Description
Technical field
The present invention relates to teaching aid technical field, specially a kind of teaching automatic blackboard cleaning device.
Background technology
Teaching aid, when student being enable intuitively, visually to understand each appliances used in the content of courses and teachers' instruction
The general name of the apparatus used.Teaching aid is referred to as.The learning interest of student can be improved in teaching aid, enriches perceptual knowledge, and help forms clear
Concept, the observation ability and thinking ability of Developing Students '.Generally divide common teaching aid, special teaching aid, 3 class of Teachig-aid for infant studying.
Common teaching aid：Including conventional used in middle and primary schools' basic education and big, all kinds of specialized educations of special secondary school and profession religion
Tool.Generally there is material object, objective things is directly presented in face of student, so as to student's direct feeling；Object simulating, including mark
Originally, model and other duplicate, such as tellurion, manikin, engineering equipment model；Describe the chart of things image, including
The various visualization charts such as picture, photo, map and statistics, design；The sophisticated equipment of things image and its process is reproduced, such as
Projector, television set, recorder, video recorder, slide projector, projecting apparatus etc..The conventional teaching aid used when also giving lessons, as blackboard,
Blackboard eraser, blank, chalk etc..
Special teaching aid：The disabled persons and mentally retarded child etc. such as example blind to special education object, deaf, mute are generally referred to impart knowledge to students
Special implement used.Common special teaching aid has blind person's plate, scotograph, hearing aid, typoscope etc..
Teachig-aid for infant studying：For toy, intellectual development articles for use used in preschool child's formative education.The fortune of child can be developed
Kinetic force, its consciousness of training, excites its imagination, arouses its curiosity.Teachig-aid for infant studying is provided for the physical and mental development of children
Material conditions, including intuitive picture, image, technology, split, meccano, building, structural model, musical sounding toy etc..
Blackboard, before word invention, it has been found that charcoal can draw a picture, and can be sent out in some ancient times grottos in Europe
Some mural paintings in existing ancient times, the palisades for drawing these mural paintings have been properly termed as blackboard from traditional sense.
Ancient Chinese teaching be mostly used a kind of article referred to as sand table, with hardwood on sandy soil repeated writing, but because sand
Soil is softness, it can not be interpreted as being a kind of blackboard.
Middle Ages, it has been found that lime is mixed and made into block with water, with the method similar to charcoal pencil dark hard
Article surface write, to 19th century, people are coated in board surface with pitch-dark, to protect plank not to be etched, certainly at that time
The main function of blackboard not be teaching, until 19th century mid-term just all over the world, school comes into vogue.
Over more than 200 years, blackboard is applied to plank, the hard objects such as cement surface, to 90 from earliest with blacking
The water mill glass in age, color coated steel sheet, composite panel ... have witnessed the development step by step of world's educational undertaking, are passed for the mankind
Knowledge is broadcast, spreads education, has made distinctions won on the battlefield.The type of existing blackboard also begins to become complicated various, point has from color black
Plate, green plate, blank ... divides from surface shape surface plate, cambered plate, and dividing from structure composition has holder movable plate, pushes and pulls
Plate, lifter plate, magnet board point have blackboard for education from purposes, blank of handling official business, billboard, display board .. and blackboard for education
There are electronic blackboard, Multifunctional combined board, combination push-and-pull blackboard, interactive electric whiteboard, band curtain projection plate etc..
Blackboard is a kind of modern teaching field commonly teaching aid.Blackboard is not the plate face for refering in particular to black, traditional sense
On say it be one can use chalk repeated writing plane, plate face is hard, is chiefly used in imparting knowledge to students.Blackboard generally uses plank or frosted
Made of glass etc., it can be write above with the specific writing material such as chalk.Mostly black, blackish green, white or cream colour
Color.
Blackboard after use, needs wiped clean again, so that next time is continuing with, still, traditional blackboard-cleaning side
Formula is artificial directly wiping, this wiping method, and since human body is close to blackboard, a large amount of dust generated in wiping process can make dirty
The body and clothes of people, while a large amount of dust can be directly sucked in by human body, influence the health of human body.
