Built By Teachers and For Teachers

PBS worked with math teachers in all aspects of this resource's development. To further refine the organization and presentation of the database contents, an outside research firm conducted two rounds of focus groups with a diverse group of math educators.

The database also provides useful and relevant search results thanks to a team of six experienced math teachers representing various grade levels who carefully reviewed each Mathline video, divided each into 1-10 minute clips that illustrate specific teaching techniques and the instruction of math topics, wrote descriptions for each clip, and then mapped each clip to search parameters identified for the database. Additional checks in the editorial process helped to ensure consistency among the educators work.

Finally, the videos themselves were produced by math educators in collaboration with the video production team at PBS member station Thirteen/WNET, and the National Council of Teachers of Mathematics. The videos are not scripted; rather they show actual teachers in classrooms with their regular students, working together on a standards-based lesson.

Technical Needs

In order to use the Mathline searchable video clip database, your computer needs to have Netscape or Internet Explorer, version 4.0 or higher. Also, you will need to be connected to the Internet with a 56K dial-up connection or with a high speed Internet connection of 220K or better (e.g. T1, DSL, etc.). As you click to watch a video clip, you will be prompted to select the connection speed at which you would like the video to be played. The faster the speed of your connection, the better the video will look. The videos are also set up to play on your computer with a RealMedia or Windows Media player. One of these players is probably already available on your computer. If not, they can be downloaded free of charge and easily installed.

If you are unable to watch the videos for any reason, you can alternatively access the written lesson plans that are used by the teachers in the videos. They are listed on the initial search page for grades K-2, grades 3-5, grades 6-8, and grades 9-12.
