Description
Technical field
The present invention relates to a kind of long-distance education field, more particularly to a kind of platform of online teaching and its teaching methods.
Background technology
In traditional teaching pattern, teachers ' teaching capacity is temporally and spatially all limited with the flexibility that gives lessons
System, Traditional Classroom is mainly lectured with the active of teacher and with the dependent response of student as principal character, teacher often focuses on leading to
The telling about with the implantation of behavior teaching for knowledge is realized of language is crossed, the leading position tendency of teacher is projected in teaching process,
And students' ethics are habitually ignored.
Traditional classroom instruction requires student classroom notice high concentration, often it is difficult to accomplish, and the difficulty of class offerings
Point also is difficult to disposably grasp by the teaching in classroom, and student and necessary and teacher are synchronous in time, synchronous in thinking, just meeting
Preferable results of learning are obtained, simultaneously because spatiotemporal constraint, the content of courses is very restricted, exchanges and communication
It is very limited amount of.
Classroom instruction under this teaching pattern is often excessively inflexible, has not only fettered enthusiasm, the master of Students ' Learning
Dynamic property and creative performance, also add teachers ' teaching difficulty, reduce the efficiency of teachers ' teaching.While traditional teaching mould
Formula does not possess specific aim, it is impossible to realize the asynchronous of learning aid, and content abstraction and doctrine are not easy to student's understanding and absorption.
So needing a kind of new teaching pattern to overcome above-mentioned deficiency, efficiency of teaching is lifted.
How high no matter these common terminal devices of PC, configure, and its resource is limited all the time；For
Teacher wants to complete the computing of a complicated math equation sequence formula when giving lessons, or the project of an experiment simulation with
And the process of 3-D view, if processed in common PC, estimate time-consuming a couple of days or even the time of several years, and
General user can not possibly be equipped with one " computer of milky way level " for oneself；The large-scale development such as such as CAD, UG is not only
Unit mandate price be up to tens thousand of units, and carry out every time install configuration all very expend the time,
The long-distance education of early stage using teach by correspondence and radio and television by the way of, it is mutual that the feature of its one-way transmission can not meet modern teaching
Dynamic demand.Simultaneously because the high speed development of field of information networks, the appearance of network distance instruction mode has carried front institute
Not some Teaching Experiences, the access mode that it possesses is flexible, knowledge dissemination is rapid, resource-sharing the features such as, can not only pass
Very big booster action can be also played in system teaching, greatly be compensate for the deficiency in conventional teaching, also promised to be following religion
The important educational pattern that learns.
