Misconceptions about everyday scientific phenomena, such as the seasons, gravity, and light, are common in the general population. to assess the degree to which the university students about to recieve a middle school teaching credential shared misconceptions, a science quiz consisting of 10 multiple-choice questions was given to a random sample of 52 such students.
