A growing body of research states that the use of the TI-NavigatorTM system and graphing calculators improves student engagement, understanding and performance.
|
| Specific research studies show that the use of the TI-Navigator system:
|
| • | Improves student performance in algebra. |
| • | Enhances conceptual understanding by students. |
| • | Keeps students on task and more focused on completing assignments. |
| • | Fosters classroom interaction, group learning and student discussions. |
| • | Sparks greater student engagement and immediate attention in solving problems. |
| • | Strengthens the teacher’s ability to assess and guide student performance and understanding. |

Study Description |
Key Findings |
"TI-Navigator Technology and Algebra I"
November 2005
University of Hawaii Curriculum Research & Development Group (CRDG)
Dr. Barbara J. Dougherty (PI), Kristie Akana, Christy Cho and Jonathan C. Fernandez (University of Hawaii CRDG) |
An experimental study of two 8th grade Algebra 1 classes: both using TI-84 Plus Silver Edition graphing calculators and one using the TI-Navigator system. Classes were assessed on conceptual and skill items based on the study of linear equations.
Observational data was also analyzed: student response times, time on task and student interaction and collaboration. |
- Students showed improvement in the areas of: conceptual understanding, classroom interactions, quantity and quality of responses, time on task and time to start tasks when teachers incorporated the TI-Navigator system with graphing calculators into their instruction.
- Item analysis showed that both classes performed at the same skill level on graphing, but the one class that also used the TI-Navigator system experienced greater conceptual understanding.
- Use of the TI-Navigator system prompts students to engage on tasks faster, remain focused and take part in productive group interaction.
- Observational data showed that response times by students using the TI-Navigator system to initiate tasks was significantly faster compared to students using only graphing calculators. The time on the task was reported to be longer as well. The same data shows that the TI-Navigator system provided in-depth discussion points, leading to improved student interaction and collaboration.
- This study showed that students using the TI-Navigator keyboard to complete LearningCheck™ assignments (versus paper and pencil) were able to provide more detailed, higher quality responses to open-ended math questions.

"Improving On Expectations: Preliminary Results From Using Network-Supported Function-Based Algebra"
October 2005
The University of Texas at Austin
Walter Stroup, Lupita Carmona and Sarah M. Davis |
A quasi-experimental study on the use of the TI-Navigator system along with the algebra curriculum in up to 25 days of classroom instruction during an 11-week period.
Researchers compared results from the state-administered 8th grade TAKS test and 9th grade Algebra TAKS test. |
- Strong evidence shows that the use of the TI-Navigator system significantly improves student scores in algebra.
- The TI-Navigator system helps students in the reduced lunch category, female students and Hispanic students achieve higher test scores, successfully leading to a reduction in the achievement gap.

"Research Relating To TI-Navigator"
2004
SRI International. Prepared for Texas Instruments. |
An analysis of 26 classroom-based studies on related communication system technology to identify key benefits recognized by teachers.
Empirical research identifying effective teaching practices relating to improved student interest, engagement and achievement were correlated to TI-Navigator system capabilities. |
- Students are more engaged, able to understand complex subjects, more interested in topics, able to gauge their own level of understanding and more willing to take part in discussions when the TI-Navigator system is incorporated into classroom instruction.
- Teachers are able to promote greater discussions and interactivity, to assess and guide student performance, and extend the classroom topics beyond the allotted class time when the TI-Navigator system is incorporated into classroom instruction.
- Use of the TI-Navigator system: supports multiple question types and provides immediate feedback and assessment, helps direct students toward mastery-oriented goals, engages prior knowledge by collecting everyone's responses to problems and showing variations, facilitates conceptual reasoning and fosters collaboration.

"Lessons from SimCalc: What Research Says"
TI Research Brief #6
|
For over a decade, researchers of the SimCalc Project, based at the James J. Kaput Center for Research and Innovation in Mathematics Education at the University of Massachusetts Dartmouth, have been striving to fulfill their vision of "democratizing access" to important, advanced mathematics. To this team, democratizing access has meant two things:
(1) enabling children from all backgrounds to learn conceptually-rich mathematics and
(2) scaling up to demonstrate measurable impact throughout whole districts, regions, and states.
A core belief of the project is that technology can provide a new representational and connectivity infrastructure for teaching and learning. Coupled with the right curriculum, teacher professional development, and school leadership, this infrastructure can make advanced concepts --including those usually addressed only in an elite Calculus course-- accessible to many more students and at early earlier grade levels.
The SimCalc instructional approach emphasizes developing multiple, interrelated mathematical fluencies including both procedural and conceptual (declarative) understandings. |
- SimCalc is a promising model for teaching mathematics in a technology-facilitated environment. At the heart of the model is the use of technology to integrate graphical, dynamic and linguistic representation to enhance student learning. At Texas Instruments, we see implications that extend far beyond the project and are important to the entire graphing calculator and classroom networking community in math and science education.
