The Micro-lecture Design And Implementation Of Database Principles And Applications

With the rapid development of network technique and the progress of the Science and technology in education,the traditional classroom teaching can’t meet the requirements of the age,and the teaching mode is also changing.Micro-lecture,as a kind of new learning resource,is developing rapidly at home and abroad.Along with the development of E-learning and mobile internet learning,the basic idea,design and application of Micro-lecture gradually become one focus.Database Principle and Application is one of the core courses of computer science,so learning the database technology well is very necessary.Part of the course is made into micro-lecture for students to learn,by which the teaching form can be improved and the students can broaden their horizons,thus the students can make full use of the extra fragments of time for effective learning,higher learning efficiency and strong practical value.According to Ministry of Education and the curriculum system of computer science and technology,through the combination of the requirements on the teaching syllabus of Database Principle and Application in higher college,the writer makes a comprehensive analysis of the course and analyzes 6 core knowledge units,a total of28 episodic knowledge to help the research of teaching design and teaching methods,and designs micro course ware of 28 episodic knowledge.This article provides a complete set of tools from the screen recording,video editing to video output at the platform Camtasia studio where it is very convenient for screen recording,voice processing,adding transition effects,synching up,annotation processing,the effect of adding the cursor and subtitling,adding copyright information project,watermarking,etc.The characteristics of this paper mainly reflect in the followings:(1)Combining the animation and video production,parts of the knowledge content that are not easy to understand can be shown through the animation,then the difficult points and doubts will be easy to understand and master.(2)Combining the examples and environmental demonstration,then the students can analyze the difference of the variety of SQL operation through the operation results.(3)Use mobile phone to film and connect the points of knowledge and the process of calculation through recording,and then get the best of knowledge.(4)Add the module of exercises,teachers can know about whether the students master according to their answers.(5)The video images of micro course ware are clear,sound and image are coordinating,the division of knowledge is reasonable,so teachers can explain clearly in a short time.This group of micro course ware can stimulate students’ interest in learning to a certain extent,develop an auxiliary role for students to understand and deepen the knowledge of the database and improve the students’ learning efficiency,and which can help students to study independently.
