Smartphones or laptops in the collaborative classroom? A study of video-based learning in higher education

  • Albó, Laia

Data de publicació electrónica: 26-11-2018, This paper explores how the use of smartphones vs. laptops influences students’ engagement, behaviour and experience watching academic videos in a collaborative classroom. Experiments were run in authentic teaching sessions with a total of 483 first-year higher education students. The methodology applied is a quasi-experimental design with post-test-only, being the independent variable, the device used to visualise the academic videos. Results indicate that the use of laptops has provided better results in terms of student’s engagement with the videos, their collaborative behaviour and satisfaction with the device. Hence, the findings of this research suggest that the type of mobile device used in activities that consider the use of videos in a collaborative class need to be carefully chosen to maximise the student’s comfortability – and in consequence, their engagement with the video-based learning activity and their positive behaviour and experience within the collaborative context., This work was supported by Ministerio de Ciencia y Tecnología [grant number MDM-2015-0502, TIN2014-53199-C3-3-R, TIN2017-85179-C3-3-R], Universitat Pompeu Fabra (UPF) [grant number PlaQUID2012], and RecerCaixa [grant number Communities of Teaching (CoT) Project].

In order to study the difficulties experienced during sentence comprehension in a foreign language (L2), we investigated semantic and world knowledge information retrieval in L2 comprehenders. Event-related potentials (ERP) were collected in late learners of English whose native language is Spanish, performing a sentence reading task in English. We investigated the mean amplitude of the P2 and N400 ERP components elicited by the critical word of sentences in three conditions: (1) correct,, (2) semantic violation, and (3) world knowledge violation (semantically acceptable but factually untrue). In the N400 window, ERP modulations elicited by semantic and world knowledge violations had similar amplitudes, as previously observed in L1 comprehenders. However, semantic violations failed to modulate P2 mean amplitude as it did in native speakers. These results suggest that, whilst L2 and L1 readers similarly integrate world knowledge and semantic information, L2 readers lack fast semantic access at around 200 ms after the onset of a critical word., This research was funded by grants from the Spanish Government (PSI2011-23033 and Consolider Ingenio 2010 CSD2007-00048), from the Catalan Government (SGR 2009-1521) and from the European Research Council under the European Community's Seventh Framework (FP7/2007-2013 Cooperation grant agreement 613465-AThEME).

Everyday use of computer-mediated communication tools and its evolution over time: an ethnographical study with older people

  • Sayago, Sergio
  • Sloan, David
  • Blat, Josep
Based on a 3-year ethnographical study, this paper discusses the prolonged use of computer-mediated communication (CMC) tools by approximately 400 older people in an adult education centre in Barcelona (Spain). Contrary to oversimplified views of older people as ICT users, this paper shows that they make a very rich use of CMC tools. Relevant elements of this use are their permanent desire to feel and be included, social, independent and competent ICT users. Despite the numerous interaction issues they face when using ICT, some are constant across different tools. Difficulties due to cognition limit their interactions more severely than those problems due to perceiving visual information or using the mouse. By examining the longitudinal aspect of the study, this paper addresses the evolution of technology use and whether the interaction issues that most of the current older people exhibit will be relevant when today’s more ICT literate young adults grow older. Interaction issues due to cognition are time-persistent, and independent of both experience and practice with ICT. Difficulties reading from the screen or using input devices are overcome with ICT experience. The strategies adopted by older people for coping with all these interaction issues are always targeted at feeling and being included, social, independent and competent ICT users. The results deepen current understanding of tools use in connecting older people with their social circles and the interaction issues most of them encounter when using ICT. The results also suggest that cognitive-related problems will be the most important ones in our work with the next generation of older people., We are indebted to Àgora and all our participants for allowing us to be part of their lives and share their experiences of using ICT with the rest of the world. We are also very grateful to Paula Forbes for improving our English and ideas, and the reviewers and editor of this journal for their careful, detailed and stimulating reviews. We also acknowledge the support from the Commission for Universities and Research of the Ministry of Innovation, Universities and Enterprise of the Autonomous Government of Catalonia.

Sustaining continuous collaborative learning flows in MOOCs: orchestration agent approach

  • Amarasinghe, Ishari

Collaborative learning spaces deployed in Massive Open Online Courses (MOOCs) provide productive social learning opportunities. However, sustaining collaboration in these spaces is challenging. This paper provides a classification of MOOCs participants based on their behavior in a structured collaborative learning space. This analysis leads to requirements for new technological interventions to orchestrate collaborative learning flows in MOOCs. The paper proposes the design of an intelligent agent to address these requirements and reports a study which shows that the intervention of the proposed orchestration agent in a MOOC facilitates to maintain continuous yet meaningful collaboration learning flows., This research is funded by Spanish Ministry of Economy and Competitiveness (TIN2014-53199-C3-3-R, MDM-2015-0502) and RecerCaixa (COT Project).

