This paper presents the work of creating a support online course using Adobe Flash technology and Action Script 3. The application created uses several techniques of presenting educational material, namely: plain text, like power point presentation, making videos with Camtasia Studio application. For checking the knoledge acquired by students, we used two sets of tests. The first is a fixed set of tests, the questions with a single correct answer, multiple correct answers with text input with choosing an image and using drag and drop. The second set of tests is to display random questions taken from a xml file. The result of work is a very useful educational environment through: the small size of the written code, by the portability and the ease of maintenance and updating. Portability is assured by the flash technology that by the flash player which is available for free on almost any operating system, allows use material support developed on almost any computer.
