Design of a Microlecture Mobile Learning System Based on Smartphone and Web Platforms

摘要

This paper first analyzes the concept and features of microlecture, mobile learning, and ubiquitous learning, then presents the combination of microlecture and mobile learning, to propose a novel way of micro-learning through mobile terminals. Details are presented of a microlecture mobile learning system (MMLS) that can support multiplatforms, including PC terminals and smartphones. The system combines intelligent push, speech recognition, video annotation, Lucene full-text search, clustering analysis, Android development, and other technologies. The platform allows learners to access microlecture videos and other high-quality microlecture resources wherever and whenever they like, in whatever time intervals they have available. Teachers can obtain statistical analysis results of the microlecture in MMLS to provide teaching/learning feedback and an effective communication platform. MMLS promotes the development of microlecture and mobile learning. A statistical analysis of the implementation of the system shows that students using MMLS to assist their learning had improved results on their final exams and gave a higher evaluation of the curriculum than those who did not. The advantages and disadvantages of MMLS are also analyzed.
