A major goal of this paper is to document changes that occurred in developmental mathematics classrooms in the community college setting when the graphing calculator (GC) Texas Instruments (TI)-83 was introduced to students. The six-week intervention was conducted during the section of Intermediate Algebra in the Community College Baltimore County (CCBC)-Essex. To measure the effect of GC on student achievement in Intermediate Algebra class, a pretest/post-test and statistical paired t-test (one-tailed) were conducted. To measure student attitudes regarding the use of GC throughout the intervention, pre/post-surveys and statistical paired t-tests (one-tailed) were conducted. The results of the intervention show that there is a significant gain in student achievement and a gain in student attitude toward GC in Intermediate Algebra class with the use of GC. Appended are: (1) Survey Collaborative; and (2) Attitudes toward graphing calculators (GC) in mathematics learning questionnaire. (Contains 2 tables.)
