Without the App, the Respondus app can only be accessed on Windows 7,8, and 10 which are not also available on mobile devices. You can read a guide on how to install the browser on the Respondus website and understand more. One cannot install the lockdown browser app on android and iPhone devices because the app is not available on the Play Store or Apple store. Students can click submit when they finish the assignment. The students are then required to confirm the self-lock app which prevents the student from accessing other apps during the exam.These permissions have to be granted for monitoring and using audio when required. For the first time use, the students are required to allow the app to access the iPad’s camera and microphone.By clicking the “Take assignment” instruction the Respondus lockdown app will take you to a new window. One can then click through the assignment module to begin the assignment. Once the app is downloaded one will have to fill in the institution details.Access the App Store and search the lockdown browser app.Linear regression: TRUE, FALSE, FALSE | 0.024 Linear regression: FALSE, TRUE, FALSE | 0.531 Linear regression: FALSE, FALSE, TRUE | -0.861 In particular, we can easily extract the meta-information regarding the correct answers in all randomly generated exercises. This is not necessary but inspecting this object might be helpful when developing and testing new exercises. Moreover, to show that the object returned within R can also be useful we have assigned the output of exams2openolat() to an object rxm. The resulting output file is R-exams.zip. Rxm <- exams2openolat(elearn_exam, n = 3, name = "R-exams") This yields the file R-exams.xml that can be imported into Moodle.Īnalogously, a ZIP archive containing QTI 2.1 XML files (Question & Test Interoperability standard) for import into OpenOlat. set.seed()Įxams2moodle(elearn_exam, n = 3, name = "R-exams") Second, we generate a Moodle XML file with 3 random replications of each of the exercises. Rnw files could be used, yielding virtually identical output.

Knowledge quiz question with basic shufflingĬomputing the derivative of a function with randomized parameters Here, we use a collection of exercise templates that are all shipped within the R/exams package and that cover a broad range of different question types as well as different randomyly-generated content (shuffling, random parameters, R output, graphics, simulated data sets). In the following we focus on Moodle and OpenOlat, both of which provide very flexible and powerful assessment modules. R/exams provides suitable interfaces for all of these but the capabilities differ somewhat between the LMS. Popular LMS include the open-source systems Moodle, Canvas, OpenOlat, or Ilias or the commerical Blackboard system. The actual quiz/test/exam is then conducted in the LMS only, i.e., without the need to have R running in the background, because all exercises and corresponding solutions have been pre-computed and stored in the LMS. R/exams can support these scenarios by creating a sufficiently large number of randomized versions of dynamic exercises that can subsequently be imported into a learning management system (LMS).
