Test vs. Teacher
Резюме. The basic figure in school is the teacher. The teacher is responsible for the realization of the educational goals and the different learning/teaching methods combined with the new information-communication technologies are his/her tools in this direction. Undoubtedly the summative tests are proper instruments for an assessment of the pupils’ achievements. However they will be of use if their results are an object of careful discussion between the teacher and his/her students. The final responsibility for pupils’ assessment should belong to the teacher rather than to the machine. This assessment should have a complex character taking into account the overall teaching process in the school years rather than to emphasizing on incidental test records.

Multimedia Modules: Chemical Bonds
Резюме. A Web-based multimedia product about chemical bonding has been developed. It consists of three components: Covalent Bond, Ionic Bond and Metallic Bond that are designed in similar manner: a tutorial section to support students learning with basic facts and information, and a test section to help learning the new concepts. Three-dimensional dynamic models and animated images visualize the formation of chemical bonds. The knowledge structure matches both the chemistry curricular contents of the foreign students’ preparatory course and the Bulgarian Secondary School. So the product can be used by these categories of students at school or at home.
