Explores how the use of the graphics calculator may lead to changes in students' solution approaches and how these changes affect student achievement. Concludes that only prolonged use of the graphic calculator leads to enrichment of the solution repertoire of students and a better understanding of functions. (Contains 11 references.) (Author/ASK)

Presents a study designed to explore whether a student's use of the graphing calculator during instruction will affect their concept of function, how students' participation in a conceptual change assignment affects their concept of function, and how the graphing calculator and the conceptual change assignment interact with one another to…

Develops and validates an instrument for determining student preferences for multiple representations of functions and establishes baseline data for future research. Students showed preferences for representations of functions which varied between contextualized and noncontextualized settings. Students' preferences for the two settings were more…
