🎓 Gem 和 Skill 到底差在哪？
先用一個比喻抓住重點，再看教學現場怎麼用最有效。
🏫
Gem 像「專科教室」
- 每個 Gem 都是一間獨立的聊天室
- 要用它，得先「走進那間教室」（打開那個 Gem）
- 一次只能待在一間
🧰
Skill 像「隨身帶著的工作守則卡」
- 在任何對話裡打
@就能拿出來 - 對話內容對得上時，Gemini 會自己拿出來用
- 一次可以拿好幾張一起用
💡 指令本身沒變。你寫給 Gem 的內容，幾乎可以原封不動變成 Skill。真正的差別在「怎麼叫出來」和「能不能一起用」，唯一要新寫的是一句「什麼時候該用我」的描述。
一張表看懂
| Gems | Skills | |
|---|---|---|

Skill 的三招
①
@ 手動觸發
在任何對話打 @，選單會列出你的技能，點一下就套用。例如正在跟 Gemini 討論下週的閱讀課，打 @exit-ticket 就能接著產出三題出場券，不用另開 Gem、重貼課文。
②
自動觸發
連 @ 都不用打。描述寫「當老師要產出評分規準時使用」，你只要說「幫我做這份報告的 rubric」，Gemini 就會自己套用。所以描述是 Skill 的靈魂，這個工具的轉換和打造分頁都會幫你寫。
③
連擊 combo 技
同一個對話裡連續叫出好幾個技能：先產出教案，再分三層練習，最後出出場券。Skill 的指令裡也可以點名其他 Skill，串成固定流程。
🔗 連擊範例：一個對話完成備課流水線
@lesson-plan
產出教案
@tiered-practice
三層練習
@exit-ticket
出場券
💡 打 @ 之後，選單會同時列出「技能」和「連接器」（Google 文件、雲端硬碟、日曆、Keep 等），別點錯。還沒建立過任何技能的話，選單只會出現一行「技能」入口，不會有清單；建立或新增一個技能之後，就會列出來了。技能太多時，點「查看所有技能」。
⚠️ 很多老師會漏掉：你的 Gem 是在哪裡建的？
「給自己用的 Gem」和「給學生用的 Gem」，未來走的是兩條不同的路。
✅ 在 Gemini app（gemini.google.com）建的
- 會自動轉成 Skill（教育帳號：2027/6/1 或之後）
- 轉好後是「草稿」狀態，要檢查並啟用才會生效
- 想提早用，或趁機改得更好 →「把 Gem 轉成 Skill」分頁
🚫 在 Google Classroom 指派給學生，或透過 LMS 建的
- 包含透過 Gemini LTI 在 Canvas、Schoology、Moodle 建立的 Gem
- 不會自動轉換，而且 Skill 不能在 Classroom 或 LMS 裡使用
- 2027 年 6 月以後，這些 Gem 會停用
- → 改用 Classroom 的引導式學習（Guided Learning）或 Gemini Notebook（見下方）
三種情境，選對工具
👩🏫
老師自己的備課與行政
用 Skills（Gemini app）
- 教案：依課綱和你的教材產出完整課程
- 差異化：一次產出不同程度的鷹架與練習
- 形成性評量：把講義、簡報、PDF 變成小測驗
- 班級通訊、家長通知、行政公文
🧑🎓
學生在課堂上用，老師要看得到
用 Classroom 的引導式學習／Gemini Notebook
- 引導式學習：鎖定老師給的教材（最多 10 份），用提問一步步引導、不直接給答案（Classroom 版即將推出）
- 學生端會隱藏側欄、不能開新對話；老師看得到班級儀表板、參與趨勢和個別對話紀錄
- Gemini Notebook：把講義、簡報、影片變成學習指南、單字卡、心智圖、語音摘要
- 學生對教材唯讀，老師看得到誰打開、誰開始對話
🎒
學生自己的學習
學生自己的 Skills（學校開放後）
- 考前複習：把課堂筆記變成自我測驗和單字卡
- 看不懂的文章：改寫成白話摘要和生活化比喻
- 作文回饋：論點、段落組織、文法
- 💡 教學生寫一個好 Skill，本身就是一堂 AI 素養課
※ Classroom 的 Gemini 工具需要 Google Workspace for Education 帳號，並由學校管理員開啟；個人帳號無法使用。
📅 教育帳號的轉換時程
2026/9/30
個人帳號開放 Skills；教育帳號照常使用 Gems
2026/10/13
