Teaching methods

FIRST and SECOND MODULE
The present course is realized with frontal lessons (both theory and exercises) via IN-PRESENCE. In particular, the teacher takes lessons in the classroom with the help of PC (Powerpoint slides) and board (via graphic table connected to the PC); the
lesson slides are uploaded in Elly.
The teacher also performs exercises (in classroom with the collaboration of students) in order for the student to: 1) apply the theory to solve practical problems dealing with the contents of the course; 2) verify learning before passing to the subsequent subject; 3) get a method for the execution of exercises in both retrosynthesis (disconnection of a target molecule) and synthesis (preparation of a target molecule) directions.
The student is expected to read and study the contents of the lessons by him/herself by using notes/slides and textbook, and applying this knowledge in the execution of exercises, including 1) the exercises made in classroom, 2) exercises in the textbook and study guides, and 3) exercises assigned during lessons and loaded weekly on the Elly platform. Solutions of exercises are subsequently given by the teacher, for self-evaluation of the students. In addition, many copies of the text of written examinations of the past academic years are loaded and updated in the Elly platform (with solutions), to provide further tools in the preparation of the examination. The teacher is available for further explanations about theory and exercises in the following moments: 1) at the end or during the break of the lesson, 2) in office or by distance via Teams.

Assessment methods and criteria

1° and 2° MODULE
To verify the level of knowledge and learning of the student, a written test for each module is mandatory (1 hour-long for Chimica Organica Propedeutica, COP, and 2 hours for Chimica Organica, CO) consisting of 7/8 (COP) or 4/5 (for CO) open-answer questions having different weight and corresponding to a score detailed in the text. The result is marked in thirtieth, with a minimum pass of 18; each test contributes for the 45% of the final quotation of the whole examination. To access each of the written exams, the student must register on-line (via Essetre) in the dates according to the official exam schedule of the Food and Drug Department. In addition, students have the possibility to carry out the COP written test “in itinere” (in November) and, if successful, they will be allowed to access to the second test (CO) without repeating the first one. The partial test of COP has a validity of about 6 months, period along which the student must carry out the second written test and the final oral exam. To access the final oral exam and subsequent recording, it is necessary to pass both written tests of the two modules. It is possible to carry out both tests in the same date since they are given at different times. To access the oral exam, the student may register via Essetre, but it is not mandatory.
Both written and oral exams are carried out IN PRESENCE.

During the written exams, no books, notes, nor web-related material are permitted; possible compensatory material will be allowed to students with DSA or BES, which will be agreed upon with the teacher at least one week before the exam.
The written test of COP is judged positive (superior or equal to 18/30) when the student demonstrates knowledge and learning of the nomenclature of basic organic molecules, acid-base reactions, writing the structure of simple organic molecules including different conformations and configurations. The laude (30/30 cum laude) is assigned as a maximum quotation when all questions are correctly answered and when specialized language is used.
The written exam of CO is judged positive (superior or equal to 18/30) when the student demonstrates knowledge and learning of the following contents: identification and knowledge of the functional groups (as detailed in the contents) within natural or drug -ike polyfunctional molecules; identification of carbon stereocenters and chirality; knowledge of the main aromatic and heteroaromatic cyclic compounds with the corresponding resonance structures; execution (even partial) of exercises on synthesis sequences and interconversion of functional groups; execution (even partial) of exercises on the total synthesis of simple organic compounds. The laude (30/30 cum laude) is assigned as a maximum quotation when all questions are correctly answered and when specialized language is used. The result of each written examination is given within one week from the date of the same exam and anyway before the date of the oral exam of the same session via Essetre portal.
The final oral exam (10-20 min, 10% of the overall quotation) deals with a brief discussion of the subjects of both modules.
