It was recently brought to my attention that I did not acknowledge the intellectual and copyrighted work of Dr. Judith Singer (Harvard University) in materials that I had used and previously posted on this site. These materials constitute the intellectual work of Dr. Singer and should receive proper attribution as such. I also failed to confirm with Dr. Singer the ways that I wanted to use the materials after she graciously shared them with me. Subsequently, I have removed the materials and apologized to Dr. Singer for my careless oversights and taken full responsibility for my actions. Mea culpa.
While embarrassing for me, I hope readers of this post can learn from my mistake and allow this to serve as a reminder that vigilance to attribution and acknowledgement needs to go beyond the scholarship that is produced for journals and research, and must also extend to materials that we use in our daily work such as course materials.
This attention to citation is even more crucial today as technology allows the acquisition and sharing of other people's thoughts, ideas, materials, and content via the click of a mouse. While the sharing of great ideas and content is important, giving credit to the person (or people) who developed those ideas is equally important.
