A Virtual Introduction to Science Fiction
A Virtual Introduction to Science Fiction is a website put together by Lars Schmeink, a lecturer and sf scholar at the University of Hamburg. Here's how they describe the purpose of their website:
A Virtual Introduction to Science Fiction (VSF) is an online teaching toolkit for those interested in science fiction. It addresses anyone who wants to know more about the genre and provides introductory information for students, teachers and fans. As a toolkit it is specifically aimed at teachers who want to enhance their classes with, or prepare a course on science fiction. As such, you will not only find introductory essays but also pre-recorded lectures as well as further material for classroom use, all of which is prepared by experts of the field from around the world.
Use the lectures to have a specialist introduce the topic to your students, or read the introductory essays for your own preparation. Design your syllabus using the story recommendations or prepare classes with the help of VSFs further reading recommendations and in-class discussion point suggestions. You can also find recommendations for course books or free of charge online-resources.
All of this material is free of charge and fully licensed under the creative commons license (more info in the right lower corner). You can use the full toolkit including downloads of all materials. Just remember fair academic use and citation of sources.
The site includes a basic overview of the history of Science Fiction, as well as information on topics such as Race in Science Fiction and what, exactly, the genre is. There's a bunch of video lectures -- check them out!
