23 June 2015

The following information reflects what is new in the edX Platform as of 23 June 2015.

Insights

All Problem Parts Now Combined

Learner submissions for problems that have more than one part are now counted only once, for the entire problem, rather than once for each part of the problem. In courses that include problems with differing numbers of questions, or parts, in each problem, the resulting graph could be difficult to interpret.

For example, a course has an assignment that includes some problems with four parts, and other problems with only one part. The graph of the problem submissions for the assignment before this change appeared as follows.

The graph for the problem submission before all parts were combined.

Now, with submissions for each problem counted once, the graph for the same assignment in the course appears as follows.

Per­ Problem Performance Data

EdX Insights now makes it easier to see how many learners did well on assignments or on ungraded problems in course sections. In the performance graphs for graded content and ungraded problems, the number of correct and incorrect submissions received is now averaged by the number of problems.

Before this change was made, edX Insights presented totals rather than averages. In courses that include differing numbers of problems in each assignment, the resulting graph could be difficult to interpret.

For example, the first homework assignment in a course has four problems, the second has six problems, the third has five problems, and so on. The graph of the homework assignment submissions for the course before this change appeared as follows.

Now, with the change to average submissions by the number of problems in each assignment, the graph for the same course appears as follows.

Bug Fixes

  • Learners aged 26 years are now correctly included in the 26-40 age range.
  • The Section Submissions report for Ungraded Problems now reports the number of problems in each section. Previously, the number of subsections in the section was reported in error.

Documentation

Documentation for edX Partners

Building and Running an edX Course

The Accessibility Best Practices Guidance for Content Providers section has been expanded and moved to the top level of the guide.

Using edX Insights

The Student Performance section is updated to reflect that submission data is now averaged rather than summed.

Documentation for Open edX Users

The docs.edx.org website now includes a section for the latest version of the Open edX guides. These guides are available in addition to guides for the Open edX Birch release, and offer the most up-to-date documentation available for features in the Open edX platform.

Installing, Configuring, and Running the Open edX Platform

The new Enabling Custom Courses section describes how to configure the Open edX Platform to allow users with the right permissions to create custom courses.
