Researchers have warned of the need to identify accurately students who are underachieving in Hong Kong, particularly among the gifted group. When comparing the relative effectiveness of three methods for estimating the proportion of underachievement, the absolute split method, using an arbitrary upper and lower limits for estimates of both performance and ability, is more useful for identifying gifted underachievers than the simple difference method (where standardized performance scores are subtracted from standardized ability scores) or the regression method. In contrast, the latter two methods are more useful for identifying underachievers at all levels of ability. All three methods, however, depend on measurements that are invariant, unidimensional and additive. With the advent of modern measurement theory using Rasch measurement models, it is now possible to satisfy these requirements. In this study, a sample of Primary 5 students in Hong Kong (n = 957) were asked to complete a test of mathematical achievement and the Ravens Progressive Matrices test in order to estimate the proportion of students who are underachieving at all levels of ability. Measurement scales were created using Rasch models for partial credit and dichotomous responses for each variable, respectively, and students placed on each scale according to their responses. Because the results are based on measurement scales that are invariant between persons, the identification of underachievement in these students across all levels of ability can be regarded as objective rather than sample dependent. 相似文献

This study explores the various factors that promote positive interactions across race for African American, Asian American,
Latino, and White college students. A longitudinal survey was administered to all incoming students at nine public institutions
(with a follow-up survey given at the end of their second year), examining activities related to cross-racial interaction
and outcomes. This knowledge will be useful for college administrators, institutional researchers, and faculty as they work
to meet the challenge of preparing students for a pluralistic society. The results of this study begin to delineate the conditions
under which positive intergroup relations can be fostered in college and the key factors that inhibit or restrain the benefits
such interactions bring to the development of students for a diverse workplace and pluralistic democracy. 相似文献

ABSTRACTThe social, economic, and environmental determinants of health include employment, housing, and education; exposure to environmental factors like lead or access to healthy food; and poverty, racism and oppression. Many of these conditions can lead to Adverse Childhood Experiences that may put children and youth at risk for abuse or maltreatment leading to involvement in the child welfare or juvenile justice systems. All young people experience important developmental milestones on their path to becoming healthy adults, and while this time of change is full of promise, it can be a time of increased vulnerability or risk. For system-involved youth, navigating this time of change can be fraught with even more challenges or barriers. Without strong family and social networks, they may face increased risk of engaging in high-risk behaviors—such as unprotected sex and sex with multiple partners—as well as unintended pregnancy, HIV, and other sexually transmitted infections. Our study examined survey data to assess the overall sexual reproductive health behaviors for youth aged 14–21 in out-of-home care in an urban environment (n = 270; 60.7% male; 82% African American; 7.9% Latinx). Youth were recruited between 2012 and 2016; 76.4% of these teens had had sexual intercourse at some point in their lifetime. Of these, 86.0% were sexually active before the age of 16. Although there were numerous risk factors related to contraception and condom use as well as partner demographics, there were assets or strengths identified. A discussion of how these findings can be utilized to develop effective prevention intervention strategies is provided. 相似文献

The outcomes on multiple-choice tests and performance-based assessments for field-independent and field-dependent students were examined. A substantial interaction between cognitive style and assessment approach was found. Results suggested that performance-based assessment tended to favor field-independent subjects. Dependent on the purpose and intended use of assessment, this finding may raise concerns for validity based on either fairness or curriculum relevance. 相似文献
