Course abstract

„Chemistry” program focuses on generality of the chemical elements and compounds, transformations and properties of inorganic compounds. Introduction to organic chemistry. The structure, classification, isomerism of organic compounds, type of reactions. Chemistry of polymers is related to physical-chemical properties of polymers used in constructions, decoration materials, binding agents and adhesives. To improve knowledge and skills training materials, individual work-tasks and laboratory works which illustrate the importance of chemistry in ones field are provided.

Learning outcomes and their assessment

After completing the course student will have: knowledge and understanding of compounds, their properties, generality of transformations and practical significance – lectures and tests; knowledge basis to help in further studies and self-perfection; skills to think analytically and be creative to apply in practice generality of chemistry in both studies and ones professional work – laboratory works and its reports; competence to acquire, select and evaluate new information in an equitable fashion independently and use it to solve issues related to use of chemical compounds – reports of laboratory works.

Requirements for awarding credit points

To receive a course grade, students must perform the following criteria:
• Students must perform all laboratory works and submit laboratory reports;
• Students must write all tests during the semester (at least 4) and complete exam (at least 4).
If the average mark in the tests is not less than 7 and no more than two tests are overwritten, the exam may not be taken.

Description of the organization and tasks of students’ independent work

Preparing for test and practical works. Reading scientific literature, analysing results of experiments.

Criteria for Evaluating Learning Outcomes

The final grade of the study course is calculated using a marking scheme:
•tests (80%);
•reports of laboratory works (20%);
All laboratory work must be inducted and included in laboratory work protocols. Each of the above course activities forms a certain percentage of the total mark.
The student must obtain a successful assessment (at least 4 points) for each course activity (tests and homework). The course is completed if all the above conditions are met.
