Due to the advance of modern medical technology, the average age of global population increases continuously in recent years. In 1993, the society in Taiwan had already reached the criterion of aging population, bringing the country an important issue of looking after old people which could not be ignored by its society. In this study, a wireless sensor(More)
The lotus effect is a learning topic of nanoscience commonly seen in elementary schools. However, nanostructures cannot be observed with naked eyes or using general microscopes. Lacking interactive operating environments, it is not easy to inspire students to explore nanophenomena. This study used virtual reality (VR) technology to develop two physical(More)
In recent years, many high-tech instruments have been developed to investigate the nanostructures of materials. For example, the transmission electron microscope (TEM) is capable of imaging at a significantly higher resolution than light microscopes, enabling scientists to examine the very fine detail of materials even as small as a single column of atoms.(More)
A campus butterfly garden is a useful teaching resource for studying insect ecology because students can learn about a butterfly’s life cycle and become familiar with its habitual behavior by breeding and observation activities. However, it requires professional construction and maintenance for sustainable development, so very few schools can afford to own(More)
Virtual reality (VR) learning environments can provide students with concepts of the simulated phenomena, but users are not allowed to interact with real elements. Conversely, augmented reality (AR) learning environments blend real-world environments so AR could enhance the effects of computer simulation and promote students’ realistic experience. However,(More)
The campus ecological pond is an effective tool to assist science teaching since it allows students to obtain knowledge of aquatic biology in freshwater environments by practical observation. In this study, a virtual campus ecological pond was developed for applications in science education in elementary schools. The system integrates real ecological(More)
