How to effectively cultivate the spatial imagination of primary school students

Cultivating Imagination:

1. Enrich children's life experience and develop children's appearance;

2. Provide children with a suitable environment to stimulate children's desire to imagine;

3. Give children a relaxed atmosphere and encourage them to express their imagination;

4. Encourage children to imagine boldly and guide children to fantasize reasonably;

5. Cultivate the good psychological quality of discovering and raising problems;

6. Participate in creative activities and cultivate correct fantasies.

1. Strengthen the teaching of picture recognition.

As the saying goes, knowledge is in practice. Facts have proved that giving full play to the visual and tactile functions of people is conducive to the formation of students' sense of space. When observing the model, students are asked to look at it from all angles, touch and feel it with their hands, and ask students to name the characteristics of the geometric figure being observed in combination with the figure.

Models in stereo geometry are divided into physical models and teaching aid models. The walls, corner lines, desks, chalk boxes, textbooks, etc. in the classroom are all good models. These things are easy to use and can be operated by students, which is conducive to students' understanding of what they have learned, and at the same time can play a role in adjusting the classroom atmosphere and relieving learning pressure.

However, some knowledge cannot be found in real life, so it is necessary to use teaching aid models, or teachers to make some models.

2. Pay attention to practical activities such as observation and operation of objects and models.

It is an important way to cultivate spatial imagination ability by paying attention to the observation, dissection and analysis of objects and models, and carrying out practical activities such as model making, measurement, and visiting.

According to the characteristics of spatial graphics, guiding students to find the corresponding solid model is an effective method to cultivate students' observation and imagination ability, and it is also an important means to enable students to finally get rid of the model for spatial graphics analysis and imagination. For example, three, think of graphics.

Thinking about the image, that is, in the process of imagination, it does not rely on models and intuitive diagrams to help thinking, but can process the memory of spatial shapes in the mind according to needs to create new spatial shapes. Materialize into a geometric model, and then figure out the relationship between the parts of the shape, so that you can still reproduce the geometry in your brain with your eyes closed. In teaching, first combine the model, look at the intuitive diagram, and then let the students gradually break away from the model and directly look at the intuitive diagram to solve the problem.

Fourth, with the help of modern teaching equipment.

The use of multi-** teaching can make the teaching content abstract into concrete, which is convenient for students to observe and understand, and is conducive to students' understanding and mastery of the teaching materials. Teachers can make courseware according to the needs of teaching, and make graphics through the dynamic presentation of the computer'Live'Let students observe graphics from different angles, so as to achieve a deep understanding of abstract theoretical knowledge and cultivate students' spatial imagination ability.

We all know that imagination is the source of creativity, and the cultivation of spatial imagination ability is not achieved overnight, in this regard, we can not be in a hurry, accustomed to overstepping, to leave time and space for students' imagination, can not always be afraid of delaying time. In the past, in teaching, when students couldn't solve it, they couldn't help but want to talk about it, such as problems related to folding, and talked a lot, but as a result, they got twice the result with half the effort, and they were not lightly tired, but the students' abilities were not improved. Later, I let myself be "lazy" and let the students explore the corresponding changes before and after the folding of the figure by themselves, which achieved better results.

Whether it is in study or work, everyone must be no stranger to **, Lianhu can cultivate our ability to think independently and innovate through **writing. What kind of ** have you seen? The following is how to cultivate students' spatial imagination for you, welcome you to learn from and reference, I hope it will be helpful to you.

Object Teaching Multi-** Teaching Digital Camera Projector.

[**Abstract.]

Spatial cognitive ability, three-dimensional thinking ability and drawing skills are the key to learning to make a good drawing, in order to let students improve their spatial thinking ability, the use of physical teaching, multi-class teaching, intensive exercises, in a variety of teaching methods targeted at the teaching is easy to ignore some problems, for example, the projector is not only an indispensable tool for multi-body teaching, but also a practical projection equipment. In addition, the digital camera can also illuminate a certain flat projection, which is of great help to students with poor spatial imagination.

Mechanical Drawing" is the current vocational and technical school teachers and students generally reflect the more difficult course, the difficulty of the course is the cultivation of students' drawing and drawing skills, in the complex three-dimensional transformation into the plane and the plane into three-dimensional spatial understanding, three-dimensional thinking activities, most of the students are difficult to adapt to the situation. So, what are the key factors that should be solved in teaching in order to effectively cultivate students' spatial cognition ability, three-dimensional thinking ability and drawing skills? I will talk about this issue mainly from three aspects:

1. Object teaching

Physical teaching is to learn to use models, objects, wall charts and other intuitive image teaching methods in the teaching of drawing, to guide students to use the law of projection to understand the relationship between objects and graphics, so that the projection elements can be clearly impressed in the minds of students, which can effectively cultivate students' spatial imagination ability, and receive twice the teaching effect with half the effort. In teaching, let students see more views of some simple basic geometric bodies, such as rectangles, prisms, cylinders, and cones, and through the understanding of graphics, they are familiar with the spatial shapes corresponding to these views, so as to realize the transformation of thinking from plane to space, and can also help students learn to decompose complex views into simple figures, so as to improve their spatial imagination ability. In drawing, there are many shapes with holes and keyways on the surface, and there are other various structures inside, so it is indeed difficult to draw a view by imagination at the beginning of the course, and the model is a better means at this time.

With intuitive models as teaching aids and proper explanations, drawing becomes much easier. For example, in the section where students tend to confuse the cross-sectional view with the cross-sectional view, the model is used to draw cross-sectional lines on the disconnected parts, so that the difference between the cross-section and the cross-sectional view is clear at a glance, and the difficulty of learning is reduced.
