The article considers, on one hand, the need to increase East‐West and West‐East academic exchanges in Europe, and on the other, to reduce or to rationalize imbalances. The three major segments of university populations, students, faculty members, and administrators, are each examined with regard to participation in exchanges, and pertinent suggestions are made. The author particularly insists on the importance of involving university administrators in exchange programmes even to the extent of moving them physically to other universities for stays of varying length. In closing, he evokes the setting up of the European Association of International Exchange Administrators.  相似文献

Abstract This article aims to capture the spirit and content of a lively exchange among museum staff members at the Denver Art Museum. It began as a conference call and continued as an online dialogue about how definitions of success have evolved with advances in technology and changing expectations of visitors. Together we explored how DAM staff encourage more active participation in the museum and the creative tension that ensues between visitor co‐creation and institutional control. Woven throughout this conversation are examples that demonstrate the need to move fluidly between high tech and low tech interpretives, onsite and online experiences, and the impact of environments that break down museum stereotypes. It is our hope that this discussion will spark similar dialogues among colleagues in individual institutions and in the profession at large.

The expansion in the number of people entering higher education has resulted in a substantial increase in the proportion of students enrolling in nontraditional modes, such as part-time study. This study examined the question of whether part-time study curtails the development of the types of intellectual capabilities needed for a knowledge-based economy, because the students would have markedly less exposure to a stimulating campus environment than their full-time counterparts. Graduates from discrete full- and part-time programs from 1 university in Hong Kong completed a survey seeking perceptions of the nurturing of a range of capabilities, together with measures of teacher-student relationships and type of teaching experienced. Two hypotheses were tested by structural equation modeling: (a) the same mechanism for capability development operated for full- and part-time modes and (b) the principal element of the mechanism was the nature of teaching and the quality of teacher-student interaction. Hypothesis 1 was supported because configural invariance between hypothesized models for capability development between the 2 modes was found. Hypothesis 2 was also supported because the models showed that the principal influence on capability development came from teaching for understanding, through promoting active learning experiences and the degree and quality of teacher-student interaction.  相似文献

It is widely accepted that postsecondary education has become a necessity for US youth. College access, however, has been found not to be equal for all. As a result, federally funded college-readiness programs, such as Gaining Early Awareness and Readiness for Undergraduate Programs (GEAR UP), have been established to increase the numbers of economically disadvantaged students with access to college. This quasiexperimental case study compared academic and nonacademic college-readiness indicators between cohorts of GEAR UP students and nonparticipants in 1 urban high school. Overall, cohorts of GEAR UP students outperformed their non-GEAR UP peers on all measures (grade-point average, attendance rate, behavior, graduation rate, and college enrollment) despite a dramatic demographic shift that led to greater proportions of educationally disadvantaged students in the GEAR UP cohorts.  相似文献

Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(<9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95%confidence interval(95%CI):1.68-3.35,p<0.0001)hazards ratio of HF as compared with men with high ECP(>13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was associated with a 1.96-fold risk(95%CI:1.38-2.78,p<0.001)of HF after additional adjustment for conventional risk factors.After further adjustment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95%CI:1.31-2.66,p<0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28%(95%CI:17%-37%).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake.  相似文献

The mechanical transmission of motion, which is observable in gears’ turning direction (TD) and turning speed (TS) can be understood as part of the core concept “force and motion”. Previous studies have suggested that most children before the age of nine have naïve concepts of gears’ TD and TS. However, these studies relied on children's explanation data and might have therefore underestimated young children's potential. Moreover, these studies did not examine whether preschoolers can overcome their naïve concepts through teaching. Recently, educators have proposed guided play as an educational approach that combines children's play with teacher guidance in a purposefully designed environment. We conducted two subsequent studies. In Study 1, we investigated the children's (naïve) concepts of gears’ TD and TS with a cross‐sectional approach using a nonverbal test procedure. This study comprised 248 children aged 5–10 years and 73 adults. The results showed that the proportion of children with adequate concepts increased with age. More specifically, 7‐ to 8‐year‐olds differed significantly from 5‐ to 6‐year‐olds, indicating a developmental shift around this age. However, naïve concepts of TS were more persistent with age than naïve concepts of TD. Altogether, the results indicated the potential to foster 5‐ to 6‐year‐olds’ concepts of both TD and TS in an intervention. Thus, in Study 2, we developed and tested a guided play intervention to foster 5‐ to 6‐year‐old children's concepts of TD and TS. We conducted a prepost‐intervention design with a guided play group (n = 19) and a free play group (n = 21). The results suggested stronger learning gains in the guided play group (dTD = 0.337, dTS = 0.758) than in the free play group (dTD = 0.224, dTS = 0.158).  相似文献

ABSTRACT— The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.  相似文献

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students’ concept maps using an itemized holistic marking guide. Their marking was compared with the researchers’ marking and the scores of a multiple-choice diagnostic test. Statistical analysis revealed that teachers evaluated students’ concept maps consistently, but the concept map scores were only mildly correlated with the multiple-choice test scores. We explored what each assessment method revealed in terms of students’ understanding with one student’s performance as a showcase. Teachers’ views on using the marking guide of concept maps as an assessment tool were also included. We discuss the value of the concept map marking guide as a formative assessment tool for science teachers to create and modify in order to encourage students’ conceptual learning.  相似文献
