Recently, multiple studies have focused on the phenomenon of “undermatching”—when students attend a college for which they are overqualified, as measured by test scores and grades. The extant literature suggests that students who undermatch fail to maximize their potential. However, gaps remain in our knowledge about how student preferences—such as a desire to attend college close to home—influence differential rates of undermatching. Moreover, previous research has not directly tested whether and to what extent students who undermatch experience more negative post-college outcomes than otherwise similar students who attend “match” colleges. Using ELS:2002, we find that student preferences for low-cost, nearby colleges, particularly among low-income students, are associated with higher rates of undermatching even among students who are qualified to attend a “very selective” institution. However, this relationship is weakened when students live within 50 miles of a match college, demonstrating that proximity matters. Our results show that attending a selective postsecondary institution does influence post-college employment and earnings, with less positive results for students who undermatch as compared with peers who do not. Our findings demonstrate the importance of non-academic factors in shaping college decisions and post-college outcomes, particularly for low-income students. 相似文献

This study investigates early childhood prospective teachers’ attention to geometrical tasks while designing and using them in the classroom. This is explored in the context of the teaching practice of 11 prospective teachers who taught geometry in early childhood classrooms during the last semester of their university studies. The teaching practice was organized into four stages: design of a lesson plan; classroom implementation; discussion of the lesson with the school practice instructor; and self-assessment report and revision of the lesson. Analysis of data using the Teaching Triad framework (Jaworski, 1994) shows that although the prospective teachers attended to issues of mathematical challenge, sensitivity to students, and management of learning in their planning, in their actual teaching and after class reflection, their attention was focused mainly on management issues. The findings also show that prospective teachers’ attention on geometrical tasks can be developed through a process of reflection on their teaching. 相似文献

The aim of this paper is to propose a theoretical model to analyze prospective teachers?? reasoning and knowledge of real numbers, and to provide an empirical verification of it. The model is based on Sierpinska??s theory of theoretical thinking. Data were collected from 59 prospective teachers through a written test and interviews. The data indicated that mathematical tasks on real numbers, based on Sierpinska??s theory, could be categorized according to whether they require reflective, systemic or analytic thinking. Analysis of the data identified three different groups of prospective teachers reflecting different types of theoretical thinking about real numbers. The interviews confirmed the empirical data from the written test, and provided a better insight into the thinking and characteristic features of the prospective teachers in each group. The analysis also indicated that the participants were more successful in tasks requiring systemic and analytic thinking, and only when this was achieved were they able to solve problems which required reflective thinking. Implications for teaching related to the findings of the study are discussed. 相似文献

This synthesis paper explores current leadership training in science, technology, engineering and mathematics (STEM) education in Bulgaria. The analysis begins with discussion of global factors influencing the implementation of leadership training in STEM education in general and then presents information about the current status of leadership training in Bulgaria with emphases on the country's economics, politics and geographical location as specific factors influencing leadership education. A short background of Bulgaria is presented with regard to population, gross domestic product, educational system, engineering force and possible need for leaders in industry in Bulgaria and the European Union. The paper provides an overall view about the current status of leadership training in all Bulgarian universities offering STEM education and concentrates specifically on two major universities by examining their currently offered programmes. As part of the discussion, similar training elements in other European countries and the USA are presented. 相似文献

The recent development of powerful new technologies such as dynamic geometry software (DGS) with drag capability has made possible the continuous variation of geometric configurations and allows one to quickly and easily investigate whether particular conjectures are true or not. Because of the inductive nature of the DGS, the experimental-theoretical gap that exists in the acquisition and justification of geometrical knowledge becomes an important pedagogical concern. In this article we discuss the implications of the development of this new software for the teaching of proof and making proof meaningful to students. We describe how three prospective primary school teachers explored problems in geometry and how their constructions and conjectures led them see proofs in DGS.

This paper reports the outcomes of an empirical study undertaken to investigate the effect of students’ cognitive styles on
achievement in measurement tasks in a dynamic geometry learning environment, and to explore the ability of dynamic geometry
learning in accommodating different cognitive styles and enhancing students’ learning. A total of 49 6th grade students were
tested using the VICS and the extended CSA-WA tests (Peterson, Verbal imagery cognitive styles and extended cognitive style analysis-wholistic analytic test—Administration guide. New Zealand: Peterson, 2005) for cognitive styles. The same students were also administered a pre-test and a post-test involving 20 measurement tasks.
All students were taught a unit in measurement (area of triangles and parallelograms) with the use of dynamic geometry, after
a pre-test. As expected, the dynamic geometry software seems to accommodate different cognitive styles and enhances students’
learning. However, contrary to expectations, verbalisers and wholist/verbalisers gained more in their measurement achievement
in the environment of dynamic geometry than students who had a tendency towards other cognitive styles. The results are discussed
in terms of the nature of the measurement tasks administered to the students. 相似文献

This paper investigates the relations of students’ spatial and object visualisation with their analytic, creative and practical abilities in three-dimensional geometry. Fifty-three 11-year-olds were tested using a Greek modified version of the Object–Spatial Imagery Questionnaire (OSIQ) (Blajenkova, Kozhevnikov, & Motes, 2006) and two mathematics tests, one on three-dimensional arrays of cubes and one on nets. The results suggest that spatial visualisation was related to students’ practical abilities in three-dimensional arrays of cubes, whereas object visualisation was related to students’ creative abilities in nets. Furthermore, high and low spatial visualisers differed in their practical abilities in three-dimensional arrays of cubes and in their analytic abilities in nets, whereas, high and low object visualisers differed in their creative abilities in nets. 相似文献

Politics of education researchers have long recognized the role of micropolitics in school decision-making processes. We argue that investigating micropolitical dynamics is key to an important set of school decisions that are fundamental to inequities in access to high-quality teachers: assignments of teachers and students to classrooms. Focusing on the intraorganizational political power of experienced teachers, our analysis of survey and administrative data from a large urban district suggests that more experienced teachers have more influence over which students are assigned to their classrooms. By a variety of measures, we also find that more experienced teachers are assigned fewer disadvantaged students, on average, a pattern inconsistent with goals of ameliorating educational inequality by matching more qualified teachers with the students who need them most. 相似文献

This article examines whether the 7 abilities found in a previous study carried out by the authors to constitute fraction understanding of sixth grade elementary school students determine hierarchical levels of fraction understanding. The 7 abilities were as follows: (a) fraction recognition, (b) definitions and mathematical explanations for fractions, (c) argumentations and justifications about fractions, (d) relative magnitude of fractions, (e) representations of fractions, (f) connections of fractions with decimals, percentages, and division, and (g) reflection during the solution of fraction problems. The sample comprised of 182 sixth grade students that were clustered into 3 categories by means of latent class analysis: those of low fraction understanding, those of medium fraction understanding, and those of high fraction understanding. It was found that low fraction understanding students were sufficient in fraction recognition and relative magnitude of fractions, those belonging to the medium category in fraction recognition, relative magnitude of fractions, as well as in connections with decimals, percentages and division and representations of fractions, while high fraction understanding students were sufficient in all 7 abilities. It was also found that these levels were stable across time; the hierarchical levels were the same across three measurements that took place. Possible implications for fraction understanding are discussed, and directions for future research are drawn. 相似文献
