Teaching method
Teaching is conducted through theoretical-practical and practical classes.
The theoretical-practical classes are held in person, where the material is presented, and theoretical-practical problems are solved, either in teams or individually.
The practical classes are also conducted in person. Students are grouped into teams of 3 to 4 members and carry out two studies:
(1) Writing an abstract and giving an oral presentation on a topic chosen from websites (e.g. http://www.epa.gov/greenchemistry/pubs/pgcc/past.html), describing its compliance with the principles of Green Chemistry/Sustainable Engineering;
(2) Conducting a Life Cycle Assessment study of a product using the openLCA software (Greendelta), writing the corresponding report, and giving an oral presentation of the results obtained.
Evaluation method
1. Final rating scale in the TLQV course:
0 to 20 points
2. Rating scale for the Theoretical-Practical component (TP):
0 to 20 points
3. Rating scale for the Practical component (P):
0 to 20 points
4. Weights of the TP and P components in the final rating of the TLQV course:
Theoretical-practical rating: 50%
Practical rating: 50%
5. Evaluation in the P component:
5.1. Two reports (Practical Work 1 and Practical Work 2) presented by students in teams of 3 or 4 members (P teams).
5.2. Size of P teams: 3 or 4 members, but it may be necessary to adapt the size of P teams based on student withdrawals at the beginning or during the semester or the appearance of new students in the first weeks of classes.
5.3. Contents of Practical Works:
5.3.1. Practical Assignment 1: Writing and oral presentation of an abstract on a case study chosen from suggested websites, such as: http://www.epa.gov/greenchemistry/pubs/pgcc/past.html
Objective: Describe compliance with Green Chemistry/Sustainable Engineering principles, and calculate Green Chemistry Metrics.
5.3.2. Practical Assignment 2: Conducting a written report on Life Cycle Assessment using specialized software (openLCA) and oral presentation of the work.
Objective: Understand and use the Life Cycle Analysis methodology. Know how to use the openLCA software.
5.3.3. The submission dates for Practical Assignments 1 and 2 are communicated through the course Work Program and during the first practical classes that will initiate each assignment.
5.3.4. Method of Submission for Practical Assignments 1 and 2: The reports for Practical Assignments 1 and 2 are submitted through the course webpage on Moodle@FCT.
5.3.5. Decimal places:
Grade of the oral presentation of Practical Assignment 1 - No decimal places
Grade of the oral presentation of Practical Assignment 2 - No decimal places
Grade of the report of Practical Assignment 2 - With two decimal places
Practical final grade - One decimal place
5.4. Grading in the practical component: 0.40 * grade of Practical Assignment 1 + 0.60 * (0.40 * oral presentation of Practical Assignment 2 + 0.60 * grade of report of Practical Assignment 2)
6. Evaluation of the TP component:
6.1. The evaluation elements include an Open Question, a summative Test, and 4 Debates.
6.2. Open Question: The Open Question is made available on the course webpage in Moodle@FCT, up to one week before the date of the summative Test, and must be submitted on the course webpage in Moodle@FCT by 8:00 pm on the day before the Test.
6.3. Rating scale for the Open Question: 1 to 10 points.
6.4. Summative Test: The summative test is in-person and covers all the material taught in the TP and P components. The summative test includes calculation questions and multiple-choice questions. Scientific calculators are allowed. GRAPHIC CALCULATORS ARE NOT ALLOWED.
6.5. Date of the summative test: The date of the summative Test is defined in the test dates, as mentioned in CLIP.
6.6. Rating scale for the Summative Test: 1 to 10 points.
6.7. Debates in the TP component: 4 "Pros and Cons" debates are conducted between TP teams, with 4 or 5 students (depending on the total number of students enrolled in the course and attending the P classes), selected by the teaching staff of the discipline, grouping students from different P teams.
6.8. Debate Dates: The Debates are held on dates specified in the annual Working Program (please, refer to the Working Program of this school year).
6.9. Topics to be addressed in each of the Debates: Catalysis, Solvents, Biorefineries, and Carbon Capture, Storage, and Use.
6.10. Ratings in the Debates: Each debate will have a winning TP team, determined by student votes who attend the Debates (50% for the final decision of the winning team) and Professors who attend the Debates (50% for the final decision of the winning team). Students in the winning teams in TWO DEBATES will receive a bonus of 0.5 points added to their theoretical-practical rating.
6.11. Attendance in the Debates: Attendance in the Debates is MANDATORY. The absence of Debates results in a -1.0 point penalty in the TP grade.
6.12. Additional events in the TP classes: Additional assessment events may occur in the theoretical-practical classes, up to +0.2 points per event, such as presenting questions to the teams participating in the Debates.
6.13. Decimal Places:
Classification in Debates - One decimal place
Classification in the Open Question - One decimal place
Classification in the summative Test - One decimal place
Bonuses for additional activities in TP classes - One decimal place
Final theoretical-practical classification - One decimal place
6.14. Rating in the theoretical-practical component: 1 to 10 points for the Open Question + 1 to 10 points for the summative Test + Bonuses for winning a Debate + Bonuses for additional activities in the TP classes - 1 point penalty for absence in Debates
7. Attendance Requirements
To obtain course attendance, the student must cumulatively:
7.1. Attend at least 2/3 of the practical classes, AND
7.2. Attend at least 2/3 of the theoretical-practical classes, AND
7.3. Achieve a final practical grade of 9.50 points or higher.
The absence from a practical class requires the submission of a justification to the instructor responsible for that practical class.
The student will fail the course if the attendance requirements are not met.
8. Approval in the TP Component
8.1. To pass the TP component, the student must meet the attendance requirements for the course (please see point 7).
8.2. The student will pass the TP component if the TP grade is 9.50 points or higher.
8.3. If the TP grade is below 9.50 pints, the student may take the Appealing Exam, which will be scheduled by the NOVA FCT academic services and announced on CLIP.
8.4. If the student wishes to improve the TP grade, he/she may take the Appealing Exam ("Exame de Recurso"), provided he/she registers for ''Grade Improvement'' ("Mlheoria de Nota") on CLIP.
9. Appealing Exam ("Exame de Recurso")
9.1. The appealing exam is intended for students who did not pass the TP component but met the attendance requirements (please see point 7).
9.2. The appealing exam is also for students who wish to improve their TP grades. Students who want to improve their TP grades must register for ''Grade Improvement'' ("Melhoria de Nota") on CLIP.
9.3. The appealing exam consists of an ''Open Question,'' which will be made available one week before the exam date, and the in-person exam.
9.4. The rules outlined in points 6.2, 6.3, 6.4, and 6.6 for the TP component apply to the appealing exam.
9.5. Final grade after the appealing exam: (Grade obtained in the Open Question of the resit exam + Grade obtained in the in-person exam + Bonuses obtained in the TP component) * 0.50 + Grade obtained in the P component * 0.50.
