The student publishes opinions and views without offending others.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, the student works with fellow students to solve tasks. With the student's knowledge, makes a responsible, informed decision based on analyzes. The student feels responsible for energy, the problems of energy management, and the sustainable use of the environment, as well as present and future generations. The student is committed to the principles and methods of systematic thinking and problem solving.
The methodology of the course consists of independent learning, teaching from lectures, and laboratory exercises. The lectures discuss the content of the educational material which is to be learned independently and in advance of the lectures. On these occasions, there is an opportunity to discuss self-acquired material, supplemented by additional materials and summaries presented with frontal educational techniques. The application and skill-level acquisition of knowledge takes place in laboratory exercises.

Validity of the course description
|Start of validity:||2020. March 3.|

Learning outcomes are assessed on the basis of a mid-semester written and oral summary performance assessment and a partial performance assessment. The summarizing academic performance assessment is a complex, written method of assessing the knowledge and ability type competence elements of the subject in the form of a written exam, while the oral assessment method is the elaboration and description of pre-defined items. These summative academic performance assessments require the required lexical knowledge to be taken into account during performance assessment. Partial performance evaluation is a complex way of evaluating the knowledge, ability, attitude, and autonomy, and responsibility type competence elements of the subject, the form of which is the group-based laboratory measurement and its report.
Detailed description of mid-term assessments
|Mid-term assessment No. 1|
|Purpose, description:||Summative assessments collectively examine and assess student's learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge and the existence of knowledge, and the application of skills gained in lectures and laboratory practice. The written summary assessment focuses 85% on theoretical knowledge and 15% on application skills. These will be completed on the dates specified in the academic performance assessment plan, expected to be the 14th week of the semester. Therefore, 45 points can be obtained on the written summary performance evaluation. A minimum of 40% needs to be achieved.|
|Mid-term assessment No. 2|
|Purpose, description:||Summative assessments collectively examine and assess student's learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge and the existence of knowledge, and the application of skills gained in lectures and laboratory practice. The oral summative assessment focuses 85% on theoretical knowledge and 15% on application skills. They will be completed on the dates specified in the academic performance assessment plan, expected to be the 14th week of the semester. 45 points can be obtained on the oral summary performance evaluation. A minimum of 40% is to be achieved.|
|Mid-term assessment No. 3|
|Type:||formative assessment, simple|
|Purpose, description:||Partial performance assessments collectively examine and assess student's learning outcomes determined by the knowledge and ability type of competencies applied. Accordingly, each sub-performance assessment assesses the existence of knowledge and the application of skills gained in laboratory practices. Partial performance assessments focus 15% on theoretical knowledge and 85% on application skills. For their fulfillment, active participation in laboratory sessions and a minimum level on laboratory reports is required. As a result, 10 points can be obtained on the written partial performance evaluations (reports). A minimum of 40% is to be achieved.|
