教師は、Classroom アドオンと CourseWork API を使用して、どこからでも課題の割り当てと採点を行うことができます。Classroom アドオンを使用すると、教育者は Google Classroom のインターフェース内でお気に入りの EdTech ツールを統合できます。教師は Google Classroom 内でサードパーティのコンテンツを選択、割り当て、採点できます。これにより、教師と生徒はシームレスな学習体験を得ることができます。
アドオンは、他の Classroom API 機能を補完します。アドオンを使用すると、教師や生徒は Google Classroom を離れることなくコンテンツにアクセスできます。さまざまな統合を採用して、より多くの場所からコンテンツにアクセスできるユーザー フレンドリーな方法を提供します。
デベロッパーは、 Google Workspace Marketplace を通じて配布されるアドオンアプリケーションを作成します。教師は自分の Google Workspace for Education アカウントにアプリをインストールできます。また、Google Workspace 管理者は教師ユーザー向けにアプリをインストールできます。教師はアプリケーションを操作して添付ファイルを作成します。
Classroom アドオンのメリット
Classroom アドオンを開発する主なメリットは次のとおりです。
見つけやすさ
CourseWork API とは異なり、Classroom アドオンは Google Classroom に直接表示されるだけでなく、Google Workspace Marketplace(利用しているすべての Google プロダクトのツールを管理者が管理するためのハブ)にも表示されます。

Teachers can select,\nassign, and grade third-party content within Google Classroom. The result is a\nseamless learning experience for teachers and students.\n\nAdd-ons complement other Classroom API features. Add-ons let teachers\nand students experience your content without having to leave Google Classroom.\nAdopt a variety of integrations to provide user-friendly ways to access your\ncontent from more places.\n\nClassroom add-ons are available to all teachers with Teaching \\&\nLearning or Plus [Google Workspace for Education licenses](//edu.google.com/intl/ALL_us/workspace-for-education/editions/compare-editions/).\n\nOverview\n--------\n\nAdd-ons allow users to create **attachments** on assignments,\nannouncements, or materials. These attachments open third-party content in\n**[iframes](/workspace/classroom/add-ons/get-started/iframes/iframes-overview)** in Google Classroom. The iframes open separate URLs depending on\nthe user type and Google Classroom context.\n\nDevelopers create add-on **applications** distributed\nthrough [Google Workspace Marketplace](//workspace.google.com/marketplace/category/works-with-classroom). Teachers can install\napplications to their own Google Workspace for Education account, or Google Workspace administrators\ncan install applications for their teacher users. Teachers then interact with\nthe application to create attachments.\n\nWhy Classroom add-ons\n---------------------\n\nThere are several key benefits to developing a Classroom add-on.\n\n### Discoverability\n\n- Unlike the CourseWork API, Classroom add-ons show up directly in Google Classroom as well on the [Google Workspace Marketplace](//workspace.google.com/marketplace/category/works-with-classroom) which is the hub for administrators to manage tools across all their Google products.\n- Through add-ons, teachers can discover new third party tools and foster discussions with their admins to encourage domain-wide usage.\n\n### Deeper and more streamlined experience\n\n- Our overall goal for Classroom add-ons is to extend the streamlined experience of Google Classroom to the third-party tech ecosystem. Classroom add-ons bring together the experiences of Classroom and the many tools that teachers, students, and admins are using every day.\n- By embedding third-party content throughout the Classroom workflow (assignment creation, student work, grading workflow), you enable deeper experiences for users.\n\n### Continued investments in developer experience\n\nGoogle is investing in the user experience beyond the CourseWork API. Add-ons\naddress core pain points that users have when using third-party learning tools:\n\n- **Centralize student work** - Students experience friction in their ability to balance the complexity of navigating too many systems and locations to do their schoolwork. With add-ons, students can directly access work in one place so that they can focus on their schoolwork instead of the technology.\n- **Grading** - Teachers have expressed that grading is time consuming, error prone, and difficult to manage across tools. Add-ons allows teachers to quickly access grades provided by third-party tools and combine those with additional feedback directly within Classroom.\n- **Google single sign-on (SSO)** - Teachers and students experience difficulty remembering logins for many different tools in their class. Add-ons simplify this by enabling users to sign in to third-party tools with just one account.\n- **Continued investment** - The Classroom add-ons and Classroom API are both strategic areas of investment for Google. Google is committed to their continued development and adoption.\n\nNext steps\n----------\n\nSee the following sections for detailed information about the add-ons benefits\nand development process.\n\n- [Get started](/workspace/classroom/add-ons/get-started/get-started-overview) - Detailed descriptions of the user experience, user journey, and developer journey\n- [Developer guides](/workspace/classroom/add-ons/developer-guides/developer-guides-overview) - Design and implementation details\n- [Add-on review process](/workspace/classroom/add-ons/developer-guides/review-process-overview) - Procedures for add-ons publication\n- [Developer walkthroughs](/workspace/classroom/add-ons/walkthroughs/walkthroughs-overview) - Step-by-step implementation guides with code examples\n- [Requirements](/workspace/classroom/add-ons/requirements) - The list of expectations for published add-ons"]]
