Nearly 60 percent of college students today are women. Using longitudinal data on a nationally representative cohort of eighth grade students in 1988, I examine two potential explanations for the differential attendance rates of men and women—returns to schooling and non-cognitive skills. The attendance gap is roughly five percentage points for all high school graduates. Conditional on attendance, however, there are few differences in type of college, enrollment status or selectivity of institution. The majority of the attendance gap can be explained by differences in the characteristics of men and women, despite some gender differences in the determinants of college attendance. I find that higher non-cognitive skills and college premiums among women account for nearly 90 percent of the gender gap in higher education. Interestingly, non-cognitive factors continue to influence college enrollment after controlling for high school achievement.  相似文献

This study describes a new teaching model for ultrasound (US) training, and evaluates its effect on medical student attitudes toward US. First year medical students participated in hands‐on US during human gross anatomy (2014 N = 183; 2015 N = 182). The sessions were facilitated by clinicians alone in 2014, and by anatomy teaching assistant (TA)‐clinician pairs in 2015. Both cohorts completed course evaluations which included five US‐related items on a four‐point scale; cohort responses were compared using Mann‐Whitney U tests with significance threshold set at 0.05. The 2015 survey also evaluated the TAs (three items, five‐point scale). With the adoption of the TA‐clinician teaching model, student ratings increased significantly for four out of five US‐items: “US advanced my ability to learn anatomy” increased from 2.91 ± 0.77 to 3.35 ± 0.68 (P < 0.0001), “Incorporating US increased my interest in anatomy” from 3.05 ± 0.84 to 3.50 ± 0.71 (P < 0.0001), “US is relevant to my current educational needs” from 3.36 ± 0.63 to 3.54 ± 0.53 (P = 0.015), and “US training should start in Phase I” from 3.36 ± 0.71 to 3.56 ± 0.59 (P = 0.010). Moreover, more than 84% of students reported that TAs enhanced their understanding of anatomy (mean 4.18 ± 0.86), were a valuable part of US training (mean 4.23 ± 0.89), and deemed the TAs proficient in US (mean 4.24 ± 0.86). By using an anatomy TA‐clinician teaching team, this study demonstrated significant improvements in student perceptions of the impact of US on anatomy education and the relevancy of US training to the early stages of medical education.

Undoubtedly the acquisition of mathematical skills for problem solving is critically important in today’s sophisticated technological world. There is growing evidence that meta-cognition application is an important component of academic success in general and impacts on mathematical achievement in particular. Teachers’ application of meta-cognition therefore directs and reflects their teaching-practice behaviour which influences their learners’ learning with understanding in problem-solving. The purpose of the study reported on in this article was to explore teachers’ available meta-cognitive skills in class with the intention of supporting learners’ development of mathematics in problem-solving in some selected rural primary schools in the Eastern Cape, South Africa. The participants were three teachers purposefully selected from three primary schools. Interviews were conducted with the three teachers and three lessons were observed. The interviews, as an extension of observation, focused on the teachers’ knowledge or understanding of available meta-cognitive skills and how they used these skills in helping their learners’ development of mathematics problem-solving. The findings included a detailed exploration of the teachers’ acquisition and use of specific metacognitive skills, either consciously or unconsciously, during teaching and learning processes in order to develop their mathematics learners’ meta-cognitive skills as well as in solving mathematical problems. The results of the observation showed that there was evidence of teachers applying meta-cognitive skills unconsciously in assisting their learners in problemsolving in class. The interviews confirmed this evidence of available meta-cognitive skills which the teachers usually applied in assisting their learners in problem-solving in class. Recommendations have been made regarding teachers’ methods of teaching to improve the development of such skills in the lives of their mathematics learners through problemsolving.  相似文献

