Traditional science instruction is typically reliant on visual modes of learning, such as textbooks and graphs. Furthermore, since science instruction is often heavily dependent upon visual cues, students with visual impairment often do not have access to the same educational opportunities in most science classes (Jones, Minogue, Oppewal, Cook, & Broadwell, 2006). However, advancements in tactile technology (haptics) are allowing individuals with visual impairments to discover science concepts in revolutionary ways. Haptic feedback devices allow users to experience computer simulations through tactile sensations. Students with visual impairments in science classrooms can now use haptic devices to "feel" objects and processes in science, such as exploring an animal cell's organelles (Jones et al., 2004). The study presented here explored the efficacy of the Novint Falcon haptic device from Novint Technologies, a USB-enabled haptic device that is designed to replace a mouse while a participant is utilizing the computer for simulations or gaming. Participants in the study used the Novint Falcon device with the instructional program ("Pollen Grain") which allowed them to maneuver and control an object (a pollen grain) that was constantly subjected to the random motion of surrounding particles in a closed system. The intensity of the force feedback depended upon the temperature and pressure settings in the simulation. When operating the haptic device along with the computer simulation, participants were able to "feel" the numerous particles randomly bombard the object they were guiding in the simulation. The concept of particle movement is crucial for individuals to understand various interdisciplinary science concepts, such as heat; the formation of viral capsids, proteins, and structures; and processes such as osmosis. The results of this pilot study suggest that the haptic technology and software program investigated support elementary and secondary students' learning about particle motion, temperature, and pressure. The results suggest that the Falcon haptic device has the potential to be a useful tool for students with visual impairments to learn science concepts and processes. Topics such as thermal energy and temperature are difficult for students to conceptualize (Harrison & Treagust, 1996), and the changes in the assessments showed that participants in the present study made gains in their understanding of these topics.
