Student Assessment
Description
Students are evaluated with a written exam, covering the spectrum of the course field. The critical thinking, as well as the level of understanding the course are examined by theoretical questions, multiple choice and exercises in a percentile proportion of approx. 20, 20, 20%, respectively. The rest 40% concerns the evaluation of the laboratory performance of students. Among the evaluation criteria are included the participation in the labs, the quality of the produced results, as well as the quality and soundness of the technical report.
Student Assessment methods
  • Written Exam with Multiple Choice Questions (Formative, Summative)
  • Written Exam with Short Answer Questions (Formative, Summative)
  • Written Assignment (Formative, Summative)
  • Labortatory Assignment (Formative, Summative)
