Although allowed to discuss and work in groups, participants were required to answer the activity questions individually. The results of the questions were later compared between participants using the HDPE boards and those using standard embossed images. The results of the scores from the participation study were promising. The data showed that participants using the HDPE materials scored as much as 60% higher than those not using the boards. Furthermore, all participants were also surveyed and all had positive feedback on the enhanced tactile materials. These results demonstrate the benefits of including the improved HDPE tactile graphics in science courses.
