The objective of this study was to check attitudes towards mathematics and to analyse if there are differences in attitudes that could be attributed to the type of school, gender, grade, age, the frequency in which mathematical problems were understood, the amount of days dedicated to the study of mathematics, school failure, whether help on the completion of homework was offered and to the self-perception of mathematical performance. A total of 209 students of the 3rd and 4th Grades of basic education in the private school system in Campinas, Sao Paulo, Brazil, were surveyed. They responded to an attitude towards mathematics scale and to a questionnaire for their characterisation, during school hours and in the absence of their mathematics teacher. The average figure on the attitudes scale was 52.718, with a standard deviation of 11.837. Significant statistical differences were found (alpha = 0.05) in the attitudes according to the type of school, the frequency in which the subjects understood the mathematical problems solved in the classroom, grade, age and to the self-perception of mathematical performance. 相似文献

In a longitudinal study, we looked at the link between children'sunderstanding of a morphemically-based orthographic rule and theirawareness of morphemic distinctions. The orthographic rule in question wasthe use of the apostrophe to denote possession in English. Early on in thestudy, we gave the children phonological, semantic/syntactic and morpho-syntactic awareness tasks, and later we gave them a spelling task in whichthey had to write words which were either genitives (e.g., `boy's') ornominative or accusative plurals (e.g., `boys'). Eight- to 10-year-oldchildren found this task difficult, but their performance improved to someextent with age. The morpho-syntactic, but not the phonological orsemantic/syntactic, awareness tasks predicted how well the children placedapostrophes in genitive words and omitted them from plural words. Weconclude that different forms of linguistic awareness affect differentaspects of reading and spelling. Learning about spelling patterns based onmorphemes is heavily influenced by children's morpho-syntactic awarenessbut not, apparently, by other forms of linguistic awareness. 相似文献

This paper examines a range of issues concerned with the process of choosing schools in the private and state sectors at the primary/pre‐preparatory stage and at the time of transfer to secondary/senior school. The findings indicate that choices about schools are made at different times and in different ways by parents who use the state and private sectors. One of the key findings is that the process of choosing a school begins earlier in the private than in the state sector; another is that quality of education is cited more frequently as one of the ‘top three’ essential factors by parents of children in the private sector. At both the primary and transfer to secondary stages, very high percentages of parents consider it essential that their child should be happy. A discussion of the different notions that private school and the state school parents may have of ‘happiness’ is offered. 相似文献

The purpose of this study was to examine the validity of a highly popular pedometer application (Samsung Health). Sixteen adults (28.8 ± 8.9 years of age) wore two Samsung smartphone models, Samsung Galaxy Core Prime (SGCP) and Samsung Galaxy S4 (SGS4), at three body locations (waist, arm, and hand) while walking and running over a 50-m test. All trials were recorded using a video as a gold standard measure of step counts. Results indicated that the validity of Samsung Health varied depending on the smartphone model, its body location, and the type of gait (walking and running). Samsung Health showed acceptable validity when the SGCP was located on the hand (Bias = ?8.3%; RMSE = 5.6), and especially on the arm (Bias = ?7.2%; RMSE = 4.9) while running, and when the SGS4 was located on the arm (Bias = ?7.5%; RMSE = 5.4), and especially on the waist (Bias = 5.4%; RMSE = 3.7) while walking. Samsung Health only showed good validity when the SGS4 was located on the arm (Bias = 2.9%; RMSE = 3.6), and especially on the hand (Bias = 0.5%; RMSE = 2.5) while running. This application showed unacceptable validity in the remaining options. 相似文献
