3. CodeOcean includes unit tests to provide feedback for learners and score their code. A unit test is defined as a program that either runs the learner’s code in a pre-defined way and compares the provided result with an expectation or the unit test parses the student’s source code and matches it against an exercise-defined string. While the code of the unit tests are hidden, learners can run the unit tests at any time and get instant feedback whether they passed or failed. If the unit tests fail the result is shown together with an error message defined by the MOOC instructors. On the one hand, this feedback helps people to help themselves and provides learners with a hint of their mistake. On the other hand, the automated scoring using unit tests is required to indicate progress for the learners. In the context of a MOOC with thousands of active learners, a manual review by the instructors is not feasible and peer-review of source code has not been implemented in CodeOcean so far.
4. In CodeOcean, learners can ask questions about their program directly within the platform and in context of their current program. Usually, MOOC platforms provide a forum to discuss questions. While this concept also works great for source code in general outside of a MOOC (cf. [StackOverflow](https://stackoverflow.com)), it is an additional barrier for novices to summarize their problem externally. To understand the problem, contextual information is generally of help for others to provide the current solution. When using a dedicated forum, learners are required to provide as much information as necessary to reproduce the issue which beginners might find difficult to identify. As a result, they might copy too few or too much information. In addition, early iterations of the Java courses showed that learners did not format their source code appropriate in forum posts (but as plain text), making it difficult to read. With _Request for Comments_, CodeOcean provides a built-in feature to ask a question in the context of an exercise, thus lowering the barriers to get help. CodeOcean presents the learner’s source code and error message together with the question to fellow students and allows them to add a comment specifically to one line of code. Hence, the previously described issue is solved with a dedicated forum.
CodeOcean is mainly used in the context of MOOCs (such as those offered on openHPI and mooc.house) and has been used by more than 60,000 users as of June 2020. CodeOcean is a stand-alone tool implementing the [Learning Tools Interoperability (LTI)](http://www.imsglobal.org/activity/learning-tools-interoperability) standard to be used in various learning scenarios. By offering an LTI interface, it is accessible from MOOC providers as well as other providers, such as the HPI Schul-Cloud. CodeOcean itself cannot be used directly by learners or other users than the MOOCs instructors or administrators.

- Once deployed, CodeOcean assumes to run exclusively under a (sub)domain. If you want to use it under a custom subpath, you can specify the desired path using an environment variable: `RAILS_RELATIVE_URL_ROOT=/codeocean`. Please ensure to rebuild all assets and restart the server to apply the new path.
