The Southwest Educational Development Laboratory (SEDL) serves the Southwest including Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. Although most of SEDL's SCIMAST Access Centers are specifically targeted for these specific states, the SCIMAST website offers an array of broadly applicable resources on science and mathematics education. One feature of the site is the Classroom Compass, "a thematic publication designed to link issues in mathematics and science education to instructional ideas and resources." Each issue explores a theme in depth, illustrating instruction around that theme and providing informational resources and materials for further investigation. Topics include constructivism, cooperative learning, Rhythm of Mathematics, science as inquiry, and using community resources. Visitors can also search the extensive resource database for mathematics and science instructional materials and resources.
