We present a science centre established in Genoa on an agreement between Municipality of Genoa and Department of Physics of University of Genoa. The aim is to offer children, young people and community an opportunity to approach science in a playful way. The centre staffs guide the visitors through the exhibits, attracting their interests towards the most amusing aspects of the phenomena. According to the principles of constructivism, kids and children are encouraged to handle objects, play with geometrical shapes, observe materials collected from natural and human environment and make "discoveries", and students can take advantage of the visit and from the exhibits to study in depth a specific topic afterwards in their class, thus preventing the aridity of a purely formal presentation of the discipline, while a general public can realize how much science affects people's lives, enjoy its fun aspects and meet scientists during special events. 相似文献

Much research has been conducted to document and sometimes to provide proximate explanations (e.g., Confucianism vs. Western
philosophy) for East–West cultural differences. The ultimate evolutionary mechanisms underlying these cross-cultural differences
have not been addressed. We propose in this review that East–West cultural differences (e.g., independent versus interdependent
self construal; autonomy versus harmony in values; hierarchical versus egalitarian relationships) result from social learning
and individual learning as primary means to adapt to the local environment. Historical and contemporary evidence from multiple
sources is reviewed that indicates smaller extents of environmental variability in East Asia including China than in Europe
and North America, favoring social learning in the East and individual learning in the West. Corresponding to these different
adaptive strategies, East–West differences stem from learning styles that differ between copying and rote memorization, on
the one hand, and critical thinking and innovative problem solving, on the other hand. These primary cultural differences
are correlated with such personality attributes as conformity, compliance, and independence that serve to facilitate social
or individual learning. This and other cross-cultural and educational psychological research is reviewed as evidence to support
our evolutionary explanation of why Eastern and Western cultures differ in the ways in which they do. 相似文献

The aim of the study was to evaluate our practice of self-directed learning (SDL) among pre-university students in Malaysia. Respondents provided data on their previous school learning experiences besides present SDL experiences in college. We carried out exploratory factor analysis based on the school data. We did a confirmatory factor analysis using College SDL experiences of students. Given high similarities between the measurement models, we decided to use the original structure of the instrument. Students provided feedback using a questionnaire based on Prociuk’s. A large majority declared that they needed SDL experiences which they lacked while at school. The study also showed that students had rated their SDL experiences in college more positively than in school, on four factors of SDL experiences. Pearson correlations showed that “knowledgeable and organised teachers” and “promotion of active learning” correlated significantly with students’ current satisfaction with SDL in college. 相似文献

Mathematics education and learning disabilities in Spain 总被引:1,自引:0,他引:1
In the first part of this article, we describe the basic objectives of the math curriculum in Spain as well as the basic contents, teacher resources, and obstacles perceived in mathematics instruction. Second, we briefly describe the concept of learning disabilities (LD) as they are currently defined in Spain. As stated in the recent educational reform, a student with LD is any student with special educational needs. The emphasis is placed on the educational resources that these students need in order to achieve the curricular objectives that correspond to their age group or grade. Third, we comment specifically on the educational services model and the evaluation and instructional procedures for students with math learning disabilities. Finally, we describe some lines of research that have appeared in the last few years in Spain that have led to the development of new evaluation and intervention procedures for students with LD in computation and problem solving. 相似文献

AbstractThis report aims (1) to examine the association between seasonality and physical activity (PA) and sedentary time in European adolescents and (2) to investigate whether this association was influenced by geographical location (Central-North versus South of Europe), which implies more or less extreme weather and daylight hours. Valid data on PA, sedentary time and seasonality were obtained in 2173 adolescents (1175 females; 12.5–17.5 years) included in this study. Physical activity and sedentary time were measured by accelerometers. ANCOVA was conducted to analyse the differences in PA and sedentary time across seasons. Results showed that girls had lower levels of moderate to vigorous PA (MVPA) and average PA, and spent more time in sedentary activities in winter compared with spring (all P < 0.05). Stratified analyses showed differences in PA and sedentary time between winter and spring in European girls from Central-North of Europe (P < 0.05 for sedentary time). There were no differences between PA and sedentary time across seasonality in boys. In conclusion, winter is related with less time spent in MVPA, lower average PA and higher time spent in sedentary activities in European adolescent girls, compared with spring. These differences seem to mainly occur in Central-North Europe. 相似文献

