I find this difficult to do, especially with young people who have grown up with wireless Internet, smart phones, etc. It's hard to imagine how to gain information when it has always been at one's fingertips. In addition, new apps and tools are constantly being created, often just to replace another one that wasn't ineffective. It's a matter of conspicuous consumption in my mind. So I'm having difficulty not being pessimistic about how get students to think critically about digital tools.
