Optional projects given to students to solve sophisticated problems using computer programs’. All presentations are accessible by the students in the e-class platform together with solved problems.

In Labs: There is a portal in e-Class for submission, correction and marking of laboratory reports. Furthermore, the book with the theoretical analysis of each exercise for the preparation of the students before the exercise, together with the leaflet for the completion of the lab report can also be found there.

TEACHING METHODS

The manner and methods of teaching are described in detail.

Lectures, seminars, laboratory practice, fieldwork, study and analysis of bibliography, tutorials, placements, clinical practice, art workshop, interactive teaching, educational visits, project, essay writing, artistic creativity, etc.

STUDENT PERFORMANCE EVALUATION

Description of the evaluation procedure

Language of evaluation, methods of evaluation, summative or conclusive, multiple choice questionnaires, short-answer questions, open-ended questions, problem solving, written work, essay/report, oral examination, public presentation, laboratory work, clinical examination of patient, art interpretation, other

Specifically-defined evaluation criteria are given, and if and where they are accessible to students.

Greek language is used in the examination procedure. Examinations may be given in English in case of foreign students attended the course.

In lectures: Exams are written and include theoretical questions which are answering without further help and problems to be solved by using the book of the course. Marks are given to each and every question in order to achieve precise comparative evaluation between students.

In Labs: Assessment takes place with four means:

1)      Short written questionnaire (test) before each actual laboratory exercise takes place, about the basic concepts involved.

2)      Oral questions assessing the comprehension of each part of the exercise.

3)      Correction and marking of written reports submitted within a few days after the lab exercise is completed.

4)      Combinatorial questions from all laboratory exercises at the end of the semester, in the framework of a final, revision, lab exercise.
