School songs are giving way to school themes at colleges and universities across the United States, but these themes are not musical ditties. These are themes around which guest speakers, lecturers, and special programs for the entire school year can be coordinated. This year at Williams College in Williamstown, Mass., has been been designated a year for the celebration of the fine arts. -Additions to the campus museum and theater, and a convocation that will center on the arts, highlight the theme. Colby College in Waterville, Maine , has settled on the theme ''Celebrating diversity and confronting intolerance.'' A year-long series of discussions, workshops, and performances will include, among others, Alex Haley, author of ''Roots;'' and Collette Dowling, author of ''The Cinderella Complex.'' Technology in the classroom
A major US government effort to determine how best to utilize technology in the classroom will be centered at Harvard University. Secretary of Education Terrel H. Bell announced in late September that the National Institute of Education will award Harvard a $7.68 million contract to establish and operate the institute's new School Technology Center for the next five years.
