A Mathematics Teaching Plotter

Abstract

The invention discloses a mathematical teaching plotter comprising a demonstration platform. A white board is arranged on the upper surface of the demonstration platform. A controller is arranged on the front surface of the demonstration platform. Three-dimensional plotting is transformed to two-dimensional plotting by adopting the structure of the demonstration platform, the white board and a fixing board so that the plotting difficulty can be greatly reduced for a teacher. The structure of a first column, a first rotating connector, a second column, an electric telescopic rod, a coiling cylinder, a first connecting rod, a second connecting rod and compasses is adopted so that the teacher can be assisted in instrumental fixing when a curve plotting is required, and thus plotting efficiency and then classroom efficiency can be enhanced. The structure of a video camera, a light lamp and a controller is adopted, the characteristic that the controller can be connected with a classroom multimedia system is utilized, and close-distance images photographed by the video camera are clearly and synchronously projected to the screen of a projector so that the students of all positions can clearly see the plotting steps of the teacher. The device is reasonable in design and better in effect in comparison with that of the conventional device.

Description

technical field [0001] The invention relates to the technical field of teaching plotters, in particular to a mathematics teaching plotter. Background technique [0002] With the continuous development of the world's scientific and technological level, people can't wait to improve the education model. The traditional education model advocates cramming and does not pay enough attention to students' actual understanding and mastery. In modern times, people began to pay attention to students' understanding, especially in mathematics. In general, inductive deduction is also called argumentation. As for the explanation of mathematical formulas and theorems, modern teachers are increasingly using deductive methods to help students understand them thoroughly.

[0002] With the continuous development of the world's scientific and technological level, people can't wait to improve the education model. The traditional education model advocates cramming and does not pay enough attention to students' actual understanding and mastery. In modern times, people began to pay attention to students' understanding, especially in mathematics. In general, inductive deduction is also called argumentation. As for the explanation of mathematical formulas and theorems, modern teachers are increasingly using deductive methods to help students understand them thoroughly. However, this method requires the assistance of a large number of equipment. Existing The advanced teaching plotter cannot meet more and more requirements. The position of the blackboard in the classroom is fixed, so it is difficult for the students in the back row of the classroom to see the teacher's deduction process clearly. Moreover, the volume of the drawing device is small, and it is difficult for the students to see clearly. In addition, it is difficult to fix the drawing device on the blackboard, and teachers need to hold it by hand, so the teaching effect will become very poor. Therefore, we propose a mathematics teaching plotter
