On November 10, 2005, then Superintendent of the Kalamazoo Public School System, Janice Brown announced—to the surprise of Kalamazoo’s residents—the beginning of the Kalamazoo Promise. Fully funded by a set of anonymous donors, the Kalamazoo Promise is an urban revitalization program that offers up to four years of free tuition to any public college or university in the state of Michigan for graduates of the Kalamazoo Public School system who meet certain eligibility criteria. Using the subsidy as a source of exogenous variation in the price of college, we use quasi-experimental methods to evaluate the impact of the subsidy on college choice. We find that the Kalamazoo Promise increases the likelihood that students from Kalamazoo Public Schools consider public institutions in Michigan. In addition, we find that the Kalamazoo Promise especially impacts the college choice set of students from families who earn less than $50,000 in annual income. 相似文献

Opportunities to Learn in the Budapest Mathematics Classroom 总被引:1,自引:0,他引:1
Paul Andrews 《International Journal of Science and Mathematics Education》2003,1(2):201-225
This paper examines the nature of the problems posed, the processes by which their solutions were made public, their structural contribution to a lesson and the opportunities they offered for the learning of mathematics in Budapest, Hungary. The problems were derived from observations, the processes of which were informed by various comparative studies, of 94 mathematics lessons in the 10–14 age range. Problems, the analysis and categorisation of which were informed by the literature, tended to fall into two categories – single response with high levels of cognitive demand and multiple response with high levels of cognitive demand. Structurally lessons fell into a well practised pattern of classroom behaviour. They began with a public review of homework, comprising two or three multiple response problems which were solved collaboratively. This was followed by a warm-up period involving the oral setting and mental solving of a few single response problems. Lastly, the main body of the lesson involved several cycles in which a multiple response problem was posed, attempted individually before solutions were shared publicly. Lessons ended with homework being set. The discussion of the findings is framed by Hungary's variable performance on recent international tests of mathematical attainment. 相似文献

This study explores biology undergraduates' misconceptions about genetic drift. We use qualitative and quantitative methods to describe students' definitions, identify common misconceptions, and examine differences before and after instruction on genetic drift. We identify and describe five overarching categories that include 16 distinct misconceptions about genetic drift. The accuracy of students' conceptions ranges considerably, from responses indicating only superficial, if any, knowledge of any aspect of evolution to responses indicating knowledge of genetic drift but confusion about the nuances of genetic drift. After instruction, a significantly greater number of responses indicate some knowledge of genetic drift (p = 0.005), but 74.6% of responses still contain at least one misconception. We conclude by presenting a framework that organizes how students' conceptions of genetic drift change with instruction. We also articulate three hypotheses regarding undergraduates' conceptions of evolution in general and genetic drift in particular. We propose that: 1) students begin with undeveloped conceptions of evolution that do not recognize different mechanisms of change; 2) students develop more complex, but still inaccurate, conceptual frameworks that reflect experience with vocabulary but still lack deep understanding; and 3) some new misconceptions about genetic drift emerge as students comprehend more about evolution. 相似文献

Research Findings: The present study examined the degree to which the association between interactive peer play and academic skills was dependent upon the level of classroom quality for a representative sample of culturally and linguistically diverse urban Head Start children (N = 304 children across 53 classrooms). Peer play interactions within the classroom were assessed by teacher assistants in the fall of the year; observations of the quality of classroom instructional, emotional, and organizational support were conducted in the middle of the year; and norm-referenced direct assessments of literacy, language, and mathematics skills were administered in the spring. Findings from multilevel models indicated that disruptive and disconnected peer play behaviors early in the preschool year were associated with lower literacy and language skills regardless of classroom quality. However, interactive peer play early in the year was associated with higher mathematics outcomes when children were enrolled in classrooms characterized by high instructional support. Practice or Policy: Implications for early childhood research, practice, and policy are discussed. 相似文献

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (Mage = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. 相似文献
