Teaching Methodologies and Assessment Criteria |
The course unit consists of theoretical lectures and laboratory practicals. The teaching and learning methodology is student-centered. In the theoretical lectures, the instructor presents the course content, introducing examples and applications for discussion while encouraging reflection and problem-solving. Laboratory practicals take place in the Textile Chemistry Laboratory, where students can work with various machines and equipment and conduct several experimental projects in the field of textile chemistry.
At the end of each experiment, students must prepare a written report to apply their acquired knowledge and scientifically discuss the results. The course assessment consists of a written midterm exam (during the teaching period) with a 50% weighting, and continuous assessment of the Practical (P) component, also weighted at 50%.
