The student sees the blocks from top to bottom in the order you arranged them. You can also pin files to the lesson. They are shown at the very top of the content. ## Where to edit the content Open the lesson and go to the **Content** section (“Content builder”). Lessons and modules with content have this section. A header module has no content. All changes are saved automatically. ## Block types You add blocks with the buttons below the list of blocks. There are 11 types: | Block | What it is for | | - | - | | **Editor** | Text, images, tables, links, formulas and quotes. To pick a tool, press `/` | | **Video** | Video by link or file upload | | **Audio** | An audio track: upload a file or record from the microphone with the **Record** button | | **Button** | A button that opens a link or a page of the school app | | **Message** | Text shown as chat messages from a sender | | **Checklist** | A list of steps for breaking down a complex task | | **Separator** | A **Next** button: the content below opens after a click | | **Quiz task** | A question with auto-check right inside the theory | | **Notion** | A public Notion page inside the lesson | | **Iframe** | Embedding external content: websites, services, maps, presentations | | **SCORM** | Uploading and launching a SCORM package in `.zip` format | ### Video Upload a video file or paste a link. YouTube, Vimeo, Kinescope and direct links to video files are supported. You can also fill in **Video title** and **Description and timecodes**, for example `00:05 - Part 1`. After the upload, the platform calculates the video duration. The duration is needed to count views: if the lesson has **Video watch threshold** turned on, the student cannot move on until they watch the video to the required percentage. Learn more in [Lesson and practice settings](https://faq.exode.biz/en/general/lessons-modules/settings.md). Protection against screen recording and copying is turned on in the course settings. Learn more in [Content protection](https://faq.exode.biz/en/general/courses/content-protection.md). ### Quiz task A quiz task is a short self-check question inside the theory. Seven types are available: single choice, multiple choice, logical choice, short answer, arrange the words, fill in the blanks and matching. * The answer is checked right away, and the student sees “Correct” or “Incorrect”. * You can set **Message for the correct answer** and **Message for the incorrect answer**. * The **Hide blocks below** setting hides the content under the task until the student answers. If a message is set, the blocks below are always hidden until the answer. * A quiz task gives no points, does not affect lesson completion and does not go to the curator for review. If you need grading, attempts and review, use [practice](https://faq.exode.biz/en/general/lessons-modules/practice). ### Notion Paste the public link to the page, not the address from the browser. In Notion, click **Share** → **Publish** and copy a link like `https://my-space.notion.site/...`. If you changed the page in Notion, click **Refresh content**. ### Iframe Fill in **Embed URL** and the base width and height in pixels. You can use the `{{userId}}`, `{{courseId}}` and `{{lessonId}}` templates in the address. When the block is shown, they are replaced with real values. ### Message and button * In the **Message** block, set the sender name, avatar and message texts. The `{{userId}}`, `{{firstName}}` and `{{supportUrl}}` templates are supported. * In the **Button** block, set the text, color and **Action**: open a link or a page of the school app. A link can open in a new tab. The “Transform the button into a "message" view after pressing” option replaces the button with a message containing its text. ### SCORM **1. Add a SCORM block** Click **SCORM** in the list of blocks. **2. Upload the package** Click **Upload SCORM package** and select a `.zip` archive. While the package is being processed, students see “Presentation is being processed”. **3. Check the result** When processing is over, the package is ready to launch. If processing failed, upload the package again. You can replace a ready package with the **Replace SCORM package** button. The student launches the package with the **Start learning** button and sees their progress. Lessons with SCORM have a completion threshold and a requirement to pass the quiz in their settings. Learn more in [Lesson and practice settings](https://faq.exode.biz/en/general/lessons-modules/settings.md). Supported package formats, completion statuses and where to see the results are covered in [SCORM packages](https://faq.exode.biz/en/corporate/scorm-import.md). ## Working with blocks * **Add a block**: click the type you need below the list of blocks. The new block appears at the end. * **Block title**: an optional field in the block header. * **Change the order**: use the up and down arrows in the block header. * **Delete a block**: through the block header, with confirmation. After deletion, a notification with the **Recover** button appears. ## Pinned files You can attach files of any type to a lesson: guides, presentations, archives. They are placed at the very top of the lesson content in the “Pinned attachments” block. 1. In the **Content** section, click **Add files**. 2. Upload one or more files. 3. Rename a file if needed: **Change file name** → **Attachment title**. To remove a file, click **Delete file**. ## Translating the content If the course has several languages, a **Content language** switcher and a counter “Blocks translated: N of M” appear above the builder. * New blocks are created only in the primary language. In other languages, you can only change the content of existing blocks. * Until a block is translated, students with another language see the primary content. * Some blocks are not translated. Students in all languages see the changes in them. * You can hide a block for a specific language. ## Brief summary (AI) The **Settings** of a lesson with content have a **Brief summary (AI)** field. Fill it in yourself or click **Generate with AI**, and a summary is written from the lesson content. If the field is filled in, the student sees a “Brief summary from AI” card in the lesson. * Generation is available if the school's tariff includes the “AI homework generation” feature. Learn more in [Tariffs](https://faq.exode.biz/en/online-schools/getting-started/subscription-plans.md) (commercial schools only). In a corporate school, your Exode manager changes the tariff: see [Company connection and setup](https://faq.exode.biz/en/corporate/setup.md). * Generation does not start for an empty lesson: “Write the lesson first — there is nothing to summarize”. * The limit is 60 generations per day. ## Frequently asked questions > **Which video links are supported?** > > YouTube, Vimeo, Kinescope and direct links to video files. You can also upload the video as a file. > **How do I swap blocks?** > > Use the up and down arrows in the block header. Blocks cannot be dragged. > **I deleted a block by mistake. Can I bring it back?** > > Yes, right after deletion click **Recover** in the notification that appears. > **Does a quiz task in the theory affect lesson completion?** > > No. A quiz task is a self-check. It gives no points and does not block moving on. The exception is the **Hide blocks below** setting: the content under the task opens only after the answer. > **Why is the Notion block not displayed?** > > Most likely, you pasted the link from the address bar instead of the public one. Publish the page in Notion through **Share** → **Publish** and paste a link like `https://my-space.notion.site/...`. > **The student sees “Presentation is being processed”. What should I do?** > > The SCORM package is still being unpacked. Wait until processing is over. If processing ended with an error, upload the package again. > **Where will the student find the attached files?** > > At the very top of the lesson, in the “Pinned attachments” block. > **Why can't I add a new block in another language?** > > Blocks are created only in the primary language of the course. Switch to the primary language, add the block, then go back to the language you need and translate its content. *** *Updated: 2026-10-15 18:08 UTC* This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
