The talk began with the presentation of a short play, Aunt Jennifer, in which Tiffany, a high school student, attributes her moth- er’s dreary and poverty-stricken life as a checkout clerk in a supermarket to rotten luck, while attributing the pleas- ant life of her Aunt Jennifer, a software engineer, to good luck. Despite her high grades in mathematics, Tiffany rejects her guidance counselor’s of- fer to help her obtain a scholarship to study computer science.a The decline of interest in studying computer science is usually attrib- uted to a set of perceptions that stu- dents have about the subject. Many educators react to these perceptions as if they were myths and try to refute Margaret hamilton, chief software engineer for the development of the nASA Apollo program flight software, sitting in a mockup of the Apollo space capsule while checking programs them.
