This module is the forth module of calculus, about multi-variable calculus. The main contents include differential calculus for multi-variable functions and multiple integrals. By learning multi-variable calculus, where the contents change from one to three-dimensional questions, students can receive training on non-objective and special imagination.

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment
• Online automated feedback

How will my Feedback be Delivered?

Assignment feedback individually , and the feedback will give the marks of the assignment by students' performances. Group feedback will be used when there is a team work given. Online feedback happens when online question and answers exist, the students' performance will be marked as assessments.
