ABSTRACT
Background and Context
Computing is being integrated into a range of STEM disciplines. Still, computing remains inaccessible to many minoritized groups, especially girls and certain people of color. In this mixed methods study, we investigated racial and gendered patterns of equity and inequity in high school physics classrooms incorporating computational modeling, with an emphasis on group work. 相似文献13.

Background:Gross motor skills are postulated to have a bidirectional relationship with physical activity(PA);however,no study has tested this relationship before and after a summer break.The purpose of this study was to examine the bidirectional relationships between school PA and gross motor skills in children before and after a summer break.Methods:Participants were a sample of 440 children recruited from 3 low-income schools(age=8.9±1.2 years,mean±SD).PA was assessed as average school-day step counts using Yamax DigiWalker pedometers(Yamasa Tokei Keiki,Tokyo,Japan)worn for 5 consecutive school days.Gross motor skills were assessed using the Test for Gross Motor Development,3 rd edition.Data were collected at 2 timepoints:at the end of spring semester(T1)and at the beginning of the subsequent fall semester(T2).An age-and body mass index-adjusted cross-lagged model was employed to relate T1 school step counts with T2 gross motor skills and T1 gross motor skills with T2 school step counts.Results:T1 gross motor skills significantly predicted T2 school step counts(β=0.24,95%confidence interval(95%CI):0.08-0.40,p=0.003);however,Tl school step counts did not predict T2 gross motor skills(β=0.04,95%CI:-0.06 to 0.14,p=0.445).The model explained 35.4%and 15.9%of the variances of T2 gross motor skills and T2 school step counts,respectively.Additional analyses indicated that these relationships were driven primarily by ball skills.Conclusion:The relationship between gross motor skills and school PA was not bidirectional;however,higher gross motor skills,specifically ball skills,predicted higher school PA after a 3-month summer break. 相似文献

Does policy matter in shadow education spending? Revisiting the effects of the high school equalization policy in South Korea 总被引：1，自引：0，他引：1

In 1972, the South Korean government proposed the high school equalization policy (HSEP) to eliminate high-stakes exams and
introduce random school assignment to high school entrance. This policy was intended to reduce a financial burden imposed
on families due to the costs of children’s shadow education. Since its first implementation in major cities in 1974, the HSEP
has been increasingly expanded to many regions across South Korea. Yet little known is about whether the HSEP has achieved
its policy goal in terms of decreasing the demand for shadow education. Using data from a longitudinal survey of a nationally
representative sample of South Korean seventh graders, this study assesses the extent to which the HSEP makes a difference
in changes in household expenditures on shadow education during the middle school (grades 7–9). Propensity score matching
methods are used to remove selection bias and test the heterogeneity of the effects of the HSEP. Results show small effects
for the HSEP in reducing the financial burden of shadow education spending on families, particularly for lower income families.
The findings suggest that the government intervention by reducing disparities among schools and competition for entering a
particular school makes a difference in shadow education spending. 相似文献

This study examined the school perceptions and educational aspirations of 6,599 rural high school students, a sample that included 428 students with learning disabilities (LD). Regardless of disability status, rural high school students who had negative perceptions of school had less well‐defined postsecondary educational plans and less often aspired to complete college or pursue an advanced degree. Compared to nondisabled youth, rural students with LD were more likely to have negative perceptions of school and lower postsecondary aspirations. However, students with LD who had positive perceptions of school more often planned to pursue postsecondary education and aspired to complete college or an advanced degree. Implications for research and interventions pertaining to the educational attainment of students with LD are discussed. 相似文献

Class examples for a standard introductory statistics course usually involve a variety of applications. In this paper, we consider the teaching of statistics using forensic science and the law, an area that holds some fascination with many audiences. 相似文献

Over the past few decades, South Korea has made remarkable achievements in education despite many obstacles. Education, in turn, has played an important role in Korea??s achieving both economic development and political democracy. This article examines how South Korea expanded access to education and improved its quality. The article also identifies several tasks Korean education faces in the context of the new challenges of globalization and social polarization, and some of the broader policy implications that the Korean model of educational development has beyond South Korea. 相似文献

Bringing successful teaching approaches for stimulating conceptual change to normal classrooms has been a major challenge not only for teachers but also for researchers. In this study, we focused on the relationship between cognitive conflict and responses to anomalous data when students are confronted with a counterintuitive demonstration in the form of a discrepant event. The participants in this study were 96 secondary school students (9th grade) from S. Korea. We investigated students?? preconceptions of motion by administering a written test. After the exam, we presented a demonstration that may have conflicted with the ideas held by students. We then investigated the relationship between students?? cognitive conflict and responses to anomalous data by using a Cognitive Conflict Level Test (CCLT). Results showed that cognitive conflict initiated the first step in the process of conceptual change. Anxiety was an especially crucial component of cognitive conflict, affecting the relationship between cognitive conflict and students?? responses. In addition, superficial conceptual change was found to be the most common response. 相似文献

We utilised four waves of TIMSS data in addition to the information we have collected on countries’ educational systems to examine whether different degrees of standardisation, differentiation, proportion of students in private schools and governmental spending on education influence students’ math achievement, its variation and socioeconomic status (SES) gaps in math achievement. A higher level of standardisation of educational systems was associated with higher average math achievement. Greater expenditure on education (as a percentage of total government expenditure) was associated with a lower level of dispersion of math achievement and smaller SES gaps in math achievement. Wealthier countries exhibited higher average math achievement and a narrower variation. Higher income inequality (measured by the Gini index) was associated with a lower average math achievement and larger SES gaps. Further, we found that a higher level of standardisation alleviates the negative effects of differentiation in the systems with more rigid tracking. 相似文献
