COURSE DESCRIPTION

Course objectives

Student will acquire proficiency in knowledge that allowed him to perform electrochemistry experiment and complete the research of mechanism and kinetics of electrode processes.

Course enrolment requirements and entry competences required for the course

 

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After the successfully passed exam student is able to:
- explain the mechanism and kinetics of electrode processes
- properly choose the experimental method of measurement
- carry out electrochemical experiment independently
- analyze the experimental results
- predict the behavior of metallic materials under different conditions.

Grading and evaluating student work in class and at the final exam

The complete exam can be passed through two tests during semester. The passing score is 60 % and the fraction of each test is 40 %. The fraction of laboratory exercises is 20%. In the exam period the student has to attend to written and oral exam. Grades: <60% insufficient, 60-70% sufficient, 71-80% good, 81-92% very good, 93-100% excellent.

Quality assurance methods that ensure the acquisition of exit competences

- monitoring of students suggestions and reactions during semester
- students evaluation organized by University
Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
