| In recent years, as mobile Internet and the rapid development of information technology in education, computers, tablet PCs, smart phones are widely popular, with the support of micro-learning with convenient, fast, small features adapted to the needs of the community learning. Micro lesson as an informal learning resource that the times of student learning plays an important supporting role. In this paper, micro lesson discussed from six aspects:The first chapter describes the background to the study of the subject, meaning the purpose of study, research, and then determine the method of study, followed by combing the researches on the status of the micro-lesson.The second chapter discusses the theoretical study of this subject support the core concept to define, and the characteristics of individual micro lesson has analyzed.Chapter III of primary school high school geometry class micro preliminary design analysis. Particularly in higher grades of primary school geometry teaching philosophy, teaching objectives and learners are analyzed. Finally, Graders geometry teaching status quo is analyzed.The fourth chapter in combination with other researchers in the design of micro-lessons and courses of study, put forward the principle of Graders micro-geometry lesson in the design process to follow, and select the specific content of the micro-class design.Chapter V micro choose to create a good lesson for application resources, and effect do interviews.The sixth chapter of the thesis are summarized and discussed. The author of the results obtained in this study were summarized and concluded, on the lack of presence in this study were review, we hope to have more front-line educators involved in the design work among micro lesson. |