教育帳號的 Gemini app 開放 Skills（Gems 仍可建立和使用）。個人帳號不能再新增或編輯 Gem
2026/11/17
個人帳號的 Gem 自動轉成 Skill；教育帳號的 Gems 入口移到「設定」選單（仍可使用）
2027/6/1+
教育帳號的 Gem 自動轉成 Skill；Gemini app、Classroom、Gemini LTI 都不再提供 Gems
※ 依 Google for Education 2026 年轉換指南整理，實際開放時間以 Google 公告和學校管理員設定為準。
怎麼用才有最好的效果：7 個訣竅
做「會重複的事」
建 monthly-newsletter，不要建 october-parent-newsletter。
名稱用小寫動詞開頭
例如 build-lab-rubric，打 @ 跳出選單時一眼就知道它做什麼。
描述寫「當……時使用」，加上你平常的說法
例如「當我說『做實驗評分規準』或『建立實驗評分表』時使用」。Gemini 只靠名稱和描述判斷要不要用它。
不要建功能重疊的 Skill
兩個都能「出題」的 Skill，Gemini 會不知道該用哪一個。
把輸出格式寫死
例如「一律依照：1) 學習目標 2) 15 分鐘活動 3) 三題出場券」。
寫明「不要做什麼」
例如「句子不超過 15 個字，提供英語學習者句型開頭，不用艱澀術語」。
缺資料時要它先問
例如「如果我忘了說年級，先問我再產出教材」。
這些訣竅「從零打造 Skill」分頁都已經內建在步驟裡了。
建立 Skill 的 4 種方式
01
從頭建立（Create manually）
自己填名稱、描述、指令。本工具的「轉換」和「從零打造」分頁就是幫你準備這三格。
02
Create with Gemini
讓 Gemini 一步步陪你設計，適合還沒想清楚要做什麼的時候。
03
改推薦範本
從「Recommended」挑一個改成你的，例如 match-your-writing-style 會學你在 Workspace 裡的寫作語氣。
04
上傳檔案
.md、純文字、PDF、圖片都可以，也可以混著上傳。
可以先做這幾個
- @exit-ticket依今天的上課內容出三題出場券
- @tiered-practice同一份練習分成三個難度
- @reading-quiz課文 → 閱讀理解題＋詳解
- @writing-feedback用提問引導的作文回饋
- @build-rubric依任務產出評分規準
- @monthly-newsletter每月班級／家長通訊
先從你「每週都在做」的事開始，一次做一個，用一陣子再調整。
老師最常問的問題
▶ Skill 是不是比 Gem 難寫？
不會。指令內容一樣，只多一句「什麼時候用」的描述。看起來比較難，多半是因為 SKILL.md 的檔案格式，但走「Create manually」複製貼上的話，完全不用碰檔案。
▶ 轉換之後，舊的對話紀錄會不見嗎？
不會，在 Gemini 的聊天紀錄裡都找得到。
▶ 可以把 Skill 分享給同事嗎？
可以透過 Google 雲端硬碟分享。但 Skill 沒有「複製」按鈕，想改別人的 Skill 要下載、重新上傳再修改。匯入前記得先用「安全檢查」分頁看一下。
▶ 可以把 Skill 指派給學生嗎？
Classroom 裡不能指派 Skill。要讓學生在課堂上用 AI、老師又看得到過程，請用引導式學習或 Gemini Notebook。
▶ 學校帳號什麼時候能用 Skills？
依 Google for Education 的轉換指南，教育帳號的 Gemini app 預計從 2026/10/13 開始開放，但各校還是要看管理員的設定。
▶ 打 @ 之後只看到一行「技能」，沒有我的技能清單？
代表你的帳號還沒有啟用中的技能。先建立一個：用這個工具的「轉換」或「從零打造」分頁，或到 Gemini 的「設定 → 技能」新增一個推薦技能。建立之後再打 @，選單就會出現「技能」標題和你的技能名稱。從 Gem 自動轉過來的技能一開始是草稿，也要先啟用。
▶ Skill 能用 Canvas、Deep Research 嗎？
目前還不行。Canvas、Deep Research、引導式學習、生成影片與音樂這些工具，在 Skill 裡暫時不能用。Gem 依賴這些功能的話，先繼續用 Gem。

🎓 Gems vs. Skills: what's the difference?
