Hi Lawrence,
Thank you for sharing your screencast! I appreciate the way you explained the different components of the badminton racket. Before reading your post, I had no knowledge of a badminton racket and never thought of the different materials and specifications. I learned lots from your post and love how you decided to choose visuals over just narratives to teach. I found your approach to learning effective in understanding the video and I can see you put lots of thought into how to incorporate the principles to teach your chosen audience.