Through analysis of five focus groups with people who “usually (more often than not) listened to at least one podcast episode a week” in the last two months, this uses and gratifications (U&G) study uncovers several prominent themes among podcast listener experiences. In an effort to integrate old and new media use typologies within U&G research, our results are presented in two parts: emerging typologies and expansions of existing typologies. The emerging section includes reasons for podcast displacement of other media, customizable experiences, and multitasking (which involves both temptation bundling and feeding the brain). The expansion builds on the existing typologies of companionship and interaction by analyzing avenues for parasocial relationship formation and identifying social opportunities as well as social frustrations surrounding podcasts. We ultimately conclude that podcasts offer an endless supply of engaging content that travels with listeners, allowing them to be “productive” in various physical and mind-expanding ways. The enjoyment is facilitated in part by forging connections with hosts and other listeners.  相似文献

The purpose of this study was to better understand teacher tensions in professional development. The population under study was practicing mathematics teachers engaged in a week-long professional development institute. Data sources included observations, interviews, and teacher products (such as registration forms, surveys, journals, and notebooks). The data were analyzed to determine what tensions were evident in the institute and how those tensions arose. In this paper, we examine participants’ tensions in a professional development situation when their expectations did not match reality. We have done so by presenting a theoretical model of professional development based on an instructional rhombus that illuminates the actual and applicatory aspects of teachers’ professional development experiences. The main tensions expressed by the teachers were related to the content and pedagogy of the institute. This study points toward the importance of teachers’ expectations in professional development.  相似文献

Since the beginning of the 1990s, Sweden has been transforming its national research policy into policy for innovation. One of the bottom up responses to this top d initiative has been an attempt on the part of some Swedish universities to transform themselves into entrepreneurial institutions. This paper uses a case study of one particular Swedish University; Chalmers University of Technology’s transformation process to reflect on the new research policy. Chalmers’ journey is examined against the backdrop of the changing national climate for universities as well as local factors within the university itself.The case confirms existing knowledge in that it shows that creating an entrepreneurial university takes several years as both infrastructural and cultural changes are necessary to achieve success. The case also shows that despite the long history of public-private in Sweden, the new emphasis on commercialisation and commodification of knowledge creates some degree of role uncertainty for universities. The paper concludes that one of the elements required for Swedish innovation policy is macro (policy vision and implementation) and micro (university organisation) level flexibility and diversity.  相似文献

To better understand ethical issues involved in the field of human genetics and promote debate within the scientific community, the author surveyed scientists who engage in human genetics research about the pros, cons, and ethical implications of genetic testing. This study contributes systematic data on attitudes of scientific experts. The survey finds respondents are highly supportive of voluntary testing and the right to know one's genetic heritage. The majority consider in utero testing and consequent pregnancy termination acceptable for cases involving likelihood of serious disease but disapprove for genetic reasons they consider arbitrary, leaving a gray area of distinguishing between treatment of disorders and enhancement still to be resolved. While safeguarding patient confidentiality versus protecting at-risk third parties (kin, reproductive partners) presents a dilemma, preserving privacy from misuse by institutional third parties (employers, insurers) garners strong consensus for legislation against discrimination. Finally, a call is made for greater genetic literacy.  相似文献

Awareness has been extensively studied in human computer interaction (HCI) and computer supported cooperative work (CSCW). The success of many collaborative systems hinges on effectively supporting awareness of different collaborators, their actions, and the process of creating shared work products. As digital libraries are increasingly becoming more than just repositories for information search and retrieval – essentially fostering collaboration among its community of users – awareness remains an unexplored research area in this domain. We are investigating awareness mechanisms in CiteSeer, a scholarly digital library for the computer and information science domain. CiteSeer users can be notified of new publication events (e.g., publication of a paper that cites one of their papers) using feeds as notification systems. We present three cumulative user studies – requirements elicitation, prototype evaluation, and naturalistic study – in the context of supporting CiteSeer feeds. Our results indicate that users prefer feeds that place target items in query-relevant contexts, and that preferred context varies with type of publication event. We found that users integrated feeds as part of their broader, everyday activities and used them as planning tools to collaborate with others.  相似文献
