Common Craft has been producing unique explanatory videos for more than a decade. I've been using them in my classroom and workshops for nearly as long. Common Craft videos provide clear and concise explanations of nuanced topics ranging from the Electoral College to copyright to digital citizenship. Their latest video explains incognito or "private" mode in your web browser.
Private or Incognito Browsing Explained by Common Craft teaches viewers what the incognito or private browser function does, what it doesn't do, and the legitimate reasons for using it.
Applications for Education
This video does a good job of dispelling the mistaken belief that some students have that using incognito or private browser windows hide all of their online activities. The video also does a good job providing examples of legitimate uses for incognito windows. In fact, I often tell teachers to use incognito windows when they want to see the student view of an assignment or website without signing out of their teacher accounts.
Disclosure: I have a long-standing in-kind relationship with Common Craft.