One analogy to get the idea, then how to use Skills well in your teaching.
🏫
A Gem is like a specialist classroom
- Each Gem is its own separate chat room
- To use it, you have to "walk into that room" (open that Gem)
- You can only be in one room at a time
🧰
A Skill is like a procedure card you carry with you
- Pull it out in any chat by typing
@ - When the conversation matches, Gemini uses it automatically
- You can use several cards at once
💡 The instructions themselves don't change. What you wrote for a Gem can become a Skill almost word for word. The real differences are how you call it up and whether you can combine them. The only new thing to write is one sentence saying when to use it.

Three moves Skills can do
①
@ to call it up
Type @ in any chat and the menu lists your skills—click one to apply it. Planning next week's reading lesson? Type @exit-ticket and it continues with three exit-ticket questions—no new Gem, no re-pasting the text.
②
Automatic
You don't even need @. If the description says "Use when the teacher needs a rubric," just saying "make a rubric for this report" applies it automatically. That's why the description is the heart of a Skill—the Convert and Build tabs in this tool help you write it.
③
Combos
Chain several skills in one chat: build the lesson plan, split practice into three levels, then write the exit ticket. A Skill's instructions can even name other Skills to make it a routine.
🔗 Combo example: a lesson-prep pipeline in one chat
@lesson-plan
Lesson plan
@tiered-practice
Tiered practice
@exit-ticket
Exit ticket
💡 When you type @, the menu shows both Skills and connectors (Google Docs, Drive, Calendar, Keep and more)—make sure you pick the right one. If you haven't created any skills yet, the menu shows only a single "Skills" entry, not a list—create or add one and it will appear. With lots of skills, click See all skills.
⚠️ Easy to miss: where did you create your Gem?
Gems for yourself and Gems for students are headed down two different paths.
✅ Created in the Gemini app (gemini.google.com)
- Converts to a Skill automatically (education accounts: on or after June 1, 2027)
- It arrives as a draft—review and activate it to start using it
- Want to start early or improve it? → the "Convert a Gem" tab
🚫 Assigned to students in Google Classroom, or created through an LMS
- Including Gems created via Gemini LTI in Canvas, Schoology or Moodle
- Will not convert automatically, and Skills can't be used inside Classroom or an LMS
- These Gems stop working from June 2027
- → Move to Guided Learning or Gemini Notebook in Classroom (see below)
Three situations, three tools
👩🏫
Your own planning and admin
Use Skills (Gemini app)
- Lesson planning grounded in your curriculum and standards
- Differentiation: scaffolds and tiered practice in one go
- Formative assessment: turn readings, slides or PDFs into quick quizzes
- Class newsletters, parent notices, admin memos
🧑🎓
Students use it in class, with you watching
Use Guided Learning / Gemini Notebook in Classroom
- Guided Learning: locked to your materials (up to 10), guides with questions instead of giving answers (coming soon to Classroom)
- Students get a focused view with no new chats; you see class dashboards, engagement trends and individual transcripts
- Gemini Notebook: turns handouts, slides and videos into study guides, flashcards, mind maps and Audio Overviews
- Students get read-only sources; you see who opened it and who started a conversation
🎒
Students' own learning
Students' own Skills (once your school enables them)
- Exam prep: turn class notes into practice quizzes and flashcards
- Hard texts: plain-language summaries and relatable analogies
- Essay feedback: thesis, argument flow and mechanics
- 💡 Teaching students to write a good Skill is an AI-literacy lesson in itself
※ Gemini tools in Classroom need a Google Workspace for Education account and must be enabled by your admin; personal accounts can't use them.
