In 1975, Dr. Philip Uri Treisman, a mathematics professor at University of California-Berkley, began to investigate why Asian American students seemed to do so much better in freshman mathematics than did other minority students. The following are highlights from his findings:
   The Black students Dr. Treisman studied were raised to be self-reliant. They worked on their own and did not ask for or expect to receive help from other people. In high school this strategy worked, but it backfired in college and the students floundered.
   The Asian students Dr. Treisman studied collaborated much more. They helped each other figure out what they needed to know. They worked together very intensely, and they were very successful mathematics students.
