Educational Presentation Design

教育演示文稿设计

Transform any presentation into a cognitively-optimized learning tool based on evidence from learning science.

基于学习科学的实证研究，将任何演示文稿转化为认知优化的学习工具。

Core Philosophy: Minimize Cognitive Load

核心理念：最小化认知负荷

Prime Directive: Every design decision must serve learning by:

Reducing extraneous load (eliminate distractions)
Managing intrinsic load (chunk complex content)
Optimizing germane load (maximize mental resources for actual learning)

Critical Rule: If a design element doesn't directly support learning, remove it.

首要准则：每一项设计决策都必须通过以下方式服务于学习：

减少外在认知负荷（消除干扰）
管理内在认知负荷（拆分复杂内容）
优化关联认知负荷（最大化用于实际学习的心智资源）

关键规则：如果某个设计元素不能直接支持学习，就移除它。

Essential Principles (Non-Negotiable)

核心原则（不可妥协）

Mayer's 3 Most Critical Principles

Mayer三大核心原则

1. Coherence Principle ⭐ MOST IMPORTANT

1. 一致性原则（Coherence Principle）⭐ 最为重要

Rule: Exclude all extraneous material - no decorative clipart, busy backgrounds, or irrelevant details. Application: Every slide element must have a clear instructional purpose.

规则：剔除所有无关内容——无装饰性剪贴画、杂乱背景或无关细节。应用：幻灯片上的每一个元素都必须有明确的教学目的。

2. Redundancy Principle ⭐ CRITICAL

2. 冗余原则（Redundancy Principle）⭐ 关键

Rule: Do NOT put paragraphs of text on slides that will be read aloud. Why: Creates "cognitive channel war" - audience can't read and listen simultaneously. Solution:

Visuals + narration = GOOD ✅
Visuals + text wall + narration = COGNITIVE OVERLOAD ❌
Move all paragraph text to speaker notes
Slides should have: keywords, graphics, or charts only

规则：请勿将长篇文本放在幻灯片上并同时朗读。原因：会引发「认知通道冲突」——受众无法同时阅读和聆听。 解决方案：

视觉素材 + 旁白 = 合理 ✅
视觉素材 + 大段文本 + 旁白 = 认知过载 ❌
将所有段落文本移至讲者备注
幻灯片仅保留：关键词、图表或图形

3. Segmenting Principle ⭐ ESSENTIAL

3. 拆分原则（Segmenting Principle）⭐ 必备

Rule: Break content into user-paced chunks using progressive disclosure or multiple slides. Application: Never overwhelm with one dense slide - chunk across 3-5 slides instead.

For all 12 Mayer principles with detailed applications, read

references/quick-reference.md

规则：通过渐进式展示或多页幻灯片，将内容拆分为用户可自主掌控的模块。应用：切勿用单页密集幻灯片 overwhelm 受众——改为拆分为3-5页幻灯片。

如需了解Mayer全部12项原则及详细应用，请阅读

Macro-Structure: Gagné's 9 Events Framework

宏观结构：Gagné教学九事件框架

Every educational presentation MUST follow this structure:

所有教育演示文稿必须遵循以下结构：

Event 1: Gain Attention

事件1：吸引注意力

Thought-provoking question, surprising statistic, or compelling case study
Stimulates curiosity and focus

发人深省的问题、令人惊讶的数据或引人入胜的案例研究
激发好奇心与专注力

Event 2: Inform Learners of Objectives

事件2：告知学习者目标

"By the end of this session, you will be able to..."
Use measurable action verbs (Analyze, Compare, Apply, Evaluate, Create)

「本次课程结束后，你将能够……」
使用可衡量的动作动词（分析、比较、应用、评估、创造）

Event 3: Stimulate Recall of Prior Learning

事件3：唤醒已有知识

Poll question: "What do you already know about X?"
Activates existing knowledge as foundation

投票问题：「你对X已经了解哪些内容？」
激活已有知识作为学习基础

Event 4: Present the Content

事件4：呈现内容

Main content slides with visuals + narration (not text walls)
Break into digestible 3-5 minute chunks
Apply progressive disclosure

主内容幻灯片搭配视觉素材 + 旁白（无大段文本）
拆分为3-5分钟的易理解模块
应用渐进式展示

Event 5: Provide Learning Guidance

事件5：提供学习指导

Worked examples, non-examples, analogies, case studies
Graphic organizers and mnemonics

实例演示、反例、类比、案例研究
图形组织者与记忆技巧

Event 6: Elicit Performance

事件6：引导实践

"Try this problem" or "Discuss with your neighbor"
Interactive quiz or application exercise (non-graded)

「尝试解决这个问题」或「与邻座讨论」
互动测验或应用练习（非计分）

Event 7: Provide Feedback

事件7：提供反馈

Correct answer with explanation
Model of ideal response and common mistakes to avoid

带有解释的正确答案
理想回应范例及需避免的常见错误

Event 8: Assess Performance

事件8：评估学习成果

Formal quiz, project prompt, or final presentation request
Measures if objective was met

正式测验、项目任务或最终演示要求
衡量是否达成学习目标

Event 9: Enhance Retention and Transfer

事件9：强化留存与迁移

Final summary and transfer question: "How will you use this in your work?"
Real-world problem to solve

For detailed templates for each event, read

references/slide-templates.md

最终总结及迁移问题：「你将如何在工作中应用所学？」
真实场景问题求解

Micro-Design: C.R.A.P. Principles

微观设计：C.R.A.P.原则

1. Contrast

1. 对比（Contrast）

Create visual hierarchy with strong differences:

Large title (36-44pt) vs. smaller body (24-32pt)
Bright accent color on neutral background
Bold vs. regular weight

通过强烈差异构建视觉层级：

大标题（36-44号） vs 小正文（24-32号）
中性背景搭配明亮强调色
粗体 vs 常规字重

2. Repetition

2. 重复（Repetition）

Reuse same fonts, colors, and layouts:

Consistent title placement
Same color palette on every slide
Maximum 2 fonts for entire deck

重复使用相同字体、颜色与布局：

标题位置一致
所有幻灯片使用相同调色板
整个演示文稿最多使用2种字体

3. Alignment

3. 对齐（Alignment）

Nothing is placed arbitrarily:

Use invisible grid (turn on guides)
Left-align body text (never center paragraphs)
Connect every element to another

无任意放置的元素：

启用隐形网格（打开参考线）
正文左对齐（切勿居中段落）
每个元素都与其他元素建立关联

4. Proximity

4. 亲密性（Proximity）

Group related items close together:

Place labels directly next to graphics
Use whitespace to separate unrelated groups

For detailed C.R.A.P. applications, read

references/quick-reference.md

将相关元素紧密分组：

标签直接放置在图形旁
使用空白分隔不相关组

如需C.R.A.P.原则的详细应用，请阅读

references/quick-reference.md
