ab: Summary: The objective of the present study is to describe how students
discover rules underlying a certain phenomenon under question and the
process in which they mathematically justify such discovery by way of
utilizing tables and graphs in the use of the cell reference function
of spreadsheets when a problem is not easily solved through simple
symbol manipulation in a paper and pencil environment. This study was
designed as a pilot lesson study with six Korean tenth graders with the
aim of overcoming various obstacles in using computers in mathematics
classrooms in Korea, such as teachersâ€™ negative attitudes towards
technology, the absence of a computer integrated mathematics
curriculum, where some contents could be learned much better than in a
paper and pencil environment, and the absence of the proper way to use
computers in their examinations. In modelling activities, the students
could solve problem situations and find mathematical rules by using
various spreadsheet functions. The spreadsheet environment could also
help to convince students that their findings are accurate by checking
various cases of the problem situation and justifying their findings
deductively.
