For more information, see Creating and Announcing a Course Using Publisher (edx.org Courses).
In a problem component, you use special formatting to identify the specific question that learners will answer by selecting options or entering text or numeric responses.
This text is referred to as the accessible label because screen readers read all of the text that you supply for the problem and then repeat the text that is identified with this formatting immediately before reading the answer choices for the problem. This text is also used by reports and Insights to identify each problem.
All problems require accessible labels.
For more information, see The Simple Editor.
An OLX (open learning XML) editor in a problem component that allows you to create and edit any type of problem. For more information, see The Advanced Editor.

The part of a unit that contains your actual course content. A unit can contain one or more components. For more information, see Developing Course Components.
You can define alternative course content to be delivered to different, randomly assigned groups of learners. Also known as A/B or split testing, you use content experiments to compare the performance of learners who have been exposed to different versions of the content. For more information, see Overview of Content Experiments.
content-specific discussion topic
A category within the course discussion that appears at a defined point in the course to encourage questions and conversations. To add a content- specific discussion topic to your course, you add a discussion component to a unit. Learners cannot contribute to a content-specific discussion topic until the release date of the section that contains it. Content-specific discussion topics can be divided by cohort, so that learners only see and respond to posts and responses by other members of the cohort that they are in.
For more information, see Working with Discussion Components. For information about making content-specific discussion topics divided by cohort, see Setting up Discussions in Courses with Cohorts.

Optional discussion categories that you create to guide how learners find and share information in the course discussion. Course-wide discussion topics are accessed from the Discussion page in your course. Examples of course-wide discussion topics include Announcements and Frequently Asked Questions. Learners can contribute to these topics as soon as your course starts. For more information, see Creating Course Discussions and Create Course-Wide Discussion Topics.
If you use cohorts in your course, you can divide course-wide discussion topics by cohort, so that although all learners see the same topics, they only see and respond to posts and responses by other members of the cohort that they are in. For information about configuring discussion topics in courses that use cohorts, see Setting up Discussions in Courses with Cohorts.

Discussion topics that course teams add directly to units. For example, a video component can be followed by a discussion component so that learners can discuss the video content without having to leave the page. When you add a discussion component to a unit, you create a content-specific discussion topic. See also Content Specific Discussion Topic.
For more information, see Working with Discussion Components.
discussion thread list
The navigation frame that appears at one side of the Discussion page in the LMS. The discussion thread list shows the discussion categories and subcategories in the course. When you select a category, the list shows all of the posts in that category. When you select a subcategory, the list shows all of the posts in that subcategory. Select a post to read it and its responses and comments, if any.

An embargo is an official ban on trade or commercial activity with a particular country. For example, due to U.S. federal regulations, edX cannot offer certain courses (for example, particular advanced STEM courses) on the edx.org website to learners in embargoed countries. Learners cannot access restricted courses from an embargoed country. In some cases, depending on the terms of the embargo, learners cannot access any edX courses at all.

The enrollment track specifies the following items about a course.
The type of certificate, if any, that learners receive if they pass the course.
Whether learners must verify their identity to earn a certificate, using a webcam and a photo ID.
Whether the course requires a fee.
audit: This is the default enrollment track when learners enroll in a course. This track does not offer certificates, does not require identity verification, and does not require a course fee.
professional: This enrollment track is only used for specific professional education courses. The professional enrollment track offers certificates, requires identity verification, and requires a fee. Fees for the professional enrollment track are generally higher than fees for the verified enrollment track. Courses that offer the professional track do not offer a free enrollment track.
If your course is part of a MicroMasters or professional certificate program, your course uses the verified track. These courses do not use the professional enrollment track.
verified: This enrollment track offers verified certificates to learners who pass the course, verify their identities, and pay a required course fee. A course that offers the verified enrollment track also automatically offers a free non-certificate enrollment track.
honor: This enrollment track was offered in the past and offered an honor code certificate to learners who pass the course. This track does not require identity verification and does not require a fee. Note, however, that as of December 2015, edx.org no longer offers honor code certificates. For more information, see News About edX Certificates.
credit: In this enrollment track, learners who pass the course and comply with additional requirements, including identity verification, can receive academic credit for the course. For more information, see Academic Course Credit.
