Examination equipment, rooms and set-up
The project’s mobile test center provides 100 laptops and 200 tablets for e-examination with the following specifications:
|Type||Dell Latitude 3300||iPad 9,7 (Wi-Fi, 2018)|
|Processor||Intel i5-8250U||Apple A10 Fusion|
|RAM||8 GB DDR4||2 GB|
|Hard disk||256 GB SSD||32 GB|
|Screen||13.3 inch, 1920x1080, Touch||9.7 inch, 2048x1536, Touch|
|Operating system||Windows 10||iOS 11|
The laptops are also equipped with privacy filters, which prevent possible attempts at deception. RStudio (open source) and the Safe Exam Browsers (open source) have already been used as exam software on the test center’s laptops. On the laptops in the room K1520 (see below), MATLAB (license software) has been used in e-exams as well.
The structure used there so far is as follows. The test center is integrated into the university's network infrastructure via LAN.
- The test center server serves as DHCP server and domain controller,
- is connected via a fixed switch to an examination server of the TUHH, and
- connected to laptops of the test center via portable switches.
Network topology (LAN)
A second setup variant in the rooms D2.022, D1.023, H0.09 and Audimax 1, for which tests are currently underway, is a variant in which the test center operates in its own WLAN and is connected to the university's network infrastructure via the test center server, which also allows the use of tablets.
Network topology (WLAN, dependent)
In this third variant, which has so far only been successfully implemented at the UKE using tablets, the test center is independent of the institution's network infrastructure.
- The test center server serves as DHCP, exam server and domain controller,
- is connected to wireless access points (WAPs) via a portable switch,
- which are managed by a WAP controller and
- are connected to tablets via WLAN.
Network topology (WLAN, independent)
For smaller e-exams with up to 30 participants (per examination slot) laptops of the ZLL are also available in the room K1520. Depending on the examination software (No Safe Exam Browser usable!), computer pools may also come into consideration.
