However, if CodeRunner-based quizzes are to be used for tests and final exams, a separate Moodle server is recommended, both for load reasons and so that various Moodle communication facilities, like chat and messaging, can be turned off without impacting other classes.Ī single 4-core Moodle server can handle an average quiz question submission rate of about 60 quiz questions per minute while maintaining a response time of less than about 3 - 4 seconds, assuming the student code itself runs in a fraction of a second.

The architecture allows easy extension to other languages.ĬodeRunner can safely be used on an institutional Moodle server, provided that the sandbox software in which code is run ("Jobe") is installed on a separate machine with adequate security and firewalling. Other courses using Moodle/CodeRunner include:ĮMTH171 Mathematical Modelling and ComputationĬodeRunner currently supports Python2 (considered obsolescent), Python3, C, C++, Java, PHP, JavaScript (NodeJS), Octave and Matlab. The second year C course (ENCE260) of around 200 students makes similar use of CodeRunner using C questions and a third year Civil Engineering course (ENCN305), taught in Matlab, uses CodeRunner for all labs and for the mid-semester programming exam. The final exams for COSC121 have also been run using Moodle/CodeRunner since November 2014. Laboratory work, assignment work and mid-semester tests in the introductory first year Python programming course (COSC121), which has around 500 students in the first semester and 300 in the second, are all assessed using CodeRunner questions. However, it is also possible to configure CodeRunner questions so that the mark is determined by how many of the tests the code successfully passes.ĬodeRunner and its predecessors pycode and ccode has been in use at the University of Canterbury for about six years, running over a million student quiz question submissions in Python, C, JavaScript, PHP, Octave and Matlab. The mark for a set of questions in a quiz is then determined primarily by which questions the student is able to solve successfully and then secondarily by how many submissions the student makes on each question.
In the typical 'all-or-nothing' mode, all test cases must pass if the submission is to be awarded any marks. If not, students can resubmit, typically for a small penalty. Regardless of the behaviour chosen for a quiz, CodeRunner questions always run in an adaptive mode, in which students can click a Checkbutton to see if their code passes the tests defined in the question. However, the focus throughout most of this document will be on programming questions, where the students' code is being graded. CodeRunner questions have also been used in other areas of computer science and engineering to grade questions in which many different correct answers are possible and a program must be used to assess correctness.

By far the most common use of CodeRunner is in programming courses where students are asked to write program code to some specification and that code is then graded by running it in a series of tests. Subscribe yourself to this forum if you wish to receive such news.ĬodeRunner is a Moodle question type that allows teachers to run a program in order to grade a student's answer. The second quiz shows only a few simple C and Java questions.Ī forum for exchange of question ideas and suggestions, bug-reports or anything else related to CodeRunner. The Python quiz is recommended to give you a feel for CodeRunner's capabilities, even if you don't understand Python3 the questions could (for the most part) be written in any of the supported Languages (Python2, Python3, C, C++, Java, PHP, JavaScript, Octave).
Don't worry, we won't spam you as a consequence. You'll be asked to register as a user on the site first, but this is painless and straightforward. To see how CodeRunner quizzes behave, try taking the Python3 demo quiz. Entonces ellos pueden corregir su código y re-enviarlo, típicamente con una pequeña penalización. Normalmente se usa el comportamiento adaptativo de Moodle los estudiantes pegan su código en respuesta a cada pregunta de programación y obtienen sus resultados del caso de prueba inmediatamente. Su uso esperado principal es en cursos de programación aunque puede usarse para calificar cualquier pregunta para la cual la respuesta sea texto.
