BEGINNER (CEFR Level A1 - Breakthrough) LEVEL is in the group of Basic User. At the end of this level, those who are successful will understand and use familiar everyday expressions and very basic phrases aimed at the satisfaction of needs of a concrete type; will introduce him/herself and others and can ask and answer questions about personal details such as where he/she lives, people he/she knows and things he/she has; will interact in a simple way provided the other person talks slowly and clearly and is prepared to help.

ELEMENTARY (CEFR Level A2 - Waystage) LEVEL is in the group of Basic User. At the end of this level, those who are successful will understand sentences and frequently used expressions related to areas of most immediate relevance (e.g. very basic personal and family information, shopping, local geography, employment); will communicate in simple and routine tasks requiring a simple and direct exchange of information on familiar and routine matters; will describe in simple terms aspects of his/her background, immediate environment and matters in areas of immediate need.

PRE-INTERMEDIATE (CEFR Level A2+) LEVEL represents a strong Waystage performance. At the end of this level, those who are successful will understand sentences and frequently used expressions related to areas of most immediate relevance (e.g. very basic personal and family information, shopping, local geography, employment); will communicate in simple and routine tasks requiring a simple and direct exchange of information on familiar and routine matters; will describe in simple terms aspects of his/her background, immediate environment and matters in areas of immediate need.

INTERMEDIATE (CEFR Level B1 – Threshold) LEVEL is in the group of Independent User. At the end of this level, those who are successful will understand the main points of clear standard input on familiar matters regularly encountered in work, school, leisure, etc.; will deal with most situations likely to arise whilst travelling in an area where the language is spoken; produce simple connected text on topics which are familiar or of personal interest; will describe experiences and events, dreams, hopes and ambitions and briefly give reasons and explanations for opinions and plans.

INTERMEDIATE PLUS (CEFR Level B1+ - Strong Threshold) LEVEL is in the group of Independent User. At the end of this level, those who are successful will understand the main points of clear standard input on familiar matters regularly encountered in work, school, leisure, etc.; will deal with most situations likely to arise whilst travelling in an area where the language is spoken; produce simple connected text on topics which are familiar or of personal interest; will describe experiences and events, dreams, hopes and ambitions and briefly give reasons and explanations for opinions and plans.

UPPER-INTERMEDIATE (CEFR Level B2 - Vantage) LEVEL is in the group of Independent User. At the end of this level, those who are successful will understand the main ideas of complex text on both concrete and abstract topics, including technical discussions in his/her field of specialisation; will interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain for either party; will produce clear, detailed text on a wide range of subjects and explain a viewpoint on a topical issue giving the advantages and disadvantages of various options.

ADVANCED (CEFR Level C1 – Effective Operational) LEVEL is in the group of Proficient User. At the end of this level, those who are successful will understand a wide range of demanding, longer texts, and recognise implicit meaning; will express him/herself fluently and spontaneously without much obvious searching for expressions; will use language flexibly and effectively for social, academic and professional purposes; will produce clear, well-structured, detailed text on complex subjects, showing controlled use of organisational patterns, connectors and cohesive devices.

This course will follow three main paths: Firstly it will introduce philosophy to doctoral students. The meaning of philosophy, its scope, its sub-branches and its different schools will be the subject topic of the first weeks. Then the course will focus on the relation of philosophy with the sources of knowledge and different sciences. Here, Rationalism, Empiricism and Intuitionism will be covered during the following weeks. In the remaining weeks the course will concentrate on philosophy of science and scientific ethics. Logical positivism, paradigm changes, falsificationism, the questions of “what is science”, “what is pseudo-science?”, “what is the relation between theory and reality?” are amongst topics that will be covered. Finally, the course will concentrate on ethical theories and will particularly cover scientific ethics.
