Computerized (i.e. computer-based) testing offers not only a more efficient way of administering tests but also a more objective view of a students's level of language proficiency.

In my PhD thesis, I will evaluate tests of general language skills (C-Tests) and diagnostic tests of specific language skills (multiple choice tests) with a focus on computerized adaptive testing.

Computers have long found their way into the language classroom. Learners can improve their command of a foreign language by, for instance, using specialized software on CD-ROM or by exploring the Internet. Multimedia, hypertexts, the so-called "new technologies," etc. offer a rich and valuable "pool" of resources and teaching (or learning) materials. In addition to these classroom-based opportunities, computers can also be used as tool for linguistic and didactic research (e.g. "concordancers").

Generally speaking, I am interested improving the possibilities and in avoiding the pitfalls of CALL.

Computers can easily be used to facilitate interaction between learners without restrictions of time and space. Synchronous and asynchronous learning environments enable students to interact and collaborate in learner tandems or in small groups. For example, students from different countries can meet synchronously in a MOO, or they can exchange ideas asynchronously via e-mails or message boards.

Furthermore, computers and the Internet offer an almost uncountable number of ways of web-based or computer-based distance learning, for example for virtual classrooms, for blended learning scenarios, or for CD-ROM-based distance learning projects.

I am interested in improving and evaluating different ways and methods of distance learning with a special focus on synchronous learning environments (MOOs) and blended learning scenarios.
