Multilingual graphical authoring editor in a Distributed e-Testing

This paper describes a multilingual graphic editor for creation of circuits, drafts and graphics in such subject areas where it is possible to pre-define the composite graphic elements. The database with testing questions stores only the indices of the composite graphic elements, their coordinates, size and the connections among them. As a result we have a substantial decrease of the size of the database, the data transferred to the learners and, consequently, the time required for visualization of the testing questions on-line. Another important contribution is the opportunities to dynamically generate circuits, drafts and graphics in a number of cases, thus decreasing the number of questions, authored in advance. The graphic editor is developed as an extension to the Dynamic Test Development Tool in Distributed e-Testing Cluster. It is multilingual, i.e. all the elements of the user interface (menus and buttons) are parameterized, with the actual texts of the supported languages stored in the database. 1
