Student Assessment
Description
At the beginning of the semester, a series of mandatory introductory lectures is conducted. Following this, students are offered the following options for assessment:
a) Writing a research paper based on data collection, with a presentation at the end of the semester
b) Writing a literature review paper, also with a presentation at the end of the semester
c) Participation in a written or oral exam with open-ended questions.
Choosing the examination option (written or oral) does not entail a reduced workload. Students who select this form of assessment are required to actively participate in the semester’s teaching activities (e.g., exercises, additional lectures), in order to ensure equivalence in learning outcomes compared to options (a) and (b).
Student Assessment methods
- Written Exam with Short Answer Questions (Summative)
- Written Assignment (Summative)
- Oral Exams (Formative)
- Performance / Staging (Summative)
