I show a lot of photographs in my classes, and I mean a lot! I think I have used Power point once out of all of my lessons, as it's just so much easier to use a photo friendly site like Pinterest.
Where I am placed they don't use Pinterest as a teaching tool, because they never really had too. There isn't a lot of 'chalk and talk', because that's the nature of the course. I don't do a lot of 'chalk and talk', but I am aware that I need to introduce the students to different photographers, and I like to show video clips or articles to go along with the subject. The other lecturers have been doing this for years and don't hesitate to just bring up the videos or websites during the session, but this is because they have the confidence to do that. I am very new to this teaching malarkey. Having all my resources in one place makes my planning and my life easier. 
In my more recent lessons, when I have been looking at photographers, I have put a lot more work on the Pinterest board than I'm actually going to look at. I leave this page open on the Interactive whiteboard and during the lesson if the students want to go up and look at some other work, they can do so. Just by clicking directly on the board. This gives them more access to resources if they want it. I have circled the images I actually used to present the lesson.
The last great thing I'm going to say about Pinterest, is that my students have instant access to all the resources I used in class. All they have to do is go to my Pinterest page and all the lessons are there! This helps them find exactly what they are looking for when doing visual diary work. Of course like other colleges and universities they have a virtual learning environment (VLE) that they use, Moodle. But in my lessons I am mainly showing photographs and videos, Pinterest is a much easier platform to look at images and video rather than Moodle. Pinterest is for me, the most useful teaching tool out there.
