Description

Document and model collection rack for mathematics teaching

technical field

The utility model relates to a mathematics teaching appliance, in particular to a device for collecting mathematics teaching models and documents.

Background technique

In mathematics teaching, we often have the experience that students can understand clearly in class, but they can't do homework after class. Why is this? The reason is: students just listen to mathematics, but do not do mathematics, that is to say, they do not pay attention to the learning process. In the current teaching, many teachers do not pay enough attention to the learning process of students. They always go straight to the topic, thinking that the teaching purpose can be achieved by letting students master a few knowledge points, ignoring the experience and exploration process of knowledge, and ignoring the relationship between students. The process of communication and cooperation between students also ignores the emotional teaching method of students. This kind of teaching leads to single and passive learning methods for students, and there are not many opportunities for independent exploration, cooperative learning, and independent acquisition of knowledge. If things go on like this, teachers will struggle to teach, students will struggle to learn, and it will be difficult for students to improve their academic performance. In order to improve the teaching effect of mathematics, teachers need to use a large number of teaching documents and mathematical models to facilitate students' understanding.

The history of mathematical models can be traced back to the era when humans began to use numbers. As humans use numbers, they continue to build various mathematical models to solve various practical problems. Establishing a mathematical model is an indispensable bridge to communicate the connection between the actual problems in front of you and the mathematical tools.

Mathematics teaching documents need to determine the appropriate teaching starting point and end point according to the teaching objects and teaching objectives, and arrange the teaching elements in an orderly and optimized manner to form a teaching plan document. It is a science that uses systematic methods to scientifically solve teaching problems. It aims at optimizing teaching effects and solving teaching problems. Specifically, teaching documents should include the following teaching design contents: First, teaching design transforms teaching principles into teaching materials and plans for teaching activities. It must follow the basic laws of the teaching process, choose teaching objectives, and solve the problem of what to teach. Second, instructional design is a planning and decision-making activity to achieve teaching goals. Instructional design, in the form of planning and layout arrangements, makes creative decisions about how to achieve teaching goals to solve the problem of how to teach. Third, instructional design is guided by a systematic approach. Instructional design regards each element of teaching as a system, analyzes teaching problems and needs, establishes a program outline for solving them, and optimizes teaching effects. Fourth, instructional design is a technical process that improves the efficiency and interest of learners in acquiring knowledge and skills. Instructional design is an integral part of educational technology, and its function is to use a systematic approach to design the teaching process, making it an operational program.

In the teaching process, mathematics teachers need to use model teaching aids such as geometric models and function curve demonstration boards, as well as teaching documents such as teaching plans and wall charts, so that students can fully understand what they are learning. When teaching, it is inconvenient for the teacher to carry model teaching aids and teaching documents alone; at the same time, when teaching, the teacher also needs to lift the model with his hands to show it to the students, which is very inconvenient; for some teaching aids such as teaching function curve demonstration boards, It is also not convenient to hang.

Utility model content

The utility model provides documents and model collection racks for mathematics teaching. The utility model solves the problems that it is inconvenient for teachers to carry model teaching aids and teaching documents in the process of mathematics teaching; it is inconvenient to display mathematics teaching models; it is inconvenient to hang teaching function curve demonstration boards. .

In order to solve the above problems, the utility model adopts the following technical solutions: the collection rack for documents and models used in mathematics teaching includes a collection box 1, the collection box 1 is a rectangular box-shaped body, and there is a model collection bin with an opening facing upwards in the collection box 1 2 and the file collection bin 3; the four corners of the model collection bin 2 are respectively vertically fixed with sleeves 4, and each sleeve 4 is inserted with a telescopic pull rod 7, and there is a slideway 12 on the telescopic pull rod 7 along the length direction , there is an arc-shaped groove 11 at the lower end of the slideway 12, and a fixer 9 is fixed on the upper side of the casing 4, and a fixed sphere and a spring assembly 10 are arranged in the fixer 9, and the fixed sphere is slidingly matched with the slideway 12; A support cover 5 is fixed on the upper end of the telescopic pull rod 7, and a folded plate 6 is arranged above the support cover 5, and the folded plate 6 and the rear side of the support cover 5 form a folded connection structure through a hinge shaft 14; There is an elastic piece 8 on both sides, and there are fixed pins at both ends of the inner side of the elastic piece 8, and jacks 13 are arranged at equal intervals on both sides of the support cover plate 5, and a fixed pin on the elastic piece 8 is fixedly connected to the folding plate 6 , Another fixing pin cooperates with a certain socket 13.

Mathematics teachers can place mathematical models in the model collection bin, and place teaching plans, documents, demonstration boards and other materials in the file collection bin, which is convenient for collection and portability; during teaching, the support cover can be pulled up , when pulled to the limit position, the fixed sphere tops in the arc groove to fix the telescopic pull rod. At this time, the required mathematical model can be taken out, and the teacher's model can be placed on the support cover or folded plate for demonstration; the folded plate can also be Folding backwards, through the cooperation of the elastic sheet with different jacks, a triangular support structure is formed between the support cover, the folding plate and the elastic sheet, and teaching demonstration boards or wall charts can be hung on the folding board, which is convenient for teaching; after use Finally, firmly press down on the support cover, the spherical body will compress the spring, the telescopic pull rod will contract, and the support cover will move down. The utility model has a compact overall structure, can be used for teachers to demonstrate models in lectures, and provides convenience for teaching.

Detailed ways

The utility model is described in detail below with the best embodiment.

As shown in Figure 1-7, collection box 1, sleeve pipe 4, support cover plate 5, folding plate 6 are all plastic products, telescopic pull rod 7 is made of aluminum, so the weight is lighter.
