Abstract

The utility model relates to a cross-extension demonstration device for historic knowledge, which is a dual-purpose instrument for teaching and learning, comprising a movable support which is made of plastic, aluminum, iron, wood and paper, a transverse rod, a rotating shaft and a paper roll. The utility model is assembled by small-sized component for being used as a learning appliance and can also be assembled as a large-sized component for being used as a teaching appliance, and the utility model can vertically lift, horizontally extend and crossing rotate for demonstrating systematic blackboard writing and knowledge. Therefore, the utility model can save the blackboard writing time in the class, increase the teaching and learning efficiency, lighten the teachers' labor intensity and avoid the invasion of chalk ash.

Description

Cross-extension demonstration device for historic knowledge

The utility model is a kind of dual-purpose instrument of imparting knowledge to students and learn.Before designing and producing this demonstration device, in historical subject, do not found corresponding demonstrating appliance.History teachers and student thereof have only books and historical map or atlas together, do not accompany with corresponding schooling apparatus and there is teaching aid.

For optimizing historical teaching and study, break the dull general layout of teachers and students in historical subject, overcome the limitation of conventional teaching method, exploitation student's intelligence, developing ability make it to study in order to practise, and are country's service of construction of modern, and design and produce this demonstration device.

The main part of this demonstration device is a travel(l)ing rest (figure one).Its base is made up of two width of cloth chiasma type base plates (1) and triangular support plate (2).Porose on it, it is porose a plurality of to adorn vertical beam (3) vertical beam two cover, can move up and down to intert horizontal bolt (4), is ordering porous symmetric form transverse slat (5) on the horizontal bolt, but move left and right then.The characteristics of this oscilaltion, move left and right are convenient to be provided with as required area of display.Its member has the model that varies in size.With the small members assembling, can do schooling apparatus.In the travel(l)ing rest that adopts large-scale component to make, draw high a cover vertical beam wherein, increase and insert horizontal bolt, transverse slat, load onto cross bar (8), screw (9), insert large-scale rotating shaft (6) and with the large-scale paper roll of systematic knowledge (7) teaching aid.Rotating shaft just can be as showing a film, each period each area or national legacy system show.Make the student carry out system's memorize from the globality of knowledge, guide look is received entirely, reaches in court the purpose that digests, grasps comprehensively, digests, and receives not to be that film surpasses the effect of film.(figure two)

Use this tool, can optimize historical teaching and study.It can melt integral body, system, comprehensively, relatively wait teaching and learning method in a stove, melt the teaching of Chinese history and world history and review in one, and the combination of implementation Chinese history and World History, carry out sync instruction and review, can make the student obtain comprehensive and systematic knowledge, can make in its knowledge of on microcosmic, grasping " point ", on macroscopic view, catch total rope of " line " and " face ", formation links work at selected spots with that in entire areas, well-regulated knowledge network.

Use this tool, can reveal from ancient times to the present history again by demonstration from top to bottom, thereby solve from top to bottom the blackboard writing on the blackboard and the contradiction of historical development order contrary from ancient times to the present, and can break through the restriction of blackboard, the continuity and the globality of maintenance knowledge and classroom structure.

Use this tool, carry out China and foreign countries' contrast, can implement education of the national conditions and ideological and political education effectively, melt intellectual, ideological content, scientific in one, make impart knowledge, tap intellectual resources, developing ability, the function of carrying out ideological and political education finds full expression, the qualified talent service of having both ability and political integrity for cultivation.

The knowledge of showing on the demonstration device is the systemic comprehensive knowledge of summarizing arrangement, have clue clear, have clear presentation, succinct smart wanting, characteristics such as understandable good note can make the historical events methodization of complexity.The knowledge systematize that disperses helps improving the memorize effect, helps the formation of temporal idea, spatial imagery, helps the exploitation of intelligence.

Use demonstration device, carry out polydirectional thinking activities, historical knowledge is carried out integral body understanding, both can accelerate the speed of imparting knowledge to students and reviewing, can improve in large area again and learn and quality of instruction.Through the grouping test, the student can digest basically in court.Nineteen ninety last issue, I student of arts class that appointed participates in provincial joint graduation examination, Historical Results is all passed, pass rate reaches 100%, the flat achievement of people reaches 83.9 fens, ranks among the best at Di Xian.

Claims

1, a kind of historical knowledge of utility model extends demonstration device in length and breadth, it is characterized in that described demonstration device is made of base (1), back up pad (2), vertical beam (3), horizontal bolt (4) and transverse slat (5), but be inserted in the oscilaltion of the cover of two on base porous symmetric form vertical beam, interspersed horizontal bolt, insert the movable transverse slat of porous symmetric form on the bolt, the travel(l)ing rest of block form, have rise and fall, about flexible, dexterity function easily.

2, demonstration device according to claim 1 is characterized in that said cross bar (8) is made of eight rectangular slot plates, is enclosed within on the transverse slat with screw (9), and the function that stretches about tool, terminal porose, can adorn rotating shaft.

3, demonstration device according to claim 1 is characterized in that said rotating shaft (6) by 12 hollow roundlet bar constructions, a pair of in twos connection paper roll, the function of tool rotation.

4, demonstration device according to claim 1 is characterized in that said paper roll (7) is made of the paper or the cloth of six width of cloth with systemic writing on the blackboard and knowledge, orders rotation demonstration in rotating shaft.
