Effects of Group Formation on Student Satisfaction and Performance: A Field Experiment
2021
This study analyzes the relation of group formation on outcomes of a 4-week online course for prospective students. Group formation was experimentally manipulated based on predefined criteria, personality traits conscientiousness and extraversion. As research questions, groups were considered advantageous if they were formed (a) heterogeneously in extraversion, and (b) homogeneously in conscientiousness. As a result, no uniform outcome was identified. Most variance could be explained on group level, but no significant main effect for experimental grouping was found. Significant interaction between both main effects hint that the results do not provide final answers, but guidance for furthe…
Pedagogical translation, subtitles and ICTs: collaborative projects in L2classroom
2017
[EN] With this paper we offer a contribution to the debate on the importance of translation for learning a second language in the classroom. We exemplify its use as a didactic resource and as a learning tool. We show the methodological bases for a proposal consisting of three collaborative translation projects. This projects were carried out in higher education, namely in a Catalan as a Foreign Language (CLE) classroom at the Université de Picardie Jules Verne (France) in face-to-face and virtual scenarios. These practices are grouped into three different didactic sequences that deal with a given discursive genre –a music video, a commercial and a recipe– and that are realized as a teamwork.
Collaborative Problem Solving in Finnish Pre-service Teacher Education: A Case Study
2017
This chapter provides results from a case study utilising the ATC21STM assessment portal in the context of pre-service teacher education in Finland. The results from the portal are combined with a questionnaire regarding teamwork and collaboration dispositions. Twenty-four pre-service teachers completed both these measures. The students of this study were following two divergent teacher education programs that had different profiles in terms of their study contents and methods of studying. The participants of both groups tended to be highly disposed to collaborate and work in teams, and their collaborative problem solving skills can be described as very good. The participants’ measured soci…
3D high definition video coding on a GPU-based heterogeneous system
2013
H.264/MVC is a standard for supporting the sensation of 3D, based on coding from 2 (stereo) to N views. H.264/MVC adopts many coding options inherited from single view H.264/AVC, and thus its complexity is even higher, mainly because the number of processing views is higher. In this manuscript, we aim at an efficient parallelization of the most computationally intensive video encoding module for stereo sequences. In particular, inter prediction and its collaborative execution on a heterogeneous platform. The proposal is based on an efficient dynamic load balancing algorithm and on breaking encoding dependencies. Experimental results demonstrate the proposed algorithm's ability to reduce the…
Análisis de la construcción de entornos virtuales en los “Centros Educativos Inteligentes”
2013
El propósito de este artículo es plantear una metaevaluación de los primeros resultados obtenidos en un proyecto de investigación sobre la iniciativa ministerial Escuela 2. 0. en la que han participado 12 universidades. Nuestra aportación se centra en el análisis de cuatro estudios de casos, todos ellos Centros Educativos Inteligentes de la Comunidad Valenciana. Con los datos e información recabada se inicia el tratamiento de la muestra con una metodología mixta para analizar cómo estos centros se van transformando progresivamente en entornos virtuales de enseñanza y aprendizaje en colaboración. Transformación en la que la micropolítica de estas organizaciones es tanto o más relevante que l…
Collaborative Musical Creativity between Students and Adults: The Sonorous Paella
2021
While creativity is a key element of contemporary curriculum frameworks around the world, it is still insufficiently fostered in formal education settings. This study analyzes a project for collaborative musical creativity, entitled The Sonorous Paella. Participants (N = 12) were eight Year 4 secondary students, two professional musicians, an artist-in-residence, and a music teacher. Drawing on a graphic musical score, the participants worked together for 1.5 months to produce a group composition and performance. They were provided with various sound producers (instruments, everyday objects, technological devices) and were encouraged to flexibly utilize the physical space to maximize collab…
Reflection Assignment as a Tool to Support Students’ Metacognitive Awareness in the Context of Computer-Supported Collaborative Learning
2021
The present study explores the potential of a reflection assignment as a tool for supporting master’s degree students’ metacognitive skills in the context of computer-supported collaborative learning (CSCL). The research question (RQ) is formulated as follows: How does a regularly submitted reflection assignment support the development of students’ individual metacognitive awareness in the context of CSCL? The empirical data is a text corpus (7878 words) extracted from individual students’ (N = 13) reflection assignments (N = 65) submitted during one semester. Qualitative content analysis was employed to analyze the data. The results demonstrate that by the end of the course, the students s…
LeSSS: Learned Shared Semantic Spaces for Relating Multi-Modal Representations of 3D Shapes
2015
In this paper, we propose a new method for structuring multi-modal representations of shapes according to semantic relations. We learn a metric that links semantically similar objects represented in different modalities. First, 3D-shapes are associated with textual labels by learning how textual attributes are related to the observed geometry. Correlations between similar labels are captured by simultaneously embedding labels and shape descriptors into a common latent space in which an inner product corresponds to similarity. The mapping is learned robustly by optimizing a rank-based loss function under a sparseness prior for the spectrum of the matrix of all classifiers. Second, we extend …
Collaborative Content Downloading in VANETs with Fuzzy Comprehensive Evaluation
2019
Vehicle collaborative content downloading has become a hotspot in current vehicular ad-hoc network (VANET) research. However, in reality, the highly dynamic nature of VANET makes users lose resources easily, and the transmission of invalid segment data also wastes valuable bandwidth and storage of the users&rsquo
The wheel of collaboration tools
2006
Paper from the 2006 20th anniversary conference on Computer supported cooperative work We present a holistic framework for analyzing and specifying collaboration solutions, developed by an oil and gas company in response to practical needs in supporting integrated collaboration and information management. A typology of collaboration tool capabilities, termed the Wheel of Collaboration Tools (WCT), is described. We assess its contributions, and discuss areas of application and potential further development. Our intent is to stimulate discussion and research related to this type of collaboration modeling.
