This study tested social cognitive career theory (SCCT) in the technological domain with 2,359 high-school students in Asturias (Spain). Path analyses were run to determine the influence of gender on the SCCT model and to explain the influence of personal (emotional state, gender-role attitudes), contextual (perceived social supports and barriers), and cognitive (self-efficacy beliefs, outcome expectations) variables on technological interest. The results almost entirely confirm the SCCT model for Spanish high-school students in both the boys’ and girls’ samples. Further, the results show that girls and boys do not differ significantly as far as the different variables are concerned.  相似文献

In this article, we provide a conceptual model for the design of instructional scenarios integrating hypervideo as an instructional tool. The model provides a structural aid for making design decisions about using hypervideo in instruction. We start by introducing the theoretical rationale for hypervideo as a tool, exploiting three different interactivity functions. We then examine the cognitive and socio-cognitive theories that can inform the design and usage of hypervideo. Next, we present the instantiation of these functions and theories in a software interface, after which we present the model, which is based on the following two layers of design decisions: the first pertains to the interactivity features and the second is connected with the instructional strategy. Three main design steps are presented in the form of guidelines, corresponding to a preparation phase, a production phase, and a use phase. Finally, a set of cases exhibiting exemplary implementations of a hypervideo-based instructional scenario are described.  相似文献

Elementary combinatorial problems may be classified into three different combinatorial models (selection, partition and distribution). The main goal of this research was to determine the effect of the implicit combinatorial model on pupils' combinatorial reasoning before and after instruction. When building the questionnaire, we also considered the combinatorial operation and the nature of elements as task variables. The analysis of variance of the answers from 720 14–15 year-old pupils showed the influence of the implicit combinatorial model on problem difficulty and the interaction of all the factors with instruction. Qualitative analysis also revealed the dependence of error types on task variables. Consequently, the implicit combinatorial model should be considered as a didactic variable in organising elementary combinatorics teaching.  相似文献

The need of a guided and supervised learning has become the cornerstone of the new model of higher education. One response to such need has been the introduction of mentoring programs to facilitate student learning and to provide guidance. In this way, the main aim of our study is to determine the extent to which the implementation of information technology (IT) into a traditional mentoring program, improves students’ global satisfaction, and therefore its effectiveness. A survey was conducted of program participants’ overall satisfaction with the mentoring and also with each of the activities carried out. We concluded that the inclusion of IT in a traditional (face-to-face) mentoring model increases overall student satisfaction with the program, and thus its effectiveness. The findings obtained can serve as a resource to clarify the importance of educational interventions in the field of student guidance, to design new mentoring programs and to improve existing ones.  相似文献

This paper provides an overview of research on veteran teachers and teacher identity. It analyses issues at the personal, situated and professional levels that have been shown to impact on veteran teachers’ identities. The search included empirical studies published in peer-reviewed journals between 2005 and 2016. In total, 19 papers were analysed. Findings revealed that many studies focused on veteran teachers’ resilience. Issues concerning veteran teachers’ identities are key to understanding why they remain in the profession and are able to sustain their motivation and commitment over time. Many veteran teachers portrayed in the literature built on their confidence regarding their professional competence and relied on internal and external issues to maintain their motivation and commitment to teaching. The role of emotions in the transformation of veteran teachers’ identities and the permeable boundaries of the personal, situated and professional scenarios influencing veteran teachers’ identities are highlighted in the paper.  相似文献

This article advances current conceptions of teacher activism through an exploration of the social justice dispositions of teachers in advantaged and disadvantaged contexts of schooling. We interrogate the practices of teachers in a government school, with a high proportion of refugee students and students from low socio-economic backgrounds, in a high-fees, multi-campus independent school, and in a disadvantaged Systemic Catholic school to illustrate how Bourdieu’s notion of dispositions (which are constitutive of the habitus) and Fraser’s distinction between affirmative and transformative justice are together productive of four types of teacher activism. Specifically, we show that activist dispositions can be characterised as either affirmative or transformative in stance and as either internally or externally focused in relation to the education field. We argue that the social, cultural and material conditions of schools are linked to teachers’ activist dispositions and conclude with the challenge for redressing educational inequalities by fostering a transformative activism in teachers’ practices.  相似文献
