New technologies and newopportunitiesThe Open Educational Resources (OER)movement is driven by rapidly changinginformation and communication technologies.In the ubiquitous learning environment educational audiences should feel free to chooseor switch their learning devices based on theirpersonal needs and different environments.
New technologies and newopportunities The rise of new handheld technologies, such as smart-phone, iPad, tablet PC, notebook…, requires new mobilelearning behaviors: multi-touch screen with zoom-in & out function, differentoperating systems, lack of keyboard and mouse….. The content of conventional OCE might not becompatible with mobile devices. This study aims to apply the cloud-based solution forOpenCourseWare system to meet the need of learningvia various devices.
OCW of National Tsing Hua University National Tsing Hua University (NTHU) launched theOpenCourseWare (OCW) project using Moodle platform in 2008. To enlarge educational audiences and extend the reach of OCW,NTHU updated the system with the cloud-based solution in 2010.
OCW of National Tsing Hua University The NTHU OCW adopted the cloud-based platform
OCW of National Tsing Hua University The OCW files were created in various formats suitable fordifferent devices. The videos published in multiple formats can ensurethe accessibility of learners with different devices.
Method This study used web metrics tool -the Google Analytics(GA)- as the primary research instrument to discover theuser’s perspectives with different devices. This study interviewed with the production team of NTHUOCW, including faculties, instructors, and teachingassistants, to understand the process of preparinglearning materials in the initial moodle version andupdated cloud-based version.
