This paper analyzes the socioeconomic stratification of achievement in the Chilean voucher system using a census of 4th and 8th graders, a multilevel methodology, and accounting for unobserved selectivity into school sector. Findings indicate that the association between the school's aggregate family socioeconomic status (SES) and test scores is much greater in the private-voucher sector than in the public one, resulting in marked socioeconomic stratification of test scores in the Chilean voucher system. We also find that the amount of tuition fees paid by parents in private-voucher schools has no bearing on test scores, after controlling for the socioeconomic makeup of the school. Implications of these findings for educational inequality in the context of a universal voucher system are discussed. 相似文献

This paper argues that examinations have a complex role in creating and defining gender differences in performance in public examinations. To illustrate this argument three aspects of examining are reviewed: styles of examinations and how they define achievement; coursework and the role it plays in contributing to gender differences in performance; and tiered entry systems in examinations and how they provide unequal opportunities for boys and girls to be successful. It presents the context in which research into gender, achievement and examining is now located by initially reviewing the recent media hype around gender and achievement. It then takes an historical look at gender and achievement and goes on to describe new gender stereotypes that influence current understandings of boys' and girls' achievement. There is much information that is ‘hidden’ behind examination results as they are commonly reported. This hidden information has more to do with how differences in performance are obtained, how subjects are assessed and how we choose to assess students. How all this interacts with students' perceptions and expectations alongside those of their teachers must impact on how boys and girls perform in examinations. This ‘hidden’ information has vital implications for whom we perceive to be under or overachieving. 相似文献

Engineering design thinking is hard to teach and still harder to learn by novices primarily due to the undetermined nature of engineering problems that often results in multiple solutions. In this paper, we investigate the effect of teaching engineering design thinking to freshmen students by using a computer-aided Design (CAD) simulation software. We present a framework for characterizing different levels of engineering design thinking displayed by students who interacted with the CAD simulation software in the context of a collaborative assignment. This framework describes the presence of four levels of engineering design thinking—beginning designer, adept beginning designer, informed designer, adept informed designer. We present the characteristics associated with each of these four levels as they pertain to four engineering design strategies that students pursued in this study—understanding the design challenge, building knowledge, weighing options and making tradeoffs, and reflecting on the process. Students demonstrated significant improvements in two strategies—understanding the design challenge and building knowledge. We discuss the affordances of the CAD simulation tool along with the learning environment that potentially helped students move towards Adept informed designers while pursuing these design strategies. 相似文献

Cyberbullying research has typically been focused on specific areas, such as victimization, offender characteristics and typologies, and psychological effects for victims; however, perceived severity of cyberbullying has been studied less extensively. Using data on college students, the present study expands the current knowledge on perceived severity of cyberbullying by examining the way in which age, gender, race, type of high school attended before college, prior online victimization, and previous cyberbullying engagement influenced college students’ perceived severity of cyberbullying. Overall, the results indicate that college students considered cyberbullying to be a serious societal problem. Older individuals, females, those who attended public schools, and individuals who experienced cyberbullying victimization were found to be more likely to view cyberbullying as a serious problem than their counterparts. In addition, findings from this study revealed that even though college students perceive cyberbullying as a serious problem, the majority of those who have witnessed cyberbullying incidents would not report it to the police. Based on the findings, policy implications and practices to prevent future cyberbullying victimization are discussed. 相似文献

This paper estimates the acute effect of community-level homicides on early childhood language development and explores the moderating role of maternal efficacy and satisfaction in Chile. It uses data from the 2017 wave of the Early Childhood Longitudinal Survey of Chilean Children (N = 1194, Mage: 52.8 months, 52% girls). Children in municipalities with homicides 1 month before the Peabody Picture Vocabulary assessment scored between 0.18 and 0.41 SDs lower compared to children in the same municipality but for whom homicides happened after the assessment. On average, higher maternal satisfaction appears to have a protective effect, though it dissipates in the most violent municipalities. Evidence that higher maternal efficacy protects children from the negative effects of violence is inconclusive. 相似文献

This paper tackles the problem of a two-player differential game affected by matched uncertainties with only the output measurement available for each player. We suggest a state estimation based on the so-called algebraic hierarchical observer for each player in order to design the Nash equilibrium strategies based on such estimation. At the same time, the use of an output integral sliding mode term (also based on the estimation processes) for the Nash strategies robustification for both players ensures the compensation of the matched uncertainties. A simulation example shows the feasibility of this approach in a magnetic levitator problem. 相似文献

The Routine Activities Theory suggests that when there is the presence of a motivated offender, a suitable target, and the absence of a capable guardian, crime has the opportunity to occur. Large sporting events accompanied by massive tourists bring these ingredients of crime together. The purpose of this study is to find out whether the crime rates spike in the host cities during the high tourist month of the Super Bowl. Twenty-four months of crime rates on eight types of crimes were obtained for every American city that has hosted the Super Bowl. Panel Data Analysis is used to test the Hypotheses of this study. The findings do not show a spike in crime rates during the month of Super Bowl for any of the crimes examined in this study. It is in the economic interests of all stakeholders to provide a safe and secure venue free of crimes for sports tourists. 相似文献

Debate continues on the effects of the global proliferation of private higher-educational institutions, especially for-profit institutions. We examine two related questions for Peru using mixed methods: Who attends private institutions and what are their perceived advantages/disadvantages? Longitudinal quantitative data suggest higher-educational segmentation starting early in life, whereby young people from wealthier households attended private institutions and those from poorer households attended public ones. Interviews with teachers, students, and staff provide insights on perceived strengths and drawbacks of higher-educational marketization and highlight the importance of family background in higher-educational choices, governmental regulation, and close monitoring of higher-educational quality. 相似文献
