This paper proposes that Kelly's Personal Construct Psychology deserves examination as a constructivist basis for science
teaching and learning. It argues that because of the explicit nature of the psychology, the clear definition of learning and
meaning and the integration of affective, psychomotor and cognitive dimensions of learning, the psychology has much to offer
science education. 相似文献

本文对秦始皇兵马俑博物馆室内采集的长短期降尘、大气悬浮颗粒物和彩绘漆层进行了SEM-EDX研究,在大气悬浮颗粒、短期和长期降尘中,含硫颗粒的粒径分别为0.9~22.8μm、1.0~29.0μm和1.2~37.7μm,多为石膏与粘土或石英以内部混合的状态存在。降尘中的附着型絮状硫酸钙多于大气悬浮颗粒物中,显示降尘和大气中的二氧化硫发生了累进的化学反应。彩绘漆层表面的坑和裂隙附近观察到原位生长的硫酸钙晶体,显示漆层材料或降尘颗粒物与大气二氧化硫之间的酸化学反应,可能是彩绘漆层表面受侵蚀形成微小坑和裂隙的原因之一。 相似文献

Delivering public services through the SMS channel is popular in developed and developing countries, and it has demonstrated its benefits. However, citizens' acceptance of the services is still an issue. This paper presents a study on user acceptance of SMS-based e-government services. Constructs of the proposed model were derived from a survey on citizens' motivations for using SMS-based e-government services (142 respondents from 25 countries), prominent theories on individual acceptance of technologies, and current studies on user acceptance of SMS and e-government services. The model was validated using data from 589 citizens in three cities in Indonesia, who are non-adopters. The relationships between the factors then were compared with data from 80 adopters of SMS-based e-government services in Australia. The proposed model explains what factors influence non-adopters to accept SMS-based e-government services, and the comparison explains the relative importance of the factors for the adopters. The findings are promising for governments who wish to evaluate a new SMS-based e-government system very early in its development in order to assess potential acceptability and for governments who would like to diagnose the reasons why an existing SMS-based e-government service is not fully acceptable to citizens and to take corrective action to increase the acceptability of the service. 相似文献

AbstractIn two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design. 相似文献

How can we use ICT to enhance the quality of pupil learning? The case study below deliberately embedded ICT within the context of an existing scheme of work to develop 11–12 year olds’ understanding of the skills and processes of historical investigation. It also mapped onto the existing teaching styles of the teachers involved, and reflected their orientation—beliefs and values. The role for the ICT was to present the pupils with a problem that would intrigue, excite and motivate them. Accordingly, we asked them to act in role as assistants to Harry and Hermione in investigating the strange death of Sam Woodhouse in 1822. The pupils carried out the investigation using a hyperlinked set of clues. They had undertaken two identical kinds of investigation earlier in the year. One was a murder mystery, the other the disappearance of the Princes in the Tower in 1483. For both these mysteries the clues were on cards. Comparisons of the results of the ICT mystery with those of the earlier two investigations suggest that the hyperlink version was equally effective in terms of developing understanding, with some clear advantages in developing pupils’ overall understanding of the problem and ability to make links between disparate clues and pieces of information. 相似文献

At colleges and universities across the United States, teacher preparation programs are increasingly required to prepare teachers for culturally and linguistically diverse student populations. Teacher education programs have responded by incorporating fieldwork experiences and curricular requirements that include a social justice and multicultural education focus. One key individual is uniquely positioned to reinforce and connect coursework with classroom practice during the teacher candidate’s practicum experience: the university supervisor. Our research team focused on the supervisors and their understandings of culturally responsive pedagogy (CRP) in order to better support them as they worked with teacher candidates to reinforce CRP in the classroom. Through interviews, field notes, and classroom observations, we examined language (words, phrases) that the supervisors used to talk about race and culture in relation to CRP. Our findings indicate a tendency to redirect conversations about race and culture to topics that they were more versed on such as teaching to the whole child or addressing the needs of the individual student. We termed this linguistic move the racial redirect, which emerged in language that (1) simplified the meaning of CRP and (2) made CRP seem like an unexpected or chance event in teaching. 相似文献

There was extensive mutual influence between BBC Local Radio and Independent Local Radio (ILR), particularly during the set-up periods for both systems. Although they competed for locations and frequencies, often fiercely, they developed through a single governmental mechanism and came to feel at times a close affinity. Had the proposals of the Annan Committee been agreed, that these 2 systems of local radio should be brought together under a single regulator, both could have benefited and the long-term prospects for local radio in the UK might have been enhanced. 相似文献
