1. little, the small scale of scope.The general training content is a 1-2 teaching skill, meeting the trainee has only about 10, hours of instruction 10-15 minute, as Britain microteaching expert George Blang (G.Brown) said " it be one simplified, the teaching of segmentation, thereby make the student be easy to grasp ".
2. operation is arranged, but record.Microteaching generally carries out in little lattice classroom of simulation actual environment, and all processes are all produced by video camera.
3. feedback is arranged, can adjust.Connect the video recording that the trainee can watch oneself training, search one's heart and accept other people evaluation, in time adjust weak point.
4. may command can be imitated.Connect the teaching example video recording that the trainee could watch and imitate outstanding fugleman, perception and the various technical ability of understanding; Also can be from counselor's the direction that finds effort the discussion with classmates of commenting on.
5. almost be applicable to all teaching sights.
3. the technology essential factor of microteaching
◆ sight is simulated, is founded
◆ demonstration
◆ record
◆ playback
◆ feedback, evaluation
Along with the development of infotech, the tiny grid teaching system of digitizing, networking arises at the historic moment.All kinds of vocational and technical educations and various posies real training demand are growing, the development of qualified teachers' strength is difficult to meeting the market requirement on the one hand, on the other hand, in order to improve teaching efficiency, shorten the training cycle, need a kind of little lattice experience system that is adapted to modern network technology and vocational instruction characteristics of exploitation in a hurry.
