Description
Technical field
The utility model relates to teaching apparatus for mathematics, is specifically related to the device collecting mathematics education model and document.
Background technology
In mathematical education, we usually have such cognition: on classroom, student listens clear, and homework but can not do.Why does is this? reason is: student just listens mathematics, and does not have doing mathematics, does not that is pay attention to learning process.In current teaching, a lot of teacher pays little attention to the learning process of student, they are through theme always, think and allow the several knowledge point of students just reach teaching purpose, have ignored the experience to knowledge and heuristic process, have ignored the interchange between student, cooperative process, also have ignored the Sentimental teaching method of student.Such teaching causes Students ' Learning method single, passive, and the chance of autonomous exploration, cooperative learning, independent acquisition knowledge is few.If things go on like this, teacher teaches difficultly, and student learns painstaking, and the school grade of student is also just difficult to improve.In order to improve the teaching efficiency of mathematics, teacher needs to use a large amount of Teaching Documents and mathematical model, so that student understands.
The history of mathematical model can trace back to the epoch that the mankind bring into use numeral.Along with the mankind use numeral, just constantly set up various mathematical model, to solve various practical problems.Founding mathematical models links up the requisite bridge contacted between practical problems and mathematical tool of confronting.
Mathematical education document needs according to teaching object and instructional objective, and determine suitable teaching Origin And Destination, all key elements of imparting knowledge to students arrange in order, optimally, forms the file of teaching plan.It is the knowledge using systems approach science to solve problems in teaching, and it is for the purpose of teaching efficiency optimization, to solve problems in teaching for aim.Specifically, Teaching Document should comprise following Instructional Design content: the first, and Instructional Design is converted into the plan of teaching material and education activities element of instruction.It will follow the basic law of teaching process, selects instructional objective, to solve the problem of what being taught.The second, Instructional Design is the planned and policy-making activity realizing instructional objective.Instructional Design, with plan and the form of layout, carries out creationary decision-making to how just reaching instructional objective, how to teach problem to solve.3rd, Instructional Design is instruct with systems approach.Instructional Design regards a system as, analytic instruction problem and demand each key element of teaching, establishes the skeletal coding solved, makes teaching efficiency optimization.4th, Instructional Design improves learner's acquire knowledge, the efficiency of technical ability and the technical process of interest.Instructional Design is the ingredient of education skill, and its function is to use systems approach designed teaching process, makes it to become a kind of program with operability.
Mathematics teacher, in teaching process, needs to use as model teaching aids such as geometric model, function curve demonstration boards, also needs the teaching file such as teaching notes and wall chart simultaneously, student can be allowed like this to fully understand learnt content.When imparting knowledge to students, teacher one people carries model teaching aid and teaching file is very inconvenient; Meanwhile, when imparting knowledge to students, teacher also needs to hold pattern drawing high with hand, to show to student, very inconvenient; For teaching aids such as some teaching function curve demonstration boards, be also inconvenient to hang.
Utility model content
The utility model provides mathematical education document and model collecting frame, and the utility model solves teacher in mathematical education process and carries model teaching aid and teaching file inconvenience; Be not easy to show mathematics education model; Be not easy to hang the problems such as teaching function curve demonstration board.
For solving the problem, the utility model adopts following technical scheme: mathematical education document and model collecting frame, comprise disposable box 1, and described disposable box 1 is rectangular box-like body, has opening up model collecting bin 2 and collection of documents storehouse 3 in disposable box 1; Interior four Angle Position of model collecting bin 2 are vertically fixed with sleeve pipe 4 respectively, a telescopic lever 7 is inserted with in each sleeve pipe 4, telescopic lever 7 there is along its length a slideway 12, there is an arc groove 11 slideway 12 lower end, a fixator 9 is fixed with in sleeve pipe 4 upper side, have fixing spheroid and spring assembly 10 in fixator 9, fixing spheroid and slideway 12 are slidably matched; Be fixed with one piece four telescopic lever 7 upper ends and support cover plate 5, support cover plate 5 and be provided with one block of flap 6 above, flap 6 forms turnover type syndeton with support cover plate 5 back side edge by jointed shaft 14; A flexure strip 8 is respectively had in flap 6 both sides, inside flexure strip 8, there is fixed pin at two ends respectively, support that cover plate 5 both sides are equally spaced is provided with jack 13, a fixed pin on flexure strip 8 is fixedly connected on flap 6, another one fixed pin coordinates with a certain jack 13.
Mathematical model can be positioned in model collecting bin by mathematics teacher, is positioned in collection of documents storehouse by data such as teaching notes, document, demonstration boards, and so namely convenient collection, is easy to carry again; When imparting knowledge to students, support cover plate can be pulled upwardly, when moving extreme position to, fixing spheroid withstands in arc groove to be fixed telescopic lever, now can take out the mathematical model of needs, and tutor model is positioned over to support above cover plate or flap and demonstrates; Flap can also be rolled over backward, be coordinated from different jacks by flexure strip, make to support cover plate, between flap and flexure strip, form triangular support structure, can teaching demonstrating board or wall chart etc. are hung on flap, convenient teaching; After finishing using, firmly to pressing down supporting cover plate, spherical is by spring-compressed, and telescopic lever shrinks, and supports cover plate and moves down.The utility model compact overall structure, can be used for teacher's demonstrating model in lecture, for teaching provides convenient.
