摘要：The shortage of teachers for today’s schools seems to be a topic for discussion and research on a continuing basis. Administrators are currently filling classrooms with people who are either not qualified or underqualified to teach a particular grade level or subject. Forty-one percent of all secondary school students enrolled in physical science classes, chemistry, physics, earth science or space science are taught by teachers without a minor or a major in any of these physical sciences (Ingersoll, 1997). Over one quarter of all secondary school students enrolled in math classes are taught by teachers who do not have either a college major or minor in math or math education (Ingersoll, 1997). Teacher placement days, which once resembled opening night at a Broadway show, now find administrators scrambling to find someone to talk to.
