How evident is democracy within education in Japan, and is current practice different from elsewhere? This paper assesses the perception that Japanese political and educational practices are not fully 'democratic'. The first part examines the Japanese perspective on democracy, and then considers democracy and education in Japan. From a school-based study, the second part discusses examples of class practice concerning decision-making. The paper concludes that democracy is deeply rooted in Japanese history, but not in a form that is readily recognisable to Western observers. Consensus has been more significant than voting. The view that the US administration had a strong influence probably reflects policy rhetoric, not the reality in schools. But this rhetoric may have led to a belief that 'democracy' is not an appropriate term within contemporary Japanese education. However, what happens in Japanese classrooms equates with 'democratic' practice elsewhere.  相似文献

Lifelong learning is receiving greater attention due to population aging in modern societies. Lifelong learning benefits individuals by supporting their physical, psychological, social, and economic well-being. However, older adults generally have lower motivation for learning than younger adults, and facilitating long-term participation in learning activities is still challenging. Previous studies mainly identified negative factors such as barriers and obstacles to individuals’ initial participation in lifelong learning programs. As such, less is known about positive factors that promote long-term participation. To address this gap, data were collected from 330 older adults who participated in the Osher Lifelong Learning Institute program in an urban community in the United States. Results from proportional odds ordinal logistic regression analysis demonstrated that gender, number of household members, income, religious affiliation, self-rated health, and number of courses taken were associated with satisfaction with the program. In hopes to promote true lifelong learning, possible explanations about the findings are explored and several recommendations for existing lifelong learning programs are derived in this study.  相似文献

One of the main approaches used in communicating environmental issues to citizens is conveying ‘factual’ information about a particular environment. However, despite previous research and recommendations made by critical environmental educators, there still seems to be a belief that the more ‘factual’ information one can convey, the more citizens will become aware of the issue, and this will prompt them to change their behaviours. In this article, I will argue that continuing with a ‘fact’-focused practice in Japan and elsewhere could be problematic for three key reasons: (1) it ignores diversity in the ‘facts’ provided to people; (2) it reinforces the ‘hierarchy of knowledge’; and (3) it ignores the ‘myth of nature’ among information receivers and senders. Key recommendations for incorporating a critical environmental education approach include utilising locally available environmental information on contentious environmental issues; investigating particular terminology used and missing information (including tacit knowledge); and encouraging critical learning about statistics and pictorial representations.  相似文献

In response to the increasing recognition of the need for sustainable food systems, research on students’ and educators’ knowledge of food systems and sustainability more broadly has grown but has generally focused on what people ‘fail’ to understand. Moving away from this deficit approach, the present study used semi-structured interviews to explore how 12 pre-service teachers (PSTs) in the US consider sustainability in terms of the trade-offs – or concurrent costs and benefits – associated with using different agricultural resources over short, medium, and long terms. Drawing upon the constructs of framing, metacognition, and complex causality, the study found that the majority of PSTs referred to indirect experiences of seeing or hearing about agricultural resources to demonstrate stable knowledge of short-term trade-offs and construct tentative knowledge about medium-term trade-offs. Few described long-term trade-offs. Most participants also acknowledged some gaps in their knowledge in discussing trade-offs across the different time scales. Findings suggest the importance of leveraging and building upon educators’ (and ultimately students’) prior experiences to build their understanding of complex trade-offs that underlie food systems. The study also illustrates the value of using the concept of trade-offs across time scales to explore people’s conceptions and understandings of sustainability.  相似文献

This study explored both universal features and cultural variation in maternal speech. Japanese and American mothers' speech to infants at 6, 12, and 19 months was compared in a cross-sectional study of 60 dyads observed playing with toys at home. Mothers' speech in both cultures shared common characteristics, such as linguistic simplification and frequent repetition, and mothers made similar adjustments in their speech to infants of different ages. American mothers labeled objects more frequently and consistently than did Japanese mothers, while Japanese mothers used objects to engage infants in social routines more often than did American mothers. American infants had larger noun vocabularies than did Japanese infants, according to maternal report. The greater emphasis on object nouns in American mothers' speech is only partially attributable to structural differences between Japanese and English. Cultural differences in interactional style and beliefs about child rearing strongly influence the structure and content of speech to infants.  相似文献

ABSTRACT

Sport tourism is anticipated as one of the key industries that can vitalize a community with a wide variety of attractive natural resources. This research focusses on the relationship between tourists’ prior knowledge of the destination, destination reputation, and destination loyalty. Data were collected from domestic sport tourists who visited Niseko Adventure Centre during August, 2018 (N?=?221). Using confirmatory factor analysis and structural equation modelling, the results showed a significant relationship between prior knowledge, reputation, and loyalty, which explained 34% of the model. Sport tourism is expected to be one of the key elements to stimulate rural areas by utilizing their potential natural resources. In this research, we observed Niseko district to clarify the relationship between destination prior knowledge, reputation, and loyalty. As a result, we were able to conclude that, by focusing attention on information search processes, marketers can develop effective marketing strategies.  相似文献

The aim of this study was to determine the mechanical variables that govern success of the Hecht vault. The participants were 122 male gymnasts from 30 countries performing the vault at the 1995 World Gymnastics Championships. The vaults were filmed using a Photosonics 16-mm motion picture camera operating at 100 Hz. Approximately 80 frames were digitized for each vault analysed. The method of Hay and Reid was used to develop a theoretical model to identify the mechanical and physical variables that determine linear and angular motions of the vault. Correlational analysis was used to establish the strength of the relationship between the causal mechanical variables identified in the model and the judges' scores. Significant correlations (P < 0.005) indicated that the following were important determinants of success: large horizontal and vertical velocities at take-off from the board and the horse; large vertical and angular distances of pre-flight; large vertical impulses of high force and short duration exerted on the horse and the resulting large changes in vertical velocity on the horse; and large horizontal and vertical distances and long times of post-flight. Of the 18 significant variables identified in the present study, the angular distance of pre- and post-flights, the horizontal velocity and angular momentum at take-off from the horse, and the average moment of inertia and duration of post-flight collectively accounted for 57% of the variation in the judges' scores.  相似文献

Purpose: Maintenance and enhancement of vascular endothelial function contribute to the prevention of cardiovascular disease and prolong a healthy life expectancy. Given the reversible nature of vascular endothelial function, interventions to improve this function might prevent arteriosclerosis. Accordingly, we studied the effects of a 6-month static stretching intervention on vascular endothelial function (reactive hyperaemia peripheral arterial tonometry index: RH-PAT index) and arterial stiffness (brachial-ankle pulse wave velocity: baPWV) and investigated the reversibility of these effects after a 6-month detraining period following intervention completion. Methods: The study evaluated 22 healthy, non-smoking, premenopausal women aged ≥40 years. Subjects were randomly assigned to the full-intervention (n?=?11; mean age: 48.6?±?2.8 years) or a half-intervention that included a control period (n?=?11; mean age: 46.9?±?3.6 years). Results: Body flexibility and vascular endothelial function improved significantly after 3 months of static stretching. In addition to these improvements, arterial stiffness improved significantly after a 6-month intervention. However, after a 6-month detraining period, vascular endothelial function, flexibility, and arterial stiffness all returned to preintervention conditions, demonstrating the reversibility of the obtained effects. Conclusion: A 3-month static stretching intervention was found to improve vascular endothelial function, and an additional 3-month intervention also improved arterial stiffness. However, these effects were reversed by detraining.  相似文献
