研究期間：10308~10407;Situated learning is usually applied in elementary natural science. It is executed with authentic environment and mobile devices to investigate students’ learning motivations, learning attitudes and learning performance in natural science. However, experienced educators think that computer technology can not completely lead students to reach their learning process. Previous researches show that inquiry-based learning strategy collocates with computer technology in situated learning environment can effectively enhance students’ learning motivations, learning attitudes and learning performance. In recent years, cloud-based handheld Apps have become new learning instruments. Handheld App is delicate application. Different from general application, Handheld App provides simple as well as useful functions and requires less storage space and power. All handheld Apps can be downloaded by cloud technology for free or charged. Therefore, this proposal applies cloud-based handheld Apps and inquiry-based learning strategy to develop inquiry-based situated learning mode. Inquiry-based situated learning mode is composed of two parts: cloud-based learning service and handheld Apps. Cloud-based learning service includes learning content service, assessment service, learning diagnosis service, portfolio analysis service and remedial teaching service. Handheld Apps includes instruction App, content presentation App, portfolio App and myth analysis App. This proposal will plan experiments for natural science to see whether the proposed mode has positive influence on students’ learning motivations, learning attitudes and learning performance.
