Before students engage in the use of technology in an educational setting, they should be familiar with the concept of Digital Citizenship. Check out the video below and Mia MacMeekin's great infographic summary of Digital Leadership at right. We'll talk more about this in class throughout the year and utilize this great source devoted to better technological citizenry.
We'll explore these and more educational applications for use by teachers and students in high school. Let me know about others you use and I will include links to them here.
