A GoGuardian Teacher Scene is made up of several components. This reference covers each one. ## Scene Information | Field | Description | | --------------- | --------------------------------------------------------------------------------------------------------------------------- | | **Name** | A descriptive label for the Scene. Scenes are displayed in the order they were created, starting with the oldest. Required. | | **Description** | A note about when or how the Scene is used. Optional. | | **Color** | A color label that visually distinguishes the Scene from others. Optional. | GoGuardian Teacher Scene page Allow List Scene interface GoGuardian Teacher Scenes customization user interface GoGuardian Teacher Scene rule entry interface GoGuardian Teacher Scene editing interface ## Filter List Type Each Scene uses one of 2 filter list types: | Type | Behavior | | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Allow List** | Students can only access sites on the list. All other sites are blocked. GoGuardian Admin policies can further restrict access beyond what the Allow List permits. | | **Block List** | Students can access any site except those explicitly added to the list. GoGuardian Admin policies continue to block sites even when a Block List is active. | GoGuardian Teacher Allow List interface GoGuardian Teacher Block List Interface ## Allowed and Blocked URLs Sites are added to a Scene by entering a URL or keyword into the search field. GoGuardian Teacher returns the site plus related suggestions. Click **Add** to include any of them. You can add: * **Full websites**: affects the entire site and all pages within it * **Website paths**: affects only a specific section of a site * **Individual webpages**: affects a single page Sites added to an Allow List are the only sites students can access. Sites added to a Block List are the only sites students are prevented from accessing (in addition to those blocked by GoGuardian Admin). Websites blocked by GoGuardian Admin cannot be allowed through an Allow List Scene. Teachers do not have visibility into which sites GoGuardian Admin is blocking from within GoGuardian Teacher. Allowed and Blocked URLs Allowed and Blocked URLs ## Quick Lists Quick Lists are pre-built collections of URLs that can be added to or removed from a Scene all at once. | Quick List Type | Who Manages It | | -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **GoGuardian Quick Lists** | Built and maintained by GoGuardian. Commonly used for sites with many subdomains, for example, a Google Docs Quick List that includes all required Google Docs domains. Google Docs alone uses 21 subdomains and redirects. GoGuardian Quick Lists are typically used with Allow Lists. Adding a GoGuardian Quick List, such as the Google Docs Quick List, to a Block List blocks all of those services. | | **District Quick Lists** | Created and managed by a Super User in your organization through Org Management. Available to all teachers in the district. | | **Custom Quick Lists** | Created by individual teachers. Reusable across multiple Scenes. | Quick Lists icon Example Quick List interface Quick Lists Custom Quick List interface ## Auto-Open Tabs URLs added to the Auto-Open section open automatically on student devices when the Scene is applied. * For **Allow Lists**: add the site to the allowed list first, then check the **Auto-Open** checkbox that appears next to it. * For **Block Lists**: use the **Auto-Open Tabs** section in the Block List editing interface. Tabs only auto-open if the student has a Chrome window open. If students do not receive the tabs, ask them to open a Chrome window.

When the Scene is applied, students cannot open more than the set number of tabs. Any tabs over the limit are closed automatically when the Scene is applied. No limit is set by default. The tab limit is only active while the Scene is applied to the session. GoGuardian Teacher Scene Tab Limit interface ## Advanced Filtering Advanced Filtering adds exceptions to a Scene's allow or block rules. Use it to allow or block an entire domain while carving out specific exceptions. **Example:** Adding `*google.com*` to an Allow Mode Scene allows all Google services. Adding `sites.google.com` as an Advanced Filter exception blocks that specific Google service while keeping all others accessible.
