The tutorial videos on this website were produced by team members of the project 
"Lightboard Videos Enhancing VTL and Student Learning Experience for Calculus Subjects", funded by Teaching Development Grant 2022-25 and the Department of Applied Mathematics (AMA) of The Hong Kong Polytechnic University. 

​

The target audience of the videos are students taking single variable calculus subjects offered by AMA. We have selected problems at different levels fitting the syllabi and requirements of the subjects. The videos are organized by topics for easy reference. 

​

To enhance the quality, retain viewers’ attention and satisfy the need for real-time writing in tutorials, the videos were filmed using the innovative Lightboard technology with a close-up and unobstructed view of the instructor’s face, gestures and step-by-step writings on the board.
