Joint activity means that each student makes his own individual contribution, in the course of the work there is an exchange of knowledge, ideas, methods of activity. Organized individual, steam and group work. Interactive methods are based on the principles of interaction, activity of trainees, reliance on group experience, mandatory feedback 11 Language Russian 12 Conditions (requirements), current control – test; – colloquium The score on the exam is set taking into account: The score on the exam is set taking into account: 30% – work in laboratory and practical classes, 70% – oral examination. 13 Appraisal Form examination
