Combining Context-aware Ubiquitous Learning and Computer Simulation: A Lesson Learned in Elementary Science Education

Abstract

Context-aware ubiquitous learning has been recognized as an innovative mobile learning approach that enables students to directly interact with real-world natural phenomena with supports from digital technology. To enhance visualization of the phenomena, computer simulation could be used to simplify the real world using visual representation. These approaches could be used to motivate science-based learning and facilitate inquiry-based learning process in elementary school science. As such, the mobile "Answer Me" application has been created as a cloud-based instructional system to facilitate context-aware ubiquitous learning in science. In this study, the Answer Me was used to facilitate students’ investigation of scientific phenomena of sound. To enhance their comprehension about sound wave, a computer simulation, developed by Physics Education Technology research group, was employed to visualize unobservable phenomena of sound. Both technologies were combined to promote science learning experience regarding predict-observe-explain learning process. Moreover, to evaluate its impact on science learning in elementary school, 54 fifth-grade students were recruited to interact with the app and simulation through POE learning activities. They were examined conceptual understanding about sound and science motivation both before and after the intervention. The results showed that students improved their conceptual understanding about sound and the proposed approach had a positive impact on students’ science motivation of learning science by the combined learning experience.
