Assesment methods and criteria linked to learning outcomes
Evaluation is based on oral presentation and written exam. The presentation should report on selected topics from applied colloid chemistry in about 10 minutes, clearly presenting and emphasizing specific colloidal aspects and consequences of the selected topic. The aim of the presentation is to demonstrate student's ability to see and explain colloidal essence of the selected topic not just refer on the topic. The presentation is followed by discussion (5 minutes) which can include also theoretical principles of presented topic. The presentation should be sent to the teacher electronically. The subject and its elaboration can be consulted with teacher and finally is presented during lectures. Suitable examples of presentation topics are given during the first lecture. The written exam consists of ten questions which should be answered in one phrase each and within the time limit of 50 min in total. Both parts has the same weight; in evaluation of presentations the technical quality has the weight 70% and the presentation quality 30%.
