Informal and Formal Knowledge: The Domain of Percent.
Risacher, Billie F.
This paper reports a study of student knowledge of percent at the elementary, middle, and secondary levels. The study concentrated on three areas: (1) an analysis of the percent concept, its symbols, and procedures; (2) the child's naturally constructed base of informal knowledge of the percent concept; and (3) what formal knowledge develops in terms of concepts and procedures as a result of traditional instruction. A written test containing a variety of questions to indicate informal and formal knowledge of percent was given to classes of students in grades 5, 8, and 11. Results showed that students used a variety of formal and informal strategies indicating flexible knowledge of concepts and procedures. Also, it was found that students had some understanding of percent prior to instruction. Contains 17 references. (MKR)
