The Research On The Estimation Of Children In Primary School Students

The estimate is one kind universal and the widespread existence cognition processing process, regardless of the child or the adults must in the study or the life and its frequent contact. Although estimated that is very important to our daily activity is precisely in mathematics cognition process the great importance a part, however compared with in quantity ability other cognition aspect research, For example, actuarial, Jane count, add and subtract and so on, we estimated that the understanding of cognitive processing is still relatively poor and dispersed. At present in China there are many primary school teachers do not know the number of estimated capacity of pure meaning and importance; estimated net primary school capacity and awareness of how to develop estimates of the impact of factors which? How they affect the ability of primary and secondary school students is estimated net of development? Which training methods for different school-age children in more effective paragraph?In this study, estimated the number of lines in the form of tasks, to examine the number of children in primary schools is estimated that the capacity of line characteristics and estimated the level of Strategic Development to explore the capacity of the digital line is estimated that the impact of factors, and were carried out on the second year of the individual games within the hidden training methods to improve their enhance the understanding of the number of mental representation of symbols and the number of individuals outside the fourth grade, the estimated dominant strategy of training skills to improve their estimates, Finally, the task to change the form of digital lines is estimated to explore the four primary schools, sixth-grade children of different age stages of the vertical line segment in the estimated net number of tasks 0-1000 estimate the level and characteristics of the estimated capacity, to examine the estimated two-dimensional aspect to the task differences, and different age consistency of individual differences. The specific conclusion of the study are as follows:1. Line is estimated that the number of individual performance differences in a clear grade. Accuracy increased with the grade and higher estimate of the individual variables change with age. Characterization of the model number of the estimated age increases gradually from the characterization of a few tend to a straight line model characterization of the model.2. Individual estimates of the number of lines-year strategy has obvious difference. Estimated that a strong sense of individual strategies accordingly the correct strategy for estimating the extent of the use of high, and vice versa, with the higher grade and the corresponding increase.3. Three grades in the individual figures on both ends and the middle of the absolute percentage error and the variables there are different levels of the gap, with the increase in the gap year will be getting smaller and smaller, until the disappearance4. The passage of the experimental design of the game is training, second-year performance of individuals is estimated to be a very good improvement, and evaluation in relation to the expected standards in fourth grade even better individual.5. Through the design of this experiment is estimated that the strategy training, training individuals in the fourth grade is estimated to be a very good performance improvement, and evaluation criteria in the estimated reach the sixth grade, the basic estimate of the level of the individual.6. In the vertical line estimates the number of tasks, by the absolute percentage error of the individual to do multi-factor analysis of variance revealed that the main effect of year is extremely significant, the main effect of dimension is extremely significant, grade and dimensions of the interaction was not significant. In the year, the sixth grade than in fourth grade; in the horizontal dimension of the estimated performance of a good estimate of performance in the vertical.R2lin coefficient of determination and slope b with higher grade and increased gradually linear, horizontal linear dimensions are better than the linear vertical dimension; contrary R2log coefficient of determination and intercept c increased with the grade and reduce the curve gradually weakened and tend to a linear function of the horizontal linear dimensions are better than the linear vertical dimension.
