Goal

• to provide basic information on measurement methods and to familiarize with modern means of automatic control of the most important technological variables of processes in industry.

Objective

• To acquire the skills of choosing rational measuring instruments, organizing their trouble-free operation

Learning outcome: knowledge and understanding

• knowledge of the basic provisions of measurement theory, principles of construction of measuring devices, methods of solving problems of adaptation to changes in measurement conditions, types and characteristics of the main measuring transducers

Learning outcome: applying knowledge and understanding

• Ability to use the basic techniques of experimental data processing, present the results to the consumer, implement a flexible measurement strategy

Learning outcome: formation of judgments

• The ability to independently apply methods and means of cognition, learning and self-control, to realize the prospects of intellectual, cultural, moral, physical and professional self-development and self-improvement, to be able to critically assess their strengths and weaknesses.

Learning outcome: communicative abilities

• The ability to work effectively individually and as a team member, demonstrating leadership skills of individual groups of performers, including on interdisciplinary projects, be able to show personal responsibility, commitment to professional ethics and standards of professional activity.

Learning outcome: learning skills or learning abilities

• To carry out communications in the professional environment and in society as a whole, including in a foreign language.

Teaching methods

During the training sessions, the use of the following educational technologies is provided: - interactive lecture (the use of the following active forms of learning: guided (guided) discussion or conversation; moderation; demonstration of slides or educational films; brainstorming; motivational speech); - creation of scenarios for the development of various situations based on specified conditions; - information and communication (for example, classes in a computer classroom using professional application software packages); - search and research (independent research activity of students in the learning process); - solving educational tasks.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Period	Type of task	Total
1  rating	Practice 1	0-100
	Practice 2
	Boundary control 1
2  rating	Practice 3	0-100
	Practice 4
	Boundary control 2
Total control	Exam	0-100

The evaluating policy of learning outcomes by work type

Type of task	90-100	70-89	50-69	0-49
	Excellent	Good	Satisfactory	Unsatisfactory

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

FG = 0,6	MT1+MT2	+0,4E
	2

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:

Alphabetical grade	Numerical value	Points (%)	Traditional grade
A	4.0	95-100	Excellent
A-	3.67	90-94
B+	3.33	85-89	Good
B	3.0	80-84
B-	2.67	75-79
C+	2.33	70-74
C	2.0	65-69	Satisfactory
C-	1.67	60-64
D+	1.33	55-59
D	1.0	50-54
FX	0.5	25-49	Unsatisfactory
F	0	0-24
