This course uses a periodic assessment methodology, with the following characteristics:
1) Preparation and discussion of an individual paper/report (exceptionally by a group of two students), written in PowerPoint format, vertical page, using Times New Roman font, size 24, with 12 to 15 useful lines per slide and at least 25-30 slides (number of students in the group), with full pages of descriptive text. The 25-30 slides (number of students in the group) does not include the cover, index, and bibliographic references and includes a chapter on equipment maintenance associated with the new technology described. The bibliography must mention at least three books and/or three scientific articles published in journals. The work/report must be submitted by 9:00 am on Monday of the ninth week of classes. Analysis and discussion of the reports will occur throughout the remainder of the semester. This assessment component contributes 50% of the final grade, on a scale of 0 to 20 points. 2) Assessment test, which is administered during official exam periods. This will last a maximum of 2 hours and will comprise 15 questions covering the entire course, five of which are developmental and ten are multiple-choice. This assessment component also contributes 50% of the final grade, on a scale of 0 to 20 points.
Multiple-choice questions answered incorrectly will be discounted
corresponding to one-third of the grade (up to -0.33333333 points).
Multiple-choice questions may contain more than one correct answer.
Only students who attend 75% of all classes may pass the course.
NOTES:
a) Students who do not attend at least 50% of the total contact hours will not be assessed this academic year.
b) Student approval is conditional upon meeting the following requirements:
b.1) Achievement of a minimum score of 8 points on the final exam.
d.2) Average grade of at least 9 points, on a scale of 0-20 points, in the component related to the preparation, presentation, and discussion of the paper/report.
c) If the failure is due to the student not having achieved the minimum required for passing the final exam or the paper/report, this insufficient grade will be recorded on the report card.