Se presentan los resultados del análisis de visibilidad de las sedes webs de museos de Cataluña realizado en 2013, a partir de los datos obtenidos por el explorador DigiDocSpider en Google. El objetivo global es obtener los datos necesarios para profundizar en la identificación de las buenas prácticas que ayuden a mejorar la visibilidad de cualquier sede web de museo. La metodología utilizada ha sido desarrollada en una doble perspectiva: comparativa y evolutiva con estudios anteriores. Se ha podido comprobar un incremento de visibilidad de los museos catalanes en el período 2006-2013; aunque se ha identificado una pérdida de visibilidad en los últimos cuatro años. En conclusión, los museos más grandes son los que mejor preparados están y mejores resultados obtienen mostrando una distancia muy significativa con los pequeños museos locales., The results of the 2013 analysis of visibility of the museum web sites of Catalonia are presented out of the data obtained by the explorer DigiDocSpider in Google. The main goal is to acquire the necessary data to deepen into the identification of good practices that help improve the visibility of any museum web site. The methodology has focused on a double perspective: comparative and evolutionary with previous research. An increase of visibility of the Catalan museums from 2006 to 2013 has been proved. However, a slight loss of visibility has been confirmed if we compare it to the period 2009-2013. As a conclusion, the biggest museums are better prepared and obtain better results, showing a very significant distance with those small local museums.

Museums and social media: Catalonia as a case study

  • Badell, Joan-Isidre
The main goal of this article is to describe the current situation of Catalan museums in social media. The study and analysis was developed following both a quantitative and a qualitative methodology, by creating parameters and indicators for scientometric purposes and by gathering and observing data from different platforms. Results showed that only 60% of Catalan museums present a social media profile of their own, and most of them are significantly lacking regarding feedback with their followers. A very heterogeneous situation was also detected in the Catalan museum system, which has a complex territorial organisation. Results also show that the introduction of state-of-the-art technologies is almost incidental. The discussion and conclusion sections also reflect on the presence and use of social media in Catalan museums, putting into question their communication strategies and plans, and how museums can communicate more effectively with their followers or visitors.

Este trabajo explora los usos, las prácticas y las percepciones que los docentes universitarios de Comunicación dan a las TIC. Los objetivos son, por un lado, reconocer los sentidos que los profesores del nivel superior atribuyen a la integración de las TIC en la enseñanza, y por el otro, discutir las oportuni- dades y barreras que genera esta integración en la preparación inicial de comunicadores. Para ello, aplicamos un cuestionario a una muestra representativa de docentes (N=104) de una universidad argentina y otra peruana, cuyos resultados fueron analizados cuantitativamente. Los hallazgos más relevantes indican que los docentes mantienen un vínculo recurrente con distintas herramientas digitales, aunque estas prácticas disminuyen en el caso de mediaciones que promueven capacidades creativas, experimentales y lúdicas. Paralelamente, se encuentran tensiones entre las posiciones docentes, que por un lado expresan valoraciones positivas de las herramientas digitales para la enseñanza, y por el otro no existe una convicción plena de la necesidad de actualizar los formatos y metodologías vigentes. De modo transversal los docentes advierten algunas dificultades que asocian a la integración de TIC y que posibilitan pensar desafíos a escala institucional., This paper explores the uses, practices and perceptions that communication professors give to ICT. The objectives are, on the one hand, to recognize the meanings that the professors give to the integration of ICT in higher education, and on the other, to discuss the opportunities and barriers that this integration generates in the initial preparation of communicators. We applied a questionnaire to a representative sample of professors (N=104) from two institutions from Argentina and Peru. The results were analyzedquantitatively. The most relevant findings indicate that professors maintain a frequent link with many digital tools, although these practices decrease in the cases of mediations that promote creative, experimental and playful abilities. At the same time, there are tensions between the professor’s beliefs: while they feel positive on the use of digital tools for teaching, there is still no full conviction of the need to update the current formats and methodologies. In a transversal way, teachers notice some difficulties regarding the integration of ICT, which lead to think about challenges at the institutional level.

Circulating small RNAs, including miRNAs but also isomiRs and other RNA species, have the potential to be used as non-invasive biomarkers for communicable and non-communicable diseases. This study aims to characterize and compare small RNA profiles in human biofluids. For this purpose, RNA was extracted from plasma and breast milk samples from 15 healthy postpartum mothers. Small RNA libraries were prepared with the NEBNext® small RNA library preparation kit and sequenced in an Illumina HiSeq2000 platform. miRNAs, isomiRs and clusters of small RNAs were annotated using seqBuster/seqCluster framework in 5 plasma and 10 milk samples that passed the initial quality control. The RNA yield was 81 ng/mL [standard deviation (SD): 41] and 3985 ng/mL (SD: 3767) for plasma and breast milk, respectively. Mean number of good quality reads was 4.04 million (M) (40.01% of the reads) in plasma and 12.5M (89.6%) in breast milk. One thousand one hundred eighty two miRNAs, 12,084 isomiRs and 1,053 small RNA clusters that included piwi-interfering RNAs (piRNAs), tRNAs, small nucleolar RNAs (snoRNA) and small nuclear RNAs (snRNAs) were detected. Samples grouped by biofluid, with 308 miRNAs, 1,790 isomiRs and 778 small RNA clusters differentially detected. In summary, plasma and milk showed a different small RNA profile. In both, miRNAs, piRNAs, tRNAs, snRNAs, and snoRNAs were identified, confirming the presence of non-miRNA species in plasma, and describing them for the first time in milk.

  • Mutation Consequences and Pathway Analysis Working Group of the International Cancer Genome Consortium
Genomic information on tumors from 50 cancer types cataloged by the International Cancer Genome Consortium (ICGC) shows that only a few well-studied driver genes are frequently mutated, in contrast to many infrequently mutated genes that may also contribute to tumor biology. Hence there has been large interest in developing pathway and network analysis methods that group genes and illuminate the processes involved. We provide an overview of these analysis techniques and show where they guide mechanistic and translational investigations., J.M.S. acknowledges support from the US National Cancer Institute (R01-CA180778 and U24-CA143858).
