Moodle is a free and open-source learning management system (LMS). Moodle is used for blended learning, distance education, flipped classroom and other online learning projects in schools, universities, workplaces and other sectors.

Moodle is used to create custom websites with online courses and allows for community-sourced plugins.

(From Wikipedia, shortened)

Currently, there are two plugins for Moodle in Test of English website.

Audio Response is a Quiz > Question Type plugin. It is for recording students' spoken responses. There is already a similar plugin for this task in Moodle MarketPlace (Record audio/video question type) and it can be used to record sound or video. The main difference between Record Audio/Video and Audio Response is that the audio controls for Start, Pause, or Replay are not displayed in Audio Response.  Recording starts and finishes automatically.

Split Page is a Course Format plugin. It was designed for standardized language test courses. In a standardized test like the TOEFL iBT, when there is a reading passage, for example, the reading passage and the related question are displayed side-by-side on the page. On an ordinary Moodle quiz page, this is not possible. Also, a Moodle quiz is displayed with an information box next to it. In Split Page course format, if there is a "Description" and any other type of question on one page, this page is "split" into two - with "Description" on the left and the other question on the right. Also, the information box is not displayed.