Purpose: The purpose of the present study was to investigate the effects of self-controlled feedback on the learning of a sequential-timing motor task in introverts and extroverts. Method: Fifty-six university students were selected by the Eysenck Personality Questionnaire. They practiced a motor task consisting of pressing computer keyboard keys in a specific spatial and temporal pattern. The experiment consisted of practice, retention, and transfer phases. The participants were distributed into 4 groups, formed by the combination of personality trait (extraversion/introversion) and type of feedback frequency (self-controlled/yoked). Results: The results showed superior learning for the groups that practiced in a self-controlled schedule, in relation to groups who practiced in an externally controlled schedule, F(1, 52) = 4.13, p < .05, η2 = .07, regardless of personality trait. Conclusion: We conclude that self-controlled practice enhances motor learning in introverts and extroverts. 相似文献

A highly touted feature of the so-called global “revolution” in higher education is the trend to use information technology
to reach a broader clientele. Although there is evidence that students may be learning the material in on-line courses as
well as in traditional face-to-face universities, how well students learn content is not the only reason they persist to a
degree, and student persistence is an important goal of higher education institutions. In this paper, we make the case that
the life conditions for students attending virtual universities are different from those of “traditional” students in face-to-face
universities, and that this difference puts a particular (largely non-pecuniary) premium on time to degree. With our data
from a Catalan virtual university, the Open University of Catalonia (UOC), we are able to test this hypothesis directly by
using the heterogeneous degree structure of the Catalonian/Spanish higher education system to estimate whether the number
of courses required to get various degrees (the length of the degree program) is significantly related to student persistence.
The study analyzes several cohorts of students (those who entered in 2000–2003) studying in the UOC and estimates the factors
that influence their degree completion. We find that the completion rate is generally low, but that students taking shorter
degree courses at the UOC are much more likely to complete their degrees. This suggests that, given their clientele, on-line
universities operate under very different constraints from their face-to-face counterparts. Our results are important for
higher educational researchers, who have mainly focused on younger populations attending face-face universities. They also
can serve university administrators who launch distance education degree programs and make high stakes decisions about them
with little of no information on the likely behavior of their older students, and can serve employers who are deciding whether
to subsidize their employees to take advanced degrees through on-line programs of study. 相似文献

The Technology Foundation Course for Women at Huddersfield Polytechnic is designed to help women compensate for their previous lack of experience in technology and to prepare them to enter diploma and degree courses in higher education. The course has several distinctive features in that it is for women only and is designed to meet the needs of mature students with family commitments. Students are allowed flexibility in their choice of subjects, enabling them to study mathematics, physics, computing or chemistry to approximately A‐level standard. Students from the first intake have evaluated the course positively and the majority are studying computing or engineering‐related subjects in higher education. The design of the course is discussed in the light of the requirements of women taking the course and the demand within industry and higher education for more qualified scientists and engineers. 相似文献

In this paper, we propose a numerically robust blind equalization scheme to mitigate cochannel and intersymbol interferences and separate signals from a convolutive mixture in multiple-input multiple-output (MIMO) communication systems. The robustness of the proposed scheme is achieved through a particular dual-mode operation applied to a constant-modulus-based space-time algorithm that corrects phase rotations. In the first mode of operation, the consistency in the nonlinear estimates of the transmitted signals is ensured. In the second mode, the Euclidean norms of the equalizer coefficient vectors decrease along the iterations, which allows the algorithm to return to the first mode of operation, where the estimation of the transmitted signals really occurs. In particular, we apply this scheme to a multimodulus version of the multiuser Shalvi-Weinstein algorithm (MU-SWA). By means of a deterministic stability analysis assuming the persistence of excitation condition, we show that the dual-mode MU-SWA does not diverge. 相似文献
