The required textbook for this course is Research Design: Qualitative, Quantitative and Mixed Methods Approach (6th Ed.) by Creswell, J.W and Creswell, J.D (2022). If you are unable to purchase the hard copy, here is the e-book (5th edition) version free for you to download and use. 

Note: 

My lecture slides are mainly based on this textbook. Please refer to it for further reading and understanding of the concepts learned in class, as lecture slides can be quite brief.
