Assessment methods and criteria: The object of assessment of students' knowledge is the program material of the discipline of various nature and level of complexity, the assimilation of which is checked accordingly during the current control and exam.
The task of current control is to check the understanding and assimilation of certain material, the developed skills of performing laboratory and practical seminar tasks, the ability to independently process texts, the ability to understand the content of a topic or section, the ability to publicly or in writing present certain material.
The task of the exam is to check the student's understanding of the program material as a whole, the logic and relationships between individual sections, the ability to creatively use the accumulated knowledge, the ability to form one's attitude to a certain problem of the educational discipline, etc.
The final (final) assessment of students' knowledge in the discipline "Technology of production and processing of polymers" is carried out, according to the procedure established by the Lviv Polytechnic University, on a 100-point scale, taking into account the results of the current and final control.
Критерії оцінювання результатів навчання: the general 100-point knowledge assessment scale is distributed as follows:
- assessment of current performance (practical classes): 10 points;
- assessment of final exam results: 90 points. (70 letters, 20 oral component)
Порядок та критерії виставляння балів та оцінок: 100–88 points – (“excellent”) is awarded for a high level of knowledge (some inaccuracies are allowed) of the educational material of the component contained in the main and additional recommended literary sources, the ability to analyze the phenomena being studied in their interrelationship and development, clearly, succinctly, logically, consistently answer the questions, the ability to apply theoretical provisions when solving practical problems; 87–71 points – (“good”) is awarded for a generally correct understanding of the educational material of the component, including calculations, reasoned answers to the questions posed, which, however, contain certain (insignificant) shortcomings, for the ability to apply theoretical provisions when solving practical tasks; 70 – 50 points – (“satisfactory”) awarded for weak knowledge of the component’s educational material, inaccurate or poorly reasoned answers, with a violation of the sequence of presentation, for weak application of theoretical provisions when solving practical problems; 49-26 points - ("not certified" with the possibility of retaking the semester control) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to apply theoretical provisions when solving practical problems; 25-00 points - ("unsatisfactory" with mandatory re-study) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to navigate when solving practical problems, ignorance of the main fundamental provisions.
