In this article, we present the results of a research study that explores secondary students’ capacity to perform translations of algebraic statements between the verbal and symbolic representation systems through the lens of errors. We classify and compare the errors made by 2 groups of students: 1 at the beginning of their studies in school algebra and another 1 completing their studies on algebra in compulsory education. This comparison allows us to detect errors which require specific attention in instruction due to its persistence and to identify errors that disappear as students advance in their study of algebra. The results and conclusions have a pedagogic value to inform instruction and also lead to backed conjectures and research questions to push forward research on student’s translation capacity and students’ knowledge of algebraic symbolism. 相似文献

Many mathematics education researchers have suggested that asking learners to generate examples of mathematical concepts is
an effective way of learning about novel concepts. To date, however, this suggestion has limited empirical support. We asked
undergraduate students to study a novel concept by either tackling example generation tasks or reading worked solutions to
these tasks. Contrary to suggestions in the literature, we found no advantage for the example generation group on subsequent
proof production tasks. From a second study, we found that undergraduate students overwhelmingly adopt a trial and error approach
to example generation and suggest that different example generation strategies may result in different learning gains. We
conclude by arguing that the teaching strategy of example generation is not yet understood well enough to be a viable pedagogical
recommendation. 相似文献

The field of education has become comfortable in its use of the construct urban to describe particular schools in particular
metropolitan places. This article argues that the construct has come to signify not just place but also to denote particular
meanings of ‘urban’ populations. It analyzes how literary and social-scientific practices converged to anchor this construct
paradigmatically in the registers of educational practitioners and researchers. Drawing from cultural geography, the article
then demonstrates why the framework of the urban, and its other implicit pole the suburban, is no longer satisfactory for
conceptualizing empirical questions about metropolitan schools. Lastly, the author identifies and discusses exemplars within
the field of educational research that help us to remap our theoretical and empirical work. 相似文献

Schools alone cannot reverse the high rates of school failure in the poorest communities in Europe; they need the contributions of the entire community. Coordination between families, the larger community, and the school has proven crucial to enhance student learning and achievement, especially for minority and disadvantaged families. However, families from such backgrounds often participate in their schools only peripherally because the schools take a ‘tourist’ approach, call parents to inform them about school projects and teachers' programmes, or consult them about decisions to be made by professionals, rather than engaging them in their children's education. In contrast, the INCLUD-ED project studied schools across Europe whose students are culturally diverse and from low SES backgrounds; here, the communities are deeply involved in the schools and the students do well academically. This article focuses on three strategies used by these successful schools to engage immigrant and minority community members in more active, decisive, and intellectual ways and thus have greater impact on the school and the students' learning. It also describes some specific practices of involvement grounded in those strategies and the improvements they generate. Though the schools studied use different practices, the three strategies have been found to contribute to a transformative result in all schools: moving minority and disadvantaged families from the periphery of school participation to the centre.

Guidance has a role to play in helping older workers to lead meaningful and fruitful lives; inside, outside, on the edge of
the labour market, or in voluntary work with examples from two very different European countries: Denmark and Spain. This
paper aims to draw attention to older workers guidance from an economic policy approach. It will be demonstrated that there
is a need for more policy making for older workers’ guidance in both countries. 相似文献

Despite the potential advantages of instructional explanations, evidence indicates that they are usually ineffective. Subsequent
work has shown that in order to make instructional explanations effective indeed, one successful strategy is to combine them
with indications of the limitations in learners' understanding that they are intended to revise, which makes learners deeply
process the explanations. We explored whether this is so for both learners with low and those with high prior domain knowledge.
In one experiment, 77 participants with low and high prior knowledge learned about plate tectonics from a multimedia presentation.
In addition to the presentation, half the participants received instructional explanations combined with indications, whereas
the rest received instructional explanations with no indications. After using the materials, the participants solved retention
and transfer tests. Results showed that low prior knowledge learners learned more from explanations including indications
of their misunderstandings, whereas high prior knowledge learners profited from instructional explanations either with or
without the indications. We discussed theoretical and practical implications. 相似文献

The aim of this research was to determine whether the new geographic information technologies, included as teaching objectives in the new European Space for Higher Education Engineering degrees, develop spatial abilities. Bearing this in mind, a first year seminar using the INSPIRE Geoportal (Infrastructure for Spatial Information in Europe) was designed, involving 46 engineering students from the University of La Laguna. The spatial orientation ability development was analysed through statistical inference methods, using the Perspective Taking/Spatial Orientation Test. 相似文献

This paper describes the experience of an introductory discipline to the engineering curricula at the Brazilian Federal University of ABC (UFABC). The university offers a common basic curriculum that must be accomplished by every student and can be followed by professionalising courses. The discipline ‘Introduction to Engineering’ presents the basis of the engineering career, methods and thinking together with professional commitments and regulations. The objective is to help students to consciously choose their careers, minimising the precocity problem in deciding a professional future. The discipline methodology includes activities proposed by the TryEngineering website and from Brazilian engineering councils. Lectures with invited professors introduce UFABC engineering specialities: Aerospace, Bioengineering, Energy, Environmental & Urban, Information, Instrumentation & Automation & Robotics, Management, Materials. This paper reports the proposed activities, results obtained by the students, a methodology critical analysis and the impacts on the following steps of students embracing an engineering career. 相似文献
