ab: Summary: We analyse the role of the spreadsheet in the development of
algebraic thinking of grade 9 students in the study of 2nd degree
equations. The research aims are (i) to understand how students
approach their tasks in the spreadsheet, i.e., which representations
they use and how they coordinate them, and (ii) the extent to which
using spreadsheets in conjunction with working with paper and pencil,
influences the development of algebraic thinking, particularly in the
use of more formal (algebraic) language. Data analysis focuses on the
productions and dialogues of a student while solving tasks with the
spreadsheet in the classroom. The spreadsheet, articulated with working
with paper and pencil, was important to the student’s developing of
her algebraic thinking in this topic, boosting the use of a more formal
language.
