Description
Technical field
The utility model relates to a kind of history teaching aid, belongs to teaching aid technical field.
Background technology
Teaching aid is exactly can so as to the apparatus of aided education activity in teaching process, and teaching aid can strengthen the learning efficiency of student, the efficiency of giving lessons of teacher.History, be a subject of the historical events recording and explain series of human active process, history gives wisdom, religion people goes to treat in the past with the deep eye with history depth feelings, now, in the future, and not limit to by the ground of heart at the moment, be unlikely to become shortsighted an ordinary class of person.Only have and be profoundly familiar with in the past, could understand all of generation now, just contribute to selection correct way forward, just can represent fine future, history is not so-called " old fogey " in some human eyes.History is that Chang Xuechang is new.The responsibility of historian not restores history simply, but constantly makes new explanation to history, for providing the foot " mirror that money is used for reference the present age.
Be main teaching aid with textbook substantially in historical teaching, this type of single teaching is difficult to the interest mentioning students, and historical content is a lot, upper and lower 5000 of so-called China, single only one China just has a very long historical floods, add external still more, if the summary mnemonics of neither one entirety more than content, students is easy to lose interest and even loses the confidence.And each test is all single question-answering mode, student is caused to conflict psychology.
For this series of problems, patent No. CN201420542102.1 has innovated a kind of history teaching aid.But still existing defects, exposed answer makes the thinking that student cannot be complete, and recall, thinking is restricted, and this utility model cannot be illustrated in any place on blackboard owing to only having the through hole at top, chassis, large by limitation.
Summary of the invention
For solving the problem, the utility model proposes a kind of history teaching aid.
A kind of history teaching aid,: comprise chassis, comprise the lid be arranged on chassis, described chassis is provided with some concentric circless, described concentric circles is decorated with some equidistant black scrobicula diameter lines, described lid is provided with the concentric circles with chassis equal number, the circle in described lid bosom is set to transparent and edge non-notch, remainder be set to opaque, and have equidistant breach between two diameter lines corresponding with chassis, be provided with circular slide rail between every two concentric circless of described lid, and there is a certain size friction force.
Further, be provided with central shaft in the middle of described chassis and described lid, described central shaft is provided with fixed screw.
Further, described tray bottom is provided with magnet, and top is provided with through hole.
Further, the supporting card having respective shapes in described chassis.
The utility model compared with prior art, it has following beneficial effect: history teaching aid of the present utility model, tray bottom is provided with magnet in use, any corner on magnetic blackboard can be close to, one through hole is arranged at top, this utility model can be hung over independently consulting for students, remembering somewhere of classroom by the time after school, improves learning efficiency.The central shaft of chassis and lid centre is provided with fixed screw, for fixed cover, lid can be taken away when being suspended on classroom or changing card, when testing, lid is covered, only give student's key word, not with Option Form test student, the answer covered gives student enough thinking spaces, play memory and imagination, thinking is taken exercise, each concentric circles of chassis is divided into equidistantly fan-shaped, the same historical content of fan-shaped displaying that two adjacent same radius surround, from inside to outside step by step deeply, the breach of lid just can represent the fan-shaped content of a slice on chassis, circular slide rail is provided with between every two concentric circless of lid, can relative sliding, the content that can represent the circle of the one the second exactly covers the 3rd concentric circles content simultaneously, lid does not rotate in the absence of external forces to have certain friction force to ensure between slide rail and lid.
