Digital testing environment

We offer a digital testing environment, based on the open source product TAO Testing, that can be used for both summative and formative testing. This testing environment supports only a limited number of question types. In June 2018, a successful digital test was performed with a Windows application (a modern computer program development environment) that ran in a tab of the exam browser and was delivered through Amazon Appstream 2.0. With this, many limits of TAO Testing can be circumvented.

In TAO itself, there is no support for entering mathematical or chemical formulae in answers, although formulae can be used in questions. Entering computer source code is possible in a free text field, but not in a manner which resembles the computer program development environments people are used to nowadays. So, in general, questions which require free text or multiple choice answers are currently supported in TAO iself. Images can be used in questions and it is possible to let the student make and upload a drawing (using a basic tool available on the desktop such as Windows Paint) as (part of) their answer.

The environment consists of four parts, all of which are web-based.

  3. A “testing” (exam) environment in which tests can be performed. The tests take place on the computer lab PCs managed by C&CZ in a so called Secure Exam Browser environment.

At this moment all four parts of the environment exist and are operational.

Advantages and disadvantages

The advantages of digital testing are many.

    2. Automatic grading of multiple-choice questions is possible.

There are also disadvantages:

  2. Digital testing places a burden on the available PCs for students. This problem increases as the use of digital testing grows. That's why Radoud University purchased more than 600 Chromebooks to be used for digital tests in e.g. a sports hall in the Gymnasium.
