Formando las contribuciones del aprendiente en el aula de idioma extranjero: Una perspectiva desde el análisis de conversación

Indexación: Scopus.The present study sought to demonstrate the importance that the shaping of learner contributions has in the provision of opportunities for participation and learning in the EFL classroom. A particular set of interactional features that can shape learners' utterances were examined: scaffolding, requests for clarification and confirmation checks. These features have been found to promote language participation and learning from a classroom discourse perspective (Walsh, 2002; Walsh and Li, 2013; Can Daskin, 2014). The study was also informed by the sociocultural concept of learning as a social affair that is achieved through participation (Lantolf, 2000; Donate, 2000; Mondada & Pekarek, 2004). A Conversation Analysis (CA) methodology was used to analyse two extracts collected in EFL classrooms at a language institute in Santiago, Chile. Findings suggested that when teachers shape their learners' contributions by means of scaffolding, clarification requests and confirmation checks in a pedagogical environment that promotes conversation, participation and learning will likely be enhanced. © University of Chile.

Se utilizó una metodología de Análisis de Conversación (CA) para examinar dos extractos recogidos en aulas de inglés como lengua extranjera en un instituto de idiomas en Santiago de Chile. El análisis sugirió que si los profesores forman las contribuciones de sus alumnos adecuadamente y en un ambiente pedagógico que busque desarrollar fluidez, la participación y el aprendizaje serán facilitados.https://lenguasmodernas.uchile.cl/index.php/LM/article/view/4922

Integrating modes of policy analysis and strategic management practice : requisite elements and dilemmas

There is a need to bring methods to bear on public problems that are inclusive, analytic, and quick. This paper describes the efforts of three pairs of academics working from three different though complementary theoretical foundations and intervention backgrounds (i.e., ways of working) who set out together to meet this challenge. Each of the three pairs had conducted dozens of interventions that had been regarded as successful or very successful by the client groups in dealing with complex policy and strategic problems. One approach focused on leadership issues and stakeholders, another on negotiating competitive strategic intent with attention to stakeholder responses, and the third on analysis of feedback ramifications in developing policies. This paper describes the 10 year longitudinal research project designed to address the above challenge. The important outcomes are reported: the requisite elements of a general integrated approach and the enduring puzzles and tensions that arose from seeking to design a wide-ranging multi-method approach

Knowledge-aware Complementary Product Representation Learning

Learning product representations that reflect complementary relationship plays a central role in e-commerce recommender system. In the absence of the product relationships graph, which existing methods rely on, there is a need to detect the complementary relationships directly from noisy and sparse customer purchase activities. Furthermore, unlike simple relationships such as similarity, complementariness is asymmetric and non-transitive. Standard usage of representation learning emphasizes on only one set of embedding, which is problematic for modelling such properties of complementariness. We propose using knowledge-aware learning with dual product embedding to solve the above challenges. We encode contextual knowledge into product representation by multi-task learning, to alleviate the sparsity issue. By explicitly modelling with user bias terms, we separate the noise of customer-specific preferences from the complementariness. Furthermore, we adopt the dual embedding framework to capture the intrinsic properties of complementariness and provide geometric interpretation motivated by the classic separating hyperplane theory. Finally, we propose a Bayesian network structure that unifies all the components, which also concludes several popular models as special cases. The proposed method compares favourably to state-of-art methods, in downstream classification and recommendation tasks. We also develop an implementation that scales efficiently to a dataset with millions of items and customers

Number sense : the underpinning understanding for early quantitative literacy

The fundamental meaning of Quantitative Literacy (QL) as the application of quantitative knowledge or reasoning in new/unfamiliar contexts is problematic because how we acquire knowledge, and transfer it to new situations, is not straightforward. This article argues that in the early development of QL, there is a specific corpus of numerical knowledge which learners need to integrate into their thinking, and to which teachers should attend. The paper is a rebuttal to historically prevalent (and simplistic) views that the terrain of early numerical understanding is little more than simple counting devoid of cognitive complexity. Rather, the knowledge upon which early QL develops comprises interdependent dimensions: Number Knowledge, Counting Skills and Principles, Nonverbal Calculation, Number Combinations and Story Problems - summarised as Number Sense. In order to derive the findings for this manuscript, a realist synthesis of recent Education and Psychology literature was conducted. The findings are of use not only when teaching very young children, but also when teaching learners who are experiencing learning difficulties through the absence of prerequisite numerical knowledge. As well distilling fundamental quantitative knowledge for teachers to integrate into practice, the review emphasises that improved pedagogy is less a function of literal applications of reported interventions, on the grounds of perceived efficacy elsewhere, but based in refinements of teachers' understandings. Because teachers need to adapt instructional sequences to the actual thinking and learning of learners in their charge, they need knowledge that allows them to develop their own theoretical understanding rather than didactic exhortations

