Description
Technical field
The utility model relates to a kind of Teaching aid for electricity that is used for Experiments of Electricity.
Background technology
At present in nature study and the junior middle school physics teaching, relevant Experiments of Electricity are that the teacher is by experiment content mostly, used experiment components and parts are placed on the dais operate, demonstration is seen to the student, though this demenstration method is more directly perceived, when class demonstration, plane, place, dais is parallel with student's sight line, therefore the Most students method of attachment that can not see circuit clearly, simultaneously the student can not with teacher's operation that experimentizes synchronously.Find by long-term teaching practice, this passive form of teaching is difficult for motivating students' interest in learning, can't make the student participate in experiment in person, also be not easy to simultaneously teacher's explanation, promptly influenced teaching process, do not reach desirable teaching efficiency again, be unfavorable for the cultivation of student's independent operation technical ability and the exploitation of early stage innovation technical ability simultaneously yet.In order to motivate students' interest in learning, make each student can both take action on one's own to participate in the experiment, improve student's the ability that uses one's hands and brains, be convenient to the student and understand circuit intuitively, grasp the circuit rudimental knowledge, Chinese patent discloses a kind of " combined appliance for teaching electricity " (application number is 98226515.8) on March 1st, 2000, it is made up of experiment base plate and various teaching aid part, on the plane experiment base plate many equidistant in length and breadth protruding buttons are arranged, various teaching aid parts are made up of buckle loam cake and buckle lower cover, there is the protruding button of metal at buckle loam cake two ends, there is recessed button at two ends, buckle lower end, and various buckles can be easily by protruding the buckling that is pressed on the experiment base plate.Though this teaching aid can satisfy junior physics experiment problem, also can be used as the movable equipment in the student second classroom, but because its making is complicated, cost is high, the while can not be demonstrated immediately and be checked the experiment content of learning, and makes this teaching aid popularize in middle and elementary school student and is subjected to certain limitation.
Summary of the invention
The purpose of this utility model provide a kind of directly perceived, be convenient to the Experiments of Electricity teaching aid of imparting knowledge to students, can be convenient for carrying.
For achieving the above object, Teaching aid for electricity of the present utility model comprises demonstration board, identification piece, connection lead, and demonstration board is an accordion structure, and demonstration board is provided with many windings terminal, identification piece be connected lead and be connected with binding post respectively.
Above-mentioned demonstration board is three folding foldable structures, and wherein a fold plane is a blackboard surface, and other two fold planes are demonstration face, and are hinged between each fold plane.
Above-mentioned every winding terminal is made up of two or three binding posts, to be fit to grafting or to articulate corresponding identification piece.
Offer the connecting hole that matches with binding post on the above-mentioned identification piece, and in its front or the two sides paste (or describing) various electricity components and parts figures arranged.
After adopting the structure of this design, the utility model not only can make the student participate in Experiments of Electricity in person in physics teaching, and can with teacher's operation that experimentizes synchronously, and processing ease, take action on one's own by the student, can make student's intensification further understanding and understanding in the interesting practice that uses one's hands and brains, help the student in preliminary acquisition electricity knowledge being gained knowledge, cultivation helps to improve the quality of teaching to the interest of electricity course.Characteristics such as the utility model can be demonstrated experiments such as all series parallel circuits of primary school, junior middle school's electromagnetics part, and can describe, check and consolidate the experiment content of learning by small blackboard easily, and it is wide to have an experiment content, and structure is visual in image.In addition because the utility model is designed to folding structure, have easy to carry, save advantages such as material, cost are low, be fit to China's national situation, be convenient to popularize and use in middle and primary schools.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Be that embodiment is further described the utility model below with the accompanying drawing:
Be illustrated as and be used for a specific embodiment of the present utility model, the three-ply board that three block sizes are moderate (scale board or other light sheet material) is connected to each other the three folding foldable structures that formation can be convenient for carrying with hinge, wherein a blacking is used as blackboard surface 2, interconnective in addition two as demonstration board face 1, many group metal connection posts 3 are installed on demonstration board face 1, every winding terminal 3 is two or three, various identification pieces 4 are identical with the demonstration board material therefor, and offer the spliced eye that matches with binding post 3 thereon, various identification piece 4 sizes and shape are made its grafting (or articulating) seem to the binding post 3 suitable dimensions and shape respectively, paste (or describing) various electricity components and parts figure on its surface respectively, and near respective connecting, mark "+", "-" utmost point.For distinguishing live wire, ground wire and zero line, will connect lead and be distinguished with red, black, yellow three kinds of colors, connecting lead can be respectively in 3 installation and removal arbitrarily of each winding terminal.
The utility model can make student's staff one cover, launch during use, set level or hang, the identification piece of describing or be pasted with components and parts figures such as reometer, voltage table, resistance, electric capacity, power supply, switch, small electric bulb, motor, magnet, coil, diode, three utmost points 4 that experiment is required is pegged graft or is articulated on the suitable binding post 3, connect and compose the loop by the experiment content requirement with the connection lead of respective color then, promptly finish desired experiment content.Experiment finishes, and can corresponding circuit diagram be depicted on the small blackboard face 2 that is connected with demonstration face 1, thereby help to enhance memory and understand impinging upon the experiment of being done on the demonstration face 1.Find that by teaching practice the utility model is a kind of electricity ushered-in education demonstration and operates indispensable desirable teaching and schooling apparatus.
