One Saturday afternoon, nine materials一个星期六下午，九件教材
Everyone asks how long it took. Four and a half hours. Here is exactly where the time went, what went wrong, and what I would tell a teacher trying it for the first time.大家都问花了多久。四个半小时。下面是时间到底花在哪里、哪里出了错，以及我会怎么跟第一次尝试的老师说。
It was the last of six Saturday afternoons on a course about making teaching materials with AI. The brief was simple: take one unit you actually teach, and make everything for it before you go home. I chose Melaka, because it is the unit I love most and teach least well.
The log
| Time | What I did | Took |
|---|---|---|
| 1:00 | Wrote the story in six scenes on paper, and the five facts students must keep. No computer. | 20 min |
| 1:20 | Fourteen paintings: the port, six scenes, five character portraits, a map, trade goods. One style for all of them. | 60 min |
| 2:20 | The film: six 15-second clips from the paintings, my 20-line narration, subtitles. | 90 min |
| 3:50 | The song: wrote the lyrics, made four versions, kept one. | 30 min |
| 4:20 | Class page, notes, timeline, the sorting game and the quiz. | 60 min |
| 5:20 | The check: every date and name against the textbook. | 10 min |
| Total, for nine materials | 4 h 30 |
The slide deck, the poster and the lesson plan came almost free at the end, because they reuse the paintings and the notes.
What went wrong
- A painting leaked into the film. The first clip of the founding scene opened on a still frame of the reference painting before it started moving. A third of a second, but students notice. I trimmed it.
- The song was too fast. I chose the prettiest version, not the clearest. Wrong test. I made it again.
- The first narration was too long for the pictures. Twenty lines in ninety seconds is tight. I cut adjectives until every line fit its scene.
What I would tell a first-timer
- Start with a pen, not a tool. Twenty minutes on paper saved me an hour of generating pictures I did not need.
- Pick one style and never change it. Fourteen pictures in fourteen styles look like fourteen different lessons.
- Write every word yourself. The narration and the lyrics are the teaching. Everything else is packaging.
- Never skip the check. It is the shortest step and the only one that protects your students.
You do not need to be good at drawing, editing or music. You need to know your subject, and be willing to check.
Every instruction I gave the tools that afternoon is in my prompt log, and the templates I use now are on the Resources page.
那是一门教老师用 AI 做教材的课程，六个星期六下午里的最后一个。任务很简单：挑一个你真的在教的单元，回家之前把它需要的东西全部做完。我选了马六甲，因为这是我最爱、却教得最不好的单元。
时间记录
| 时间 | 做了什么 | 用时 |
|---|---|---|
| 1:00 | 在纸上把故事写成六个场景，再写下学生必须记住的五个考点。不开电脑。 | 20 分钟 |
| 1:20 | 十四张画：港口、六个场景、五张人物肖像、一张地图、一张贸易货物。全部同一种画风。 | 60 分钟 |
| 2:20 | 影片：用画生成六段 15 秒的片段，加上我写的 20 句旁白，再加字幕。 | 90 分钟 |
| 3:50 | 歌：写歌词，生成四个版本，留下一个。 | 30 分钟 |
| 4:20 | 班级页、笔记、时间线、排序游戏和小测验。 | 60 分钟 |
| 5:20 | 检查：每个年份和名字对照课本。 | 10 分钟 |
| 九件教材，总共 | 4 小时 30 分 |
简报、海报和教案在最后几乎不花时间，因为它们重复用了那些画和笔记。
哪里出了错
- 一张画混进了影片。建国那一段的第一个片段，开始动之前先停在参考画上一下。只有三分之一秒，但学生看得出来。我把它剪掉了。
- 歌太快。我选了最好听的版本，不是最清楚的。标准选错了，只好重做。
- 第一版旁白太长，画面装不下。九十秒放二十句很紧。我一直删形容词，删到每一句都刚好配上它的场景。
我会怎么跟第一次尝试的老师说
- 先拿笔，不要先开工具。在纸上花二十分钟，省下我一小时去生成用不到的图。
- 选定一种画风，然后不要换。十四张画十四种风格，看起来就像十四堂不同的课。
- 每一个字都自己写。旁白和歌词才是教学，其他都是包装。
- 检查永远不能省。它是最短的一步，也是唯一能保护学生的一步。
你不需要会画画、会剪辑、会音乐。你需要懂你教的科目，并且愿意检查。
