Video materials is developed for teacher equally also very tired, generally, develop a subject, need recording to present briefly and succinctly, construe, multiple mode of learning such as exam pool explanation, knowledge point is repeatedly combined again and again, is split, is combined, and then defines again and reaches the dozens of minutes even video of hundreds of minute one by one.
Be directed to the problems referred to above, also starting have many teachers to attempt at present adopts new mode to solve these problems, such as comparatively popular at present micro-video teaching, several knowledge point is together in series by instructor, and the instructional video forming about seven minutes is one by one selected on demand for learner.Although the organizational form that the method compares the video teaching resources of the first generation has had scientific progress, its logicality and bulking property poor, be generally only suitable for for Art undergraduate, but for organization system natural sciences study still more difficult realization.
And then, the design also integrated design often of learning machine, merge mutually by learning machine and various module, or a lot of sections object learning content is placed on desultorily for learners' corpora selection in learning machine, or be exactly that a learning machine only carries out for one or a small amount of subject.Although the former saves cost, but the renewal of its learned lesson is owing to mostly being free renewal, so the enthusiasm of developer is not high, although the latter has looked after the enthusiasm of course developer, but release in the face of new course and then need to change whole learning machine, the cost that learner pays is high.
For this, also have some learning machines to release at present and adopt the mode of learning card to carry out renewals sale, but due to learning card capacity little, or confidentiality is poor, is unfavorable for large-scale popularization.
