The lectures are supplemented by computational exercises, computer simulations labs, and measurements testing of individual electrical machines, their electronics and PLCs.
    10. Assessment

    The assessment of learning outcomes is based on two mid-year written summative academic performance assessments (midterm exams) and one partial performance assessment (homework).

    • summative academic performance assessment (midterm examination): a complex, written assessment method of the subject, knowledge, and skills-type competence elements in the form of a midterm exam, which basically focuses on the application of acquired knowledge, thus placing problem recognition and solution at the center, i.e. practical (calculation) tasks must be solved during the performance assessment. The part of the curriculum, serving as the basis for the assessment, is determined by the subject lecturer in agreement with the practice supervisors, the available working time is 90 minutes;
    • partial performance assessment (homework): a complex method of assessing the knowledge, skills, attitude, and autonomy and responsibility-type competence elements in the the form of individually prepared homework, the content, requirements, submission deadline and assessment method of the homework are determined by the practice supervisor;

    "+" means that with diligent tasks, a value greater than 100% can be achieved. 

     

    Conditions for accepting the midterm exam: The combined score of the first and second midterm exam must reach 40% of the total score, i.e. 32 points. The minimum score for the accepted homework: 8 points - i.e. also 40% of the maximum 20 points.

    All laboratory measurements must be completed. A maximum of 2 measurements can be retaken. 

     

    Determination of grades 

    grade ● [ECTS qualification]

    score

    excellent(5) ● Excellent [A]

    Above 90%

    excellent(5) ● Very Good [B]

    85–90%

    good(4) ● Good [C]

    70–85%

    medium(3) ● Satisfactory [D]

    55–70%

    sufficient(2) ● Pass [E]

    40–55%

    insufficient(1) ● Fail [F]

    Below 40%

    The lower limit value specified for each grade already belongs to the given grade.

    11. Recaps
    1. There is no individual minimum requirement for each mid-year performance evaluation, therefore it is not possible to retake them individually.
    2. Homework can be submitted late until the end of the late completion period, subject to payment of a fee specified in the regulations.
    3. The two midterm exams can be retaken or corrected in a combined form during the late completion period - for the first time - free of charge. In the case of correction, the more favorable result for the student will be taken into account between the previous and the new result.
    4. If the student is unable to obtain a grade other than fail, even with the retake as per point 3), he/she may make a second attempt in a consolidated form, to correct the unsuccessful first retake, in addition to paying the fee specified in the regulations.
    12. Consultations

    At time agreed in advance with the lecturer or the practice supervisors.
