Students of the subject had to learn how to prepare simple web pages, using HTML, CSS and JavaScript programming languages. To this end, flipped classroom technique was used to present the necessary contents, combined with an adaptation of Aronson's cooperative learning puzzle technique, used to carry out a group practice that reflected the knowledge acquired. It is worth mentioning, as a complement to the two techniques used, the use of an adapted assessment rubric, which was provided to the students at the beginning of the teaching block. The evaluation was carried out during two consecutive academic years, 2018/2019 and 2019/2020. There were important differences between the two studies: in the first study, students' previous self-assigned level was much higher (2.8 points as opposed to 1.4 points on a scale of 1 to 5). The other difference, even more relevant, was that in the second year all teaching was done at home, in a non-attendance format, on a mandatory basis, due to the period of confinement decreed by the state of alarm at that moment, because of the pandemic caused by the SARS-CoV-2 virus, popularly known as coronavirus. It is remarkable that, despite these differences, the students expressed their satisfaction with the learning acquired and with the tasks performed in both cases. The techniques used were well-appreciated, in first year more than in the second, and especially flipped classroom. Scores obtained were, in addition, always very relevant.","PeriodicalId":45123,"journal":{"name":"Education in the Knowledge Society","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43275903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El objetivo del presente análisis persigue que los estudiantes asuman el fracaso y el fallo como parte constitutiva e inevitable de su quehacer artístico y que lo acaben interiorizando como una fase más del proceso de creación. Para ello se ha optado por metodologías alternativas a la enseñanza tradicional de la pintura o el dibujo. En concreto, se ha apostado por la interacción entre artes plásticas y cine, buscando así la intermedialidad como recurso pedagógico privilegiado para que los estudiantes comprendan el lento proceso de maduración, reflexión –a base de caídas, fallos y rectificaciones– que requiere la creación de una obra artística. La incorporación de documentos audiovisuales, que recojan las reflexiones en primera persona de artistas reconocidos mientras trabajan, titubean y se plantean el siguiente paso a seguir, resultará esencial para que los estudiantes tomen conciencia del tiempo prolongado, y a veces improductivo, que requiere la gestación de una obra artística y para que no se conformen con los primeros resultados obtenidos. La reflexión meditada y la toma de conciencia de los fallos que se producen en todo proceso creativo son tareas necesarias para la superación de esos mismos fallos y para proporcionar aprendizaje a través de ellos. Se pone así en evidencia que el uso de esas metodologías intermediales genera consecuencias positivas para mitigar en los estudiantes la ansiedad por obtener resultados a corto plazo y tolerar mejor la frustración ante el fracaso para seguir creciendo como artistas.","PeriodicalId":45123,"journal":{"name":"Education in the Knowledge Society","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42115600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This creates challenges for education systems, as school must provide all students with the educational experiences that will enable them to develop the skills reflected in the profile of the 21st-century student on completion of compulsory schooling. It is up to teachers to find new ways of teaching, making the most of the resources and digital tools made available by mobile technologies. Technology can make a significant contribution to increasing students' motivation because it is closer to what they like and use in their daily lives. And this introduction of technology into the classroom can promote student-oriented teaching, which contributes to the development of skills such as autonomy, critical thinking and self-esteem. One of the areas that can contribute to this paradigm shift is the creation of experiences in immersive learning environments such as Transmedia Storytelling. Immersive learning environments can favour the creation and implementation of projects that promote reading skills in schools. This is the focus of this article. The aim of this study is to evaluate the impact of transmedia storytelling on the level of motivation of students and on the improvement of pedagogical practices implemented by the teachers involved. This case study was carried out in the subject of Portuguese in three 7th-grade classes of a school from the Médio Tejo region. The results obtained suggest a high level of motivation of students and teachers. The latter recognise that pedagogical routes using Transmedia Storytelling contribute to the motivation, autonomy and improvement of students' learning.","PeriodicalId":45123,"journal":{"name":"Education in the Knowledge Society","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49403521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, VCOPs are complex participation contexts due to their sociotechnical and sociocultural nature. Participation mechanisms, particularly Knowledge Sharing Behavior (KSB), have been studied from heterogeneous theoretical foundations and practical research methods. Therefore, a wide dispersion of factors and dimensions has been identified. This paper aims to present an overview that summarizes and systematizes the key drivers of KSB in VCOPs. This paper presents a systematic review of KSB in VCOPs, based on 42 studies retrieved from WOS, SCOPUS and Science Direct. The review was conducted using the PRISMA model. The selection and qualitative synthesis of articles was enriched using Nvivo for coding and analysis of the full text documents. The results suggest that KSB in VCOPs have a multidimensional and multifactorial character that includes personal, interpersonal, contextual, and technological factors. The typology of factors presented could serve in academic settings to conduct new theoretical or empirical research, or in practitioner settings to implement VCOPs in institutions across diverse sectors. New assessment instruments of KSB in VCOPs could be based on this typology.","PeriodicalId":45123,"journal":{"name":"Education in the Knowledge Society","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44477488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
