Description
Technical field
The present invention relates to teaching field, more particularly to a kind of instructional device and its application.
Background technology
Three-view diagram be observer from above, the left side, from positive three different angles same space geometric from and draw
Figure.The sight of people is defined as parallel projection line, object is then faced and looks over, the profile of finding object is thrown with positive
The figure that shadow method is drawn out is known as view.One object has six views：Regarding for gained is rearwards projected before object
Figure claims front view（Front view）--- it can reflect the preceding shapes of object, claim above object to the view obtained by following projection
Top view --- it can reflect shape above object, the view of projection gained claims left view from the left side of object to the right side（Side view
Figure）--- it can reflect the left side shape of object, also have other three views not to be in daily use.Three-view diagram is exactly front view（Face
Figure）, top view, left view（Side view）General name.Three-view diagram can correctly reflect the orthographic projection work of object length size
Cheng Tu（Front view, top view, three basic views of left view）For three-view diagram, this be engineering circles it is a kind of to geometry of objects about
Fixed custom into abstract expression mode.
Three-view diagram is senior middle school's compulsory course《Technology and design 1》Middle school student feel one of more difficult content.Often go out in teaching
Existing pupil drawing custom is bad, map field study when it is few, the conversion between space configuration and planar graph is had any problem, and in study
The problem of appearance and mode of learning etc..Being given birth into primitive Neo-Confucianism for three-view diagram be not strange, and student has contacted in Mathematics Curriculum,
Understand three-view diagram method for drafting.But student do not notice the three-view diagram of three-view diagram in mathematics and technical language have compared with
Big difference.Three-view diagram is mainly figure obtained by training of students from three azimuthal projection space configurations in mathematics, helps student's reason
Solution space structure and position relationship.Three-view diagram in technology " language " has many codes and standards sides as a kind of technical language
The content in face, is designer's design of expression thought and the one kind " language " for exchanging works information.Although the same into primitive reason,
It is that three-view diagram teaching in mathematics does not rise to the height of " language ", that is to say, that three-view diagram is as a kind of work for expressing exchange
Tool, student do not know.Student is more random when three-view diagram is drawn such as in mathematics, is less particular about specification.
It is relatively conventional in existing teaching three-view diagram method, it is teacher station at dais, multiaspect is lifted in a manner of hand-held
Body Model, such as triangular pyramids, when teacher lifts trigone cone, and the front view of trigone cone is shown to student, rectangle faces
Student Teachers, during corner angle alignment student because the seat that student sits is different, the shape seen be it is different, what right opposite was seen
For rectangle, its length of side is the length of side of trigone cone, but the rectangle length of side seen of both sides student is less than the triangular pyramid length of side,
When teacher shows the side view of trigone cone, the rectangle length of side that right opposite student is seen is the triangle of trigone cone
Height, but the rectangle length of side that both sides student sees is but high more than the triangle of trigone cone, and because because learning when showing
Raw seat is far and near different, it is impossible to intuitively it was observed that the specific difference of the so-called length of side described in teacher, causes to misread；This method
Greatly reduce the learning initiative of student, it is serious to even result in student and have a repugnance to learning three-view diagram, made for later teaching
Into serious consequence, and this method significantly increases the teaching difficulty of teacher, or even influences teaching process.
The content of the invention
For case above, the present invention solves teachers ' teaching inefficiency, consumes one's strength serious, students ' enthusiasm
It is not high, or even the problem of being weary of the course for learning three-view diagram is produced, the efficiency of teaching of teacher is greatly improved, improves student
Learning initiative, teach through lively activities, found in study it is happy, in happy mood learning.