📅 Timeline for education accounts
2026/9/30
Skills roll out to personal accounts; education users keep using Gems
2026/10/13
Skills roll out in the Gemini app for education users (Gems still work). Personal accounts can no longer create or edit Gems
2026/11/17
Personal-account Gems auto-convert to Skills; for education users the Gems entry point moves to the settings menu (still usable)
2027/6/1+
Education Gems auto-convert to Skills; Gems are no longer available in the Gemini app, Classroom or Gemini LTI
※ Based on Google for Education's 2026 transition guide. Actual availability depends on Google's announcements and your admin's settings.
Getting the best results: 7 tips
Build for repeatable tasks
Build monthly-newsletter, not october-parent-newsletter.
Use lowercase, action-word names
e.g., build-lab-rubric—when you type @, you can tell what it does at a glance.
Start the description with "Use when…" plus phrases you actually say
e.g., "Use when I ask to 'create a lab rubric' or 'build an experiment scoring guide'." Gemini relies only on the name and description to decide.
Avoid overlapping Skills
If two Skills both "make questions," Gemini won't know which one to use.
Spell out the output format
e.g., "Always format as: 1) Objective, 2) 15-minute activity, 3) 3-question exit ticket."
Say what NOT to do
e.g., "Keep sentences under 15 words, always include sentence starters for English learners, and avoid jargon."
Tell it to ask about missing details
e.g., "If I forget to state the grade level, ask me before creating the materials."
The "Build from Scratch" tab already walks you through all of these.
4 ways to create a Skill
01
Start from scratch (Create manually)
Fill in the name, description and instructions yourself. This tool's Convert and Build tabs prepare exactly those three fields.
02
Create with Gemini
Gemini guides you step by step—handy when you're not sure yet what you need.
03
Customize a recommended skill
Pick one under "Recommended" and make it yours, e.g., match-your-writing-style learns your voice from your writing in Workspace.
04
Upload a file
Upload a .md file, plain text, a PDF, an image, or a mix.
Good first Skills to build
- @exit-ticketThree exit-ticket questions from today's lesson
- @tiered-practiceThe same practice at three difficulty levels
- @reading-quizText → comprehension questions with explanations
- @writing-feedbackQuestion-led essay feedback
- @build-rubricA rubric for any task
- @monthly-newsletterMonthly class / parent newsletter
Start with something you do every week. Build one at a time and refine it as you use it.
Common questions
▶ Are Skills harder to write than Gems?
No. The instructions are the same; you just add one sentence about when to use it. What looks hard is usually the SKILL.md file format—but with "Create manually" you just copy and paste, no files involved.
▶ Will I lose my old Gem chats?
No. They stay in your main Gemini chat history.
▶ Can I share a Skill with colleagues?
Yes, via Google Drive. But there's no "make a copy" button—to adapt someone else's Skill, download it, re-upload it and customize it. Run it through the "Check Shared Skills" tab before importing.
▶ Can I assign a Skill to students?
Not in Classroom. For student-facing AI you can monitor, use Guided Learning or Gemini Notebook.
▶ When can school accounts use Skills?
According to Google for Education's transition guide, Skills roll out in the Gemini app for education users starting October 13, 2026—though it still depends on your school admin's settings.
▶ I typed @ but only see a single "Skills" entry, no list.
It means your account has no active skills yet. Create one first—with this tool's Convert or Build tab, or by adding a recommended skill under Settings → Skills in Gemini. Type @ again and you'll see a "Skills" heading with your skill listed. Skills converted from Gems start as drafts and need to be activated too.
▶ Do Skills work with Canvas or Deep Research?
Not yet. Canvas, Deep Research, Guided Learning, and video and music generation don't work with Skills for now. If your Gem depends on them, keep using the Gem for now.
