Using Augmented Reality to improved understanding of the Carbon cycle

Abstract

[EN] We designed an activity to improve students’ knowledge and understanding of the Carbon cycle, which is typically a difficult concept. We wanted users to understand the main Carbon repositories and how the element circulates, as well as how human activity is impacting it. Originally designed for an advanced biogeochemistry course on paper, it was later redesigned using augmented reality (AR) to reach a wider audience and increase accessibility to both specialized and nonspecialized audiences. The reason for using augmented reality (AR) coupled to inquiry-based learning was to motivate students to complete the activity independently and make it more appealing to a wider audience. The Carbon cycle was divided into 7 stations that will be placed throughout the university campus, and which can be accessed by anybody using an android smartphone. They can choose to complete the whole cycle and answer a questionnaire, or just browse freely. We expect that the activity will improve understanding of the Carbon cycle in a didactic, playful and non-threatening way, and motivate users to learn autonomously. We also expect it to improve long-term retention.