Topically Driven Neural Language Model

Language models are typically applied at the sentence level, without access to the broader document context. We present a neural language model that incorporates document context in the form of a topic model-like architecture, thus providing a succinct representation of the broader document context outside of the current sentence. Experiments over a range of datasets demonstrate that our model outperforms a pure sentence-based model in terms of language model perplexity, and leads to topics that are potentially more coherent than those produced by a standard LDA topic model. Our model also has the ability to generate related sentences for a topic, providing another way to interpret topics.Comment: 11 pages, Proceedings of the 55th Annual Meeting of the Association for Computational Linguistics (ACL 2017) (to appear

What is systemic innovation?

The term ‘systemic innovation’ is increasing in use. However, there is no consensus on its meaning: four different ways of using the term can be identified in the literature. Most people simply define it as a type of innovation where value can only be derived when the innovation is synergistically integrated with other complementary innovations, going beyond the boundaries of a single organization. Therefore, the term ‘systemic’ refers to the existence of a co-ordinated innovation system. A second, less frequent use of the term makes reference to the development of policies and governance at a local, regional or national scale to create an enabling environment for the above kind of synergistic, multi-organizational innovations. Here, ‘systemic’ means recognition that innovation systems can be enabled and/or constrained by a meta-level policy system. The third use of the term, which is growing in popularity, says that an innovation is ‘systemic’ when its purpose is to change the fundamental nature of society; for instance, to deliver on major transitions concerning ecological sustainability. What makes this systemic is acknowledgement of the existence of a systems hierarchy (systems nested within each other): innovation systems are parts of economic systems, which are parts of societal systems, and all societies exist on a single planetary ecological system. Collaboration is required across organizational and national boundaries to change the societal laws and norms that govern economic systems, which will place new enablers and constraints on innovations systems in the interests of sustainability. The fourth use of the term ‘systemic innovation’ concerns how the people acting to bring about an innovation engage in a process to support systemic thinking, and it is primarily this process and the thinking it gives rise to that is seen as systemic rather than the innovation system that they exist within or are trying to create. It is this fourth understanding of ‘systemic’ that accords with most of the literature on systems thinking published between the late 1970s and the present day. The paper offers an overview of what systems thinkers mean by ‘systemic’, and this not only enables us to provide a redefinition of ‘systemic innovation’, but it also helps to show how all three previous forms of innovation that have been described as systemic can be enhanced by the practice of systems thinking

Emerging cad and bim trends in the aec education: An analysis from students\u27 perspective

As the construction industry is moving towards collaborative design and construction practices globally, training the architecture, engineering, and construction (AEC) students professionally related to CAD and BIM became a necessity rather than an option. The advancement in the industry has led to collaborative modelling environments, such as building information modelling (BIM), as an alternative to computer-aided design (CAD) drafting. Educators have shown interest in integrating BIM into the AEC curriculum, where teaching CAD and BIM simultaneously became a challenge due to the differences of two systems. One of the major challenges was to find the appropriate teaching techniques, as educators were unaware of the AEC students’ learning path in CAD and BIM. In order to make sure students learn and benefit from both CAD and BIM, the learning path should be revealed from students’ perspective. This paper summarizes the background and differences of CAD and BIM education, and how the transition from CAD to BIM can be achieved for collaborative working practices. The analysis was performed on freshman and junior level courses to learn the perception of students about CAD and BIM education. A dual-track survey was used to collect responses from AEC students in four consecutive years. The results showed that students prefer BIM to CAD in terms of the friendliness of the user-interface, help functions, and self-detection of mistakes. The survey also revealed that most of the students believed in the need for a BIM specialty course with Construction Management (CM), Structure, and Mechanical-Electrical-Plumbing (MEP) areas. The benefits and challenges of both CAD and BIM-based software from students’ perspectives helps to improve the learning outcomes of CAD/BIM courses to better help students in their learning process, and works as a guideline for educators on how to design and teach CAD/BIM courses simultaneously by considering the learning process and perspectives of students. © 2018 The autho
