Teacher as creator: Orchestrating the learning environment to promote learner development

2022

Sociocultural theory (SCT) is a powerful basis for exploring and guiding L2 (second/foreign language) learner development. For the most part, however, the focus of classroom SCT-L2 has been on single activities, for example, teacher mediation of learners’ writing process or peer scaffolding. In this paper, we expand on these studies, building on Vygotsky’s (1997) metaphor of teacher as a creator of learner development. We propose how activities (1) where agency for guiding development lies with learners, (2) where the teacher takes the lead in guiding learner development, and (3) where opportunities for development emerge in dialogical interaction between the teacher and learners can be or…

Growing the practice of vocal sketching

2015

Sketch-thinking in the design domain is a complex representational activity, emerging from the reflective conversation with the sketch. A recent line of research on computational support for sound design has been focusing on the exploitation of voice, and especially vocal imitations, as effective representation strategy for the early stage of the design process. A set of introductory exercises on vocal sketching, to probe the communication effectiveness of vocal imitations for design purposes, are presented and discussed, in the scope of the research-through-design workshop activities of the EU project SkAT-VG

Cooperative sound design: a protocol analysis

2016

Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.

Sketching sonic interactions by imitation-driven sound synthesis

2016

Sketching is at the core of every design activity. In visual design, pencil and paper are the preferred tools to produce sketches for their simplicity and immediacy. Analogue tools for sonic sketching do not exist yet, although voice and gesture are embodied abilities commonly exploited to communicate sound concepts. The EU project SkAT-VG aims to support vocal sketching with computeraided technologies that can be easily accessed, understood and controlled through vocal and gestural imitations. This imitation-driven sound synthesis approach is meant to overcome the ephemerality and timbral limitations of human voice and gesture, allowing to produce more refined sonic sketches and to think a…

Continuum: A spatiotemporal data model to represent and qualify filiation relationships

2013

International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…

Observed Fitness May Affect Niche Overlap in Competing Species via Selective Social Information Use

2013

Social information transmission is important because it enables horizontal spread of behaviors, not only between conspecifics but also between individuals of different species. Because interspecific social information use is expected to take place among species with similar resource needs, it may have major consequences for the emergence of local adaptations, resource sharing, and community organization. Social information use is expected to be selective, but the conditions promoting it in an interspecific context are not well known. Here, we experimentally test whether pied flycatchers (Ficedula hypoleuca) use the clutch size of great tits (Parus major) in determining the quality of the ob…

Tin resonance-ionization schemes for atomic- And nuclear-structure studies

2020

This paper presents high-precision spectroscopic measurements of atomic tin using five different resonance-ionization schemes performed with the collinear resonance-ionization spectroscopy technique. Isotope shifts were measured for the stable tin isotopes from the $5{s}^{2}5{p}^{2}\phantom{\rule{0.28em}{0ex}}^{3}{P}_{0,1,2}$ and ${}^{1}{S}_{0}$ to the $5{s}^{2}5p6s\phantom{\rule{0.28em}{0ex}}^{1}{P}_{1},^{3}{P}_{1,2}$ and $5{s}^{2}5p7s{\phantom{\rule{0.28em}{0ex}}}^{1}{P}_{1}$ atomic levels. The magnetic dipole hyperfine constants ${A}_{\mathrm{hf}}$ have been extracted for six atomic levels with electron angular momentum $Jg0$ from the hyperfine structures of nuclear spin $I=1/2$ tin isot…

Engineering students' engagement with resources in an online learning environment

2018

International audience; This study explores engineering students' interactions with different resources in an online learning environment. The constituent resources of this environment involve MyMathLab which is an online interactive system for practicing mathematics, the tutorial videos, and the textbook. We conducted a qualitative case study to observe a small group of undergraduate engineering students interacting with the resources in a Calculus course. Employing the documentational approach to didactics, we identified several techniques while participants used resources to practice mathematics in MyMathLab environment. We discuss the pragmatic and epistemic value of the identified tech…
