Assessment Methods
The scores of the course are arranged as follows: 1
Attendance at the classes
Attendance at the classes For class attendance , the scores of the students are dependent on the discussion in the class and the exercises in the class. The criteria we will take for the evaluations of class attendance are as follows: (1) Did the students listen to the lectures carefully? (2) Did the students state the points correctly and concisely? (3) Are the points stated by the students related with the contents of the course ? Did the students use theoretical knowledge supporting their points? Homeworks: The homeworks will be arranged after the classes, and the evaluation of the homeworks will depend on the quality of the home work, i.e. if the answers are correct, and if the students do the home work carefully.
