CADE Off-Air Testing
At the end of a broadcast it is still possible to interact with the
participants at the remote locations through the off-air testing feature of
CADE. This feature will allow participants to take a test of any number of
questions using their wireless remote controls. While participants can no
longer see the facilitator or instructor, they are still connected to the studio
via the IP connection. The following information is provided to illustrate
how off-air testing is done.
Starting an Off-Air Exam
After the questions during the session have been issued, any test
(off-air exam) associated with the course will be displayed. A
program can have any number of such exams.
When the test is started, a timer begins a countdown on both the Studio
Control and Virtual Classroom screens. This time value comes from
the test length field in the Test master record in the database and is
managed with the Learning Management Web.
Virtual Classroom Display
On the Virtual Classroom display, the timer is large enough so you can
see the countdown timer, and how much time is left, from your workspace in
Each student may answer each question on the test independently from
all others. Student responses during an exam can not be seen on the
screen, only the individual's wireless remote control.
Plus and Minus buttons on the screen or Forward and Back buttons on the
remote allow students to move forward and back using either the wireless
remote control or the mouse.
During the test, studio personnel can monitor progress from the Studio
Since the progress will typically be monitored periodically, the
progress values are updated on demand as required. This also helps
to reduce the demand on database, communication, and computing resources
during the testing process.
Studio personnel can retrieve results any time by clicking the
"Get Totals" button. This will take a snapshot of the
testing activity at that point in time and displays progress for both
student and site.
Each student's percent of questions complete is displayed adjacent to
their name. The overall percentage for the students at a specific
location located before the site name.
Monitoring a Specific Site and
If you click on a site, you will be shown all the people at that site
and how far they have progressed in the test.
You can use text chat with a single site by selecting their site name
in the chat window and sending them a message.
No one needs to be at the remote computer to receive your
message. The system uses text-to-speech generation so anyone in the
room will hear your message... albeit in a computer generated voice.
Course Scheduling and Studio Identification
Scheduling can be done by authorized personnel anywhere they have
access to the network. While courses do not have to be scheduled,
there are a number of advantages to doing so.
When scheduling a course for broadcast, the studio location can be
specified in the scheduling form. This will cause the system to
check for scheduling conflicts or overlaps in the desired studio.
Identifying a studio location during scheduling also allows the Virtual
Classrooms to automatically link to the proper studio should there be
concurrent broadcast sessions at the time they were logging
When a Virtual Classroom starts, the CADE system checks to see if
anyone at that site is registered in a course that's about to start or is
currently underway. If they are, the Virtual Classroom will link to
the appropriate studio. If no students are registered, the currently
on-air courses will be displayed on the Virtual Classroom screen so they
can choose which course to join.
Text-To-Speech Communication with All Sites
Likewise, you can open the group chat window and communicate with
everyone in the broadcast. The system uses the text-to-speech capability as well so you can announce the
test is almost over or any other appropriate message you would like the
students to hear while they are completing their test.
