ECDL Testing System

Nowadays computer-based testing is used for testing knowledge in various areas. Initially simple computer-based tests of fixed length were used. Later on, as there arose the need for security of questions and more effective assessment of test takers‘ knowledge and individual generation of questions, computer-based testing was improved looking for solutions to arising problems. As a consequence, several questions design methods were developed. Even in educational institutions some exams are being replaced by tests. Therefore, such testing should be done qualitatively. Qualitative testing is especially important in specialized testing systems, such as testing people‘s digital literacy knowledge’.

Currently in Lithuania ECDL tests can be taken using automated testing system, which is installed on ITI server www.ecdl.lt. Testing system has been designed according to traditional IS design methods and works steady. This testing system is authorized by ECDL Foundation and is competitive with other commercial products. Lithuanian ECDL testing system is multilingual: tests can be taken in Lithuanian, Russian and Latvian languages. The interface of the testing system is translated to these languages too.

In Lithuanian testing system for ECDL tests questions are delivered sequentially. The test is formed from 36 questions. Skipped questions in the test can not be revised later. When the test is finished, the state of passing/failing the test is shown. There is no skill level assigned to users depending on earlier tests results. The ECDL test questions can be of four types:

  • Multiple choice with four answers, where only one answer is correct. However creating these questions can take much time, because creating incorrect answers can be difficult. The probability of the student guessing is relatively low.
  • Multiple choice with image and four answers, where only one answer is correct and others incorrect. In this case image visually shows essence of question and in such way it is easier for test-taker to comprehend the question.
  • True/false questions. In this case test-taker gets the statement and must decide if this statement is right. This type of question is easy to create, but the test-taker has relatively high probability of guessing (50%).
  • Hotspot questions. In this case test-taker must click on a picture in order to answer a question. Usually the picture has several correct and incorrect answers. This type of question is designed for assessment of practical skills.
