：补齐正文、例题、阶段小结和必要图示；若短期无法补齐，先从导航中隐藏或标注为未完成。

P1：结构和学习路径问题

7 个章节索引页缺少导读

受影响文件：

• content/courses/en/sequences/applications/index.mdx
• content/courses/en/sequences/arithmetic-sequence/index.mdx
• content/courses/en/sequences/exercises/index.mdx
• content/courses/en/sequences/mathematical-induction/index.mdx
• content/courses/en/sequences/recurrence-relation/index.mdx
• content/courses/en/sequences/sequence-limit/index.mdx
• content/courses/en/sequences/sequence-sum/index.mdx

这些索引页通常只有标题或封面组件，没有说明本章要解决什么问题、子章节顺序、前置知识或读完后的能力目标。读者进入章节入口时会缺少方向。

建议：每个章节索引至少补“本章问题、学习目标、建议阅读顺序、可跳过/需预备的内容”。如果只是导航占位，建议暂时隐藏。

37 个页面文字依赖图示但没有实际图片

受影响文件：

• content/courses/en/sequences/applications/compound-interest.mdx
• content/courses/en/sequences/applications/geometric-problems.mdx
• content/courses/en/sequences/applications/index.mdx
• content/courses/en/sequences/applications/loan-repayment.mdx
• content/courses/en/sequences/applications/population-growth.mdx
• content/courses/en/sequences/arithmetic-sequence/general-term.mdx
• content/courses/en/sequences/arithmetic-sequence/index.mdx
• content/courses/en/sequences/arithmetic-sequence/properties.mdx
• content/courses/en/sequences/arithmetic-sequence/sum-formula.mdx
• content/courses/en/sequences/exercises/advanced-exercises.mdx
• content/courses/en/sequences/exercises/basic-exercises.mdx
• content/courses/en/sequences/exercises/index.mdx
• 另有 25 个同类文件未列出。

正文出现“如下图”“观察图像”“示意图”等表达，但页面中没有可见图片或本地图示。对几何、架构、流程、算法类课程，这会明显降低理解速度。

建议：补本地图、组件图或至少给出可独立理解的文字兜底说明。

5 个练习页缺少答案或反馈

受影响文件：

• content/courses/en/sequences/exercises/advanced-exercises.mdx
• content/courses/en/sequences/exercises/basic-exercises.mdx
• content/courses/en/sequences/exercises/index.mdx
• content/courses/en/sequences/exercises/intermediate-exercises.mdx
• content/courses/en/sequences/index.mdx

课程包含练习或自测，但缺少答案、提示、常见错误或判断标准。自学读者做完后无法确认是否理解正确。

建议：为每个练习补参考答案折叠区；复杂题至少提供提示、关键步骤和最终结果。

8 个页面元数据不完整

受影响文件：

• content/courses/en/sequences/applications/index.mdx
• content/courses/en/sequences/arithmetic-sequence/index.mdx
• content/courses/en/sequences/exercises/index.mdx
• content/courses/en/sequences/geometric-sequence/index.mdx
• content/courses/en/sequences/mathematical-induction/index.mdx
• content/courses/en/sequences/recurrence-relation/index.mdx
• content/courses/en/sequences/sequence-limit/index.mdx
• content/courses/en/sequences/sequence-sum/index.mdx

缺少 title、课程/章节 description 或正文页 order 会影响导航、SEO、排序和卡片摘要。

建议：补齐标题、描述和排序字段，并确保同一目录下的排序规则稳定。

6 个同级页面共享相同 order

受影响文件：

• content/courses/en/sequences/arithmetic-sequence/general-term.mdx
• content/courses/en/sequences/arithmetic-sequence/index.mdx
• content/courses/en/sequences/geometric-sequence/index.mdx
• content/courses/en/sequences/geometric-sequence/sum-formula.mdx
• content/courses/en/sequences/sequence-sum/dislocation-subtraction.mdx
• content/courses/en/sequences/sequence-sum/index.mdx

同一目录下多个页面使用相同 order，导航可能依赖文件名或构建器默认顺序，导致读者看到的章节顺序不稳定。

建议：同级页面使用唯一递增 order；若需要章节级排序和文章级排序，拆分字段或明确排序策略。

P2：阅读体验问题

暂未发现明显的阅读体验 P2 问题。

建议修复顺序

1. 补齐或隐藏空骨架正文页。
2. 补课程首页和章节索引导读。
3. 统一同级页面 order。
4. 给练习补答案或提示。
5. 补关键图示和文字兜底。
