This study examined students' perceptions of the Tablet PC as an instructional tool for teaching Calculus. A thirteen item survey was developed by the researchers and administered to 103 students in an introductory Calculus course at a large university in the Northeast of the United States. The purpose of this survey was to collect data regarding students' perceptions about the use of the Tablet PC as an instructional tool to effectively and efficiently cover the material taught in class. Results suggested that students perceived that the Tablet PC allowed them to pay better attention to the material presented in class, helped them better understand the material presented in class, and helped the instructor cover the material in an efficient way.
