I was looking at the site for the Timeliner software, and really liked what I saw. It would be a perfect fit for an Art History class for the students and for me. In looking at all of the features, I was surprised to see that it comes with a browser, so students can research the information they need and apply it to their presentations without leaving the program. This actually includes grabbing pictures, information, and sound media with citations from websites. It includes activity files that I can customize to the class, free Grolier information, and the ability to make class activites with the information to test the students subject-retention.
I would definitely use this to put together chapter timelines in my art history classes, because I think it is really helpful to have a visual layout when the chapter covers 100 years of time. This would fit together really well with using the 30,000 Years of Art book from Phaidon Publishing. I want to take Art History, a very lecture-oriented class and make it more interactive. This is easily achieved with timelines, especially when I can make them myself, or choose to have the students make them.
This site would also be helpful for so many other classroom applications, and I would totally recommend that teachers from every different discipline take a look at it.
As a side note, I really want to keep up with this website and have an education blog that I can send students to if they need to know the homework assignments, what we covered in class, etc. I would also love to record class lectures and turn them into podcasts for students to go back to or listen to if they were absent.
