Overview of Browser Application
Respondus LockDown Browser is a client application that is installed to a local computer. It
provides a custom interface for the Internet Explorer (Windows) or Safari (Macintosh) software
that is already installed on the computer. It does not modify an existing copy of Internet Explorer
or Safari, but rather, installs a separate program that will display the custom interface when it is
started. Respondus LockDown Browser uses the same security features and service packs that
are currently installed for Internet Explorer or Safari. Installing Respondus LockDown Browser
won’t modify the current version of Internet Explorer or Safari in any way.
Respondus LockDown Browser creates a “locked” testing environment for Desire2Learn and
includes the following features:

Making Online Quizzes Even More Secure
Respondus LockDown Browser is an important tool for preventing cheating on online exams, but
it’s not a total solution. For example, students working from remote locations could use two
computers at once (one for taking the exam, the other for accessing other applications). Students
could use digital cameras to capture the screen content, send text messages on mobile phones,
or simply refer to printed notes.
Additional methods can be employed that further reduce the risk of cheating and ensure that
students know the course material. Each approach below provides another “layer of security”.
Even one or two of these items can often provide sufficient security for most assessments.

Proctors - Having students take an exam in a room being monitored by a proctor is a
major deterrent to most forms of cheating. Enhance this method by having the proctor
check the identification of the student prior to the start the exam, placing web cameras
throughout the room, or using a “quiz password” (see next item). For distance courses,
proctored settings can be established in other cities, even other countries. Because of
the time and expense required for a proctored setting, proctors are sometimes used only
with high-stake assessments (eg. midterms, finals).

Quiz Passwords (Desire2Learn setting) - A quiz password prevents students from
accessing the exam until a password has been supplied. Quiz passwords can be typed
by the proctors themselves (for added security) or conveyed to the student at the start of
the exam.

Attempts Allowed (Desire2Learn setting) - By only allowing one attempt for a quiz,
students won’t be able to determine the questions in the quiz, look up the answers at a
later time, and then retake the quiz.

Required to View Quiz Feedback and Results with Respondus LockDown Browser
(Desire2Learn Setting) – A quiz that requires the LockDown Browser to be used for
viewing feedback and results will prevent students from printing or copying questions
after the quiz has been delivered (ie. protecting the questions for future terms).

Randomize Options (Desire2Learn setting) - Answer choices to multiple choice
questions can easily be randomized. This setting is selected at the time a question is
created.

Question Randomization (Desire2Learn setting) - Question randomization ensures that
the question order is different for each student. To create a randomized quiz, you need
to build your questions in a section of the quiz library first, then create a random section
in your quiz, and draw the questions from the question library into the quiz.

IP Restriction (Desire2Learn setting) - If quizzes are being delivered from a central
location, the IP address (or a partial address) for those computers can be specified, thus
preventing access from other locations.

Time Limit (Desire2Learn setting) - By limiting the time a student can spend on an
assessment, students can be discouraged from consulting other sources since they
won’t have time to do so.

Availability Dates and Times (Desire2Learn setting) - This setting restricts the availability
of the quiz to a specific date/time range.

Code of Conduct - Have students sign an honesty statement that summarizes the
expectations and requirements for academic honesty.

Other methods of assessment - Combine objective tests with other methods of
assessment, such as group projects and writing assignments. Essay questions also
make it difficult for students to cheat on a traditional assessment, knowing that the
instructor may recognize an answer that has been copied from another student.
