Algebraic Procedures Used by 13-to-15-Year-Olds Author ( s ): Agnieszka Demby Source : Educational Studies in Mathematics , Vol . 33 , No . 1 ( Jun ., 1997 ), pp . 45-70 Published by : Springer Stable URL : http://www.jstor.org/stable/3483004 USED BY 13-TO-15-YEAR-OLDS ALGEBRAIC PROCEDURES This paper is a report on the procedures used by students ( aged 13 to 15 ) who were to simplify given algebraic expressions or , put differently , to perform given algebraic operations , e . g ., The main questions considered here are : What procedures are used by the students while performing such tasks ? Are they mostly procedures that were explained and used earlier by the teacher ? Or perhaps most procedures are spontaneous , that is , invented by children themselves ? What can be said about the developmentof students ’ procedures ? Are they stable over a long period ? Is there a correlation between the types of procedures and the achievenments of the students using them ? How do the students the equality sign in an algebraic identity such as 6x + 3x = 9x ? interpret Clarifying the terms In the sequel , the term operation will be confined to four basic arith- metic / algebraic operations , supplemented with squaring and cubing .
