The purpose of this study was to investigate how nature-inspired art education might foster a sense of connectedness and collaboration in adults with Autism Spectrum Disorder (hereinafter knows as ASD) in a day program. While many studies have uncovered such beneficial art education for children with ASD, there has been little research attempted for adults with ASD. Through a single instrumental case study the participatory researcher, an art educator in a day program for adults with ASD, explores the impact of a unit of nature-inspired collaborative art making on both the participants in the day program and on their paraprofessionals. Of particular interest to the researcher is if time spent in the natural world creating art could decrease the challenging behaviors, anxiety, and stress levels of adults with ASD through assisting them to experience a connection with nature. Also addressed in this research is how this experience could simultaneously increase a connection with others through collaboration. The diverse data collection tools the researcher employs are observations from the both the researcher and the paraprofessionals as well as interviews, student artifacts and surveys. Through a narrative analysis of the case study the researcher describes that after initial challenges, most participants did experience both a decrease in challenging behaviors and a sense of connection. The researcher concludes with advocating for further research on this topic, specifically, over a greater span of time during different seasons of the year.
