Nestled in the back of Mānoa Valley, Lyon Arboretum offers visitors the unique opportunity to see more than 6,000 different types of tropical and subtropical plants. Frequented by researchers and student groups alike, the grounds boast more than 7 miles of trails that wind through the rolling, humid grounds. Wondrous flora and fauna await visitors who are able to navigate the arboretum on foot, but those with physical limitations are not always able to reach the same areas of the garden. Over the last year, however, an assistant professor in UHM’s College of Education has worked with students to build an Open Educational Resource (OER) that offers an immersive virtual tour with activities along the way.
Shamila Janakiraman, an assistant professor in the UH Mānoa College of Education’s Learning Design and Technology (LTEC) program is collaborating with her students to create immersive virtual tours of the arboretum within an OER book on UH’s Pressbooks platform. Pressbooks is a free, open source software project which makes it possible for UH-affiliated faculty, staff, and students to create digital books that are print-ready but also able to leverage exciting web technology to engage students. Professor Janakiraman participated in an Introduction to OER workshop offered through the UHM Center for Teaching Excellence (CTE) in Fall 2023, and has since worked with students in her courses to build out content and curriculum to extend the beauty of the Lyon Arboretum to broader groups. Using the interactive tool H5P and the Augmented Reality platform Assemblr, visitors to the OER book can “walk” up the trails and learn about the plants, their uses, hear the songs of endemic birds, and get up and close with many features of the garden.
Dr. Janakiraman and her team of students designed the OER book based on aspects of the Cognitive Theory of Multimedia Learning (CTML), wherein learners have the opportunity for deeper levels of learning when text, images, and interactive components are part of the instruction. As part of a service-learning experience Dr. Janakiraman’s LTEC graduate students constructed the OER book, contributing content and activities, at the same time learning about the systematic design and development of learning experiences.

The book content has also been made into multiple versions for different audiences, one with simplified language for junior learners, and one with content broken into smaller chunks for students with special needs. This work also opened up opportunities to present at conferences to share the instructional design experience of creating an OER. Dr. Janakiraman and her students presented their design in practice at the Association of Educational Communications and Technology (AECT) in October 2024. Dr. Janakiraman is grateful to her students Andrea, Charissa, Justin, Ruadhán, and Yada, without whom this project would not have been possible. She also thanks Raedelle Vanfossen, the Education Manager at Lyon Arboretum and her nature camp staff for their support every step of the way.

You can find the book on the UH OER Pressbooks site.
