Description

A kind of English teaching multimedia blackboard
Technical field
The utility model relates to English teaching aid field, specifically a kind of English teaching multimedia blackboard.
Background technology
English, a class of languages curricula, has obvious difference with other courses.It is as one way of life technical ability, more it is emphasised that listen, say, the ability of reading and writing, emphasis be application.Arrive the English teaching of university's advanced stage especially, more should jump out from the elementary teachings such as letter, spelling, grammer, expand and put into practice diversified teaching means, teach through lively activities, emphasis is shifted to the dialogue aspect of practicality gradually, the technical ability that could really help student the achievement of Curriculum Standards for English to be converted into its own existence and development, the raising of auxiliary each side quality.
To achieve these goals, in the classroom teaching of many universities, MCAI is widely used, and this is filled with fresh blood to classroom teaching reform undoubtedly.Use multimedia technology to comprehensive treatment capability and powerful interactive feature thereof such as text, sound, image, animations, establishment courseware CAI, abstract, uninteresting learning content are transformed into dynamic content that is image, interesting, visual, that can listen, both pictures and texts are excellent, very impressive vivid Teaching Circumstances to create one, motivate students' interest in learning, the learning initiative of mobilizing students.Reasonable utilization MCAI brings the leap of " geometry level " can to classroom teaching in efficiency, but, deliberately pursue modernization, use multimedia too much, the English class has just become multimedia show class, and teacher has just become " projectionist ", will bring the consequence had too much of a good thing.In the process of MCAI, teacher must play its leading role.English is the language subject that a practicality is very strong, must by between teachers and students, between student with student a large amount of carry out in English exchange, could training student English communicative ability.Multimedia plays teaching aided function, instead of substitution effect, in teaching, preferably multimedia teaching and conventional teaching instrument and means are combined, the featured function of multimedia teaching can be retained, the dominant role of teacher in teaching and status can be respected fully again, utilize Traditional teaching means to carry out the assurance of emphasis and the anatomy of difficult point.
But the teaching facilities in existing daily classroom and teaching aid, generally all be only applicable to traditional hall award, the multi-media classroom arranged separately is enabled in multimedia teaching usually, the two can only be used alone, the instruction of teacher is separated with multimedia application, is unfavorable for the combination of teacher for two kinds of teaching patterns.And design multimedia function being incorporated into classroom of minority, often can only comprise video, audio frequency, projection etc. one of them, multimedia teaching demand can not be covered comprehensively, still cannot realize impart knowledge to students variation.
In addition, no matter in multimedia teaching or in traditional writing on the blackboard hall is awarded, arranging of the teaching such as blackboard, projection screen and display exhibition facilities is usually all fixing, due to the reflective phenomenon that morning and evening light refraction angle causes more greatly, and the problem such as the fixing plane student that cannot take into account the front-seat edge in the classroom teaching blind area of causing exists always, be left in the basket for a long time and effectively do not solved, greatly affecting learning efficiency and learning quality.
