Teaching methods

The course is realized in laboratories. Students are doing simple experiments according to the instructions in the textbook.On the base of results they prepare the lab-reports.

Assessment methods

Conditions for giving credit:Full attendance in all lessons (making up all missing and justified lessons), completion of all lab reports and handing them to the teacher till given date.Twelve test are writen during the semester. Student will recieve course unit credit, if he has at least 70% of points. The other students will write the credit test.This test has 30 questions and student must obtain at least 12 points. The test can be once time repeated.

Language of instruction

Czech

Further comments (probably available only in Czech)

The course is taught annually.
