Texas Instruments demonstrated its TI-Navigator system, which offers schools another solution for managing a math or science learning environment. A combination hardware and software system, TI-Navigator includes individual system hubs, which connect with four graphing calculators, and software that allows instructors and students to collaborate and work individually. The system includes a wireless access point to allow wireless communication between the teacher’s PC and the students’ graphing calculators. The standard system can be bought to meet needs of 16 or 32 individual students per classroom, but TI can supply a classroom with up to 40 of the devices. TI-Navigator allows for anonymous student collaboration through the calculators. Results and average student scoring can be shown on a whiteboard or projected onto a large screen by the instructor. Teachers say the system allows for greater student ownership of the class materials. The system includes modules designed to create and instantly grade online quizzes and exams. The results of students’ work can be tracked in a color-coded graph that instantly displays overall student performance.
