Indeed, students who are able to apply a correct method to any number of specific cases often cannot articulate a general pattern or relationship in natural language (see, for example, MacGregor and Stacey, 1992), and expression in algebraic symbolism is still more problematic. There is also a question mark over the status of the algebraic expression even if it is successfully constructed by the student. Lee and Wheeler (1987) suggest that it is rare for those students who do produce algebraic representation to check these expressions - even empirically by substituting in particular examples. Stacey (1989) found that only a small proportion of students responded to requests for explanation by providing mathematical justification and, similarly, Arzarello (1991) pointed to students' difficulties in providing mathematically valid justification of their suggested algebraic rules. Taken together, the evidence suggests that algebraic formulation is often disconnected from the activity which precedes it, a meaningless extra that neither illuminates the problem nor provides a means for validating its solution. Algebra is viewed as an endpoint, a problem solution in itself rather than a tool for problem solving." p 204}, interhash = {2b147eb5cb22fa1ccaa30676cbe7fd67}, intrahash = {dcc7eb49adf07d481e46a8689b26e8c9}, journal = {Educational Studies in Mathematics}, keywords = {abstraction construction ijceell06 ijtme2006 jls10 matchsticks mathematical meanings mythesis situated symbolic visual}, number = 2, pages = {203-233}, timestamp = {2010-07-07T17:03:27.000+0200}, title = {The Construction of Mathematical Meanings: Connecting the Visual with the Symbolic}, url = {http://www.lkl.ac.uk/rnoss/MA/Mathsticks.doc}, volume = 33, year = 1997 }
