The Effect Of Language On Performance: Do Gendered Languages Fail Women In Maths?

(1) Background: going to school is an important part of a child’s daily activities. A good walking distance can encourage children to walk to school. Existing methods of assessing walking distances are not specific to school-going children. (2) Methods: This study provides a method to evaluate the convenience of children going to school. Correlative indices that reflect children’s travel behavior to school and their needs in the street environment were determined based on the assessment tools of the walking environment. Factor analysis was then used to calculate the relative weight of each index. (3) Results: A new survey method was tested in the neighborhoods surrounding the Middle School of Hedong District, Tianjin, China. Walking comfort for children’s school trip was evaluated with eight indices: effective street width; street plane; street cleanliness; variety of interfaces; buffer; to cast a shadow; raw ratio; and decibels of sound. Different groups and different types of streets were found to have different vulnerabilities. (4) Conclusion: This analysis method can accurately find the weak points in the streets to improve the perception of local policy makers about the street environment, which can greatly help the implementation of appropriate measures to promote walking children to school.

Since the United Nations introduced the Child Friendly Cities (C.F.C.) initiative in 1996, 870 cities and towns around the world have received the C.F.C. certification, and more than 3,000 communities have implemented sound design and construction practices. More attention was paid to organizing and planning children’s trips, and school trips for children were an important part. Previous studies have shown that walking to and from school has a positive effect on the physical and mental health of children [1, 2, 3]. Since the streets leading to school are the primary traffic function of a child’s journey to school on foot, they play an important role in children’s daily activities. A suitable walking environment for children’s school trip not only encourages their creativity, imagination and learning ability, but also shapes their spatial knowledge and promotes social relations [4]. However, in many middle- and high-income countries around the world, rapid urbanization and automobiles have reduced the quality of the walking environment for children, leading to a significant decline in proportion of children going to school [5, 6]. Understanding how to make street environments more child-friendly has become an urgent issue to address.

Data from several previous studies have shown that major urban morphological features such as land use mix, housing density, intersections and road networks are important factors influencing school travel. active children [7, 8, 9]. ]. Some development strategies have been developed, which are difficult for urban planners and managers working in local communities to implement. One of the factors that can hinder the implementation of large-scale development strategies are real obstacles such as the lack of land resources and the high cost of demolition and construction in urban areas with a high index. of the population. In the context of promoting proper urban management, more attention should be paid to strategies and methods to improve walking spaces for school trips for children from low-income backgrounds.

Small design factors are important for determining the quality of walking spaces [10] and are highly related to people’s satisfaction with walking [11]. Therefore, we should focus more on the comfort of walking at the micro level, which means looking for environmental characteristics that affect the child’s perception of the physical and mental environment. Several studies have shown that walkability indices, including the length and width of sidewalks [12], street structure [13], shade level of street trees [14], landscape features [15], equipment social [16], and noise [17], ] affect the walking experience of pedestrians. Environmental assessment tools such as MAPS [18], PEDS [19] and SPACES [20] are common measures to measure small environmental factors and are widely used in international studies. These devices evaluate walking and cycling characteristics with expert testers who measure the exact parameters on the street. There may be differences between the test values ​​determined by the test tools due to the differences in the characteristics of the pedestrians (young, old, male, female, able-bodied/ the unfit), purpose of travel (recreational), urban environment, social environment, and cultural aspects [21. However, most of these tools ignore the importance of the relative weight of motivational factors. Knuiman et al. examined the relative importance of factors influencing mobility. Their longitudinal study in Perth, Australia showed that aspects of walking are not always equally important for walking behavior [22]. Related indices were measured mainly by questionnaires [23] and expert data [24] in related studies, where the importance of groups of indices was tested according to the preferences of the respondents and professional knowledge. However, both methods have independent claims, and we find a significant difference between the opinions of experts and citizens regarding the weight of the points to evaluate the ability to walk [25]. There are also some experts who use objective methods such as entropy process and factor analysis to directly use the collected data to calculate and present the index weight value with a solid mathematical theory. These different trends show that weight index research is important.

According to the above findings, recent studies are focusing more on the impact of the built environment on children’s walking to school. However, the main shortcoming of these studies is that few have assessed the impact of environmental factors on children’s journeys to school at a small scale to guide street planning in detail. Another major shortcoming is that the related literature does not take into account the psychological well-being needs of children during the school trip, which requires measuring the child’s emotions. The purpose of this study is to propose a method to evaluate the comfort of walking for school trips of children at the street level. The child’s independent perception and spatial needs for the street environment during the school trip were transformed from qualitative statements to measurable indices. Environmental data was collected through quantitative and qualitative analysis to assess the ease of walking in the street environment. A street network within a 10-minute walk from the Central Primary School of Hedong District, Tianjin was selected as a study site to collect children’s perceptions of street environmental conditions and behavioral characteristics. , features that helped to select and increase the indices related to the walking environment. diagnostic tools. We also discussed the effects of walking comfort and analyzed the differences and problems of different categories and types of streets to provide scientific guidance for planning, design, implementation and management. the streets.

A summary of the process of the walking comfort assessment method developed for children’s active school trips is shown in Figure 1, where the following five steps were taken. First, a representative study area was selected and the geographic area and scale were defined. Second, the index system was constructed by extracting small impact factors from widely used international environmental assessment tools, after which the indices were carefully evaluated, of modified and supplemented according to the children’s behavior and the needs of the place. Third, index data was collected through online analysis, and statistical and non-linear calculations were performed to ensure the validity of the data analysis. Fourth, we divided the indices and calculated their relative weights using factor analysis to determine the importance of different indices. Finally, the walking comfort score was calculated by analyzing the detailed indices.
