Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to skeletal muscle and coordinates dynamic demonstration device.
Background technology
Along with going deep into of classroom instruction reform, the multimedia effect be used in teaching becomes increasingly conspicuous.But at vast rural middle school, multimedia can not spread to each classroom, the configuration of audiovisual aids is also very limited.Biological subject is the combination of natural science and the humanities, have a wide range of knowlege, spatial impression by force, a lot of problem is more abstract.The shortage of audiovisual aids, manyly cannot directly the biological phenomenon of perception, the biological things that is difficult to remember make to be at a loss what to do during Students ' Learning and helplessly even feel more uninteresting, allows many students lose interest to biology Class, thus makes the teaching of biology Class be absorbed in deadlock.
Under Background of New Curriculum, what bioconversion medium was focused on is the validity of classroom instruction.The validity mainly Teaching Effectively of teacher of the giving advice and effective study of student of classroom instruction.The core of Teaching Effectively is effective study of student, and the prerequisite of effectively study is the Teaching Effectively of teacher.Therefore, the key of classroom Teaching Effectively is the Teaching Effectively of teacher.Whether teaching is effective, is not perhaps taught conscientiously half-hearted in whether teacher of the giving advice has taught, and refers to whether student acquires what or student is well bad.If not teaching students in accordance with their aptitude of " suiting the remedy to the case ", even if it is also invalid teaching that teacher teaches very arduous.As can be seen here, Teaching Effectively depends on teacher on classroom for student provides the effective information of " making to measure ".
The material source of self-control biology teaching aid is in life, cost is lower, it is easy, simple to make, teacher, student gather materials on the spot, the biology teaching aid aided education of doing it yourself to make can reach teaching efficiency directly perceived, vivid, lively, interesting equally, student can be attracted, also mitigate the difficulty of teacher in teaching, improve the efficiency of teaching of every class; Very practical in the teaching of biological lesson of middle school hall, be instrument capable in bioconversion medium, the present situation that teaching instrument and equipment lacks can be solved to a great extent.
Summary of the invention
The purpose of this utility model to provide exactly a kind of cost lower, make easy, simple, can reach intuitively at teaching process, the skeletal muscle of vivid, lively, interesting teaching efficiency coordinates dynamic demonstration device.
The utility model is achieved through the following technical solutions:
Skeletal muscle coordinates dynamic demonstration device, comprise the first ruler 1, second ruler 2, first rubber tube 3 second rubber tube 4, articulated elements 5, first fixture 6 and the second fixture 7, it is characterized in that: it is hinged that the first described ruler 1 and the first ruler 2 pass through articulated elements 5, first rubber tube 3 and second rubber tube 4 one end fixed by first fixture 6, and first rubber tube 3 and second rubber tube 4 other end fixed by the second fixture 7.
The length of the first described rubber tube 3 is less than the second rubber tube 4 length.
The first described ruler 1 tail end bottom center is provided with groove 8, and the second rubber tube 4 is fixing in groove 8.
The first described rubber tube 3 tensile elongation is less than length when the first ruler 1 and the second ruler 2 angle are 180 ° between the first fixture 6 and the second fixture 7.
The second described rubber tube 4 tensile elongation is less than the length of the first fixture 6 and the second fixture 7 length sum when the first ruler 1 and the second ruler 2 angle are 0 °.
Compared with prior art, the beneficial effects of the utility model are:
The teaching aid of the article assembled configuration complexity come pinched at one's side conveniently by the first ruler 1, second ruler 2, first rubber tube 3 second rubber tube 4, articulated elements 5, first fixture 6 and the second fixture 7 etc. that the utility model provides, compared with experimental facilities in the past, reach material and be easy to get, make simply.And in daily experiment, this teaching aid can use continuously, structure is simple, can use popularization on a large scale, and when the utility model is tested with it, interest can be strengthened, fascinating effect can be produced, this set up situation, bring out problem, extend expand, the method for introducing new class can reduce knowledge difficulty on teaching material, strengthens the presentation process that the teaching efficiency of this class is vivid, make whole teaching process Be very effective, greatly facilitate the aspiration to knowledge of student's Scientific exploration.
The beneficial effects of the utility model are: material source is in life, cost is lower, it is easy, simple to make, teacher, student gather materials on the spot, the biology teaching aid aided education of doing it yourself to make can reach teaching efficiency directly perceived, vivid, lively, interesting equally, student can be attracted, also mitigate the difficulty of teacher in teaching, improve the efficiency of teaching of every class.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
In figure: the first ruler 1, second ruler 2, first rubber tube 3 second rubber tube 4, articulated elements 5, first fixture 6, second fixture 7, groove 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Skeletal muscle coordinates dynamic demonstration device, comprises the first ruler 1, second ruler 2, first rubber tube 3 second rubber tube 4, articulated elements 5, first fixture 6, second fixture 7 and groove 8.
As shown in Figure 1, wherein the first ruler 1 and the first ruler 2 hinged by articulated elements 5, first rubber tube 3 and second rubber tube 4 one end fixed by the first fixture 6, and first rubber tube 3 and second rubber tube 4 other end fixed by the second fixture 7.
Wherein the length of the first rubber tube 3 is less than the second rubber tube 4 length.
Wherein the first ruler 1 tail end bottom center is provided with groove 8, and the second rubber tube 4 is fixing in groove 8.
Wherein the first rubber tube 3 tensile elongation is less than length when the first ruler 1 and the second ruler 2 angle are 180 ° between the first fixture 6 and the second fixture 7.
Wherein the second rubber tube 4 tensile elongation is less than the length of the first fixture 6 and the second fixture 7 length sum when the first ruler 1 and the second ruler 2 angle are 0 °.
The utility model is when specifically using, the situation of skeletal muscle cooperation is demonstrated, when the angle wherein between the first ruler 1 and the second ruler 2 reduces, when representing elbow in the wrong by the angle changed between the first ruler 1 and the second ruler 2, the bicipital muscle of arm shrinks, triceps muscle of arm diastole; Angle between the first ruler 1 and the second ruler 2 magnifies to time straight, and when elbow is stretched in expression, the triceps muscle of arm shrinks, bicipital muscle of arm diastole.
