University of Hawaii researchers find use of the TI-Navigator™ Classroom Learning System adds value to graphing calculators in improving student comprehension and engagement

DALLAS - (November 15, 2005) - Research results announced today show using the Texas Instruments TI-Navigator™ Classroom Learning System with graphing calculators improves student performance in Algebra.

The study of 51 eighth-grade Algebra I students, conducted by the University of Hawaii Curriculum Research & Development Group, found that students who used the wireless classroom technology showed more improvements in their conceptual understanding, classroom interactions and engagement in solving problems than students using graphing calculators alone.

When measuring students' achievement on pre- and post-tests of linear equations, the study found that 15 students improved their overall score in the classroom using the TI-Navigator system, versus 12 students in the classroom that did not use the technology. While both groups performed the same on graphing skills, the TI-Navigator group did better on conceptual understanding. Both classrooms used TI-84 Plus Silver Edition graphing calculators.

Classroom observation data showed students using the TI wireless technology engaged in tasks significantly faster - 1.5 seconds compared with 19.75 seconds in the classroom using only the graphing calculators. Students using the TI Navigator system spent more time working on tasks, wrote longer and higher quality responses to open-ended mathematics questions, and interacted more with their peers on group assignments.

"While graphing calculators help students achieve in Algebra, our findings show the use of the TI-Navigator wireless system increases the value of graphing calculators by advancing student comprehension and classroom engagement," said Dr. Barbara J. Dougherty, principal investigator from the University of Hawaii Curriculum Research & Development Group. "The system provides more opportunities for students to assess their work and collaborate with their peers. It also enhances classroom management because students start tasks quicker and stay focused longer."

Research Process
The study occurred from January 3 to February 25, 2005. It included two sections of Algebra I students, the first comprising 25 students and the second with 26 students. The sections were matched in terms of gender, achievement, socio-economic status and ethnicity.

The experimental group used the TI-Navigator system and TI-84 Plus Silver Edition graphing calculators, while the control group used only the TI graphing calculators. Both groups used the same algebra program developed by the Curriculum Research & Development Group and were given the same tasks, questions and activities each day.

In the content assessment, students in both sections were given a pre- and post-test constructed of 15 released items from the Third International Mathematics and Science Study (TIMSS).

The study collected anecdotal data through student responses to written prompts to track their use of and attitudes toward the mathematics technologies, as well as classroom observations collected by researchers who documented the amount and quality of student interactions.

The award-winning TI-Navigator classroom learning system provides wireless communication between students' TI graphing calculators and the teacher's PC. The technology allows teachers to instantly assess student understanding by viewing their work on the graphing calculator in progress, polling students with quick quizzes, and creating a forum for students to anonymously participate in classroom-wide activities. The system is in use nationwide and works with TI's latest TI-84 Plus graphing calculator family as well as its popular TI-83 Plus products.
