Prezenţa şi pregătirea pentru cursuri Prezenţa la cursuri este o condiţie esenţială a bunei desfăşurări a întregii activităţi educaţionale. Participarea studenţilor este necesară întrucât o audiere directă îi ajută la o mai bună înţelegere a noţiunilor predate, la folosirea unui vocabular adecvat, le crează posibilitatea întreţinerii unui dialog interactiv precum şi a unei integrări în disciplina universitară. Lecture Preparation and Attendance The course attendance is a necessary condition of a good evolution of whole training process. The students attendance is necessary as a direct hearing helps to understand better the topics, to use an adequate vocabulary as well as creating the possibility of keeping an interactive dialogue and of integrating in academic discipline. Asistenţă în pregătirea examenelor Pentru o bună înţelegere a materiei predate şi pentru o implicare în învăţarea treptată a acestei materii, studenţii sunt supuşi unor teste periodice în timpul semestrului. Li se acorda consultaţii de către cadrele didactice care efectuează orele. Study Coaching For a better understanding of topics and for an involvement in graduated study of this discipline, the students are periodically tested during the semester. They can participate in tutorials given by academic staff responsible of this course. Conţinutul Activităţii aplicative Nr. lab.
