In Grutter vs. Bollinger, the U.S. Supreme Court ruled that the use of race as one factor, among many in admissions decisions is constitutional. It is not known, however, whether future legal opinions will continue to uphold the use of affirmative action policies. Some have argued that class-based preferences can achieve many of the same goals as in affirmative action while being more likely to withstand legal challenges. To date, no empirical studies have been conducted on the potential impact of a class-based admissions policy if implemented at an undergraduate institution. This paper reports on a study at a selective public college and compares a number of outcomes under three admissions models: the original admissions decisions, a purely academic model, and an socio-economic status (SES)-based model. The findings showed that use of the SES-based model would have led to a more academically qualified class than in the original admitted class while maintaining substantially greater student diversity that was found under the academic model. An admissions policy based on preferences for socio-economically disadvantaged applicants appears to hold promise for other colleges and universities with similar institutional and applicant characteristics. The ideas and research design reported in this paper are based on the doctoral dissertation study of the second author, Undergraduate Admissions Models Incorporating Socioeconomic Factors (Johnson, 2000).  相似文献

Theories of adolescent connectedness suggest that adolescents strive to become connected by engaging with and valuing the people, activities, and worlds in their social ecology. The purpose of this study was to examine the psychometric properties of a measure designed to assess these worlds of connectedness among 320 junior high school students in Taiwan. The subscales and composite scales evidenced satisfactory reliability and concurrent validity. A hypothesized three-factor, higher order structural model of connectedness was cross-validated. Girls were generally more connected than boys. Both connectedness to school and to friends explained more variance in connectedness to self than did family connectedness. There was mixed support for separation-individuation processes. The measure appears promising in terms of future research on adolescent social development in the Asia Pacific.  相似文献

死神与诗人     
这首诗出自于英国 17 世纪伟大诗人约翰·邓恩 ( 1572 ̄1631) 的《神圣十四行诗》。约翰·邓恩系玄学派代表诗人, 其诗歌通常给人留下一种舞台戏剧的印象。诗的开篇大都是以语言通俗、言辞激烈的戏剧性对话或争论的形式出现, 渲染了戏剧的舞台气氛, 在读者中产生戏剧悬念, 既而推动诗歌主题步步升华。诗人独具匠心, 在诗歌中巧妙运用戏剧表现手法, 通过使用一系列注重智力, 意象华丽且富含戏剧对比性因素的比喻, 将激情与推理融为一体, 给诗歌注入了新的活力, 向读者传达了奇妙的艺术效果。  相似文献

“What is that sound?”, “What did the kangaroo say?”, and “What might you hear during a walk?” provide evidence that educators of young children realize that listening represents a necessary ingredient in successful school experiences. Children listen for many hours of the school day, but listening has been a neglected area of instruction. The traditional low priority of listening instruction may have been based upon the myth that children naturally learn to listen or on the misconception that listening skills cannot be taught. Using literature to teach listening can improve learners' listening abilities, provided early childhood educators use developmentally appropriate children's literature.  相似文献

This paper presents the third version of a technological pedagogical content knowledge (TPACK) based instructional design model that incorporates the distinctive, transformative, and integrative views of TPACK into a comprehensive actionable framework. Strategies of relating TPACK domains to real-life learning experiences, role-playing, and teachers as designers were developed based on the three views and integrated into the third version of the model. The model was then applied in a teacher education undergraduate course on technology integration. A case study approach was used. Data were collected from the participants’ discussion worksheets, lesson designs, and the researchers’ field observation notes. Data analysis results suggest that the strategies integrated into the model helped the participants deepen their understanding of student-centered technology applications and practice TPACK. Findings, implications, and future research possibilities are discussed.  相似文献

This article attempts to characterize the general problem of selecting methods for decision-making. The traditional rational approach to choice is from economics, which offers expected-value maximization. The task environment of decision method selection, however, does not seem to provide the data necessary for carrying out the expected-value calculations. Our approach uses methods from the field of cognitive science. We develop the notion of domain size in fields such as chess, borrowing the concept of a chunk from human memory. We then develop a heuristic rule for choiceamongmethods. We propose this rule as one of many possible rules.  相似文献

Examined in this study were three procedures for estimating the standard errors of school passing rates using a generalizability theory model. Also examined was how these procedures behaved for student samples that differed in size. The procedures differed in terms of their assumptions about the populations from which students were sampled, and it was found that student sample size generally had a notable effect on the size of the standard error estimates they produced. Also the three procedures produced markedly different standard error estimates when student sample size was small.  相似文献
