Abstract

The purpose of this experimental research was to examine the effects of the use of the TI-84 Plus Graphing Calculator on the achievement of Coordinate Algebra students to ascertain if the use of this tool promotes student achievement and increases the probability of students passing the Coordinate Algebra Milestones Assessment. Successful completion of Coordinate Algebra determines whether students receive a high school diploma and without a high school diploma students are ensuring themselves lives filled with low paying jobs, short-term employment, and a greater possibility of being incarcerated.

The participants for this research consisted of all regular education students who are classified as freshmen and divided into two groups for comparison purposes. The dependent variables for this study included the following: (a) the posttest Coordinate Algebra scores for all students in the control group whose teacher used traditional methods of teaching Coordinate Algebra, (b) the posttest Coordinate Algebra scores for all students in the experimental group whose teacher used the TI-84 Graphing Calculator, (c) the students’ perception on the impact of utilizing the TI-84 Plus Graphing Calculator, and (d) the teachers’ perception on the impact of utilizing the TI-84 Plus Graphing Calculator.

The independent variables for this study were as follows: (a) the groups the students are in with 1 = control (traditional method) and 2 = experimental\treatment (TI-84 Plus Graphing Calculator), (b) the gender of the student, (c) the pretest score, (d) student attendance, (e) socioeconomic status, and (f) difference in Coordinate Algebra score gains.

The following question drove this research: What is the effect of the use of TI-84 Plus Graphing Calculator on the achievement of Coordinate Algebra students as measured by their posttest scores? Furthermore, this experimental research examines the correlation between factors such as the non-use of the TI-84 Plus Graphing Calculator, gender and socioeconomic status (independent variables), and the academic success rate (dependent variable) of Coordinate Algebra students.
