APPLYING RESEARCH BOOK FOUR is designed to help students to enhance their capacity to detect a problem or doubt that can be tackled with research techniques; to be able to choose and limit a topic; to formulate hypothesis or to define objectives properly and to be able to apply the best criteria when choosing research techniques according to the subject. Communication techniques are underlined to encourage students to express themselves coherently in diverse situations, both in study and social environments. Students are expected to complete the research cycle, with sufficient practical experience to be able to carry out a bibliographical research independently with minor tutoring, being thus able to collect information, process it systematically and prepare and deliver a correct oral or written report.
