This paper aims to examine teachers’ use of strategies and approaches in integrating Plastic Resources Education (PRE) into primary school life in order to overcome the challenges encountered during implementation to promote environmentally friendly practices. Case studies with eight Hong Kong teachers from PRE-participating primary schools were invited to take part in focus group interviews, to explicate their personal stories and experiences associated with the PRE implementation in primary schools. Based on the data collected from the teachers’ sharing, several challenges which are commonly reported in the previous literature, including lack of time, shortage of manpower, and insufficient pupil engagement were found. The teachers tackled the barriers by using different strategies to improve pupils’ involvement as well as getting support from the relevant stakeholders of school management and parents. The case studies provide crucial and relevant information which can be used as a reference for other schools to integrate PRE more efficiently to facilitate learning. 相似文献

The formation of the South Korean identity through national curriculum in the South Korean historical context: Conflicts and challenges 总被引：1，自引：0，他引：1
This study explores how the South Korean identity has been formed and transformed by examining the Korean national curriculum in its historical context. The study first examines how the Korean identity, previously formed by traditional ethnic values, has been transformed during the period of national modernization. It then describes the efforts to form a Korean identity through national curriculum reform amid globalization, a phenomenon that has rapidly progressed in Korea since the 1990s. It also discusses the conflicts within and challenges to Korean identity in the Korean curriculum reform process. 相似文献

This study compared 3- to 4-month-olds' recognition of previously unfamiliar faces learned in a moving or a static condition. Infants in the moving condition showed successful recognition with only 30 s familiarization, even when different images of a face were used in the familiarization and test phase (Experiment 1). In contrast, infants in the static condition showed successful recognition only when the familiarization duration was lengthened to 90 s and when the same image was used between the familiarization and test phase (Experiments 2 and 3). Furthermore, presentation of multiple static images of a face did not yield the same level of performance as the moving condition (Experiment 4). These results suggest that facial motion promotes young infants' recognition of unfamiliar faces. 相似文献

The problem of source localization using time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) measurements has been widely studied. It is commonly formulated as a weighted least squares (WLS) problem with quadratic equality constraints. Due to the nonconvex nature of this formulation, it is difficult to produce a global solution. To tackle this issue, semidefinite programming (SDP) is utilized to convert the WLS problem to a convex optimization problem. However, the SDP-based methods will suffer obvious performance degradation when the noise level is high. In this paper, we devise a new localization solution using the SDP together with reformulation-linearization technique (RLT). Specifically, we firstly apply the RLT strategy to convert the WLS problem to a convex problem, and then add the SDP constraint to tighten the feasible region of the resultant formulation. Moreover, this solution is also extended for cases when there are sensor position and velocity errors. Numerical results show that our solution has significant accuracy advantages over the existing localization schemes at high noise levels. 相似文献

There are many contingent valuation (CV) studies to estimate the economic benefits of cultural heritage, but few provided advice on the design of financial products for cultural heritage assets. This paper conducted conjoint and willingness-to-pay (WTP) analyses for providing the design implication of these financial products. We calculated WTP for each attribute. The result of conjoint analysis shows that people prefer a short period of investment, high-expected rate of return and small amount of money invested. Only the amount invested and the rate of return on investment are significant to estimate WTP for these financial products. 相似文献

This study aims to examine the impacts of the inquiry learning strategies employed in a ‘Plastic Education Project’ on primary students' knowledge, beliefs and intended behaviour in Hong Kong. Student questionnaires and a test on plastic types were adopted for data collection. Results reveal that the inquiry learning strategies significantly improved students' knowledge of the types of plastic wastes and their corresponding beliefs. However, the strategies seemed not to change students' intended behaviour regarding plastic waste classification and management. The implications of the study for further learning and teaching in environmental education are discussed. 相似文献

The purpose of this study is to develop a valid and reliable scale to assess the level of English usage in daily life by students between 15 and 19 years of age, and to compare these students’ scale scores according to their achievement levels in an English course. Five hundred and ninety-five participants were randomly selected from a universe. Exploratory factor analysis results indicate that the scale has a two-factor structure, which explains 50.1% of the total variance. Exploratory factor analysis is validated by confirmatory factor analysis (NNFI: 0.97; CFI: 0.97; GFI: 0.87; AGFI: 0.84; RMSEA: 0.07; and Standardized RMR: 0.05). Cronbach Alpha coefficients for Factor 1 and Factor 2 were calculated as 0.90 and 0.86, respectively. Test–retest reliability coefficient of the scale is at the expected level (r: 0.86, p<0.001). Item discrimination results indicate that the upper 27% of participants have higher mean rank scores for each item on the scale and on the two factors, and that this difference is significant at the 0.01 level. Results of the study show that students’ level of English usage in their daily life is low, and that the students who use more English in their daily life have a higher achievement level in the English course. 相似文献

This article presents an examination of the effects of using an inquiry‐based learning pedagogy to teach ceramics to pre‐service teachers (my students) at the Hong Kong Institute of Education. At the beginning of the study the students were asked to conduct experiments on the properties of clay. The results indicate that half of them were able to transfer the knowledge and inquiry skills they had acquired from the experiments to their subsequent artwork production, but that the other half could not. I realised that the students needed more guidance to bridge the gap between their initial inquiries and their subsequent artistic creations. This could be done by explaining clearly the objectives of the inquiry‐based learning activities; employing strategies of assessment for learning: that is, setting explicit assessment criteria; involving the students in self‐assessments; and focusing more on methods of knowledge transfer and ways of bringing about improvements. 相似文献

Science as inquiry and mathematics as problem solving are conjoined fraternal twins attached by their similarities but with distinct differences. Inquiry and problem solving are promoted in contemporary science and mathematics education reforms as a critical attribute of the nature of disciplines, teaching methods, and learning outcomes involving understandings, attitudes, and processes. The investigative and quantitative processes involved in scientific inquiry include seeking problems, identifying researchable questions, proposing hypotheses, designing fair tests, collecting and interpreting data as evidence for claims, constructing evidence-based arguments, and communicating knowledge claims. Within this empirical context, science and mathematics come together to solve problems with evidence, construct knowledge claims, communicate claims, and persuade others that the claims are valid and useful. This study examined the intersection of inquiry and problem solving and the use of mathematics in 26 extracurricular open science inquiries. The category and the appropriateness of the mathematical procedures revealed these students used measurement, numeracy skills of counting and calculation, and tables and graphs in their science inquiries. It was found that most measurements in the science inquiries were used appropriately, but there is room for improvement with other mathematical procedures that involve higher-level thinking skills, such as analyzing and calculating numerical data and interpreting graphs and tables. The findings imply that mathematics and science are connected in inquiry and should be extended to solve real-life problems and that instruction should emphasize comprehending and interpreting data. 相似文献
