We are pleased to announce that the 53 public use lessons collected as part of the TIMSS video studies are now available for everyone on a new website, timssvideo.com. Users must register on the site to access the videos, but registration is free. In addition to the 53 full-length videos of eighth-grade mathematics and science lessons from seven countries, the site also provides full English-translation subtitles for each lesson, a searchable transcript, and a set of resources collected with each lesson such as scanned text materials and teacher commentaries. The site also includes a discussion forum where users can share ideas for how they are using the site, and suggest new features that might be added in the future. The site is a project of UCLA and the Carnegie Foundation for the Advancement of Teaching. Funding was provided by The William and Flora Hewlett Foundation. Please explore the site, and feedback is always welcome!
