Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective. 相似文献

ABSTRACTThe metaphor of the leaking pipeline is sometimes used to suggest that some students are lost for STEM as they advance through the educational system. This paper follows a cohort of upper-secondary school students with an interest in STEM from 18 months before their completion of upper-secondary until three years after their completion. Adopting a mixed-methods design, it follows the students' reflections and interests concerning their choice of higher education programme within and/or outside STEM. Only 22% of the students expressed the same interest during the whole period, and 56% changed between different groups of studies, e.g. between STEM and HEALTH. The students' trajectories showed that the leaking-pipeline metaphor is misleading because it suggests a linear and one-way movement, while there were students moving in as well as out of STEM trajectories. The students’ reflections showed identity issues at the level of ego identity, the personal identity and the social identity (Coté and Levine). Particular incidents in the students’ lives and in the outreach programme they were involved in sparked interests and reflections. These incidents should be considered as elements in a continuous reflection concerning who they are and where they would like to go rather than as critical moments. 相似文献

To support the national and international aims of inclusion, special teacher training in Sweden was replaced in 1990 by special educator training. These special educators would supervise the teachers in their school and would not exclusively teach students. The aim of this study was to investigate what the principals of 14 municipal compulsory schools in Stockholm County thought about the organisation and realisation of special education in 1996 and 2006 respectively. According to the results, there were fewer segregated groups in these schools in 2006, but an increasing number of students were placed in segregated groups that were common to several schools or municipalities. Principals at schools with teaching teams usually saw the special educator as a coordinating and supervising resource while others preferred the special teacher function. The former approach led to a more inclusive school and the latter in the direction of exclusion. 相似文献

只要提起"动手术",很多人都会毛骨悚然。然而却有越来越多人为了"变美"而甘愿挨刀子,在整形手术从拒绝到争议再到逐渐被接受的这个过程中,我们看到了技术的进步,和人们更加开放包容的态度。但这是否就意味着我们可以无条件地接受整形?做整形手术的人数在不断增加,但没有人会对此扬起眉毛啧啧称奇。去年英国"治疗"("治疗"一词似乎不太合适,但不管了)了50,122名整形人士,而其中90%是女性,同样也 相似文献

Academic development recognizes the strengths of communities, such as communities of practice or learning communities, in providing academics with supportive environments for the development of teaching. The problem academic development faces is that not enough academics are involved in these communities. Instead of trying to interest academics in joining communities, this research looks at the existing contexts around academics, which it refers to as ‘teaching groups’. It is proposed that every academic involved in teaching belongs to at least one teaching group, formed by colleagues teaching in the same course, degree or subject and that teaching groups form relevant contexts for engagement with teaching. The research investigates how teaching groups compare to communities and finds that less than half of teaching groups named by participants have strong community characteristics, indicating large space for improvement in the remaining majority of groups. The suggestion is made that identifying teaching groups across an institution might provide a promising starting point for engaging a majority of academics and working with these academics towards increased interaction on teaching in open and trusting collegial atmospheres. 相似文献

In educational environments, monitoring persons' progress over time may help teachers to evaluate the effectiveness of their teaching procedures. Electronic learning environments are increasingly being used as part of formal education and resulting datasets can be used to understand and to improve the environment. This study presents longitudinal models based on the item response theory (IRT) for measuring persons' ability within and between study sessions in data from web-based learning environments. Two empirical examples are used to illustrate the presented models. Results show that by incorporating time spent within- and between-study sessions into an IRT model; one is able to track changes in ability of a population of persons or for groups of persons at any time of the learning process. 相似文献

We digitized three years of Dutch election manifestos annotated by the Dutch political scientist Isaac Lipschits. We used these data to train a classifier that can automatically label new, unseen election manifestos with themes. Having the manifestos in a uniform XML format with all paragraphs annotated with their themes has advantages for both electronic publishing of the data and diachronic comparative data analysis. The data that we created will be disclosed to the public through a search interface. This means that it will be possible to query the data and filter them on themes and parties. We optimized the Lipschits classifier on the task of classifying election manifestos using models trained on earlier years. We built a classifier that is suited for classifying election manifestos from 2002 onwards using the data from the 1980s and 1990s. We evaluated the results by having a domain expert manually assess a sample of the classified data. We found that our automatic classifier obtains the same precision as a human classifier on unseen data. Its recall could be improved by extending the set of themes with newly emerged themes. Thus when using old political texts to classify new texts, work is needed to link and expand the set of themes to newer topics. 相似文献

Understandings of young children as active and capable citizens, while evident in discourses of early childhood education and research, are not widely reflected in the policy for the early years of schooling in Australia. This paper makes an analysis of the gaps and tensions between discourses of young children as active citizens and policy for citizenship education at the national level in Australia and at the Queensland State level. There is a widespread discourse within early childhood that regards young children as citizens and democratic participants in their own lives, as a reflection of the oft-cited Article 12 in the UN Convention on the Rights of the Child. However, educational policy and curriculum for citizenship in Australia, by and large, adheres to age and stage understandings of children that deem young children unable to conceptualise and/or articulate ideas of what it means to ‘be a good citizen’. We ask which discourses are being harnessed in educational policy for citizenship in Australia, what discourses are silenced or ignored and what this tells us about how young children are thought about in Australian politics and education. 相似文献
