摘要在学习型社会不断构建中，微课受到学校、家庭、社会各方面关注，微课的使用越发普及。化学是以实验为基础的一门学科，通过化学实验操作，学生获得直观的感受。实验室制取氧气这一实验过程较复杂，是重要的知识点，对刚刚接触化学实验的学生来说很重要，但因种种原因，如学校无法提供实验装置让学生真实感受整个实验步骤，亦或者学生对实验过程的掌握有困难，需要二次学习，教师和学生对实验室制取氧气这一微课有较大需求，而以微课的形式讲解化学实验，不仅能在一定程度上解决上述问题，而且能延伸学生学习空间，促进学生自主学习。本微课主要针对初三化学非常重要的一个实验——《实验室制取氧气》而设计制作。43542

通过3DMAX建模、Flash动画制作、Premiere剪辑等技术，制作出实验室制取氧气两个实验的微课，学生经过对本微课的学习，可掌握实验室制取氧气所需实验装置、直观感受实验的步骤、物质的产生变化过程、操作注意事项及反应原理。

 Preparation of oxygen from the Laboratory

Abstract During the building of a learning society, the micro-lecture is paid more attention to by schools, families and society.The use of micro-lectures is becoming more popular. Chemistry is a subject based on experiments. Students get an intuitive feel by the Chemistry experiment in laboratory. Preparation of oxygen from the Laboratory is very complex, which is very important knowledge point . Meawhile it is very important knowledge for students who learn chemistry for a short time . But for various reasons, such as the school was unable to provide experimental equipment for students to feel the entire experimental procedure in the true environment. Another condition is that it is difficult for student to master the experimental process, they need to study second time. Teachers and students has a great demand for the micro-lecture of Preparation of oxygen from the Laboratory.but in the form of micro-lecture explaining the chemical experiments not only can solve the above-mentioned problems in a certain extent,but also can extend students’learning space .What’s more,they can promote their ability of independent learning. The micro-lecture is mainly designed for a very important chemistry experiment ,which is “Preparation of oxygen from the Laboratory”.

The micro-lecture is made by several softwares,they are 3DMAX 、Flash 、Premiere and so on. Fistly,students can grasp the names and the fuctions of the experimental apparatus .Secondly,student can get an intuitive feel about the experimental procedure and experience the step of material’s generating and changes in the process.Thirdly, student can learn the matters needed attention and the reaction principle.
