🦾 Motivations

../../../../_images/inspirations3.png

Linear algebra is the foundation of modern science, especially electronic science. Modern computer technology can solve various scientific and engineering problems, and its core functions deeply rely on linear algebra. Take the currently hottest artificial intelligence as an example: advanced AI programs use big data and a variety of algorithms to achieve astonishing functions. However, all their underlying computations cannot do without the “ordinary and unremarkable” foundational knowledge of linear algebra. In many other computer-related fields, such as digital business, electronics, mechanics, vehicles, manufacturing, packaging technology, and electrical engineering, it is even more so. If we compare modern science to an inverted pyramid, then undoubtedly, linear algebra is one of the base layers of this inverted pyramid. A solid foundation in linear algebra will never disappoint you!

✏️ How to pass?

You will receive two grades:

  • A general grade: It will make up 30% of your final grade. And itself is made of

    • Class participation (4% of the final grade, 13% of the general grade)

    • Assignments and chapter tests (16% of the final grade, 53% of the general grade)

    • Online learning and testing (10% of the final grade, 34% of the general grade)

  • A final examination grade : You will take part in a final written test. Its grade will make up the

remaining 70% of your final grade.

For example, if you score 90 (of 100) for your general grade and score 60 (of 100) in the final written test, your final grade will be 90*0.3 + 60*0.7 = 69.

🔋 You pass if your final grade is not lower than 60.

⌚ The final written examination usually happens in the weekend of the second week from the last lecture.

🪫 In general, if you do not pass, in order to obtain a position in the resit exam (make-up exam), you will need to at least score 60 for your general grade and at least score 30 in the final exam.

⏰ The resit exam (make-up exam) usually will happen on the weekend before the first week of the next semester. In order to pass the course through the resit exam, you will have to score at least 60 in the resit exam. That is saying no general grade will be taken into account anymore.

🔂 If you fail again in the resit exam, you will have to retake the course.

On top of this, everyone should also follow the 📜 Code of Classroom.


📊 Teaching evaluation

There will two Teaching evaluations, the early stage evaluation and the final evaluation.

  • Early stage evaluation: It happens around the fourth lecture week. Through it, you can let the lecturer know how to improve the lectures before it is too late.

  • Final evaluation ：It will be released by the office of academic affairs at the end of the semester.

The early stage evaluation now is open. Please download the 📈evaluation_form.pdf, fill in it (by eithor inserting digitally or printing and hand-writting), and send it back to me.


💻 Online learning and testing

Online learning and testing will be available when the course is 60% completed.
