Description

Teaching aid for primary school mathematics statistics cognition teaching

Technical Field

The utility model belongs to the technical field of teaching aid technique and specifically relates to a teaching aid is used in cognitive teaching of primary school's mathematics statistics.

Background

The teaching aid is a model, a real object, a specimen, an instrument, a chart, a slide show and the like for explaining something, and comprises teaching equipment, a teaching instrument, practical training equipment, education equipment, experimental equipment, a teaching specimen, a teaching model and the like.

The research results of educational psychology show that students must convert the observation and contact of specific things into the perceptual knowledge irrelevant to the specific things and then convert the perceptual knowledge into abstract and generalized rational knowledge by means of sense in the initial stage of knowledge formation. The teaching aid is used as a teaching aid for teachers, has the irreplaceable effect of other means, enables students to understand teaching contents more visually and vividly, can mobilize the learning enthusiasm of the students, improves the learning interest of the students, enriches the perceptual cognition of the students, helps the students form clear concepts, and simultaneously cultivates the observation ability and the abstract thinking ability of the students.

In primary school mathematics teaching, the teaching aid is reasonably used, and the method is an important way for improving the primary school mathematics teaching quality. The students are placed in the main positions, the processes and inducements of the thinking elicitations of the students are grasped, wide thinking space and intelligence background are created, demonstration, operation and test opportunities are provided for the students as much as possible, the multidirectional thinking ability and the reverse thinking ability of the students are cultured, and the thinking ability and the creating ability of the students are developed greatly.

The difficult problem encountered in the traditional 'statistics' teaching: 1) the content of the teaching materials is too scattered, the emphasis is not clear, and the difficulty of lessons preparation is high. 2) The difficulty of the practical operation of the students is high. 3) The teaching material only takes city cases into consideration. Because children contact mathematics earlier, do not have abundant cognition to mathematics, the degree of difficulty is big in "statistics" cognitive process, and is slow, leads to many students think that mathematics study is very difficult, influences the study enthusiasm degree of student to mathematics.
